Re: [Discuss-gnuradio] Issue with basic FM receiver

Hi Marcus,

Thank you for your reply. The Frequency Xlating FIR filter should be already doing the decimation to being samp_rate down to 48k.

However I found out that formula for the Quadrature Demod gain was using samp_rate instead of audio_rate (48k) and the gain was excessively high.

Having fixed that, now it works.

Thank you,

Ludovico
