A modest annoyance with my current #Debian and #KDEPlasma6 setup: the #AmateurRadio apps change to the default audio source when the computer wakes up, rather than the otherwise unused motherboard audio I have configured.

So if #gqrx and #wsjtx are running when the PC goes to sleep, it will resume upon waking--but via my main audio interface. I have to manually change it and change it back for it to work properly again.

(I don't actually want #ft8 tones through my studio monitors.)

Things are a good deal more active now

#AmateurRadio #FT8 #wsjtx #gqrx

GQRX screen shot showing a very active portion of the 17m HF radio band.  There are many little colored caterpillar-looking things in the waterfall display, each representing an FT8 digital transmission for about 13 seconds.Map of most of the western hemisphere, showing dozens and dozens of contacts across North America and a handful from South America and Europe.

20m is doing brisk FT8 business this morning.

#AmateurRadio #FT8 #wsjtx #gqrx

screen cap from GQRX showing a waterfall display and spectrum. There are many 13-second transmit sequences shown in the waterfall, narrowly spaced, indicating lots of transmitters operating in a narrow slice of bandwidth.

*taptaptap* Is this thing even on?

That's a stupidly low noise floor on 17m this morning. #FT8 coming through just fine from up and down the east coast (about 650-900 miles away) (so far)

#AmateurRadio #gqrx

screen capture from gqrx, a software-defined radio control program, showing a spectrum and waterfall. The noise floor is at about -120 dB, which is very very low. You can see a few spikes of noise above the floor, and also a handful of actual signals in a shaded area of the spectrum around 18.1 MHz where the FT8 protocol is active.

My take over the last 24 hours using an #AirSpy DiscoveryHF+ receiver and a YouLoop magnetic loop antenna mounted to the wall of my apartment.

Mostly 20, 10, and 40 meters.

#gqrx is not quite as polished as #SDRsharp on Windows but it reads my Discover HF+ just fine, and can be controlled by #WSJTX. It took me a while to get the settings right.

And unfortunately it's set up right now using my nice studio audio interface to pipe audio from one to the other. Once I switch it to something else, I can have this decoding full time in the background and still play games and do music and whatnot.

@electragician be warned: rabbit hole ahead. Have fun.

You might want to have a look at #SDRPlusPlus. I find it easier to use and more pleasant to look at than #gqrx.

Also have a look ad #SDRAngel. That has some handing tools inbuilt to decode packet/aprs, adsb and many other digital signals.

Oh man, I feel a new hobby coming on.

I picked up a RTL-SDR V4 a few days ago, and I’ve been exploring the radio spectrum with the antennas that came with it. Software defined radios are pretty fun!

I may have contacted the local amateur radio club today, and I may have also ordered the study guides to get me all the way through my General Class License.

Someone / something is (intentionally?) jamming the whole #ISM433 band, and consequently, the #70cm #hamradio band.

That's horrendous and totally illegal.
