Anyone in this thread have experience with lorawan or other data/radio systems? I’m thinking of building a remote license plate reader using a raspberry pi and doing the image recognition ML on the pi then just sending the binary data back to my house without using cell or wifi (somewhere between 1 and 5 mile distance), so I think lorawan is the way to go but maybe you guys have other recommendations on radio systems to use. I think I need to have the pi send datetime stamp, license #, confidence %, encryption key, etc. and because the extremely low bandwidth limits of lorawan I think I’d need to store 5 or 15 minutes of license plates before sending it in a batch, and probably include something like the prior several batches so I can be sure to get the data even if one transmission fails. So the data size is probably ~40 bytes per license plate and 50 cars/minute means 2kbpm or ~32 bytes/sec.Lorawan and a pi and camera are pretty low power (a few watts for the whole system) so a battery will work for v1 but eventually it’d be neat to go fully stand-alone and have a solar panel and charge controller to keep it running perpetually.
Why are so many of you so fucking fat?

>>2288585I'm just big bone
>>2288555seems reasonnable and quite the kind of application for lora
>>2288555Checked. I *think* this would be an ideal application for Lora but I don't have any experience with it. Be sure to keep us posted if you go that route, lots of people are interested. If you have line of sight you could use wifi. You can also send a limited amount of data over MURS but you would need to find a type accepted modem which might get expensive and complicated. Also consider ZigBee or some other 802.15.4 implementation.
Does anyone use N1MM?I'm having some success, but would like to use my PC for the receive audio via bluetooth.
>>2288793I did it!!!!!What a great upgrade.N1MM shows spots, and you can spot other calls.And you can scroll via your screen.And a big ass waterfallAnd audio into your PC to bluetooth so the wife and kids don't scream
unironically use the /hrg/ as a propagation beacon. If it falls off the catalog, bands closed. Comes back, so have bands
>>2289004could also just check wwv and see what band is open
>>2289006I got a letter from the fcc last time i shitposted on wwv frequencies though
>>2289021What did they say? QRO?
>>2289021no like2.5 -> 1.85.0 -> 3.5-3.910.0 -> 7.215.0 -> 14.220.0 -> ~17m and upnot perfect but usually a good way to judge propagation

>>2288555>somewhere between 1 and 5 mile distanceWhat is the terrain, topography and soil type? There are many alternatives here.
>>2288478>tuning through that one HF websdr because i killed my only HF-capable SDR years ago>hit 3940KHz>ears blessed by "YOU ARE A PIRATE" jingle and some russian shizo going on about ukraine or some shit>audio preemphasis and fading are so strong that i can't make out anything
>>2289904sounds like a good night
>>2289783What are some other options? I’m new to radios so I really have no clue if lorawan is the best choice or not. I haven’t messed with a pi in a few years and lorawan wasn’t really a thing then (and the projects I did then all used wifi)5 mile distance is my “reach” goal— in that case I think the base station will be about 400 feet higher in elevation than the raspberry pi. Heavily wooded and hilly area. I don’t think it’s line of sight but it might work anyway (from the radio waves bouncing off the hills/trees etc). The uncertainty with the range of the system in my use case is why I said between 1-5 miles. If it’s I put the remote station 1 mile from the base station they’ll be at the same elevation: definitely line of sight with few trees and no hills blocking the signal.
>>2288778>>2288636MURS looks like a more powerful version of the FRS radios I used as a kid. That gave me an interesting idea: It’d be epic to make the remote raspberry pi transmit the plate numbers like a number station, where a text-to-speech voice reads the plate numbers and transmits over a standard FRS or MURS radio. Anyone listening in would go nuts listening to it constantly reading off ‘random’ numbers and letters. The retrofuturism is appealing.
>>2290130That would be fox hunted and destroyed so fast. You could probably get away with using FRS or MURS, but you'll want to do so in a way that's not audible, and TXs the data as fast as possible. I'd also suggest a yagi running the absolute minimum amount of power needed. The less anyone knows it's there, the less anyone would care about stopping it. Also, if you have LOS, using something in the GHz range is going to not just be potentially less noticeable, but also have a smaller antenna.
Are there more commonly used satellites, or is it just based on region?
>>2288555>It’s a type ofLow Power Wide Area Network (LPWAN)that uses open-source technology and transmits over unlicensed frequency bandsI'm not familiar with transmitting data outside of FT8, but I do have a programming background I haven't yet brought to the hobby.There are power over Ethernet security cameras that read cameras. I'd probably start there, step any unneeded data, then alternatively transmit between the CB freqs or wherever lpwan recommends.
>>2290155I have heard that the feds care a lot about illegal radio shit and shut noncompliant stuff down with extreme prejudice. But what if it was legal (but annoying)? Then neither the feds or private citizens would have standing to disrupt it, right? Are citizen radio people aggressive enough to come on my property and wreck my shit?
Doing it on CB would be pretty based. Use channel 17 to get the Q people in an uproar + some dx possibilities. There's pretty much no rules on 11m>>2290130
>>2290234>have heard that the feds care a lot about illegal radio shit and shut noncompliant stuff down with extreme prejudice.It's extremely rare and it's even more rare that it is enforced. They only care if you are interfering with emergency services. Here's a video of a gmrs guy, who knows more about radios than most hams, talking about FCC enforcement:https://youtube.com/watch?v=SHORHX1LBu4At most you piss off a lot of people. If they come onto your property and destroy things, then they are committing a crime.
>>2289560kek its real.
>>2290234What you described I don't think is legal on MURS or FRS. You need to go to the FCCs website and read the licensing for the two. Generally, no. There are handfuls of hams though who get very bent out of shape over shit that's made to be annoying. Mostly it will be the feds destroying it after its confiscated. Which is why it's not beneficial to draw attention to yourself. You might get a year or so from it, but sooner or later you'll get letters from the FCC, before you get a knock on your door. Just stick it on wifi with a yagi or parabolic antenna. It'll work better, anyways. >>2290341The feds aren't the ones to track these down, unless it interferes with businesses or EMS. Fox hunters do, and then report it to the feds who start with letters to cease the illegal activity, followed by agents if the activity doesn't stop. Or they destroy the unit, and OP is out the equipment. Even if OP has security cams, the likelihood he ever figures out who the guy is is extremely low.
>>2290439this. honestly if you get a really good antenna, hell there's even dedicated systems for just wifi that work over a few miles (i think even LTT did a video on them at one point?). go with that. extra power doesn't mean anything if all you have is a shitty antenna.
