I've seen a lot of these $50 devices lately and I'm wondering if they
would be compatible with GnuRadio...
No support currently. Not likely.
Anyone ever used one, and/or know how they operate? Hopefully they're
just a front-end with a ADC that sends I/Q to the CPU for
processing....
:-) Silicon Labs makes one chipset used in some. It has a 8051
microcontroller and a FM Tuner chip. I think all those chips output
Left/Right audio, not I/Q.
