>>2248608>https://wiki.cybsec.io/index.php/HamFAQ>>The wiki is down but is archived: https://archive.is/PjR5sThe wiki will probably never come back, but the archive remains.I am thinking of continuing the document and put it on Neocities, any inputs to what should be added?
>>2248608Please OP add that https://www.sigidwiki.com/wiki/Signal_Identification_GuideIt's great
>>2248651Not a bad idea.
>>2248651>>2248660It is already in the FAQ: https://archive.md/PjR5s
>>2248578For portable I use a kx3 + hardrock-50 in a custom manpack typically with an end-fed half wave. I've done daytime and nighttime NVIS on bands that are higher than local FoF2. If you already have a QRP rig then you should get a linear amplifier for it and find a way to keep it portable. I think that 35-50 watts into a tuned and efficient antenna is a reasonable lower limit for NVIS. 80 meters antennas are already huge, and I haven't even considered 160 meters portable. I would probably need multiple fiberglass poles to string it up. If you end up using a compromised antenna for 80/160 meters then you will probably want even more power. QRP die-hards will give you flack if you go with an amp but it makes it possible to operate in less than ideal conditions, or with antennas that are compromised for portability.
Gents, I use a random wire for swl'ing. I have had it stretched between 2 trees and results are fine. Is there any advantage to setting up vertically? I can go higher up on my property (mountain area) and hang it in a tree. What do you think? Waste of time? My goal is simply dxing as many stations as possible as far as possible.
>>2248751For reception, keep it horizontal, polarization is not a problem. Same for heigh, it doesn't matter that much, for emission, it would determine the angle of the main lobe, the lower the antenna is relative to wavelength, the higher the angle and te lower the distance.As long as you aren't polluted by electronics in the house, it's good.Do you ask stations for QSL cards ?
>>2248751verticals are better for dxing from a transmit pov. they give you a shallower angle of radiation (so i've been told) and you get some gain from them. but if your just swl then a vertical may not be your friend as they typically tend to be noisier on receive.i'd just stick with either a mag loop or stick a simple horizontal dipole up as high as you can possibly get it. if you want to get some good dx from some specific distant place you could start messing around with wire yagis or other high gain antennas but then your looking at alot of work, and figuring
>>2248608hey kiddo jump on grampa's lap and lets tune in tokyo!
Anyone have experience with Magloops on 40/80m? Thinking about getting one from chameleon
>>2248765For transmit or receive? If you're planning to transmit then don't because a reasonably sized magloop for those long wavelengths is wildly inefficient. Also beware of most of the stuff that chameleon sells
>>2248767I need a small portable package for 40/80m and a half wave dipole isnt going to work for me, magloop looked like it might be a good solution. I need to Tx and Rx
>>2248765>>2248769>random wire>9:1 unun>portable tunerThank me later. Why stick to 40/80?If you want to have something to work the lower bands, pick a length near 72'.
>>2248769Magloops were attractive to me too anon for portable long-wave operation but I ended up going with an end-fed half wave. I can toss one end into a tree or use a fiberglass pole if no trees available.For the loop antenna to have acceptable tx efficiency on 40-80 meters it needs to have a diameter in excess of 10 feet. Otherwise, you will turn most of your transmit power into heat. Explained in this video: https://www.youtube.com/watch?v=7N9O1QXII7s
>>2248354Different locations did not seem to affect it at all. It just randomly seems to come on and off at times. It may very well be random noise. On the plus side, it's interesting to spook businesses on their FRS radios. I'm going to add a counterpoise to it to see if it helps increase the range.
>>2248751Try it and see what happens.
Not sure if this question is still ham/radio related but i thought people might have deep knowledge on this topic here. As far as i understand, wire antennas can be used to receive signals from frequencies ~0 Hz to around 300 GHz (or somewhere before the infrared range)What can be used for way higher ones as THz/Phz? I know there's photo detector components with specialized small ranges such as 500-550 Thz, but if i were to receive transmission going as high as Petahertz range, is such thing even possible via normal electronics?Isn't that hitting the speed of light / electrons limits where such wavelengths would make any circuits fail? I know this has been done but i guess it's via downconverters or totally diff kind of methods, maybe same tech as used in fiber optics?
>>2248980Radio waves are defined to go as high as 300 GHz, but the practical limit on solid-state radio-frequency communications is the switching speed of the fastest transistors which is tens of gigahertz. There are faster transistors in university labs but they are irrelevant because you can't buy or use them. Radio waves between 300 MHz and 3 GHz are further classified as microwaves. At microwave frequencies, especially above 10-20 GHz, it is more practical to use physical structures to carry and manipulate the waves rather than circuits and cables. E.g. waveguides, traveling-wave tubes, filter cavities, horn antennas.Above 300 GHz (1mm wavelength) it transitions from microwaves to infrared light. There is no real boundary and the 300 GHz number was picked by scientists. At this point the wavelength is small enough that waveguides can no longer be used and optical components are used instead. E.g. lasers and phototransistors. To detect the lowest infrared wavelengths cryogenic sensors are required because the black-body radiation of room temperature objects falls into this range. There have been experimental laser communications between hams with a distance of tens of miles using FM-modulated laser beams and detectors.At terahertz and petahertz you are in the visible and ultraviolet categories which behave mostly the same way as infrared.However, everything above a few gigahertz is unable to penetrate objects so is useless for communications except point-to-point. Atmospheric absorption of certain wavelengths becomes a big limitation.
I'm looking to get into CB soon. How viable is a handheld radio with a long antenna? Im talking one of those 40 inch foldable ones. I ask becuase I don't really have that good options for mounting a permanent antenna anywhere, so I might as well go mobile.
I was setting up an AM loop antenna on my stereo amplifier, and was disapointed by the length. It barely reaches above the cabinet its in, and it's halfway behind the cabinet against the wall. I've been debating wether to get a longer wire antenna, or just splice the cable leading to the loop and lengthen it myself. I'm worried that splicing the wire will cause exposed wire to pick up noise from all the other equipment in the cabinet, even if the loop is farther away. I know another antenna would only be about $10 but I was hoping to avoid it.
>>2249040You can use it unfolded as a walkie talkie, that's all. The range will be a couple of kms in the open, less than that if there is anything like forest, hills...
>>2249052Ideally, you should solder the wires together. But if you have no access to a soldering iron or solder, splicing is okay. Just make sure you tape it up vrry well with electric tape.
>>2249052Adding wire will change the loop characteristics and cause more unwanted noise. You're better off by rotating the antenna for max signal on the station you're listening to. By all means try making it longer if you want, but don't expect stellar results.
