Luke KR4CYF#HamRadio Waterfall design question: on the #sbitx the past waterfall lines don't move with the vfo (centerline) so scanning/tuning around smears the waterfall to what seems to me much less utility. (history gaps with tuning outside the span, sure). I got used to the #airspy sdr computer display where the span can be all of the band you're interested and tuning moves the line (not fixes center). What do other radios do, I don't see folks complaining about this UI choice so maybe it's expected?
London Shortwave🎙️ One-two, one-two, is this thing on? It’s been a minute! Late to the party but here’s uConsole CM4 running CubicSDR with #AirSpy HF+ Discovery.

My haul over the last 12 hours (early evening to morning)
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.

Kind of extreme DXing... (Assumed) Bolshevik music is being rebroadcast via one of the US Milsats on 253.860 MHz NFM. The transmission could be being uplinked from almost anywhere in the satellite's footprint.
The fun part? I'm hearing it using an Airspy HF+ Discovery and a standard Airspy Youloop, with no amplification!

A salutary tale
I thought I'd taken precautions by depowering and unplugging my SDRs before transmitting at around 50W on HF the other day, but I appear to have fried the input of my Airspy Discovery HF+!
In the vain hope that reinstalling the firmware might help, I tried to reset it and flash the device but it could not be found on the USB input.
So it's now also bricked! This was the most sensitive little HF SDR I had, so none too happy today 😭
SDR Firmware
I just spent three hours trying to flash update my Airspy HF+ Discovery. Followed the instruction to the letter but failed every time. 😭
I later found that the Airspys can only be flashed from a Windows 10 machine, not Windows 11! Luckily my older second PC is still on Windows 10, so I was able to un-brick it! So happy now! 🙂
The PiZero 2W spectrum recorder runs for 7 hours on two 18650s & a step-down 5V converter (which doesn’t seem to add measurable noise on HF). And of course the batteries are hot-swappable as the unit has its own small UPS battery. The only limitation is the amount of free space on the MicroSD card 📡#PortableSDR #SDR #HF #Shortwave #SpectrumCapture #SpectrumRecording #AirSpy
