>>1998647Never did myself the favour until summer last year and got me a CB radio for the car. Ham radio vs. CB is like your boomer parents' facebook against /pol/.
>>1998661I’ve heard stuff on 75 meters that’d be just about the same as CB. Usually later at night so you know some alcohol is probably involved.
>>1998842There are exceptions. European hams are pretty stuck up, it's just one or two ham nets every night that seem to really have fun.
I'm getting trained as a SKYWARN spotter. What frequencies does the NWS monitor for reports? Do they have special frequencies or do they use the local ARES repeater?
Radio newb looking for an inexpensive (Under $100) HT. I'm a volunteer firefighter and want a backup radio for personal use; it needs to be able to RX/TX 150-155 mHz for my district. 1.Is there a good resource for technical information? I found this guys website but most reviews are at least 5 years old. https://hamgear.wordpress.com/2015/06/18/review-pofung-baofeng-uv-82hp/2. From my reading, the Baofeng and most chinese radios use a chip for front-end filtering, but some like the Wouxun are superhet radios. Is a superhet HT worth the extra price? Which of the software-front-end (don't know the correct term) HTs are the best?
>>1999164Look for a deal on a Yaesu FT-65, or the FT-4 if you want something small. If you're lucky your department might have access to the programming gear for Motorola radios, they tend to be great and go cheap used on eBay.
>>1999164None of those radios shown are intrinsically safe. You would think a real firefighter would be concerned with that, no?Also do you have approval from the license holder to put a personal radio on their system? How will you register the ID for emergency button and man down?The acceptable choices for public safety radios come from Harris, Motorola, Kenwood, EFJohnson, Tait,etc. Chinkshit will get someone killed.
>>1998968It’s a mixed bag here in the states. Anything from the stuck up legalistic prick to the ota shitposters.
>>1999178We could borrow some of your shitposters. Best you can get here are French freebanders below 80m.
>>1999171I think he wants a backup radio for personal use, as in for completely off-duty things. You make a point, but perhaps missing his.
>>1999219Nah, he is likely just a wacker. Not actually on a FD, or issued a Minitor pager that cant TX. Many such cases.
Am I allowed to host a show about jews and niggers on ham radio? As long as I don't say kike or coon?
Made my first QSO yesterday. Was able to hit a VHF repeater about 11 miles away in the suburbs with my UV-82 and a 42" Abbree antenna. Got to talk for half an hour to a pretty chill guy from one of the local clubs that seemed pretty excited to hear someone new.
>>1999347Unfortunately, broadcasting is illegal on amateur radio.
>>1999167Thanks anon, I will look at those Yaesu models. Our dept issues Motorolas but I don't know if they have programming equipment. Will need to ask the comms guy.>>1999171>>1999251As I posted, I want a backup radio, not a duty radio. I'm in a rural county and want to be able to listen to county traffic and keep a radio in my POV. We also run medical calls, as you're no doubt aware. At no point did I state I'd be using the radio on the fire ground. Mostly I want my own radio to play with, and this is a good excuse. As for approval, I've already asked. I expect this process was much less complicated than it would be in a city department. We do have a few old Minitor pagers kicking around, but most everyone has a Swissphone now. They can't TX either.
>>1998658YSF room when HF net when
>>1998658I need to pass the torch on to some young buck who wants to keep posting our leader in these theads?
>>1999384get a uhf1 vhf apx7000 with fpp -- thats what i have.
>>1999384>I'm in a rural county and want to be able to listen to county traffic and keep a radio in my POVGet a scanner then. Don't think for a moment that someone telling you that it's OK is enough. The moment a higher up (on the PS chain) finds out you've been using a personal radio to Tx, you're done.
>>1999577Why don't you just stop posting your troll image instead.
>>1999730You have no understanding of my situation, or who I have and haven't' spoken with. I do appreciate your concern though.
>>1999164For a hobby that encourages self-directed learning and DIY tinkering, there's a real lack of autism-fueled technical information on these radios. Like what chipset each radio model uses, which firmware versions they run, what the differences in performance are between each, etc.
>>1999577Post the original version at least.
>>1999764>Rules don't apply to me, I'm special!>>1999767It's all the same shit with different paint
>>1999767Pretty much every analog Baofeng uses an RDA1846
>>1999786>>1999787Baofeng indicates there's a difference, even if it's not a different chipset. This guy seems to think there's a difference in performance between the 1st and 2nd gen PCB:https://hamgear.wordpress.com/2014/12/14/review-baofeng-gt-3-mark-ii/Anyway it's quickly becoming clear that I need to look at more expensive radios if I want something good. I'm just surprised there isn't more technical info given the popularity of the Baofengs.
I am a new guy and finally bought a cheap baofeng and usb programming cable. Starting off planning on just listening in and learning how to program it. What has always made me nervous about getting the license is having you address publicly available online. I know you can use a PO BOX, but that is not an option for me. Anything weird ever happen to you guys with your address out there?