Got my J-37 set up and ready to rock. The ¼" brass plate gives it a nice weight, even without any rubber feet it doesn't want to move around.
>>2248878Good to know, and thanks for following up! I need to do that mod one of these days.
>>2248608So I saw these Baofeng GT-22's mentioned in an earlier thread and ended up picking up a pair. $27 for two (not including a programming cable). You can get 4 for an even lower unit price. They are actually sort of cool. They're actually lighter than my cell phone, and about the same size. And the programming options are pretty good for a FRS radio. You can do split tones or configure an offset if you want. The provided programming software won't let you configure any channels in the 70cm band but you might be able to in CHIRP. I haven't tried yet.
>>2249725Picrel is the default channel configuration. I noticed that they set the interstitial channels set to HIGH power. Which is not legal unless HIGH power is 500 mW. Any thoughts on this? What are the chances that this radio actually puts out 2 watts as advertised?
After receiving my ham license, is my information permanently available on the FCCs website? What if I choose to cancel my license, is the information removed? I notice that I can still get information about expired/revoked/dead hams. Is it possible to have the information expunged after canceling the license?
>>2249609I'm pretty happy with how it came out. Especially for not having any power tool, and just some harbor freight chisels.I set it up, so if I go to do a POTA, I can take the key off, and put it back on the J47 leg mount too. I know the J37 isn't the best key in the world, but it's one hell of an upgrade from the key I took off my MFJ-557, and it works a lot better than my J-5-A.I've got a 1946 Vibroplex bug, and an Uni-715(in the mail), but straight key is just so much fun. Saving the bug for after I've made a few contacts. Still need to fully disassemble and throughly clean it. It's fully functional as is though, so I'm not too worried.
>>2249807I don't think it is anon. If you're worried about your address being avaliable, rent a P.O. box.
>>2249852DO you use your FT-891 in portable ? The specs says it draws 2 Amps in reception, is it true ? It looks like a lot for a small device with a reasonnable LCD screen
>>2249940I don't know what the draw on Rx is, but I get over five hours on a 20Ah battery with digital and SSB.
>>2249852Really nice job.>J47 leg mountThat's what I need too. But I haven't yet got a J37 key either.Also, brass knuckles are good for city POTA, but you may want something less close-quarter and more powerful for rural POTA.
>>2249852>>2250157>something less close-quarter and more powerfulforgot pic
>>2249858It's not really the address I'm worried about, that's already traceable from public records. It's more so having my name easily searchable and associated with this boomer activity. I use ham databases to cyber stalk people all the time, so I don't want that happening to me.
>>2250404>I use ham databases to cyber stalk people all the time>I don't want that happening to me
>>2250428It's a perfectly rational conclusion
>>2250464This. It shouldn't be allowed in the first place. I'm still getting junk mail from local clubs asking me to join.
>>2250157I don't have a boar, but I do have an attack goat and a nickle plated 1873.There's a ton of J37 with J47 leg mounts on ebay, some brand new. Think the DoD finally dermoed their supply
>>2250650>J37 with J47 leg mountsNow that brings back memories, especially that day when the radio had faulty grounding and RF power was brought to the leg mount. I had tuned the transmitter to power levels I had not seen before, brushed my left hand briefly against the leg mount and was immediately fried.Ah yes, those were the days.
>>2250650Nice Instructograph!>ton of J37 with J47 leg mounts on ebayI should get me one then, seen it in use by some French guy on some high altitude SOTA trip and it would come handy in the car too.
Anyone near STL?
Portable transcievers are straight forward. Who has a portable HF antenna that works well and can tell us about it? Everybody has a different system. Personally I like end fed half waves because the feed point location is convenient and the other end can be tossed into a tree or some other support.
>>2251498see >>2248773Never left me without QSOs. Drawback is you need a portable tuner. But can use any band you like. It seems to be better at wavelengths above 1.5x its length, i.e. with 72' it appears to be better at 30m and lower frequencies.Probably it's the strong directionality on the higher bands that makes it less useful there, but you can counter that hanging it over a pole/tree in inverted V shape.
>>2250650Open a box like that in public and people will dive for their phones and call DHS.>>2251498>Who has a portable HF antenna that works well and can tell us about it?You might want to check this:https://qrper.com/2021/10/new-n0sa-paddles-and-elecraft-ax1-showing-off-during-an-impromptu-pota-activation/
Is my Baofeng bricked? It started doing this after I left it in a hot car. It's not responding to Chirp either.
New ham here. I'm really trying to understand the nitty-gritty of how antennas work. Also must mention that I'm a complete n00b when it comes to electronics. I'm having a hard time finding material that explains exactly how antennas pick up transmissions at a given frequency. The general handbook kinda goes into it in the Yagi section but with me the more resources I can find the better I can understand something. I'm also having a hard time understanding how Yagi antennas work, specifically how the directors actually focus the signal in one direction. If any of you have good resources for that please link em! Also, what's a good, relatively cheap SWR meter you'd recommend a new ham getting? I want to build a tape measure Yagi and I just need something simple to test it.
>>2251790Have you tried a hard reset? Also try pulling the battery out for several hours.
Wouldn't rely on this in an emergency but it's a cheap setup to hear the truck drivers talking shit.
>>2251803To learn about antennas, start with a simple dipole and then the folded dipole. The Yagi builds upon that.
>>2251803this gif helped me understand yagis
>>2251832>Have you tried a hard resetI can't get into the menu.
>>2251898Hmm. Are you able to follow these instructions to reload the firmware?https://www.otleyradio.org/index.php/2016/05/05/fixing-a-bricked-baofeng/If that doesn't work, I'm out of ideas. Baofeng support is pretty responsive. It would be worth reaching out to them before you throw the thing away.
>>2250814Thanks! It was a lucky find at a local antique store. It's a neat system, and the cable it comes with is in typical DoD fashion absurdly overdone (it's 18ga, fully insulated, 3/8" cable). All the new ones are driving the used one down in price, so you can get a fairly decent key without breaking the bank. >>2250800That sounds electrifying, bet you didn't make that mistake twice kek. >>2251690That'd be fun. Might have to try it sometime. Maybe at a Starbucks in Portland? Neat box, does the filename mean anything, or do you have any info on it?
>>2251941>Neat box, does the filename mean anything, or do you have any info on it?I think this is it:https://hackaday.com/2019/11/11/a-mobile-terminal-for-the-end-of-the-world/
>>2250652This. What's up with so many zoom zooms afraid to be on a government database? You're already on a list bucko. Might as well make the best of it. What are they gonna do, show up to confiscate your radio? LOL
>>2251960There's a lot of schitzos on 4chin, that unironically think the FCC will v& them.