>>2290116>What are some other options?There are really a lot of options, that is why I asked the question. If you have LOS (Line of sight) you could use RONJA which is license free.
>>2290155>>2290439Why are you saying this isn't legal on MURS? I can see why someone might question it, if it sounded like a broadcast vs. point-to-point traffic, but you are absolutely allowed to use MURS for telemetry. Still, I suggest finding a way to use encryption. License plate numbers are PII, and combining those with a location and a time makes it somewhat sensitive information (but probably not legally controlled, at least not in my state). So it's a good idea to have some privacy controls.
>>2290548sure you can use MURS for data transmission. but encrypting it is a big nono. plus this gets the added problem of other people in the area having access to these channels pretty easily. all it takes is one kid to start using the same channel for everything to fall apart
>>2290556Crypto isn't specifically disallowed on MURS however you need to stick with one of the authorized emission types. So while I'm not aware of any off-the-shelf equipment that lets you use legal encryption on MURS, it's not true to say that it's not allowed. In any case, with marginal line of sight I would look into 900 MHz wi-fi. Ubiquity has some affordable equipment. You can use encryption, reasonably-sized antennas, and some penetration through foliage. And you get a full-blown network connection.
>be Yuropoor>scan through repeaters>suddenly Echolink>Ohio ham connects*kerchunk*>mfw
>>2290449We have one by Ubiquity that has a ~3 mile range at ~500Mb/s. Course we're only going like 1/4 mile, which funnily requires that we aim them slightly off of each other or they overload each other, even at low power.
Saw a radioshack realistic navaho trc459 base station at a local thrift store for like 40 bucks today. What’s the general consensus on buying 30-40 year old radios of dubious condition (seems to power on) and what would I even do with this thing if I went back to grab it?
>>2290561fair enough. i just assumed it was the same as ham rules on encryption.>>2290636for a cb i wouldn't pay more than 30 for one, even for sideband. its just not as used other than talking the shit with whatever crackheads are in your areaas for using it...get it on air with a good antennatry to talk to the retards on ch6give up and shelf it
>>2290636Sometimes you get lucky, there are obscure corners of the internet where people collect technical manuals, schematics, modifications, etc for various old CBs. And if you're really lucky it might just work. It's interesting equipment from an interesting era. If the cost is right and you have space for it why not pick it up to tinker with? Also CB is getting more popular again and has a distinctly different culture than ham.
>>2290548>>2288555I don’t know if license plates are pii. I think all states have a concept of being “in public” where people do not have an expectation of privacy. It’s no different than if I stood on a corner and wrote the plates down of cars that passed by. Or like those earthcams of Times Square etc, they record all that data and transmit it to the internet and that’s 100% ok because in public there is no expectation of privacy. Also, don’t truckers say plates over cb?
>>2290833Stop thinking like a ham. Your name is public but it's also PII. Your home address is public but it's also PII. And yes, license plates are *obviously* PII. PII plus a time and location is more sensitive than PII by itself. To reiterate, I am trying to say that it's generally not illegal to transmit this data in the clear, but it's still a good idea to have some privacy controls. Would you want someone following you around 24/7 and posting your location on tw*tter?
>>2288478What do yall think of the X6100? I have experience with the 5105, and have been around and used the FT891. The X6100 looks good, I live in an apartment and everything. I do is Based on being mobile, but I also don't care about QRP and only doing 5W. Any opinions on the X6100 would be great, thanks.
>>2291075>X6100It looked interesting but performance is below expectations:https://qrper.com/2022/01/overloading-the-xiegu-x6100s-biggest-negative/
Still want to get into ham but have no time or motivationKind of want to base all my designs off vacuum tubes and make my radios EMP-Safe...Idk why but it is a desire.
>>2291126Based. EMP hardening is a very obscure and interesting corner of electrical engineering. People say that tube-based designs are a good way to go. I'm sure it can be done with modern components too but you're going to struggle to find any public resources about how to do it. Believe it or not, some small level of EMP resistance is quietly baked into the design of many many of the ICs in modern electronics. However I think the goal is for the device to fail gracefully rather than continue operating through nuclear armageddon.
>>2291066Yes, but you can’t DO anything with just a license plate number, unless you have a law enforcement friend or access to a database. With just a name, sure, you can take the name and look up their address or phone number. Type a license plate number into Google and you’ll get back nothing.
just got a kenwood ts-711seems to be a really good rig so far, may end up with an amp later for a big more coverage but a better antenna is first on the list.
>>2291241It takes effort to do anything with a name or address, too. I don't see how that changes anything. Obviously the sky won't fall if you choose to share ALPR data. It's already shared widely among glowies, law enforcement, and various companies that don't give a fuck about regular people. I'm just talking about good engineering practice. You know, that thing that hams like to larp about.
>>2291126>EMP-SafeEven the people who actually study this stuff say there is only a 40 or so percent change that if an EMP goes off, it will fry your electronics if they are turned on. Even then, the probability of it happening is next to none and faraday caging things is easy. Don't give into the Doomsday bullshit.
>>2288478What's a good UHF quarter wave for under 20 bucks? I tried to get this one but Amazon lost my package.
>>2291426i use this mobile. it works fine. swr isn't bad, at least with the one i got.
>>2291431By any chance, did you test the SWR up in the GMRS frequencies? I've been considering getting something like this for indoors. Sadly it won't work on my vehicle, the parking garage at my new office has SIX FEET of clearance. WTF is up with that anyway?
>>2291437i didn't try it on grms, my meter only goes to 150mhz. ended up building my own for gmrs out of some pvc, wire, and an old cb mag mount base. goes over 20 miles at 15 watts
last thread i had asked about cheap lmr-400 and you guys pointed me towards drf-400. it looks great and all, but one question. where the hell do i buy it?i've seen that amateurradiosupplies.com has it, even with connectors. but are they trustworthy?and even aside from coax, where do you guys get your gear from?
>>2291458Very cool. Yeah at one point I DIY'd a ground plane antenna but I really didn't like the radials sticking out at eye level inside my apartment. So now I just stick my NMO mag mount on a baking pan :)
>>2291474wdym? for gmrs the radials should only be about 5-6 inches long
>>2291431Use this as well on HT in vehicle until I find a mobile radio I like for my vehicle. It works great. Hits a repeater 30 miles away no issues at 5 watts. UHF/GMRS is not as good, but it still does the job and hits the DMR repeater I use 10 miles away, but GMRS range is about 5 miles.
