Wow, sounds good, I've got a bunch of 50KW stations about 2 miles away
and I cannot get any to sound good at all. What receiver code are you
using?

The code that I put on on CGRAN yesterday:

And the supporting RDS code:

I'm using a TVRX2 on a B100, and this was with 8-bit baseband samples at 320Ksps input rate to the FM demod.

Your problem might actually be that you have a *bunch* of 50KW stations close by.   Although with 70+ dB of dynamic range
  even at 12-bit ADC sampling, with the gain set right, you shouldn't have too many problems.