>>2251941>That sounds electrifying, bet you didn't make that mistake twice kek.It was RFtastic. It demonstrated the RF skin effect in ways I did not want. The repair shop was really bad so I treated the kits with much suspicion after that.
>>2251803>Also, what's a good, relatively cheap SWR meter you'd recommend a new ham getting?A nanoVNA will work as a cheap antenna analyzer. The interface isn't great but you'll be fine if you're not a retarded boomer
>>2248608Can anyone enlighten me on finding RFI from grow ops with an RTLSDR?grow ops meaning LED lights and HID lights
>>2251690That looks like a really cool project. The built in keyboard is a nice touch, the popularity of mechanical keys has really made building custom keyboards and keypads really easy. >>2251960Okay, bootlicker. Having a ham license is like coming out as gay. Sure it may sound like a good idea, and guberment might tell you it's okay, but it's not okay, it's fucking gay. I'm more concerned with schitzos and googlers. Ham radio people sketch me out. https://www.youtube.com/watch?v=UaNLCgAHMDM
>>2252076might be possible in the countryside but you would find ten thousand other sources of interference for every grow op. impossible in the city. I wouldn't worry about the feds finding your grow op that way anon
>>2252076The receiver is less of a problem, but you must build a nice, portable, highly directional antenna.Best to have a set with wider and narrower angles to change.

>>2251960They just want to scream naughty words at people and have no repercussions.
>>2251978Tx-ing, licensed or not, where you're not supposed to be or to intentionally screw with people will get you v&ed. Keep it civil and on the amateur bands and you'll be fine. Trying to intentionally obfuscate transmissions will also shine a light on you.
>>2252096>Having a ham license is like coming out as gay.>gubermentYou can be sure the gov. already has a file on you, buddy.
>>2252555>Tx-ing, licensed or not, where you're not supposed to be or to intentionally screw with people will get you v&ed.You mean a freedom loving good person could bait highly skilled but hostile thugs into a ambush by just teasing them on the radio? Oof those tax dollars for training and funerals will be costly.
>>2252720>bait highly skilled but hostile thugs into a ambushYou really haven't followed this general much, have you?
>>2252720depending on exactly what you are transmitting and on what frequency, yesbut definitely not any amateur bands
>>2250614man all you dudes complaining about getting junk mail from clubs and i never got one piece. i guess all the boomer clubs near me don't even bother.
>>2252552Problem? >>2252393Time skips were not covered on the general study guide. Is that something you figure out when you get amateur extra?

Haven't been into HAM for a few years, sold my HF rig a while ago. Still miss it desu but I needed the money at the time, Yaesu FT450D, great bit of a kit. How are the sunspots now? They were shit 5 years ago.
>>2253289The propagation is improving, FT-450D are great, and people know that, so they aren't cheap even used, you can maybe look for a Yaesu FT-900, a TS-50 with the tuner or an older rig like an ICOM IC-730 ?
Looks like 11 and 10 are open. Get transmitting fellas
>>2253430Now in the wake of the solar shit the geomagnetic field is unsettled and bands are no good :(Did you get to use it while it was good anon?"Unsettled to active conditions are expected on 16-17 Nov in response toCH HSS influence. 18 Nov is expected to see a return to quiet ambientconditions."
Seems the Radioberry is back on the shelves again, anyone here bought one?
South America is doing well today.>>2254061I've heard of these before and they look interesting, but looking at the schematics it's just a bare-bones direct conversion stage. So you still have to build an entire transceiver around it.
>>2254158It is a weak QRP and should work as is. Using DDS you don't need a filter bank. The only snag is that the signal is rather weak.
>>2253879Never use this chart, it is rarely accurate - yet qrz puts it front and center. Sometimes the bands legit open with those "poor" ratings. Sometimes sporadic E. I quick looking at this graphic years ago. Turn on your radio and tune the dial.
>>2254200Things that the Radioberry needs:-RX preamp and optional attenuators-band pass filters section-TX power amplifier to go from milliwatts to watts-TX/RX switch-low pass filters section going to combined antenna connector
>>2253879>Did you get to use it while it was good anon?Nah, i called CQ at least 5 times over 15 min and got nothing back. Could def hear the cb guys going off, and 1 or 2 guys on 10 trying to call as well. Everyone on 10 was more towards 3/2 but thats better than the usual nothing
Anyone play around with 3d printers? I'm trying to justify buying one.
>>2254458>i called CQ at least 5 times over 15 min and got nothing back.Do zoomers really?
>>2254665my only time with HAM is using webSDRs, but as a 3d printing fag I'd say anyone whos /diy/ minded *needs* a 3d printer. its definitely still not as straightforward as printing a document, even the nicest printer will have some learning curve, but its truly unmatched for hobbying. building jigs or brackets or whatever manually is complete ass when you can draw one in cad and then a printer shits it out while you do other things. its amazing
>>2254689Between ham, /k/, and having young kids who I'll try to drag into /diy/, I think I'm sold.I was eying the Anycubic Chiron, but people are suggesting I go with the Ender 3v2.Any thoughts on something in that price range for a broad use, starter printer?
Since all the answers are out there and the tests aren't monitored. should I create a bot to fill in all 250 tests?
>>2254697>Any thoughts on something in that price range for a broad use, starter printer?cheap printers can be good but they often have the worst QC, a crappy bowden coupler or bent z-screw can be a headache and cause problems. The prusa mini is actually a good quality printer on the high end of that price range, spec wise you get a much smaller build plate but a better hot end and actual QC.
>>2254388As it is it emits 100 mW. I am not sure how far that gets you with a tuned dipole.A 5W PA is designed that also does the TX/RX switch.Videos show the Radioberry gets along without RX preamp or filters.
>>2254771it's not very hard anon just learn the questions and you'll be better off
>>2254869Are they processes that are actually utilized anymore?I just passed a few Fema courses and an ARRL Emergency Comm course in a few hours. I have no interest or expectation that it'd ever be put into use, just did it out of boredom. Anyone have experience with the MARS or ARES memberships? I'm not a larping VHF autist that rides a bike.
>>2254915I've been shadowing my local ARES. Every week they meet on a repeater, and then break off to simplex to find what coverage they have without repeaters, and practice SOPs.
Just realized this is how i look when i mention radio as a hobby irl

Anybody have any experiences with HAMnets? I'm trying to set one up near where I am with New Packet Radio. I want to allow access to the main net with it. Is a reverse proxy the way to go with avoiding getting the FCC coming for my ass for the HTTPS encryption
>>2256119Still too fat to climb a hill to do a SOTA activation, boomer?
