Looking for #recommendations for #usb #wideband #radio #receiver please. Interested in #VLF up to a few #GHz, mostly want to hear #sferics, #hamradio, #shortwave, #solar, #jovian and any curiosities besides.
Would one single #SDR receiver span all that comfortably? Could it be used with some sort of computer visualisation software to watch the passband go by over time?
Got my #RSGB M-class callsign over 20 years ago, now curious about RF again :)

24 December 2025: The Very Low Frequency (VLF) transmitter from Grimeton (Sweden) with the call sign SAQ goes on air. Is it possible to receive this transmitter with simple means in the city of Bern? Yes, it is possible.
Antenna: (DIY) three ferrite rods wound with HF litz wire.
DIY up-converter.
Degen DE1103 receiver.
The signal was weak, but it was still possible to copy it. -