>>2000199Are you in witness protection or something? Your "address is out there" already in 100 other public databases. Be shitty to people on the air and maybe you might get a knock on your door from someone. Be a normal human and nothing to worry about. What you DONT want to do is post your call on a place like 4chan. That is just asking for problems. I keep my ham and internet identities completely separate.

Please help me with my silly entry level questions. I live just outside Nashville and all my service went down on Christmas day during the attack. I'm making ham radio a priority now for comms.I am interested in the Yaesu VX-6R. I have some basic questions though- How easy is it to program a lockout for the transmission button, so I don't have to worry about sending illegal transmissions before I've gotten my technician's license - Can I listen to local FM broadcasts if I need to be able to? Some have this feature but I can't figure out if this one does-In case of emergency could I hook the antenna input up to a large rooftop antenna (built for this purpose) for a large boost in receiving capabilities?Thanks for your help
>>2000663Read the manual.https://www.yaesu.com/downloadFile.cfm?FileID=7039&FileCatID=151&FileName=VX%2D6R%5FE%5FOM%5FUSA%5FEXP%5FEU%5FENG%5FEH021M204%5F20111019.pdfProgram in an "out of band" frequency for TX and the station you want on RX.VX-6R or VX-6R/E? The VX-6R/E manual says it can listen to FM. For the purpose of recieving FM broadcast radio? Sure you can.For amateur radio? Sure you can.Heck, you might even prefer using it that way.Study and do the test.Open the following "magnet link" in a torrent client like "qbittorent" or "transmission":magnet:?xt=urn:btih:ecc3aa75d8add578894bc32a342071701605fba3&dn=ARRL%20Amateur%20Radio%20Technician%20Class%20Training%20Course%20%20H.264.mp4&tr=udp%3a%2f%2ftracker.coppersurfer.tk%3a6969%2fannounce&tr=udp%3a%2f%2f9.rarbg.me%3a2850%2fannounce&tr=udp%3a%2f%2f9.rarbg.to%3a2920%2fannounce&tr=udp%3a%2f%2ftracker.opentrackr.org%3a1337&tr=udp%3a%2f%2ftracker.leechers-paradise.org%3a6969%2fannounceIt will download a video that will get you up to speed on the terminology, how radio waves work, how to operate your radio, making antennas, etc. etc.Best of luck.
>>2000686Thank you so much, I'll try to do it before the FCC jacks the license up
>>20006631. I'm sure it's in the menu. Or don't push the button. Nobody is that anal IMO2. Pic related3. Absolutely.Look into Chirp for the programming. It's just a data cable and Excel file.And 90% of your focus should be on the exam - study for the General. You'll get a chance to take it at the same for free
I started reading the ARRL tech book and it starts off good with the introduction, but then all of a sudden gets extremely complicated and doesn't hold your hand much as expected from the intro.I dropped it, and so far have been working through watching Ham Radio 2.0's 3part 2hr long each Tech classeshttps://www.youtube.com/watch?v=0wwnOPaF1qIThese are so much better, however being new I still get confused on some things of course and also forget stuff. I seem to have trouble remembering and understanding differences between bands, frequencies, and whats used for what. For example, if?you asked me difference between 2meter 10meter I wouldn't be able to tell you.I understand frequencies and VHF UHF and HF for the most part, bandwidth I'm a little confused on how it plays a role. I am confused on frequencies in correlation to the bands though, like 2meter has these frequencies, 10 has these, etc.Does anyone have any suggestions on learning this stuff? Preferably a video or something easy to understand? Also the other thing being electrical components, I have a basic understanding of electrical components, however when going through a ham practice exam, I don't know questions about how they're made and stuff so I need to learn more. Does anyone have a video on this, but is more aimed towards HAM vs just a video on electrical components in general? So I'm not learning way more than I need.I wanna learn enough to get my exam, start using things and as I go dip my feet into electronics in general more. But not too much right now or I overload my brain lol.
>>2000957Yes.I linked to a video here:>>2000686It answers all of your questions.Also, now you are starting to learn the words to be able to formulate questions! Right on. This is the major hurdle most face. Now you know enough to send yourself down a rabbit hole!Google "difference between 2meter 10meter " and you get all sorts of crappy answers to investigate!Or just watch the video ^_^Take a practice exham and just google every question you get wrong.You will then remember it, and understand why the answer is a certain way.
>>2000987Thanks, is that the full course or only one video out of multiple?If the latter, do you have the full set torrent?Also what online course is this from?
>>2001111Checked! Nice quads.ARRL Amateur Radio Technician Class Training Course.It's all as one video. It's 6.5 hours long.
>>2001173BasedAlso thanks anon
>>2000957>Is mayonnaise an instrument?