>>2256309Good argument! A self contradictory argument always wins the fight!
>>2256357These hands typed this post, pic related.
>>2256357Whatever you say, boomer. You might to try walking more often to places other than the bathroom and fridge. That way, you can do more than POTA activations from your handicap accessible vehicle.

Has anyone heard about the 1BCG special event coming up next month?Trying to learn my CW now so I can decode it if I hear it on 160.
>>2256733That's kind of cool>2021 marks the 100th year anniversary of the historic Transatlantic Tests. On December 11, 2021 The 1BCG replica transmitter will be operating as W2AN/1BCG on 1.821 MHz, plus or minus, using CW, from The Vintage Radio and Communications Museum of Connecticut. Transmissions from W2AN/1BCG will be one-way, just like the original transatlantic tests in 1921. You can get a SWL certificate for this Special Event by sending a copy of the transmitted message to 1BCG@AntiqueWireless.org
>>2256632You're welcome, it's almost like you have a real friend.
Falling for the HF mobile meme. Decided against tuner and whip since it works but is shit. Didn't really want just straight up hamsticks since they work but also not great. I looked a little into screwdriver antennas but motorized versions were on the expensive side and didn't see too many manually adjusted screwdrivers that seemed quality. After minimal research and letting the autism take over, bought some the standard Hustler resonators plus some other shit to have for an install similar to pic related. Allegedly more efficient than a plain old hamstick and also can get three bands instead of monoband since I'm retarded and don't care if my vehicle looks retarded too. Seemed like a decent enough compromise between price and quality/efficiency. Decent idea or did I get hustled by the Hustler
>>2255982Same as every technical hobby. It draws in people with the tism and the majority with the tism are low functioning.
>>2256849It takes 20 seconds to unscrew a resonator and replace it with another, so unless you always need three bands available at a given moment, yes (to that 3-way adapter) and no (to the hustler system in general).
>the angry boomer was at it againDamn dude. It's like you love being angry all the time over nothing.
>>2257030Idk who either of you are (just found this general) but you're both diagnosably autistic to be keeping this up for this long.
>>2257030quit posting that cringy shit
>>2257061It's only cringy because it's a real life experience of you dealing with millenials in the hobby. Go complain on HF about how millenials are ruining the hobby and how your TMI medical issues.
>>2256849Mobile HF antennas of that size are all compromised to about the same extent if they're from a quality brand. They're just so physically small compared to the wavelengths and there's no way around that limitation. I'm working on my mobile HF setup as well. Two tips I can give you:1. Use a NanoVNA or RigExpert to analyze your SWR. You need to tune your antennas because every installation/vehicle is different and has a different de-tuning effect on the antenna.2. Bonding is very important and will make a massive difference. Make sure that you have a solid connection to the frame of your truck. Don't assume that body panels are electrically connected well. I used a rivnut to connect the ground of my antenna to the body panel, and then use rivnuts+copper braid straps to connect the body panel to the frame. To eek out more performance you can also use a strap to electrically connect your hood to the firewall for a larger groundplane.3. Noise is likely an issue. At first the bands were overwhelmed with noise while I had the engine running. I used a copper braid strap to connect the exhaust to the back of the vehicle and it helped. The exhaust is usually hung by insulating rubber and acts like an antenna under your vehicle to re-radiate noise.
>>2256933Yeah I would likely do fine without the threeway adapter, it is pretty cheap though and I like the idea of having more than one band available at a time. And will make the overall mast a tiny bit shorter vertically since it slants the resonators, though I imagine at the cost of some efficiency. As long as it doesn't make the mast too unwieldy.>>2257222Thanks for the advice. I already had a NanoVNA that I used for tuning my VHF/UHF antenna and CB whip; and I've read over K0BG's site a lot and at least have an idea of many of the challenges. Understandably it'll never be efficient, I just like the idea of mobile operation. I probably do need to do some bonding. I do get some sort of spark plug/alternator noise on it (varies with RPM), though still often sit below S1. It is still there though and when accelerating at all you hear the noise come in and weak signals will get lost in it. Only thing that annoys me about the bonding issue is that I bought my truck used and it came with one of those Aluminum Retrax bed covers. Big chunk of metal but doubt it's a good idea to bond aluminum to the steel frame. Wouldn't have bought it myself and it is annoying sometimes, but still nice enough I'd rather not take it off until it breaks,
>>2257236The real problem with the 3 way adapter is the increased weight/mass and wind load on the mast. Stopping/starting rapidly puts a lot of stress on the mount with all that weight at the top of the antenna.
>>2257446Yeah I figured it be worse with wind loading. I'm not against doing some guying to keep it steady and supported. Also not stranger to suspect installations, for better or for worse. Currently running a CR8900A roof mounted with an NMO adapter. Stiff as hell if I ever hit anything with it at any speed it'd probably rip a hole in my roof. Did order a Larsen dual band whip that is actually flexible at the same time as the hustler shit though. The CR8900A is moot since VHF/UHF is a separate output on my new mobile, pointless to have a quad bander on that jack now. If it doesn't work out the adapter was 10 bucks, not a huge deal. Just wanted to try it since I wanted multiband as a "nice to have". Other options for multiband either seemed too compromised for same or maybe more money (tuner and whip), or more than I was willing to spend with additional installation considerations I didn't feel like dealing with (automated screwdriver). If I end up monoband not a big deal since it's still a relatively inexpensive option.
>>2248608Rate my new setup bros. Am I gonna make it?
>>2257657Shit. Maybe I need more Baofengs?
Got a Radioddity DB25-D. It's nice and cheap, comes with the programming cable, and can transmit on the GMRS channels as well as the ham bands. However, CHIRP always comes back that it is not in clone mode. I do not see this at all in the manual. I do not want to use the chink software that comes with it since it is chink software and it is so out of date that it still uses Visual Basic 6. All the threads about it when searching give nothing, and their solutions (e.g. selecting a different radio in the options) have not worked.
>>2257533i'll stop fucking with you and be genuine: what are those, some gmrs radios or something?
>>2257533>>2257793nevermind saw your previous post. i dig the no frills body design.
>>2257797>GT-22Yep it's just a super cheap, small, and programmable FRS radio. I was inspired by another anon to get a bunch for my friends and family for Christmas. The UI is so simple that I *think* my non-technical family members might be able to use them. They would struggle with even a normal FRS radio.
>>2257533If your goal is to get the family up and running, and on getting about 1 mile max, then yes.
>>2257215Says the angry boomer who thinks posting with a female anime character means they are a tranny. Are you still seething your only grandson transitioned?