>>2291478Ehh it was dual-band so the radials were like 20 inches. Although you make a good point, maybe I should put that thing back together and trim it down for GMRS only. Might look better than an old baking pan.
Any recommendations for a bluetooth adapter so I can operate my radio wirelessly?
>>2291487ahh gotcha. yeah def trim it down if you are gonna use it for just gmrs. i have a little one and it almost looks like some sorta art
>>2291494Cool. Thanks for the idea!

Hey guysI'm a Low iq tech illiterate, recently i took an interested in Ham Radio and wanted to start with buying an RTL-SDR dongle to mess around with it and use it for listening to police radio scanner, Listening to aircraft traffic control conversations and tracking planes, receiving satellite images etc.and i was wondering if this dongle can do all of this :>https://www.walmart.ca/en/ip/USB2-0-FM-DAB-DVB-T-RTL2832U-R820T2-RTL-SDR-SDR-Dongle-Stick-Digital-TV-Tuner-Remote-INFRARED-Receiver-with-Antenna-black/42T28RJ9WDOLi'm asking cause if i read the description (check in the website below) doesn't seems to match up with a R820T2, and i don't wanna buy an R820T or worst an FC0012 because that would be extremely useless and a waste of time/money.Plz note that linking me other dongles or telling me to buy an rtl-sdr blog one or a Hackrf one/clones is useless, i'm only asking about this since this is the only thing available and also the website that i linked is just an example.plz no bully i already stated that i'm a low iq retard.
>>2291628I made the mistake of clicking on that redd*t thread. They were both promoting the idea of announcing pronouns over the air, and deeply offended by the the existing use of "OM" and "YL". Wat.
Been thinking of fucking around with tape measures again. One idea is to use two ~16ft' 1" tape measures and make a 20m vertical in the same manner as ABBREEES are made (so a sandwich, giving it rigidity). Anyone hear of anyone else trying this?
>>2291839Redpill me on HF verticals made out of measuring tape?
>>2291829>RTL2832U + tuner R820T2It's ok, but the black one is not a R820T2, the new ones are blue so this particular one, riskypicrel 820T2 written on it, you have to find that
>>2291839Will you use radials ?
>>2291926>the new ones are blueAs i stated before, the Walmart link that i posted is just an example, so yeah i think it's blue (at least that's the pic used for it).whenever i google this stuff that are in the description :>"VHF-174928~ 239200 KHZ">"DAB radio: L-Band-1452960~1490624 KHZ"most of the google results are for the R820T & FC0012 , not for the R820T2, that's why i'm asking.Is there anything wrong about it or am i retarded ?
>>2291982the R820T2 is capable of that too, it can receive 24MHz to 1766 MHzyou ahve these results because the R820T and FC0012 can receive only certain bands, they have quite some holes int the spectrum they handle IIRC

>>2291878I can't really, I've only seen people use them by hanging the tape from a tree, as small VHF/UHF J-poles, and as yagis. >>2291929I'm thinking I will. I got a 1-1/8" wide 35' tape measure, that I plan to cut to ~16' when I get around to running a calculator, so it's my understanding I'll want radials. Before messing with that though I need to cut it and see if it can even support itself at that length. Eventually I'll also heat shrink the entire thing to give it even more rigidity (provided it looks promising.

So quiz time: this function needs to occur, who does that job? You got it right? Cool, you passed the course."
>>2292390I asked about the 2 ARRL classes/certs and didn't get much of a response. I wish 4plebs included /diy/They're do-able within a day (including the FEMA requirements). All the answers are leaked if you can search well enough (namely using quotation marks).It is all procedure and bureaucracy, and in the lens of ham radio I'd doubt ever applicable. It's a bunch of dick waving and understanding which self appointed chief gets to do what until another govt agency shows up and more dicks are waved.I now have 2 'good boy certs' in my ARRL profile. That's about all that it will amount to.I went on to apply to ARES and SkyWarn thinking I was creating a nice little resume for a cozy ARRL or FCC job, but I wised up and came to the conclusion it's all about dick waving and dick sucking and I'd blow my brains out in the first meeting of all that red tape.

I'm still kicking around if there's anything to the ARRL volunteer options or if it's 100% jannie work with no upside.There's also something to be said about the FEMA copy and paste 'classes' that count for college credit hours.Maybe someone else can throw in their two cents.
I, a ham, am kicking around the idea of a wireless transmitter on my mailbox so I know when the mail has arrived.DIY research had led me to pic related, a 433mHz window/door alarm. From there I should be able to listen to the signal on SDR or a dual band.Another option could be to re-purpose my pixie that I don't use, but I think I'd need to find a way for it to transmit when the connectivity breaks as opposed to when it is in a loop.Has anyone played with anything like this? Mailbox is 40 yards away, line of sight.
>>2289101What's the story behind this pic?
>>2292577Checked. What's the story behind this pic?
>>2292552>line of sightIt is easier to use an IR LED to transmit a signal when the mail arrives. Use a remote control chip and you can also transmit data such as how full the mailbox is.
>>2292603I'd recommend an LED in the 670nm band and you won't even need a receiver other than the two already in your head
>>2292617Blinking a LED is a pretty advanced electronics project. You'll need at least an Arduino to control it. Or maybe a something that can run Linux.
>>2292621put it in the cloud, no hardware needed
>>2292603>>2292617>>2292621I wouldn't be opposed to a tech solution and/or modding my plastic mailbox. I suppose I can picture the solution - a 'trip wire' that is manually reset when I get the mail.I work from home in the basement and just felt like listening on 433mHz with the dual band right next to me would allow my lard ass to not get up and look.
>>2288478I seem have trouble with my TV:s analog signal and I suspect it could be caused by intended mischievous people. How can I find out?maybe measure the antenna signal in the wall socket with some equipment and software? maybe listen for noise in the airwith some equipment and software?
>>2292647I was just kidding about the Arduino. Some kind of remote door alarm would be fine. If you want to go overkill, they sell alarm products that transmit on MURS. So you could listen to your mailbox from all around town.
Got my technicians license a few years back and never did anything with it. Recently got my hands on a Yaesu FT-101EE and Archer FS/SWR meter from a yard/estate sale. At this point I'm looking at a "no tune" EFHW on ebay for my first antenna. Other than some coax (50ft rg8x?) and a 200-300W dummy load, anything else I'm missing to get on the air?
