Here are some pointers for you:
- Firstly, your screenshot shows the error message saying that the RX
frequency is not valid. I’d recommend using a WBX daughterboard, however
the BasicRX should still work with strong FM signals with aliasing if
is what you are using.
- The samp_rate is set to 100e3. It should be the master clock rate of
e110 divided by an even number such as 64e6/256 (250e3).
- The quadrature rate in the WBFM receive block should be set to
(250e3) and the Audio decimation should be set to 5.
- The audio sink sample rate should be set to samp_rate/audio_decim
(250e3/5=50e3). 50e3 is as close to the wanted audio sample rate of 48e3
that you are going to get without using one of the resampler blocks.