>>2000957Freq - band correlation is 300/band = freq30M = 10 mHz.40M = 300/40 or 7mHz.That's just memorization from frequent usage.The differences. Remember AM and FM radio in your car?Their characteristics? AM you can hear a station 60 miles away all day any day, and on a good night, 200 miles away? Whereas an FM station you might lose going under a bridge a few miles away?Well, they're on the far end of each spectrum. AM radio is roughly 1mHz. FM radio is roughly 100mHz aka 160M and 2M.Everything in between gets progressively more like AM or FM based on the freq. Simple as that.
>>2000957And I'll get shit on, but the electronics component is a little dated.It's good to know the theory and what each electronic piece does, but don't expect to get a modern radio and ever work on it.Yes, transistors were a marvelous invention 100 years ago.Impedance is vital to antennas.The pre-amp to mixer to something to something circuitry could be done away with.
>>2001489Clear channel AM stations can be heard much farther than that at night. Those are the ones the FCC allows to crank out 50KW 24/7. Hell, some come pretty close to the 200 mile range during the day. Case in point: I rode across the state of Tennessee last fall and was listening to WSM in Nashville from Knoxville to Memphis.The top-tier FM stations can cover large swaths of land themselves if they’re up on a really high tower and pushing 100KW. Can easily be heard within a 50 mile radius of the transmitter.To anyone curious to learn more about radio propagation, Wikipedia is a good start. There’s so many factors at play that it can’t always be explained in a simple manner.
Hey y'all, I fucked up my rtlsdr dongle. I had them working real well until I changed some sort of configurations in a /diy/ I was trying to do which essentially would scan trunked systems and aircraft transponders at the same time. The problem is that I modified some sort of essential configration to the dongle, and I was barred out so I don't remember what the hell I did so I can change it back. So my question is, does anyone know if it's possible just to wipe the dongle and reinstall the drivers and everything, or is that not really a possibility?
>>2001489Make sure you don't confuse him with millihertz when you mean megahertz
>>2001506Ehh, I was trying to relate to the entry student's current experience.I can hear 200-500mile away AM stations during the day and easily hear halfway across the world at night - but certainly not with my factory car antenna.Thought it was a good, practical example of what to expect at each range of the bands as I took my big, stinky morning shit.
>>2001632Fair enough. And I guess that I was further expounding upon what you had posted. I’m just super autistic don’t mind me.But seriously, to anyone who’s really interested, Wikipedia can explain this shit way better than anyone can on a Mongolian throat-singing board.
What are some easy projects I can use with a raspberry pi 3?
>>2001911I use a Pi 4 to run Fldigi as well as rig control. Basically, it’s my station’s computer. Set up a VNC server on it and remote into it from anywhere in the house. It’s great, I don’t know why more hams don’t do this.
>>2001920Can I make an am radio with it
>>2001927If you get an SDR dongle, a suitable antenna, and put some SDR software on it yes.
>>2001684You're not wrongt.dude who takes stinky shitsI found this to be a great primer>https://www.hamuniverse.com/hfbands.html
>>2001944Will an SDR dongle work on a micro SD card?
>>2002073Not sure what you mean. I myself haven’t set up an SDR on a Pi but I know others have.
>>2000686That video breaks around 12min for a min or soGot a better copy?
Whats the next step up from a uv5r?Both in handheld and desktop+antenna?Preferably under $200 (factoring in price for antenna for desktop)
Can you guys get SiriusXM?
>>2002122>Both in handheld and desktop+antenna?$200 each?I wouldn't mess with a ht. If there's a hamfest, you can pick up a name brand mobile tx. Otherwise take your pick of QYT or TYT or Anytone
>>2002120It fixes at about 15 if I remember correctly. Rest of the video works fine.It's the best copy floating around on the net
Don't want to get my ham radio license anymore. Can I still enjoy the hobby of just listening?
>>2002851If you stopped, perhaps you'd hear a signal or two over your whining.
>>2002851Yes. But other than the cost, why wouldn’t you wanna put your own signals on the air?
does anybody hang out on CB anymore or is it all just truckers
>>2002890>>2002851Building transmitters can be cheap and cheerful.http://www.sparkbangbuzz.com/easy-ten/easy-ten.htmLook at how simple that is too build?I bet if you put a LDR in series or parallel with the 1K or parallel with crystal, or parallel with antenna capacitor, you could transmit signals with morse code controlled by your computer:https://morsecode.world/international/translator.html
>>2002906So there's still a hobby out there for building and listening? I don't want my license because I don't want my address and name in the FCC database openly
>>2002910Sure. Check this out:https://anarchy.translocal.jp/radio/micro/howtosimplestTX.htmlI highly recommend an RTL-SDR or similar for tuning (figure out what frequency it's on). Although it can be built and tested with a FM receiver.Without an antenna it transmits just to the room. With a meter of wire on the ground plane, and a meter of wire on the positive, it reaches 3 blocks with just a 2n3904 as the transistor!People still do Short Wave Listening.https://en.wikipedia.org/wiki/Shortwave_listening
>>2002851Check out websdr.org
I just found a numbers station in spanish at 45.420 wtfit went "pshaaaah" ~three times every ten seconds, read 5 numbers in spanish, repeated, then went "eeeeeeeeeee" then "pshaaaaah" ~two more timesthen I found a time station at 18.800 but that's not the same. I need a better antenna fuck
>>2002906>Look at how simple that is too build?And what are the harmonics like?
