Hi Bill,

trunk.csv isn't required for conventional. Here's a few exmaple commands I
have used with my USRPs (via UHD) and airspy:-

../rx.py -S 2500000 -o 50000 -q 2 -f 434075000 --args 'uhd' -D fsk4 -P fft
--gains 'PGA:10'

../rx.py -S 1000000 -o 50000 -q 39 -f 434075000 --args 'uhd' --gains 'PGA:40'

../rx.py -S 2500000 -o 50000 -q 2 -f 438187500 --args 'airspy' -D fsk4 -P
fft --gains 'MIX:5'

 /rx.py -S 1000000 -o 50000 -q 2 -f 438187500 --args 'uhd' -D fsk4 -P fft
--gains 'PGA:30'

Cheers,
Matt
