License requirements depends on the country, in some it is OK if the emitted power is low.

So do I have to post a picture of my nonexistent license for you to believe it? Not that I care about a hamjanny's opinion, though.

>>2472477
Ah yes clearly a healthy lifestyle.

This is NI6GER, looking for a radio check.

That they do, I'm in my local ham clubs mailing list and they were just arguing about the proper usage of the clubs mobile tower.

why would you say your real callsign

>>2472504
Based illegal radio operator chad, your chink radio is all the license you need.

>>2472350
I don't like how much control amazon has over the market, or how they treat their employees. If you hate Big Businessᵀᴹ then you shouldn't like amazon. Even if they are convenient.

Okay maybe retard tier question: I have a BF-F8HP in the mail and I’m trying to get into ham radio. Are there any good directional antennas for baofengs so that you can triangulate broadcasts? I’m mainly interested in ham radio for the SIGINT

>angry boomer at it again

>>2472813
Look up the tape measure antenna. It's easy to make, and it's very cheap compared to buying a yagi.

>>2472821
Is that something you can hook up to the Baofeng easily? I’ve seen someone with a PVC and tape measure do “fox hunting”, that’s the triangulation ham people do for fun right?

>>2472821
This, I have the ABBREE 18.9 incher from amazon and the thing is so sick at not only 146.520 simplex, but UHF and illegal GMRS usage on my BF-F8HP, it just resonates decently at everything, I had even switched to the Nagoya NA-771, thinking it would be a game changer, and it wasn't, the ABBREE was just very very decent at everything.

>>2472799
I think other business need to git fucking good, there's small restaurants in my town that I frequent because they're so damn good for the money, despite not being a chain and I drive 2 miles to get there, and that's what Amazon is, it's damn good for the money.

>>2472504
You have a TYT 9800? Can you gib pics of the rear panel? I'm trying to source radios for high speed packet shit that have access to flat audio, and if this radio can do it easily, it would be the money shot.

>>2472952
Not him, the TYT9800 has a USB-C port and a 3.5mm stereo out that switches off the internal speaker when jacked in.

>>2472821
Easy and cheap, but certainly not directional.

>>2473014
like that maybe

>>2472952
Not the guy you are talking to, but I got the D version of it. I haven't tinkered with it as I bought it off someone in the club two years ago when I passed the Tech test, and it's been in my vehicle since. All I did was program the local repeaters, GMRS, MURS, and CB. There's no mention in the manual about data modes with it. Here's the back of it. My next post will be the data port used to program it.

>>2472952
>>2473038
And the data port close-up

And label just because I want to.

>>2473054
Wrong car. Only my set up is this messy and a fire hazard!

>>2473238
Are you me?

>>2473251
No, you are me. Get out of my head.

Lose some weight, you fatfucks. Get out of your mother's basement and do a SOTA activation.

>>2473472
>Fat people with radios on mountains
I can see that ending well.

>>2473485
the ones who do that aren't fat

>>2473487
Not all of them.
pic related, had to hike 3600 ft higher to mount this antenna that I hadn't tested before

Guys this could be a stupid question. If i get a ham license. Will people be able to look up my gamer tag and see where i live and stuff like that? HAM's are public record right? Or am i mistaken?

>>2473530
>gamer tag
kys

>>2473530
in the US, it seems so, elsewhere, depends on the country

I noticed using scramblers, codes and even real digital encryption is common for fishing vessels. What do US laws say about it?

>>2473555

I dont want to read hundreds of pages of regulations for something that can be said in a single sentence. .

what SDR software do you guys recommend for linux? I'm trying to get anything working with gentoo right now (cubicsdr, sdr++, gqrx...) and I'm having a hell of a time with all of them

>>2473530
Yes. However you can just use PO box instead of your home address.

>>2474240
I recommend getting a separate airgapped computer with windows for compatibility reasons. You will not regret it.
then HDSDR

Imagine how lit the GMRS channels and simplex freq are in FL right now.

Resources for learning about DSP? I want to get into GNU Radio and SDR and stuff but I don't know half of what they are talking about.
>wtf is quadrature rate
>wtf is decimation
>wtf is sample rate
>wtf is a low pass filter
>wtf is a rational resampler
Do I need a fucking physics degree or is it possible to learn this at home without sacrificing a whole lot of time?

>>2474240
I like GQRX for listening, but for TX/RX I just use SDRAngel. Slightly worse GUI but I can actually transmit.

>>2474452
>Imagine how lit the GMRS channels and simplex freq are in FL right now.
I'm sure every other family handed their screaming 3-year-old a Walmart radio in order to distract them from the fact that their iPad has run out of battery.

>>2474751

Plenty.

I ama physicist by training and did some DSP work a while ago, but mostly this is EE type work. BTW the library mentioned in the OP text has some DSP related documents.

>>2474768
Thank you anon. BTW I'm shit at math, I barely graduated HS mathematics, am I fucked?

How do I mount an antenna on a sloped roof without drilling holes in it?

>>2474773
Doing DSP work without feeling comfortable about maths will be painful. You really want to understand FFT and related transforms. Hilbert transforms are also used.

You can also learn by picking apart existing projects, some are mentioned in the FAQ.
As for work, you can make a nice, well paid career in DSP work if you know your stuff, see >>>/sci/scg and the FAQ for that general.

Pain.

>>2475401
Do you have a backup cellphone? The Aurora Group are great when it comes to allowing workarounds.

>>2472504
Another good one is just say your license is the US Constitution.

>>2475504
That's what's up, Anon I always bust their balls by saying shit like

I've been told this for years, and I hear people say it on the scanners, but come on. Do people set up automatic triangulation for every single frequency and station?