>>2003020To be honest, the harmonics are somewhat high with that one.I'll see about digging up a better crystal oscillator. Some don't need filtering.
>>2002905It’s still hanging on in the south. There’s usually at least one local group out there.>>2002910Your name and address is not private information.
>>2003022I think also transmitters using a DDS are free from harmonics, at least within the HF band. Using a 120 MHz sampling rate would mean very high harmonics which would be unlikely to be effectively radiated from a HF antenna.
Need some help troubleshooting/wrapping my head around a base-loaded magnetic-mount CB antenna. I've been trying to look up info online, but all I'm getting is either shopping results, or non-related shit due to keywords.I'm trying to put together a mobile cb setup, out of the leftovers from my father's stash of parts. I've got this old as fuck base-loaded antenna on a magnetic-mount that's in poor shape and needed repair (coax mostly detached from plug, Coil detached from pl socket, threads for socket on base fucking trashed)). I fixed it up, but I'm not sure if I actually -fixed- it, due to not understanding how this type of antenna works; Like how the antenna coil appears to be meant to connect to the shield of it's pl-259 connector, creating a "short" across the antenna and ground connections. After repairing and reassembling the antenna, I did a continuity test with my DMM, and sure enough, there was a clean, zero-resistance reading from the tip of the center pin on the coax' pl-259, and it's shield. I could put my test leads anywhere on the antenna and get a connection.Yesterday I set everything up in my van, went down to the beach so I'd have plenty of open space, hooked up one of the old SWR meters I found, and began calibrating. After I got the SWR in usable shape (1.4 on CH01 and CH40), I started listening and transmitting. Heard plenty of traffic, and made contact with some guy a few miles out, said my copy was good and clear.After that I turned the van on, and got a fuckload of engine/electrical interference, but that I can square away later.I guess what I'm asking is: In retard terms, what are the basics of a base-loaded magnetic-mount antenna? What are indicators of "it fucking works, retard", or "it's fucking busted, retard"? The internet seems to go from "buy here!" to "here's every antenna design known to man" to "intricate discussion on advanced antenna design and signal propagation for NASA".Plz halp.
>>2003328Your antenna is fine. Don't try to "fix" it beyond what you have done (unless you're replacing the coax or a connector). If it were busted your swr would be above 10 and no one would hear you.
>>2003328You have a capacitative coupling to your car roof which acts as a counterpoise. Would you shortcircuit the base with the roof, the roof would add to the antenna capacity.I did experiments with a mag-mount, trying to make it double as a home antenna to take my CB inside. Took me a while and it's still "it fucking works" - but I added a contact to the whip's base (above the baseplate) and ran a wire to a tin can on which the magnetic base sat. When the wire was about the length of the whip and ran ca. 135° away from the antenna it started acting as a counterpoise and I got the SWR down to 1.5.I could make contacts from home using the CB. For car mount, I just remove the tin can and cable again.I just read this on qrz.com before:https://forums.qrz.com/index.php?threads/dr-ulrich-rohde-electrically-short-antennas.740851/
>>2003338>Don't try to "fix" it beyond what you have done (unless you're replacing the coax or a connector)Gotcha. This thing's in pretty rough shape, physically speaking, and the cable could stand to be shortened, so there may be some more work in the future, but otherwise it'll stay as-is.>>2003339>text about adapting mag-mount for home useFunny enough, I did something similar before loading the whole thing into the van. I had the CB and antenna in a second-floor bedroom, hooked up to an old desktop CB/ham power supply. I didn't dare transmit, because I didn't have the jumper cable needed to tie the SWR meter in for calibration, so I just listened. I had the antenna sitting on some metal window screen, as a redneck ground plain, and was able to receive a fair bit, even indoors.On the subject of engine/alternator/blower fan interference, I've read that wrapping the power cables around some ferrite cores (toroid choke?) can help filter unwanted noise, anybody here have any experience with that?
My new baofeng just arrived in the mail. What do I do now?
>>2003498Program. You did get a programming cable didn’t you anon?
>>2003540I did remember to buy that. Will watch ham radio crash course. He will tell me what to do.
>>2003585It’s not too hard if you use CHIRP. Good luck.
Are window mount antennas cb antennas garbage? I would get a magnet for the roof as everything I’ve read tells me to put it centered on the roof, but I put ladders on the backrack and they would hit the antenna even if it was one of the shorter models.
>>2003814you want a nmo mountdrill a hole in your roof. HAM is more important than having a weatherproof car.
>>2003820Thanks. Personal truck got a roof hole the other weekend. This is the work truck. Even though I'm the only driver and take it home and handle all maintenance and paperwork the title is in thier name. I don’t want to answer any questions from the bean counting peanut gallery the few times a year I see them.