>>2292712Also, it seems the yaesu is rated 260W PEP on ssb. Is this an "up to" value? The antenna I'm considering says it's ~100W, and from what I understand I should be fine as long as I don't crank the "Carrier" knob too farSorry for the noob questions
>>2292712maybe a choke filter as this is a non symmetrical antenna, you'll get common mode
>>2292717This. EFHW antennas can send a fair amount of RF back down the feedline. You don't want any testicular gainz from baking yourself in RF.
since the efhw uses the coax shielding as part of the antenna, that means the choke is attached between the tx and feedline right? As opposed to between feedline and antenna, as with a dipole
>>2292727Do be quite honest I don't know what the best strategy is. I'm a pansy about RF exposure so I would probably want, at the minimum, an effective choke before the feedline enters the house/shack and also some ferrite beads spaced along the coax after that. And perhaps a couple loops through a ferrite near the transmitter too. This will also help with local interference so it's a win-win-win situation. You might consider also experimenting with some ground radials -- the requirements will be much less than for a normal vertical antenna.
>>2292681Contact your local ham club. They already have the equipment to check this out so you don't have to go through the process of doing it. If it's only happening to you with other neighbors having antennas, then it's within your own home. In either case:*click*
>>2292727choke it as far away from the feedpoint as your most used frequency. >10m? Choke at 5m coax>20m? Choke at 10m coaxYou want to use the shield of the coax of the other half of your antenna
>>2292728At this point I'm just trying to get on the air and see if I catch the bug and feel like pursuing it further. As far as indoor interference/rf emissions, I'll likely be setting up outside in my back yard so not near any appliances. For common mode stuff I feel like a basic ass inline choke is fine
>>2292754Ohhhh that totally makes sense. Thanks bro
>>2292712>>2292716>>2292727>>2292755>>2292761Aw fuck, just realized my technician license won't let me do ssb on 40, just <10. I don't have any ham experience, is it worth getting my general for 40m ssb? I likely won't be chatting people up regularly, just maybe twice a year to validate my setup now and again
>>2292894I would do it in an instant if I lived in an area where HF was possible. Noise is so bad in my apartment I sometimes struggle to hear actual broadcast stations.
Just got my General
>>2292902you're right, don't have much of an excuse. my job's a joke and i have tons of free time, enough to practice my generalhere's my potential setup after ur guy's tips
>>2292938forgot to detail an RG8X coax with PL-259 on both ends between tx and swr meter, as well as SO230-to-SO239 adapter between choke and feedline
>>2292716260 w is actually a measure of power into the finals.This is probably about 100w of power out.
>>2292960Sweet, that would make stuff a little cheaper. I'd only need like a 150W dummy load (might still get big one), and I can run an EFHW 100W antenna without much worry
>>2292938Why the 40m 1/2 wave cable ?
>>2292894I would, it's nice to have the additional bands. Though I got my general the same time as my tech
>>2288478I note a people not using the correct phonetic alphabet. Here is the correct one to use when transmitting.A-AesopB-Bee'sC-CateD-DayE-EightF-FeeG-GifH-HeI-IsJ-JifK-KarlL-LeeM-MancyN-NancyO-OcelotP-PeeQ-QuackR-RumS-SeeT-TeeU-uteV-voilaW-wackX-XeniasZ-Zinnias

>>2293343Welcome to 4chan. Have you heard of this new app called Reddit? I think you'd like it!
is it just me, or does the Ham community consist of:"Yo, check out this 1,000$ mic I just got"And"Lets make contacts across the atlantic with a vertical made out of coat hangers and duct tape"
>>2292955>>2292984>>2293344thanks fellas :)
>>2292051Icom still won't make an affordable mobile or handheld for 1200mhz.Still only wants to give you D Star, won't give you it's close brother NXDN in combination, nevermind DMR.
>>2292397The fuckers in my county weren't even active in a tornado.Maybe if you're lucky and in New Jersey (not exactly lucky), you can convince the EMA director to give you a flashing blue light to put on your call.

>>2292926Congrats! I remember when I got mine. This sub had to teach me what a resonate antenna was along with an antenna tuner.
>>2293459Minus the marketing, it's an FT-817. 5 watts. HF, VHF, UHF.Yaesu beat them to it 30 years ago.>>2293461Pretty much. Somehow it's become a society of twitter or go fuck yourself.
>>2293484I remember when some civil unrest happened here and all the hams did their best to pretend like nothing was happening. Like you could hear the explosions in CHAZ/CHOP in the background as the regulars checked in to social nets to talk about their health status and favorite brand of Walmart face masks.
>>2293488With CHOP, they're being pussies about talking politics.I say talk about religion and politics.
Just looked into the testing schedule near me, looks like if I want my general soon I either cram for a 7am test this Saturday or wait 6 weeks for the next one
>>2293501Exactly. Although you know they won't hesitate to talk politics when a flood zone becomes flooded or a tree is lit on fire and the scientists tell them it's all because of global warming.
>>2293513I took my Extra online this year and it was a moderately reasonable experience. I was afraid every local site would be covid-crazy.Nearly a testing option ever single day. Three VEC join a zoom call and creep on you as you take a hamstudy.org test.>>2293488Sounds about right.
hello guysI brought my baofeng to work today. On the way to work I set it to scan and attempted to listen to some police bands as I drove through the various towns along the way. At work senior staff use walkie-talkies to communicate. I noticed they said uhf/vhf and I thought they had removeable antennaes. I have lots of questions to ask you about these walkies; stuff like, so if these aren't technically ham radios, are they frs or murs? Or otherwise, does the building itself have a license to use radios inside? I don't know much about the hobbie yet, but I think that a detachable antennae evidences a much stronger walkie than a standard murs or frs. should I be able to tap into these radios? I set my radio to scan and I never found their band after about an hour of searching. If I were able to tap into their radio: would it be illegal to transmit on it? afterwards, on break, I pulled up a police band and I found it scrambled. what interesting times we live in. hardly, but that's a good line to end my tale.
>>2293343imagine being so out of it you don't get the reference or that some of it was used in the show.