>>2248608Anyone have any experiences with 14.313?
>>2258450It's the /b of amateur radio - makes the Super Bowl look like a meeting of gentlemen over tea and scones. It's nowhere near as bad as it used to be though, I hear legit qso's there fairly often. I think some of the main dipshits there were corralled by FCC a few years ago.
>>2258459Oh, well that sucks. Are there any sort of fun ways to get into radio?
>>2258450a quick google says I need to start tuning in
>>2258477I know, how do I get onto this shit?>t. ham newfag
>>2258083I listened to an episode of this. I dug it. Does it actually broadcast on shortwave or is it just an internet publication? Found mp3s on endchan
>>2254915Just looked at a few if these courses. It all seems to be something that a ham can use to wave his dick around more in the community. Sorta like:>hey guys, I completed the FEMA courses and got my level 3 cert! See how big my dick is nkw because I wasted a lot of my time reading organizational structure, how to construct a 72 hour pack, common abbreviations used in a radiogram, and how to ground my antenna! So, how big is my dick?
>>2258648>I decree I am the Operations Chief!>I will be the Liaison Officer!!!!>Dibs on Situation-Status Unit Leader!>As Incident Commander, I demand we find a Material Supply Unit Leader!!Hey guys, how is this helping Timmy stuck in the well?
>>2258682>how is an organized leadership structure going to help during a chaotic emergency Gee, no idea.
>>2258648>Everything must be a competition, no matter whatNo difference from any other hobby, or anything else in life for that matter.
>>2258728>hams will save the world!
>>2249725The antenna on those sucks though.The Bf-888 is more practical and you can try multiple antennas.
>>2258753Valid, although I want to keep my family strictly FRS-legal. I figured I would start them off with these small and cheap units, and if they ever want more then they'll get an upgrade to a Wouxun KG-805F or some other premium FRS radio.
I found this in my basement and I just want to listen. As long as I dont press the big orange button the radio jannies wont come after me right
>>2258860it's a CB, you can press the big orange button but be sure there's an antenna connectedhttps://www.radiomuseum.org/r/general_el_citizen_band_transceiver.html
>>2258860and here is the manual :https://www.manualslib.com/manual/1052668/Ge-3-5900.htmlit's a GE 3-5900A
>>2258863Yeah I got the whole kit
>>2258866>>2258865that's a nice piece of vintage nuclear era, from what I understand of CB community in the US you can now listen to mexicans and maybe truckers.
>>2258868I really like pictures on the inside of the case
>>2258869in the 80s someone might actually pull over and help you ?
>>2258871I gess so, my dad got it for my mom pre cellphone dsys
>>2258388I'm 22 you autist. You don't need to be a boomer to hate the turbo-cringe you've been posting here for months
>>2258871> in the 80s someone might actually pull over and > help you ?Yes. I used to commute hour drive late 80's through mid 90's. I pulled over many times to help change a tire for women / old ladies. I can't imagine even trying now for fear they'd claim they were molestered.
>>2258750I say again: why are so many ham radio operators so fat? Jesus Christ, get off the radio, get some exercise, and eat better.
Is ARES a meme?
>>2259018Pretty much. I can see certain uses (tornado, earthquake, or anything that might take down cell towers). For some it's a means to justify the hobby or check in on a net on Sunday nights.t. amateur extra who would die before wearing one of those vests.
>>2258990Why are so many golfers and bass fishermen so fat? It's a hobby that is often cost-prohibitive for millenials and zoomers. Add to that they have to pass tests where there are no participation trophies. Amateur radio is NOT cheap, the same as a set of Ping clubs or tournament bass boats aren't cheap. Plus, many middle aged men get fat. Amateur radio is calorie-free.
>>2258750>the point>>>>>(you)Just curious, are you so used to being disingenuous, that you're incapable of coherent thought?
>>2258990>Why are old ass boomers, most of whom are disabled, fat?Why do you think? You're baseing your view of a hobby off of the portion that have nothing left to do in life but sit on a radio (especially since boomers did a great job making every single generation after them loath them, to the point their own kids hardly see them). At least they're there to get QSOs when doing a SOTA or POTA activation.
>>2259116You are casting pearls among swine. To me the joy of radio began with hearing VOA, or Radio Havana Cuba late at night when AM signals really packed a punch.The fact that I can speak to someone, in real time in England, Italy, Germany, Switzerland, or even Long Beach California on a length of lamp cord strung in my back yard is magical.
>>2258889Whatever you want to say, boomer.
>>2259018tl;dr- it has a lot of applications.When used as a dick measuring contest like most hams do? Yes. But the concepts have a lot of uses. For example, how many people are going to be using those shitty FRS radios during a disaster and they need to pass info along to disaster relief that uses different frequencies? An ARES member most likely has all the radios and is able to take that message and put it in a radio gram to pass it along to other emergency personnel. Another application? Our local ham group helped out the local marathon. Previous years, the aid stations could not communicate between each other because of shitty line of sight causing cell signal issues and using, again, those shitty FRS radios. Hams were placed at each station, and they were able to coordinate with a main person who was able to pass the message along to the person who can get extra water, gels, and electrolyte drinks to the stations when they were running low. One year, instead of running it, I decided to ruck it, as it was a goal of mine to ruck marathon, using my radio gear with a heavy ass battery totaling 40# all together. I volunteered to stay in the back as a sweeper behind the slowest person. I was easily able to communicate where I was and every mile marker I hit. This way, they knew where the slowest person was and was able to work with that information. I can give my pace info and they could calculate and update when the last person was going to finish. This also was able give them info when each aid station could close.
>>2258990>I say againPerhaps better read the replies you have gotten in the past. You have only noticed the fat operators but in reality many are young, fit and normal. Most hams I know have military background, none are fat.
>>2258990It's parallel to gun-obsessed fat boomers in a gun shop babbling about how _____ gun is worthless b/c they can't trust their life on it b/c of ______ bullshit conclusion.Meanwhile they're incapable of trusting their life on themselves to avoid cancer, heart disease, or diabetes.Same person, different hobby.
>>2259187>Perhaps better read the replies you have gotten in the past. You have only noticed the fat operators but in reality many are young, fit and normal. Most hams I know have military background, none are fat.
>>2259187Stop replying to the resident troll. His mother won't let him get a license, so he comes here to take out his insolent rage on people. Usually he accuses people of being old, boomers, and/or fat, you know, because that's the lowest hanging fruit for someone who is too stupid or lazy to get a tech ticket. Sometime this will lead to a tirade about the government needing your address and 'muh freedoms,' however that may be other anti-government nuts piling on since a lot of larping /k/ tourists end up here.