Did anyone actualy install ham radio or station in their car's single dim slot instead of car radio? How did it go and did you get any interference regarding electricity in car?
>>2003847You need to remember to allow a little space for cooling.
>>2003904that sounds a lot like a no to me
Former radio installer here.>>2003814I wouldn't touch a window mount antenna, But having an antenna is better than no antenna.Because good CB antennas are so long, I would recommend ordering an antenna mount for your truck. The fit inside the lip of the fender.Unbolt the side panel, pull it away from the vehicle, tighten it up while pulling. You can get _Just_ enough space to fit the coax in there. You don't want it pinched.Run the coax through the firewall.>>2003847We did those from time to time. Although it was with radios with remote heads. Some of the newer trucks computers broadcast in the 2m band. There is nothing you can do. It's just so noisy that the antenna picks it up.Sometimes a vehicle has noisy power. Good power conditioners are getting harder and harder to get. It's fixed with an inductor and two capacitors.
Hi, anon who was interested in the Yaesu VX-6R here again. At that price point, is it worth it to just jump up a price tier and get a 3-400 dollar one? I want it to last and be a long term investment so I'd rather cry once buy once but even for me the 6-800 dollar ones are an oofUnless you can convince me it's seriously worth it I guess. I have more than that in my rifle and my radio is far more likely to save my life
>>1999369What constitutes broadcasting exactly that makes it different from a normal legal transmission?
https://rbt.asia/g/thread/79363078/#79371884>I live in Poland and there is a professional troll guy in one of the cities who has been pissing off truckers for like 20 years now. He's been an object of an intense witchhunt to beat the shit out of him and they suspect he must have a really powerful radio rig because he's heard everywhere. They have never been able to successfully triangulate himIs this plausible?
>>2005043On CB. Yes. It's the /b/ of the airwaves. It's what happens when you say "sure, anyone can do what they want in this space because we don't give a ****".
>>2005043>plausible20 years still cannot triangulate a strong signal? No, it is impossible
>>2005066Maybe his rig is on a vehicle that transmits from a random different place every time.
>>2005025Broadcasting is generally defined as one-way transmissions intended for a general audience.
>>2005099So you can only have one-on-one conversations and the likes?You can't for example put on an album you've made?Wha if you talk to a few friends about your thoughts on something, and that group becomes larger and larger? Does it gradually become more and more a broadcast until you're well over the treshold whre it's definitely a broadcast?
>>2005066If done by retarded truckers it's possible.How many fox hunt enthusiasts give a shit about a CB shitposter?
>>2005102As long as you’re having a conversation with another operator or operators it’s not considered broadcasting. But hell, I ain’t your dad. Do it if that’s what you wanna do. Certainly more interesting than boomers discussing boomer things.
>>2005107I mean, I wanna do it but I don't want to get fined.
>>2005111There’s unofficial pirate bands where people have broadcasted for years without prosecution. One popular one is right below 40 meters so if you can TX out of band that’s one place to go.
>>2005114Will look it up, thank you.
Not trolling... what's the draw of this hobby?
>>2005066>20 years still cannot triangulate a strong signal? No, it is impossibleIt is hard but not impossible. Either he is lucky or he has a background as a military radio op. There are many well known stories of sources that are hard to triangulate even though these are hard. I cannot find the story anymore but I remember a case where a boat jammed the GPS signals and as such became important to locate. Due to multiple reflections this turned out to be hard but after a long high priority search it was found an antenna amplifier had malfunctioned and started emitting in the L1 band. In another case a GSM net was jammed on a regular basis but it took a long time to figure out that the source was a GSM booster installed in a ferry that passed by.In this case the emitter most likely actively seeks to evade the hunters which makes this a lot harder.
>>2005127What happens when you get caught causing trouble like in your examples but it's a malfunction and not a deliberate act of disruption?Do you still get in trouble?
>>1998661yeah.. except hams tend to be more technically knowledgeable having had to study for exams. Any idiot can shit post into a mic, only a few can engineer shit together and understand why when things don't work
>>2005131I don't know but I would not think they got into trouble. After all they had used a factory made device that unbeknownst to them had failed.on the other hand there is a lot of pain awaiting truckers using GPS jammers to avoid being monitored by their employer's fleet monitoring systems. This is intentional and causes a lot of grief including disrupting emergency services. Experience is that these too are very hard to catch and the employers who should have seen that something is up never alert the police to a jammer most likely being used.

