Can anyone recommend, from personal experience only please, a webSDR hat that absolutely 100% worked on their Raspberry Pi 4, more-or-less out of the box? Please also include (1) the OS version you’re running (2) The software version, and (3) whether you had to change operating systems or not in order to make it work.
My Pi 4 is running the latest version of Raspberry Pi OS.
I’m interested in HF mainly, but I’d also appreciate answers for VHF.
Thanks in advance!