>>2259232Why post your aspirational self-portrait? You'll make it one day.
>>2259256Why do you seethe so much? Maybe one day you'll learn to stop being so cranky.
>>2259278>Why do you seethe so much? Maybe one day you'll learn to stop being so cranky.
>>2258990>Jesus Christ, get off the radio, get some exercise, and eat better.SOTA, POTA, etc. thenI regularly go on a hike with a friend and we bring a radio, we are in small mountains and being on top of a hill is wonderfulBut most of HAMs are 65 yo and over so they don't do physical stuff like this anymore
Redpill me on the FT-818. I would like a reasonably compact and self-contained setup for primarily HF with VHF/UHF as a bonus.How much of an issue is the lack of a built in ATU?
>>2259373At the power it delivers, ATU isn't a problem, buy a nanoVNA and you are good to goyou can get a small amplifier that will deliver 20-25 W on aliexpress, worth the price.My mobile setup is :- FT-818ND- mini PA50- chink copy of the PAC12 (I bought too extendable rods)
>>2259380With the 5m long rod of course.on 20m you don't need the inductance, I got it for 40m, I will not go below that in frequency.Also I have 2 radials
>>2259380>20-25 wattsWhy bother? Deal with the barefoot rig or buy one with more power. You can find a used 897 or even a 857D or 100D instead of carting around a bunch of jumpers and extra wires.>miniPA50That's 45 watts, which at least isn't completely pointless.>>2259373Elecraft T1 or LDG Z817
>>2259388>Why bother?It's enough for me, other rigs are bigger and weight more and require more power at Rx. I also use that amplifier with a 20m very light Tx kit : Iler-20, about the same dimensions as the FT-818 but way lighter.
>>2259373It's an alright rig. Not a lot of power at 6W, but it doesn't need much for a battery. Fairly easy to use, and hooks up to a computer fairly easy with a SignaLink. Currently I've been using mine as a basestation for VHF (way to much interference in my office for HF), and with 6w I cleanly hit repeaters that are 15-25 miles away using a GP VHF/UHF antenna. As far as no ATU goes, I got a LDG Z817, but I hardly ever use it, instead just using a tuned antenna, like >>2259380 mentions. There's some neat accessories for it, and a fair bit of frames to chose from. My current mobile setup is:>MARS molded FT-818ND>SignaLink>3Ah Bioenno battery>Uni-815 paddles>LDG Z817 (often left behind)>MFJ-281 speaker (not nessasary, just nice when stationary)For antennas (picked based on what I plan to do):>LDG 1:1 BalUn w/ 20m tuned dipole 18ga speakerwire>Arrow II yagi (for satellites) >MFJ 6m whip with mag mount>Diamond RH77CA (also use on VX-6R)>>2259380I need to pick up an amp at some point. Might get that miniPA50 so I can get more juice out of my 818.
>>2259254>tirade about the government needing your addressThat person is me. I have no problem with the FCC having my address. The problem I have is them publicly posting my address since it gets abused. I still get junk mail from the local groups asking to join. I even got some from the ARRL including one which was a ballot to select their next CEO or something, along with some shop trying to sell me gear. I'm not a ARRL member, so why should I receive that? Add in: https://haminfo.tetranz.com/mapIf you don't see why this is a problem, you are most likely part of the problem.
>>2259529Not him, but that's why I have a PO Box. I haven't gotten anything from clubs though, and everything I get from the ARRL, I only started getting after making an account. What really chapped my ass, while on the subject, was when I ordered some stamp mounts off Amazon for some Euro stamps, and now I get weekly junk mail from Mystic Stamps.
>>2259529Listen up. Do you have a credit card? Book a cruise with it. See how many cruise brochures (expensive ones) you start getting in the mail. You have internet service - how often do they bug you to get TV or cell service?Have you TRIED looking up an address from a call sign? It's easy on qrz.com IF you have an account. If you go to the FCC website you will be lucky to find where to search it's so outdated. Don't post your call here, the same as you wouldn't post your DL#.
>>2259529>If you don't see why this is a problem, you are most likely part of the problem.It's real life. Don't get licensed if you don't like it. I formed a LLC for a small business I own, through the state I live in. I get AMEX approval letters, website design letters, Yellow Pages letters. If you want to remain discreet stick to CB.
>>2259562One of the biggest mistakes I ever made was using my real email and phone # to register a domain name. I get calls and emails from street shitters all the goddamn time now.
>>2259556I don't use a credit card. Only a moron uses them. Why would I go on a cruise? I like my bike trips. And no, I don't travel via credit card.>>2259562Just because it's normal and "real life" for any service does not make it right. Rioting and looting is the norm for protesting, does that mean theft is right? You've been conditioned to believe receiving unsolicited mail is okay. It isn't.
>>2259617We get it. You live in a buried shipping container stroking your guns. I'd assume you only leave to bury your gold and silver in random places and move your bug out bag at the designated time interval.
>>2259677Jokes on you: you forgot that I also leave my bunker to buy more supplies and bury it in a cache.
>>2259018ARES is a half assed version of RACES.RACES makes you a member of Civil Defense/FEMA.

Hello hamgen, first time ever posting here.I don't know anything about ham radios or amateur radio or CV radio or the proper terminology, but I've been thinking of getting my canadian amateur radio operator license.Came here to ask where I should start, I have a PDF for a 300 page manual that others have said should be sufficient to pass the test, look up Emcomm Ham Radio PDF and it should be the first thing.Problem is its from 2009 so I'm not sure if it would still be accurate or not, apologies if thats a stupid thing to worry about since I assume MOST things should stay the same independantly.Besides that manual, which links should I read through first out of the ones posted here? And how big are the differences between canadian and american amateur radio?
>>2259943Also any recommendations on a beginner setup for cheap before I start reading 4000 pages of information and build my own out of stuff from the garage? (I plan on doing this anyway but would like to have a basic setup to test and fuck with before I embark on that journey)
>>2259943Contact your nearest ham club and ask them for help on the bureaucratic process. It will save you a ton of reading and you'll find it much easier that way.Most of the time they're pretty helpful too.
>>2259949Yeah I probably should just I don't wanna look like the one retard who doesn't know jack shit hence why I'm asking stupid questions here and not in person.Also is it really true they can hit you with huge fines if you yell stupid shit in the wrong places? Like how do they track your location/find out who you are based on your transmission? Proabably a very stupid question since if its anything military they most definetly have equipment thats advanced enough and capable enough to detect that, but I mean just like with random people in general.