>>2293567I received my baofeng yesterday. I have a question: I believe it is only effective from the ranges, uh, 108-200, and 400-500? something like that? In the manual it discusses hitting up some fm radio which is in the 90 mhz range so I think maybe those instructions were written for a different model D: or can I reprogram it with the software? at home I just get the weather radio and a bunch of dead sort of stations I don't know how to identify yet, so I thought I'd take it to work to explore with me. No one realized it was under my shirt. If they did, I wanted to surprise them that I was listening to so I could keep a pulse on the work environment with them and they could tell me stuff I needed to know from far away and I wasn't listening to music
>>2293571"hey why are you wearing a radio""yeah surprise guys I have a radio too just like you guys"
>>2293344Got tired of posting your tranny meme?
>>2293567Did they save the manuals for those radios? If not, try to find it online. Those radios may not be FRS or MURS, but have specific business frequencies. The manual will mention what each frequency the channel is set at. You can cross-reference those frequencies if you want to find out if they're FRS or MURS frequencies. The old motorolas at an old workplace did not broadcast on any of the public frequencies. However, I programmed those frequencies into my Yaesu and since I did the MARS mod, I could transmit on those frequencies.
>>2289560I want to start something like this. What should I buy and most importantly who should I listen to? Is it possible to eavesdrop Putin's conversations with Biden and predict the invasion of Ukraine? Did he have unique skills and/or connections in the shady world of spies or anyone motivated enough could pull something like this off? And the first question would be, is this legal?
>>2293588That sounds super cool. I guess I have to get the license now if I want to take my cool radio to work and get on the senior staff member's level without being adopted into it, if they were cool with that. They might take it as a token of, um, neat responsibility-making and share the frequency with me so I can help coordinate the activities throughout the day.OR if it's a business frequency and I'm a guy that works at that business do I even need the license? I'm intending to get licensed but I've only had the radio two days
>>2293596I think this is a good idea. I think that this says:https://www.buytwowayradios.com/blog/2015/05/default_frequencies_for_motorola_business_radios.html that my company pays for a license, so I should be permitted to use my radio on the frequency. now I have a proper question for the art and science of radio itself:don't I must adjust my wattage to properly engage with the radios at work? I understand that wattage is a very important function in radio, and I'd like to understand it better. Practically, does it come off as volume? How will it feel operating a baofeng in a workplace of motorolas? I'll conclude my post here and if any more questions present themselves I'll make an addendum.
>>2293632Power is important but in this case, modulation is more important. These days most but maybe not all business radios run narrowband FM. So you need to use NFM or you will sound very loud and distorted, and also step on adjacent channels.
>>2293596Your Baofeng is probably not type accepted for legal Part 90 (business band) operation. Even if it is, you're supposed to have permission before you transmit on a company's license. In practice this doesn't matter very much if your radio is configured correctly and you're not causing problems, but in theory you could get in trouble for operating like this.Since you're relatively new to radio I suggest against trying to talk to your business on a Baofeng since it will be difficult to guarantee that the radio is configured right. Get a ham license, check in to some nets, and have fun learning the fundamentals.
>>2293582You are obsessed gramps. I cannot post images since I'm imagebanned. Apparently the person I was replying to was a mod.
I had a good laughhttp://w5jgv.com//1970_tower/answer.htm
It's a shame Baofengs are still everyone's entry into radio, due to the prolific spread of 2012-2017 postings flooding the search results.There are better radios for the same price and cheaper radios for the same cost.Have to dig through a mountain of shit to find info on whats actually good for the money.
>>2294063>cheaper for same costsame capability**
>>2294063cheaper for the same capability ? How is that even possible ?
>>2294063Did you take a look at the TYT TH-UV88 ?If you did, what do you think of it ? I kinda want to swap my fleet of UV-5R and derivatives to something more... everything but at a reasonnable cost.I'll give the baofengs at the new hams around
>>2294070Radioddity sells fixed rebrands (in spec emissions/harmonics) for the same price Amazon sells legit, out of spec Baofengs.95% of everything else you see, like most TYT units, are resold/knockoff Baofeng hardware.95% of chinese HTs themselves are practically the same radio hardware, with a different flavor of buttons/screens/antennas, some worse than BF (being literal knockoffs) some better in the emissions aspect (being knockoff/rebrands of the actual new fixed variants), with very few such as the TYT MD-3xx/7xx, or the UV878s being legitimate company IP.And Amazon is just a fucked marketplace now, reminds me of how the Android games have just been filled with total garbage.I've started shopping elsewhere or at the retailer e-stores unless I've found the price really is better/the same on Amazon what with the free shipping and such.

>>2293526Can we take a moment to give Exxon a round of applause? They find out about climate change in the 70s, write a report on it, then promptly double back and tell boomers it's all fake. The dumb fuck eat it hook, line, and rod and even today with BP, ExxonMobil, Shell all stating it's real, they still believe it's liberal hoax. That's some master class 4D chess moves.
>>2288478is he wearing depends?
I also don't have my general yet, so is there much activity on 10m SSB or should I get a cheap Morse decoder thingy and do 40m?I'm the central California region if that helps
>>2294063No one can answer what is truly wrong with Baofengs other than "muh spurious emissions." They're are great for starters. Nothing more, nothing less. I have plenty available if I need to hand them out if SHTF and as back-up. Note, I have plenty of Yaesu HT's as well, with my FT3DR being my favorite.
>>2294249People say they suffer from desensitization in the presence of strong signals. Although my FT3DR seems to do that too so meh.
so what are all police bands encrypted these days? looking at some old $20 police scanners if that helps because the only band I found with my baofeng seemed encrypted but if I'm barking up the wrong tree tell me nowpicrelated I'm the guy a few posts back that didn't replied when people said operating a baofeng at work would be uncivil and I didn't thank but thanks so a little more detail I don't really get bands out here in the boondocks but I'm pretty sure I was on one on lunch break and I think it was encrypted
>>2294361most places are. a lot of rural areas still use NFM tho. i know mine does.
>>2294370cool. I imagine they have a lot more power too. maybe I'll scoop one up.
>>2294399Check your local area scanners list. It's highly likely your police are using P25.Scanners for that would be in the $500-600 rangeHTs in the 1200-1400.The alternative is to get an SDR and have your computer do the decoding. It would be possible to have a home server livestream the SDR's recieved and decoded P25 police acticity to a personal device.