>>2006014Ok faggot. Thanks for the help
Alright boys, either this will be a mind bender, or I've completely forgot something exceptionally simple.I have a jeep and an old 10m / CB transceiver, and instead getting a standard mobile CB/ 10m antenna like a normal and well adjusted individual, I decided to have some fun and make use of an AS-3916 military Antenna I acquired.The problem is, I only have the "Antenna" side of the system which includes the aerial rod, spring and retaining nut (colored black on the pic), but do not have the base (colored tan) in which I have to assume the "Ground" side/ reflector exists. So, what things can I use to make a diy RF ground / reflector/ counterpoise to make this balanced? Note that this Jeep has a fiberglass body and canvas top, so roof mounting or using the body as an RF ground isn't possible. Even in it's current state, it seems to receive decently well, but SWR readings are entirely inconsistent when transmitting, going anywhere between 1.2:1 to 3.1:1.Would cutting open a soda can or some such metal or aluminum can, flattening it and placing it under the antenna and connecting it to the radios' RF ground work? I've tried to look around on various search engines for info on diy ground planes with little success in finding anything applicable to my situation.tl;dr need ideas for ground planes for an unbalanced mobile whip antenna being used with a vehicle that doesn't have good ground plane to begin with.
>>2006252If you can open the upholstering inside, you could fit a metal plate under the roof and lay a grounding cable to attach it to mass somewhere. And put the upholstering back.
>>2006264The canvas is a single sheet, and honestly would place the antenna so high that it would hit everything i drive under. I currently have it mounted above my tail light and still hit most overhang signs at drive-thrus, etc.Pic related is the mounting bracket. It wouldn't be impossible for me to place a metal plate below it, but I honestly don't know enough about RF Grounds/Counterpoises/Reflectors to know how large it would have to be to be effective.I know, for instance with a dipole, the RF Ground side needs to be equal in length to the ANT side. But for a Vertical Whip, how much material (or in this case, how large would the reflector/ground plate) would be needed to make the necessary balance to the antenna system?
>>2006269Also note that isn't my actual vehicle, just trying to show what the mounting bracket looks like
Is it legal to talk on the local fire dispatch frequency(154.16)
>>2006284tell them about fires that aren't actually thereit's a great laugh
>>2006252Is the whip 108" long? In the pic it looks way to short for CB (11m). Normally people who run 108" whips fold them over and tie the end down with an insulated hook.
>>2005507>Sometimes I don't want to broadcast my position to anyone who can pick up.Isn't that the whole point of APRS?
>>2005111Nobody gets fined for shit on amateur radio. The FCC could care less about it unless it interferes with users who pay big bucks for spectrum (aka the cellcos) or ones that could get them bad press (police/fire/military).
>>2005613what is the advantage of those thin wire ones anyway?
>>2006323Easier to reach the prostate if your BMI is over 50.
>>2006308The rod is 64 inches, 68 including the spring. However the spring coil (to my knowledge) acts as a lengthening of the antenna electrically (as in the spring is part of the radiating element, not an isolated spring for flexibility).That said, it's meant for use ideally between 30-88mhz, but it should be noted that in reality we used them with HF sets as well.
>>2006329And that 4 inches of spring is it's length coiled, I'm not sure how long it would be if laid flat, but I have to assume it would be somewhere in the realm of close to the proper electrical length for 30mhz at minimum.
>>2006327what if I already own something made specifically for that?
>>2006334Then the thicker shorter one will do just fine.
>>2006329>That said, it's meant for use ideally between 30-88mhz, but it should be noted that in reality we used them with HF sets as well.Ya on radios with built in auto antenna tuners. Are you running a tuner? Because a 68" antenna is not resonant on 27mhz. All CB antennas are electrically around 108". Shorter antennas hide the extra length in loading coils. Or wind 108" of wire around a fiberglass rod (FireStik style antennas). If the coiled spring isn't insulated wire then it only counts for 4"Lack of counterpoise isn't your problem.
Has anyone else seen this yet? Pretty fishy stuff, eh?https://docs.fcc.gov/public/attachments/DA-21-73A1.pdf
>>2006350>It's illegal to use your radio when doing illegal things. Noted.
This implies ARRL supports its misuse for reasons that do conform to their values, right? a lawyer approved this?
>>2006347>Are you running a tuner?Unfortunately, no.I'll be honest, I didn't realize that that coil would need to be insulated to make it count for more than just it's physical length. I know that in the older versions of antenna systems that filled the same role, that the bases' had antenna manual antenna matching circuitry built in to them that could be manipulated with a 5 position switch on the bottom, however the bases with this antenna lacked them. I think it's fair to assume there is something inside the newer bases as well.So my options then are either to somehow electrically lengthen the antenna, or cut it shorter to make it resonant? And even when I reach that point, I will still have to deal with the lack of counterpoise as well.
>>2006358>or cut it shorter to make it resonant?It is already to short. You said its 68". The min it can be is around 108" for CB. 1/4 wave. Hustler still makes a decent ballmount/108" kit. If you want the best of the best look at breedlove.>https://breedlovemounts.com/store/ols/products/cb-ball-on-3-in-plates-with-ring-terminal-connection
>>2006364What about lengthening it via either wire coil or welding a second rod onto the first?I realize I'm being stubborn and the easiest thing to do would be to get that breedlove kit, but I'm also using this as an antenna theory learning experience.
