>>32676311
if you passed the test then it should be no problem. Otherwise turn it on, pick the local repeater and Lurk More.

I plan on aquiring one of these in the future and would like to see how /k/ utilizes them.

>>32676311
No.

If you don't already know then you're not worth the airwaves. Find a new hobby.

>>32678462
You first. And don't even think about even turning your radio equipment on before getting the proper licensing and learning more code. I can track down your signal and personally send the FBI to arrest you.

>>32678533
Woah, watch out! SOT-A Johnny's gonna backtrack ya!

How about some constructive advice for OP? OP, get yourself a basic HAM operator's manual and find a testing location on the ARRL website. Shit is cheap and relatively easy. Baochangs will be simple when you get a little more knowledgeable on the subject.

>>32678595
You can find the ARRL books on bit-torrent.

In short, broadcasting on most frequencies is for-realsies illegal, broadcasting on walkie talkie frequencies (FRS, GMRS) is sorta illegal (your baofeng not having type certification).

>>32678533
You no longer need to know morse code to get a license, faggot.

>>32676311
Pay no attention to the manual. It's worthless.
You'll need a programming cable to put memories on the radio, they're like $10 and the software is free. For programming, look up CHIRP, and you'll find guides for your radio.
You can get common memories like NOAA weather reports, FRS/GMRS, and marine channels from CHIRP itself, for other shit you can look up ham radio clubs in your area or check out radioreference.

To triangulate, yes. But most of the time a signal meter will get the job done. People aren't very good at hiding and are usually obvious.

No you fucking can't you fucking pretentious faggots.
Your neighbor not being able to catch the game on the old tele isn't "fucking shit up" and the equipment you use is fucking pitiful. This is "cell phones interfere with the navigation of planes" tier.

>>32681065
Yeah, but given how shitty baofengs are with spurious emission, it is a tad bit of a concern. It's more the FCC not doing its job and regulating the radio though.

>>32681068
You can do it with just one and moving around, you don't necessarily need multiple stations for triangulation.

Watch out, we've got a badass over here. Almost 1/15 the power of a fucking hair dryer, wouldn't want that sort of equipment getting into the wrong hands.

>>32681150
That's nice, Anon. Anything that's not HF is a meme band and that's all there is to it.

Also, guess what microwaves are? Radiation in the ELECTROmagnetic spectrum. Max output in 'murica is theoretically 1800 watts assuming I don't get to use my own power supplies. Now, wikipedia tells me microwaves can operate at around 70% efficiency, so that's 1260 watts of EM output. Now, conveniently magnetrons operate on DC current so we can use pulse width modulation to vary the power output and use change in the duty cycle to transmit data, i.e. communication. So yes, my microwave is in fact more powerful than your baofeng, and probably all of the equipment you own.

Now how could the American government let such dangerous equipment

You really shouldn't fuck with these unless you know what you are doing. There's a reason ham radios have classes, certifications, and callsigns and shit.
It's a pretty simple to use device if you know what frequencies and shit you want to use.

There are a few youtube videos on how to turn them into more powerful walkie talkies.

Is there any way to set these up for data transmission?

They have a speaker port, and 3.5mm used to be used for data transfer. I'm aware that encryption is illegal over radio, but I'm thinking more for just using one as a simple modem.

>>32678533
Every time I see radio related shit in catalogue I just know this faggot's gonna show up and pollute it.

>>32683761

Almost every telemetry and iot system is encrypted nowadays.
Stick to ism frequencies and you'll be fine.

These use american-made chips and are ridiculously cheap for rf modems.
I ordered about 50 things from them so far and not a single technical problem.

Everything above 0.5W is technically illegal,but I've been using 5W gfsk modems for years now and nobody gives a shit.

>>32680973
This trip knows.

Get the USB cable, get CHIRP, know what version of firmware you have, program channels and features, fuck the FCC and piss off the old-timers (they like a good foxhunt as long as it's before the evening news), keep in bug out bag for emergency comms.

True story, I used mine last month for a multi state trip to Kansas. Shadow car had a shitty store bought family radio. We got back and he bought a Baofeng for the next run. We travel down south to pick up cars probably every couple months

There's a really good soundcard program called "fldigi". You should also get a soundcard interface (you can get those on ebay- I think they call them "easydigi" interfaces).

>implying there's anything better than a thumb detecting nut fucker
Baofengs aren't really suited for data transmission. In general, the only type of data that's done over FM is AFSK (audio frequency shift keying) which is a rather inefficient method of data transfer. The only type of data sent this way is APRS (automatic packet reporting system [automated GPS and telemetry shit used by hams]).

Generally, for any type of reliable data transmission, people use FSK (frequency shift keying), or one of its many derivatives. This type of things requires a specific radio, and can't be done from a general purpose FM radio.

>>32684684
Cool! Would be perfect for all sorts of shit. What are you using them with? I've got some data logging applications where this would be great. Is it relatively plug and play for basic TTL serial?

I mainly use them to make jammers, but I recently started working on an encrypted radio.
I use the ttl version. You program the modems with a dongle you get for free.