>>2293567>>2293571We have different freq allocations for different things>88 to 107Commercial radio, what you listen to in the car>120-130Airplane to airport towers and other shit>140ham radioetc etc>440more ham radio>450-460business bandDing, ding. Your store should have a license to speak on a certain frequency, which also should be published online.>radioreference.comIn fact, you can find all the frequencies in your area. Airport, zoo, churches, schools, ham repeaters, trains, etc.Take those freqs and program them into your radio via 'chirp' software (free). Now you aren't just listening randomly to unused frequencies.This is baby step 1 in radio.
>>2294361Get a RDLSDR and don't limit yourself to machines or frequencies.

Bros, I've decided that I'm going for extra. Any advice would be very much appreciated. 73
>>2294907Brush up on your senior high school math if you've forgotten terms, and practice.
>>2294907just like i did the first time to get general, used the fuck out of hamstudy.org, until i was getting 80-90% passing rates on practice tests combined with reading through the ARRL extra manual. oh yeah and this time i watched Dave Casler's youtube channel series on the extra license, helped me understand the imaginary number shit and all the other advanced stuff they talk about.
>>2294771>he doesn't know they also work on cellphones as well
>>2294678The Walmart one should be in the 150Mhz range since they have specific radios they use in the MURS frequencies.
why am I just now learning I can print out a physical copy of my license to display AND one to keep in my wallet. God I'm such a fucking loser
>>2295048When you got your license and opened it up, didn't you see the little rectangle at the bottom that was to be the wallet version?
>>2295051the fcc doesn't mail out licenses anymore.
>>2295095Right, I mean when you download the PDF from the FCC website.
>>2294951Yeah, Casler has some really bang on videos. What I'm really disappointed about, though, is that most of the videos have been hidden or made private or other. I watched his 9.1 Antenna video and it really helped me understand antenna basics, so I'm bummed that the rest of it isn't accessible.
>>2295051No, they never mailed me one. I just have the "certificate of successful completion of examination" I got when I did the test
>>2295115>>2295118Yeah I just now realized there's a pdf is what I was getting at

Greetings and good morning my melanin laden sirs. My parents enjoy police scanners, their town is still analog but several surrounding towns have gone over to P25. I'd like to purchase them a new scanner that is 'future proof'. Are there any that are a good deal for the price / capability perspective? What would you recommend as far as a make and model?
>>2292051Even worse in leafland
>>2288478can you use a baofeng as a ham in on what frequencies ranges.
>>2296542yes, all of them
any good/interesting shit to listen to on websdr.org or kiwisdr.com, anons?
>>2296542I, myself, like the 6.7 - 8.4 THz band.
why haven't any of you contacted Tonga?
If this were to happen, could we still do reasonably well with efficient digital modes? Or are we kinda suck with line of sight stuff and NVIS?
>>2296765See you on 630m, fren!
>>2296765I know! We can simply run a coaxial cable to every house and then radio each other through that. I can't believe nobody has thought of this before.
>>2296765>if this were to happenWhat do you mean if.I genuinely don't understand how proven solved theorems confuse you.The solar minima cycles are real and the maths is correct.Global warming is some fake gay hysteria reaction.
I thought you /HAM/hocks might be the autists to query about this.I have wooden building with metal roof i'm using to store cellular 4G LTE modem in because house is too close to trees.I have sprint 4g LTE tower Band 41 (~2500Mhz I believe) 2.45 miles away.Is it true that this type of MIMO antenna isn't effected much if it is pointing at the tower through the wood wall of the shed?Kinda new to this but doing a lot of reading, included in picrel>charts/graphs that I dont understand in case it helps.>stock photo of the ant to better illustrate>diagram showing distance/heights from my loc to the tower
>>2296961At 2500 MHz, a normal wood wall will only have a small effect on the signal. Trees and brush, especially when wet with rain or snow, will have a bigger impact. If that diagram is an accurate depiction of the terrain between you and the tower you should be good to go, assuming there isn't a lot of trees or brush in there.If your antenna gets too close to the metal roof you might see a big difference in RSSI between the different polarizations. That would be a sign to play around with the location a bit. Although honestly that can happen even when everything is working perfectly so don't sweat it.
>>2296992Thanks Bourne, I have it taped against and pointing out a glass window with screen (dont think the screen is metal) Any idea if glass has a big effect on it?
Hey guys, I want to put a 20m inverted vee up on my relatively small plot (100x40'), seeing as how I'm going to be limited in elevation by the materials I have for a mast, how much am I going to suffer if I can only raise the center feedpoint to maybe 25 or 30'? Endpoints will be about 10'
>>2297218Should work fine. My mast is only around 28', and I made it out alright on SSB. At least several states of coverage. FT8 was making it as far as Australia from the PNW.
>>2297047Perfect. Glass has almost zero impact on the signal. I do something similar with a Ubiquiti wi-fi CPE and their suction cup mount and it works great. Except once every 6 months or so when the suction cup falls off.
>>2297260Thanks mate, was only looking to really do CW and wspr/ft8 on it anyway when I get my QDX ordered and assembled. Maybe I'll throw some 10, 6 and 2m wires up there at the same time
Bros, what even is the point of having the 630m and 2200m bands? How could you reasonably make an antenna to operate on these bands? I know that you have to first request permission and coordinates of your station a month in advance and all that, but how could I, someone who barely has space for a 1/2 wavelength 40m dipole, construct and operate such a beast?
>>2297602Use a loading coil brah.
>>2297602>>2297634>Use a loading coil brah.This, but a bit more heterosexual. You need a loading coil and probably a bucket-sized variometer.One like this guy hashttps://www.f6ciu.com/630m/630vk2/630vk.html>pic related
>>2296349bumping my basterds
>>2297693No. You may be able to find a used one for $300ish, but you'll have to look. $500 is about average for new. Yes, they work far better than jacking around with a TV dongle and a computer (or phone like that other autist).
I'm really fighting the urge to not buy a Xiegu and make a bug out kit.
>>2298012>XieguX5105 I hope ? My friend has that, it's a good little chinese transceiver. The ATU is very capable.
>>2298021>X5105My eye caught the G1M's $250 price tag but my head gravitated towards the G90 at $400.If the ATU is as you say, that's a very tight and cheap package.
>>2298022The G1M would be nice if it wasn't limited to 4 bands, and not even 10m. Maybe for bug out bag it will be enough, it covers popular bands.The G90 is appealing, I don't know if it's good or bad
>>2298022Avoid the G90 if possible. There is a common issue that it downgrades its power really low permanently if you just decide to detach the unit head just once, even if you decide later to reattach it. The cause of it is unknown, as it does not look like it a pin issue. Even doing a complete reset doesn't fix it. If you really want a QRPportable HF unit, keep a lookout into the Xiegu 6100 as it was hacked a month or so ago.
