Hello,
I have created FM transmitter in GRC:

Unfortunately demodulated audio has poor quality and annoying
distortions. I have spent a lot of time on it without positive effect.
Here is how demodulated audio sounds like:

When I have created FM receiver in GRC (bottom part of the schematic),
demodulated audio sounds perfectly on my PC.
Any ideas?
I'm using gnuradio3.3.0 + USRP2(with interpolation changed from 4 to
2) + BasicTX + FT857D as hardware receiver.