>>2259950>I don't wanna look like the one retard who doesn't know jack shiteverybody was a beginner, the ham clubs, same as other clubs, are also here to inform, teach
>oh look the troll is at it again
>>2259957there's a troll in these threads?what does he do?
>>2259146Yeah cool faggot I can do the exact same thing right now on 4chan
>>2259992coming from someone who's never done this shit himself, I'd assume its because setting everything up requires actual effort so its a lot more fun and rewarding than just going on le ebin 4chin and calling someone a faggot
Ham radio is a shit hobby that deserves to die
>>2259999sitting on your fat ass and insulting shit hobbies is a shit hobby that deserves to die
Anyone uBitx qrp here? The kit is nice enough for the price. Receive is fine. The Mic blows. Testing with friends on 10m (local) - SSB phone can hardly be heard, if at all. Keep in mind friend is close enough that cans and a string would work.Thing is - CW with the mic is LOUD AND CLEAR. Kit comes with a Baofeng mic. Any ideas?
>>2259999>t. Neckbeard on a Mongolian basket weaving image boardWow, so inspiring.
>>2259931I haven't been able to get it to work on CHIRP. Since no one answered here and all the workarounds did not work, I went ahead and got out my old Win7 netbook, installed the chink software to program it. Even then, it took a lot just to get it to work. At least now I can program it, but it's just shit. It reminds me so much of the old days of being a PC Tech when each company developed their own proprietary standards. Ham radio needs to get with the times. As a bonus, it works on the GMRS channels so now I get to use it as my GMRS base station as well. I just wish I had more time to play on it.
>>2260137Stop expecting the world from chink trash
>>2260137A problem with the stock software is the Chinois don't have the same mentality we have with what should be on the left and right which takes more time.>>2260139This is a good radio. The sensitivity and selectivity are both good.
>>2259948What are your ham goals? Test shouldn't be hard, it's more or less the same test for first world countries.
forget amateurwhat does it take to get a legit radio station going
>>2260798I guess you could join MARS, and buy only Harris and Motorola radios.
>>2259677>bug out bagNow this brings up some questions that I wonder if /HAM/ can answer. How do we set up a BOB with our emcomm gear? Do we use a HT or go with a smaller mobile radio? If smaller mobile, what about batteries? What about the antenna? Make a wire dipole and weave it into somewhere on the bag? Or just get a standard whip antenna?
>>2260798Lots of money, as people buy up the rights to a frequency on both the FM and AM bands quickly when they come up for auction.
>>2260607For what I have tested so far, it is great at transmitting and receiving even for just a chink radio. There is a repeater quite a bit a ways away that my 50w alinco won't hit, yet this radio hits and receives it just fine at 20w. And I love that I'm able to transmit on GMRS with it. I need to program MURS on it as well. However, it's buggy. Anytime I turn it off, I have to set the CTCSS tones multiple times before it saves. The buttons will sometimes change their function (e.g. F5 can confirm in a menu, but 10 minutes later it is changing the thing from Channel to VFO mode and reverse. I haven't tested the APRS function on it yet.

Holy cow, CW is on fire. What competition is this weekend?
>>2261225>imagine thinking this is chad behavior
>>2261052I like that this has both a narrow FM transmit capability as well as a true narrow receive.I can understand people with older radios and such who only have wide receive audio not liking narrow band, but if 2 or more people have it you can get out better.I put narrow transmit on a repeater of mine and it got rid of some dead spots.

what should i listen to you guys on
its been a few years since i used digital modes. recently i went to the psk part of the bands and found all the signals time synchronised and frequency offset. when i used to do psk it was simplex and everyones conversations ran at random pace, often at the speed at which one could type. is psk now fully automated? did i miss a memo during the last 5 years?
>>2261892you've seen FT8 and similar mode, like on 7075, 14075
>>2261894thanks for the heads up.maybe just my part of the world but there are only these signals all day. no psk31, mfsk, rtty, feldhell.pity because i used to like those modes (esp feldhell and rtty)
>>2261898There is some RTTY and PSK31, but FT8 and similar JT modes are automated and are emitted continuouslyThis week end there's a LOT of CW maybe a contest so people might have switched to CW instead of digital modesI don't know if this is actually used :https://sumterdigitalgroup.com/digital-modes/frequencies/Here is some kind of a list of where to find whaton 20m and 40m I just go below and above the FT8 around 7075 and 14075
>>2261892>>2261898Yeah, everyone is about the contacts in the logbook now. The nice thing about psk and rtty was the fact it was more like a traditional phone contact where you could ragchew or just make a quick contact. Now, people run high power using weak signal modes and fill up their logs. Kind of like beating a video game with all the cheats turned on, I don't consider this an accomplishment. Don't get me wrong, if people want to do it, great, however I just wish people didn't totally abandon the other modes for the automated one minute qso that is the wsjt modes.
yeah i dont feel any achievement in letting my computer run my radio without my interaction. it was bad enough with constant macro qso's on psk. contests can go eat a bag of dicks too.the only time i have ever let my computer run the radio was 15 years ago when i lived an hours drive from the nearest internet and because of mechanical exchange system i couldnt even dialup. i used pskmail for basic email which really got me out of a few tight spots. qudos to the few people still running those nodes.
question here from a /g/-man. not exactly amateur radio, but i figured its right up your guys' alleyi have an android phone with an FM circuiti want to listen to HD radio (digital FM in the US)can this be accomplished by software - using the FM to pick up the digital signal, then using the computer to decode whatever codec HD radio usesor is extra hardware necessary to even pick up the signal
If anyone missed it, an HackRF alternatives is in the works
>>2261975WTF are you talking about, anon? There's no such thing as HD or digital radio unless you're talking about Sirius or something, in which case I'm sure they have an app but they use COFDM-DQPSK and not FM.
>>2262038>There's no such thing as HD or digital radioThere is, it's called DAB or something like that
>>2262038>>2262039the official standard in the USA is called HD Radio>https://en.wikipedia.org/wiki/HD_Radio
>>2262045>HD Radio(HDR)is atrademarkedterm for anin-band on-channel(IBOC)digital radioThat's like saying what I listen to is Icom Frequency.
CANT HEAR ANYTHING
>>224860810m. Start paying attention, even you techs. As 10m begins to open, nets are coming around. Many are local nets that have always been there. Tune 28400-281500. Throw out a cq at the top of the hour. Worked Oregon from Florida today.
>>2262312I meant 28.400 - 28.450
>>2262011About time. HackRF is overpriced crap.
>>2262324*tries all DTMF tones ten times*
Any nets in Asia? Can anyone reach me?