>>2298027>Xiegu 6100 was hackedThat's so tempting.https://www.youtube.com/watch?v=BefYKILeiCE>>2298024The main 4 would be fine by me, I couldn't imagine using it much more than for POTA or something
>>2298012Check the reviews; the input in the latest is easily overloaded. You would need a broadcast band filter.
Just got a pair of uv5rs off amazon because they're a huge meme and everything. When they arrived I immediately noticed they're not brand name boafengs but instead something called "TIDRADIO". The weird part is they're visually and functionally IDENTICAL to baofeng models. Is there any negatives to using these offbrands, should I return them and get real ones? Does it matter?
>>2298238>bought Chinese trash>Received Chinese trash>Unsure about quality of Chinese trash>opinions about exchanging Chinese trash for the same Chinese trashIt's all garbage. It technically works, which is enough for the cheapskate, coping idiots.

>>2298439broadcast shortwave? because usually "shortwave" just means the shortwave broadcast bands, but it can also refer to the HF bands of ham radio as well. if you don't have a shortwave receiver, you can listen to a lot of broadcast shortwave on http://websdr.org and http://kiwisdr.com which both have a shit ton of SDRs hooked up to the internet where you can listen to both shortwave broadcast and ham radio stuff, among other things. https://priyom.org has a lot of info on number stations. https://short-wave.info has broadcast schedules for a lot of shortwave stations. the OP post that everyone else is directing you to also has a lot of good info. reviewbrah/report of the week has a lot of good info on buying shortwave receivers if you'd like to have your own. doesn't take much, just the receiver and a random bit of long wire hooked up to it. a lot of broadcast shortwave stations also still will send you QSL cards if you send them reception reports.
>>2298454That too. They are pretty much the same scenario, electrically speaking.
A guy at work gave me a 'noise blocker' he made - It appears to be a home depot plug with a capacitor running between live and neutral and a capacitor between neutral and ground. How's it supposed to work and is it going to explode or something when I plug it in? I cant even wrap my head around deliberately shorting everything out
>>2298606If the cap is sized right it will shunt some RF while blocking power. Common in the DC world but idk how to do it correctly with AC. You see it pretty often on TRIAC circuits and similar.
hey fellas, im going to have to switch from my 40m vertical to a longwire soon. going to use 55ft of wire and a 1:9 balun. is it going to be just as fine attaching the shield side to ground vs a counterpoise? and does it even matter if it's a few inches away from a grounded lightning arrestor? thx
Should I get a Yaesu VX-1000 for 20 eur?
>>2298798Or should I get a baofeng?
>>2292078Sir, sounds like you just need a Lab599.com TX-500 Discovery
>>2294063The wrongest and baddest and mistakenest thing is no Baofeng featuring APRS, SSTV and a few digital modes that don't require extra chips.Baofeng could literally throw in a cellphone camera and a display, some extra firmware, and sell a $25 UV6R sporting those things plus "take a pic and send SSTV image on the fly or a JPEG over the BBS packet radio".
>>2298902I do, I do...
>>2298805the vx-1000 is not as versatile as the baogfeng
serious question: Is there a cheaper and easier method for making a repeater than buying 2 baofeng and a cable?
serious question: do you really need a repeater if you aren't a hamfag trying to talk to other local hamfags over some shitty radio equipment?
>>2298967Yes. What if I'm just trying to organize some scouts in a large camp area with landscape that fucks up LOS? If I hang a repeater up on top of a bluff that oversees the area, suddenly all the walkie talkies work again, (provided they are on the appropriate frequency).This is a pretty low cost fix for the problem, and all it involves is someone hiking the repeater into position.
>>2290439>Or they destroy the unit, and OP is out the equipment. Even if OP has security cams, the likelihood he ever figures out who the guy is is extremely low.What if he does it in a castle doctrine state, has the unit on his own property, and lies in wait with a shotgun? Seems like it'd be a nice - and legal - way to kill some pompous boomers.
>>2298238>3800 mAh>muh metric superiorityWhy do people have to do that and not just say 3.8? Are we that dumbed down as a society to where that's a marketing technique for the masses? That's the best key feature to advertise?
>>2299072>Are we that dumbed down as a society to where that's a marketing technique for the masses?Yes, big number = sales
>>2299075I'm going to present our yearly sales in nano cents.
>>2299072if you've looked at enough schematics you may have noticed an annoying quirk of older US versions wherein they frequently replace the mu symbol with m or M. all three of which are orders of magnitude different in scale>inb4 it should be obviouswhy bother drawing the schematic to begin with?
>>2299097Most people write a lowwercase u for mu because fuck copy pasting greek shit those frenchies should have stuck to the roman alphabet but I've NEVER seen what you described
>>2298902why is all the cool shit so expensive
>>2299176Hobbies in a nutshell.
Is it even worth the cost for a handheld like a kenwood as a new HAM guy, or should I just get a bench model and dick around with handhelds after learning more?
cw is tough.Sending is hard enough, but training my ear is that much harder
>>2299269I'd recommend the path I accidently stumbled down.A Baofag uv-82hp on the ebay for $30.If you break it? Who cares. If you lose it or lose interest? Who cares.Learn frequency allocations, what's around you, how to program it with software, what a pl or offset is.If you're still interested, throw it in your glovebox in case you're bored or need help and get a real radio based on what you've learned and want to explore further.
>>2296923>Global warming is some fake gay hysteria reaction.It has been pushed so super hard lately because ( ( ( they ) ) ) know about the sunspot cycles and the fact that the Earth is entering another cooling phase.( ( ( they ) ) ) want to be able to say, "See, we told you that if you listened to us (and gave us all your eco-tax dollars) we would stop the global warming.
>>2298940Simplex/parrot repeaters are a thing. Only requires one radio and the repeater, which are about $40-$50.>>2298967In my case, yes. The homes we have emcomms with have shitty line-of-sight, which is worse for GMRS. The $400 for the repeater was worth it. One of the houses has a piece of shit drug addict son that OD'd. I had narcan available, so I was able to rush to the house before the ambulance arrived and saved his life. If we didn't have the repeater, it would have delayed treatment.