>>2006370>What about lengthening it via either wire coilThats called a loading coil. >https://www.w8ji.com/mobile_and_loaded_antenna.htm>>>2006370>welding a second rod onto the firstSure.

WaitSo monopoles require a bigass ground plane, right?monopole = inductorplane = capacitorIs that right?

I've an unsolved issue involving Airspy SDRSharp and the internal Bluetooth device.After a random period of time using said software the main internal BT adapter malfunctions and my BT mouse freezes.Sometimes the program also freezes.And the only way to have it back is powering off the computer completely.No internet info on the issue. I've tried different combinations of program versions and RTL dongle drivers and software configurations. Also different BT drivers, process priority levels, and USB power saving options.Maybe If there were still a way of avoiding Airspy to access the BT device I could solve this.
What is the best 40m HF antenna to setup in a very limited space? Don't really have anything I can put it on so a wire dipole isn't going to work.
>>2008591Magnetic loops can even work from your home. 40m shouldn't be much of a size problem.There's even "double loops" that are basically two turns of a coil to make them even smaller.Main problem of magloops are that they require their own tuning capacitor.Thinking of a double-wound 160m loop myself.Do your research in that direction:http://vk6.org/160M_Loop/
>>2008529>cheap chinkshit doesn't play well with my computerDon't use chinkshit SDR dongles.
>>2008655Except is does play well. If you read correctly I don't mention there is an issue with it.It is the software sdrsharp that triggers the problem. Even if I don't install the dongle drivers and don't insert it into an USB port, just running the program alone eventually causes the issue.If I disable the BT capability in the computer the issue is gone. But I need it for the mouse.
>>2008810>durrr>I need the software to use the dongle>The software crashes my shitYour chink software for your chinkshit dongle is shit. If you don't have a reliable way of controlling the hardware, it's broken trash.

so it's the future, discrete components don't exist anymore and all electronics are complicated 3d printed blobs that resemble the internal organs of a lovecraftian horror. There are no more analog potentiometers, variable capacitors, switches, everything gets converted immediately to digital and talks using weird digital protocols. Something has gone wrong in space and you need to phone home, your spaceship has a working radio, but because you failed to pay protection funds to the Venusian mafia, all systems have locked you out.

To build the potentiometer you could use a sliding wire on a pencil led.Using a zinc strip and a blow torch you could make a RF oscillator.Capacitors could be made with scrapper circuit boards sandwiched together with a piece of flexipaper* between them. Adjusted by sliding them apart.http://www.sparkbangbuzz.com/els/zincosc-el.htmOld school morse code.On the receive side, a regenerative receiver would be the way to go.

And because AI's doing some of the design work for us, we have batshit crazy circuits we barely even understand. Like we have a variable transformer that has layers of semiconductors to turn on or off each winding. It also has integrated cooling and a bunch of piezoelectric stuff that simultaneously adjust flow rate, act like a capacitor, thermometer, and to the best of our knowledge probably have something to do with frequency regulation.>>2009553there are no circuit boards anon.

How fucking dead are repeaters generally in the US? I currently live in the south east corner of Wyoming and I'm still amazed that they expanded a local network from just 2 sites in the county I live in to sites across multiple counties extending into Nebraska including wide area repeaters and covering over 100k people yet there's still almost no activity. Today I just found out what a small puddle this network is compared to the ocean when someone representing a Colorado based repeater network approached local club members about linking up. This is their Colorado based network:https://skyhublink.com/coverage/This shit covers a large portion of Colorado and Albuquerque, New Mexico, or 3.5+ million people, and even allows people to connect over the internet from repeaters in other states using every popular digital voice mode. How dead do repeaters elsewhere have to be to make such a thing possible?
>>1998658Any good ways to mount a ham and CB to my car that aren't magnetic mounts or drilling into it? I've got a Honda Element and can't mount them on my roof because my drive has a couple low clearance areas I wouldn't be able to get through.
>>2009633>Any good ways that aren't magnetic mounts or drillingNo
>>2009625I had a similar experience in Canada. I was in NL transmitting on a local repeater. I didn't realize it was being simulcast to various repeaters in various provinces.Lots of people lurk. But who wants to talk to a stranger? Make new friends? Lot's of old fartsLocals talk to locals. But some of the best conversations I have had are on those "dead" networks.The trick? Call CQ CQ CQ and throw your call out there. At least one person will come back and tell you that you don't need to call CQ on a repeater. This fills up the airwaves and the people who are scanning around pick it up. Start yourself a pileup and talk to people with similar interests.>>2009633Fender mount is fine for VHF/ UHF (not so great for CB I'll explain later).I'll even give you a protip.When you install the fender mount on your car, loosen the screws shown in red. Put on some gloves and pull HARD on the panel. You want to move the panel just enough that the coax can slip between the hood and the fender. If it pinches it will "pinch" your signal. As well as degrade the coax and damage the paint (in a very small spot). When you pull back you may need a second person to tighten up the bolts while you pull.Then take the coax and run it into the vehicle.You will want a fender mount. Then a NMO to FME cable.Poke a hole in the rubber grommet that is located on the drivers side. This allows all the wires in the car to pass to the engine/ computers etc. This is the firewall.Pass the FME connector through the rubber grommet.Feed the coax inside the vehicle.You will want to use zip ties and cable tie downs inside the hood. Make sure that when you close the hood it doesn't cut the coax (rookie mistake! :D )Once the coax is inside the vehicle you want at least 6 feet extra length. You can hide this underneath the drivers side carpet. Don't coil it. Zig zag it. This prevents impedance issues. Run the coax to the final locationUse an FME to Whatever you need adapter at the radio
>>2009649Here is a picture of what the grommet in a car looks like.Be very very very very fucking careful not to nick those other wires. It is an absolute _#*%*_ to fix.
