Hi,
RXing with the USRP simply doesn't work, though, neither with usrp_rx_nogui.py
nor with anything I could come up with. I get lots more noise than expected
and usually I get a very loud buzz or whistle which is a lot louder than the
TXed signal. Has anyone else had this problem?
I'm using the Basic* boards directly connected to an antenna (no bandpass
filtering).
Hello Martin!
The BasicRX has no aliasing filter. You get a lot of mirrored
frequencies from above 30MHz. It is possible to receive FM Radio...
Check your selected frequency for mirror-frequencies from the UKW-Range.
Maybe you can use FM demodulation to identify a interferring FM radio
station. Just a guess.