>>2299269Just stick to the tried and true Baofeng UV-5R's for awhile. They're great for learning the basics, and if you decide you don't want to stick to the hobby, you only wasted $30 instead of $100+.
>>2299025Pretty sure he'd still be fucked. There was a son and father who did that in a castle doctrine state after having been burglarized. They both got 1st degree murder iirc. Pretty telling that we live in a country where the state will actively refuse to help you, and then punish you for not being a victim.
>>2299421How long ago was that, I remember one where they were acquitted.
>>2298740update: threw up ~50 ft of wire with a counterpoise (ungrounded). made it to Arizona fine. guess it works!
>>2299511Checked and bassed.
>>2299436No idea. May have been a couple years or a decade, but my brain is retarded and time is extremely relative to my memory.
>>2299604I guess if it's like the above person suggested where you're baiting someone to invade your property with the intention that you can kill them instead of you legitimately fearing for life and property then i could see why it could be a murder charge.
>>2299404I guess as long as you have a spare adapter, you can connect even a UV-5R to any antenna you want?

http://www.southgatearc.org/news/2022/january/qst-magazine-looks-at-diversity-and-inclusion.htmi keep posting this shit, to show you dudes even ham radio isn't safe from the diversity nigger kikes.
>>2300143and if some of you don't know, we've already got a shit streeting nigger tranny as the ARRL hudson division chief, and all the mmmmBASSSED ham radio youtubers like josh nass are interacting with and promoting this freak. it's over ham bros. all the boomers are dying and now the communists, niggers, trannies, and kikes are invading. don't ever let them do this. call them out on the air, say the gamer word, become ungovernable, the boomers aren't going to save us.
I've been assuming the bands were shit for the past days, if not weeks.Turns out I was listening to a dummy load.
>>2300143There are 3 barrier to entries we can thank.Licenses (which includes a checkbox for felons), the cost of entry, and it takes more than 1 brain cell.Sadly, the gays could sneak in
>>2300167and that's the problem, the trannies. trannies have invaded every other interest, hobby, and career field that has anything to do with technology. now they're coming after ham radio. they've already got the ARRL talking about fucking pronouns and diversity. unironically death to all trannies.
>>2298238If you order a bull amount of radios from baofeng, you can customize the logo and model number, essentially rebranding it That's why these exist. They are the same shit. Go crazy, have fun
>>2300164Ah fug, well, some antennas are worth less
>>2300143>>2300167>>2300172It's largely self selecting, so it's nice. It will become tranny central though. Luckily OM and XYL havent become verboten. We've already got a tranny on some local repeaters. Somehow hasn't 41%ed yet though. Everyone knows it's packing Y chromosomes. No matter how bad you mutilate yourself, everyone will know as soon as you speak.
>>2300143>>2300172I don't mind them coming into the hobby. The thing I do mind is that they want us to start adding in pronouns when we say our callsigns. Ham should be an inclusive hobby, but it does not need that kind of bullshit. Callsign and name is all that is needed. And if they want to identify as female, they better sound female. We don't want any trannies that are putting off their voice training. If there are, I'm calling him a him.
>>2300348>an inclusive hobbyIt already is by not having this nonsense. This isn't about inclusivity, diversity or whatever fucking shitty ity is the flavor of the week. This is about power and this is about attention seeking faggots trying to inject their substitute for a personality into yet another sphere. See the CQ pride contest bullshit. They don't care about radio or contesting other than a means to draw attention to their perversions, which you better tolerate, bigot.
>>2300377Digits of truth right there, anon.
I don't get why UHF is so inconsistent. Some nights I can hear stuff that's 3 or 4 miles away with my UV-5R. Other nights, like tonight, I can barely hear stuff going on 1000 feet away. What makes the difference over such short ranges?
>>2300429UHF can be heavily affected by wet leaves -- does it correlate to weather? Even then, I would expect more than 1000 feet unless you're in a location with marginal line of sight.
>>2299442блин. бpaт, oткyдa ты этo нaшёл?
>>2300444o shit self-check / wasted digits!
>>2300444Clear skies tonight, winter trees with no leaves. It's not a super great line of sight, but it's 1000 feet from me to the railroad (with some houses in the way) and I like to listen to the track workers when they're out. An hour ago I could barely hear them, now they're coming in clear. Just my chinese garbage radio, maybe? I'm about ready to look into getting a real scanner. the UV-5R has been a great cheap thing to play with and learn the basics. Sadly all the fire and police departments around me are going to Project 25 and/or other digital modes and I don't know much about that.
>>2300451Hmm. You can expect to have some level of variation when going handheld-to-handheld. Especially if they are working around big metal train cars and maybe not holding their radios very steady or close enough to their mouths.Before replacing the radio I would look first to the antenna. Set up a proper antenna as high as you can reasonably get it and see if your reception gets more consistent. Or, if it gets worse with a better antenna, you are getting desense from another noise source and might need a better radio. But that isn't so common on the UHF band.
>>2300468>Before replacing the radio I would look first to the antenna.I do plan to. I've noticed when walking by the workers trucks sometimes that they're picking up stuff I'm not even hearing as static, probably a big reason is because they have bigger antennas. Where I'd definitely want a better radio is for scanning. Both to scan faster and to be able to receive digital transmissions where possible. The UV-5R is definitely weird about the squelch, though. and yes, I've tweaked the squelch settings in Chirp and did make it a little better.
>>2300476For sure, a dedicated scanner or a nicer ham radio makes for a much more pleasant scanning experience.Trains can be very long, so it is also be possible that some workers are simply much farther away than you expect.In my experience I installed a simple UHF 1/4 wave ground plane antenna near the ceiling of my apartment and that got me +3db of signal versus just holding the radio as steady as I could. Plus it eliminated all the natural variation from me moving around or placing the radio in different locations. Not a bad way to go if you do a lot of UHF.
>>2300445On 4625 kHz USB the other night.
>>2300451Try a new antenna first. UHF is like that. Don't cheap out on the cable from the radio to the antenna and only buy as much as you need.A moxon antenna is pretty easy/cheap to build if you want to experiment. Moxons are directional, have decent gain, and have wider lobes than a yagi-uda. P25...two (or more) sdr dongles and sdrtrunk will let you listen in on unencrypted stuff. it's fun to experiment with if you have the dongles laying around but a scanner ought to be superior. Save that money and put it towards a proper scanner.
>>2300682>moxon antennaI had never heard of that. Very cool. Now I sort of want one!