>>2262324You are kerchunking at most 3-4 people. If they don't hear a voice they ignore. The repeater will tell the time, and a callsign. Why frigging bother?
>>2262202blame the fcc
>>2261938Not many people want to chew the rag on digital modes anymore. Although my absolute favorite part of ft8 is that I no longer have to read any <BRAG> macros.
I don't know that much about radio, but I just got my Drake 2B shortwave receiver running again (it had a blown output transformer). Last time it ran was 5-6 years ago. I could swear that back then, there was more to listen to. I remember picking up all kinds of stuff with just a short random wire antenna. Now I hear almost nothing. I have it working on the 80, 40, 20, 15, and one of the 10 meter bands. The only thing I've heard is a little bit of CW on 80 and 40 meters, and some very faint shortwave broadcast on 40. I did hear a lot of CW on friday, guess I was hearing >>2261209. I put up a 30' long dipole antenna indoors, but that didn't seem to improve performance over an 8' long random wire. it's also picking up some kind of interference with peaks about every 30KHz on every band.
Building a crystal radio receiver atm. What's another diy must build radio? Thinking maybe an ignition coil spark-gap radio, but not sure what I want to do for a transceiver.
>>2262202if it makes you feel better the technical name is NRSC‑5
>>2262459Conditions have been shit recently. Also, you need to get your antenna outdoors. Your reception will improve vastly and may reduce that interference you're hearing.
>>2262483>ignition coil spark-gap radioThese aren't legal to transmit with.
>>2262536I've only seen plans for spark gap receivers. I'd build a transmitters because fuck the FCC, but I can't CW for shit atm. Just building to build.
>>2262543Thing with the spark gap transmitters is they make so much rf noise/interference that it will attract phone/cable/power companies looking for faults. It's like wideband jamming. Most of the time the same shit is caused by broken utility wires. The FCC fines them hundreds of thousands per day for faults like this, so they're quick to locate and fix them.
Is there a book I can use to get into ham radio? I want to start with electromagnetism and actually be able to grasp how things work.
How do I program the BF-F8HP from CHIRP?The software can read my old UV-5R+ just fine, but when I try to read from the BF-F8HP I get pic related. The radio itself also seems to bug out while it's plugged in.I'm not doing anything different for either one, is there an extra step needed or what?
>>2262720Like I said, a transmitter isn't the plan for the spark gap, I would however like to build a transmitter of some kind to use alongside it.
>>2262762>Is there a book I can use to get into ham radio? Ihttps://f6glz.files.wordpress.com/2013/09/csts_book.pdf
>>2262534>you need to get your antenna outdoorsthat's too bad, I can't do that here. Years ago I pulled in a lot of stuff with a sketchy indoor antenna. Is that all due to sunspot activity being higher in 2014-2015 than it is today? Or is there just less on the air now than there was back then? or both? It's disappointing, I love this radio and wish I could make it sing.
>>2263006You could try a passive loop antenna (or one of the variations of a loop antenna). From what I recall they were popular indoor SW/AM antennas, back when nearly everyone had a SW radio.
>>2263032I was just reading up on these, actually. It's something I'm going to try. i'm also going to see what other crystals I can collect for the 2B, i'm most interested in receiving shortwave broadcast bands. Any suggestions about what bands would be the most interesting to listen on?
>>2262966Thank you! From a quick glance, that looks amazing. Gonna print it
>>2263006It's a bit of both. VOA and BBC, Cuba, etc. still there though. A lot of religious broadcasting now - it was always there too but seems everywhere on SW now.
>>2263401The religious shows are so much on there that they even pirate broadcast over other religious stations.
>>2248608ALL you new technicians and generals - this is a great Idea I saw posted on qrz. At the top of each hour, call CQ on 28.400 - 28.420CB bands a rocking, hams paying no attention to 10m. Get in the habit.
>>2263401>>2263406why is there so much religious shit on shortwave? I know they just rent the transmitter, but where is the money coming from? donations? it doesn't really add up to me
>>2263998Athiests on suicide watch knowing they have the word of God penetrating them every day and night

We'll give you a cool mug in exchange showing you like to have unused spaces that you will never use that have scientific applications!
>>2264322Yes. And? As >>2264323 said: they have their place. I have 6 in a faraday cage that I check at least once a month that are ready to go and give out if SHTF.
>>2264332>$100 mug>Thx for your $60/yr
>>2264334It's a special mug! We'll even put it up on the annual auction next year so someone will pay $300 for it like the $5 sling bag and the $10 lunch box!
>>2264335Cool it with the anti-semitism!>That'll be $100 for your FT8 certificate
>>2264337I would not be surprised if ARRL had already thought about doing that.
>>2264339That was damn close to my DXCC cert cost>$5.50>$0.12 x 100>$12>$5$34.50And you have to be a member in the US to get a cert, so that'll be another $65.
>>2264333>'tard preppers relying on cheap chink clone of a clone>Muh faraday cage will save me
>>2264372>'tard preppersAsk those 'tard preppers in Texas how comfortable they were when the grid was down during last winter, and how they were able to communicate and help people out via coordination. Then ask all those dead people who froze to death or were dumb enough to lit charcoal in an enclosed space how comfortable they were. Oh wait, they're dead. My bad.Stop relying on the media and ARRL to tell you what to think.
>>2264394>Even bigger 'tards died, me smart. survived 2 days of chilly willy weather in my own home
>he's seething again
>>2264394Agreed. I treat hurricanes and storms like military readiness exercises. Proper prep includes clothing and sleeping gear (bag, underquilt if using hammock etc) such that you will be comfy and burn little energy even with no heating. Heating is mostly to preserve water pipes so that can be turned way down to extend your backup fuel supply.
>>2264452>military readiness exercisego larp on /k/
>>2264152You could get a brass plate, some files, and a drill and make one. Could maybe get all that off aliexpress for $4.
>>2264597If he knows someone that does metal casting, they could take a 3d print, put it in a sand mold, and pour molten brass into it.
Has 80M DX been a dud for you all too lately?

>>2264597>>2264600My point is I could, and did, go on the fleabay and picked up 5-8 brass knuckles for less than $5.And they arrived in a week or two.Now they're banned, anything else similar is $20. I have a 3D printer. I could do casting. But not for sub $5 for a dumb gimmick.
>>226502610m was open for much of the afternoon. You faggots are discussing brass knuckles. Why don't you guys just meet up, and go live on r9k? /k wouldn't have you. Brass knuckles, Jesus.

How the fuck do you figure out what timeslot a talk group belongs in in DMR?Many of the websites pertaining to what network an amateur DMR repeater belongs to are half assed in that regard.