>>2009649The metal on the side of a car does not provide an adequate ground plane. You really need to be in the center of a roof or large metal plane. But if that's all you have... That's all you have. Go for it. It's better than nothing. Comms beats no comms.
>>2009649https://www.radioworld.ca/lar-nmokfmeThis is an example of the NMO to FME cable with connectors.However the picture on that web page is wrong.Picture is the cable tie downs.Use self tapping screws and make the hole first, then use them with the cable tie downs and coax.

>>2009676Thanks for the thanks, it's appreciated.Pro-tip. If you install the NMO as is, it will last about 3 years before needing replacement. If you use a drop of silicon on the bottom where it transitions from coax to NMO it can last 5 years.Don't want holes in the dash? Mount the bracket for the microphone on the side of the radio.Mount a rare earth magnet to the inside of the dash with some silicon.

How do we level the playing field for black trans women interested in amateur radio?
>>2009909two tin cans joined by a long piece of string?
>>2009909You saying that nigger trannies are too stupid to pass a test?That’s racist and transphobic man.
>>2010017They also need an ID to take the test which is racist and exclusionary.
>>2010038>IDs are “racist and exclusionary”Yeah whatever. Fuck ‘em. And fuck you too. Back to plebbit you go.
>>2010044I guess it makes sense that the ham radio general of 4chan would have some of the most autistic retards on the planet.>>2009909How about mandating some sort of tone along the lines of "-.-- .-.." at the beginning of every ssb transmission so that other hams will know that it's a YL regardless of their voice. That way they can enjoy the privilage that they deserve of being a woman on the airwaves.
>>2010075I’ll give you the autism part however not buying into your nonsense does not in any way make one a retard. On the contrary, making statements without any basis in fact is retarded and can be dismissed outright.
>>2010079hahahahahaha what a fucking retarded faggot

>>1999369What country are you from? Its legal here so long as you have a license and keep the content within the regulations. There have been ham guys running broadcasts since the 70s here. Its mostly talkback style stuff. The main station broadcasts and takes callers on other frequencies which they put to air. In some cases they just broadcast reruns of the above. There has been one guy who simulcasts on three bands plus streams.
>>1999733Just filter the md5 of the picture.
Newb here, just got the RTL-SDR v3 and tested DAB decoding on it. Works fine but there's something I'm wondering about with these DAB broadcasts. From what I see, the government broadcasts have a higher bitrate (60-80 kbps) compared to commercial radio (32-48 kbps). For some stations, even FM is better than the bit-starved stream on DAB. Yeah I know, the bitrates are absolute shit but decent for talkback shows. Is this the same with any of your countries that have DAB broadcasts? Pic related, cartoon singing from a Australian government broadcaster.
Can you get a usable signal by rectifying SSB as if it were just AM? What does the result sound like?
>>2010596No. It sounds thumpy, distorted, and staticky. If you insert a carrier, it sounds much much better.When amateurs first started with SSB, AM guys would have trouble hearing them. So they would do SSB with the carrier so they could explain it to them.
>>2010605shit.> If you insert a carrier,passive addition, or a multiplier?
>>2010621https://vk3ye.com/projects/projbfo.htmEither directly at the desired frequency.Or you can inject the BFO at 455KHz where it has already been down converted. Then you don't have to move it around.
>>2010491Analogue wideband FM has a far superior fidelity to DAB yes. But the marketing shills may espouse the other features DAB has.>SSB with the carrierI've seen some hams run that from commercial band HF gear which is primarily designed for USB SSB use.
>>2010491>why does commercial radio use lower bitrates because they can? HE-AAC/DAB+ was *designed* to work with very low bitrates, more so than it's predecessor. 32kbps HE-AAC is goodenuf for modern music (especially when played in less than ideal conditions rather than headphones), whereas 32kbps mp2/DAB is unintelligible for anything. >why does govt radiothere's likely no financial incentive for them to multiplex and cram more channels into a signal, maybe they're legally required to broadcast a certain minimum bitrate, idk
