i bought one of these HackRF units about two years ago after reading a bunch about the guy who made it and some of the videos he made. the maths go whoosh over my head though
https://cdn.sparkfun.com//assets/parts/9/9/5/3/13001-01.jpg

i toyed around picking up the FM band and was trying to find the ems channels to listen into but i just don't know enough about it. the waterfall graph is super pretty to watch though

are there other resources that any of you know to start messing around with it more
and i guess my other question is could i use something like this for like a home automation thing? maybe send signals to devices that use RF?

Jr pushed me over the edge and today I spent an hour fiddling with my shortwave radio with an extended antenna. The extended bit is a drain pipe on my apartment building.

edit: Drainpipe radio is currently bringing me some weird russian radio, and a ton of north african stations

idk how you mega nerds have done it but im finally
concede that the EM spectrum beyond visible light probably exists and make the first moves toward reviving radio signals with my metal teeth.

careful not to listen too much to chinese radio , you might get activated

this lovely video popped into my youtube feed and it contains all sorts of goodies that everyone should try: listening to satellite communication and looking at what planes above you are squawking.

also contains: don't ever do this or its forever-jail for you. Turns out it's incredibly easy to ddos flight control radio. One moment, normal traffic, next a wall to wall carpet of planes all heading for the control tower.

when you say ddos do you mean dos? bc it seems hard to run a bunch of radios all doing the thing at once

obv i haven't watched the video yet or id know the answer

it’s not actually dos, but more creating an army of ghost planes

favorite example of the speaker is generating a ghost plane that’ll fly directly through traffic control, but they can’t know it’s a ghost plane so they will evacuate

needless to say, forever jail

Have any of you lovely hams found a handheld transceiver with a dial or knob for going through presets / scrolling through the frequencies?

I managed today with little incident to get dump1090 working on my m1 macbook. Can't wait to go to the airport and get weird glances

awesome, thank you! that also helps clarify some questions i have/had around "how the gently caress do i attach this to the roof without messing up my chimney"

my neighborhood, the only one in Copenhagen filled with hams, is any indication you build a huge steel structure next to your house to put your antenna on

in the US there's an FCC rule that you're allowed to build whatever tower you want on your own property for the purposes of amateur radio, and you get to ignore local regulations to the contrary.

every few years ARRL tries to get Congress pass a bill that allows people to also ignore HOA regs but it never goes anywhere

Does federal law not supersede your local hoa?
