When I start vdlm2dec this way: /home/pi/vdlm2dec/vdlm2dec -v 2 -r 11 -p -1 136.725 136.775 136.825 136.875 136.975 -l "/home/pi/vdlm2dec/logs/vdl2_rtlsdr-11.log" >> "/home/pi/vdlm2dec/logs/process-vdlm2dec.log" 2>&1 &

The program starts and works as expected but gives 4 warnings: Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000011

Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Tuner gain : 49.600000 WARNING: Invalid frequency 0 WARNING: Invalid frequency -1000000 WARNING: Invalid frequency 0 WARNING: Invalid frequency 0 Set center freq. to 137025000Hz Exact sample rate is: 2000000.052982 Hz

2 of the warnings go away when I remove the "-p -1" part like this: /home/pi/vdlm2dec/vdlm2dec -v 2 -r 11 136.725 136.775 136.825 136.875 136.975 -l "/home/pi/vdlm2dec/logs/vdl2_rtlsdr-11.log" >> "/home/pi/vdlm2dec/logs/process-vdlm2dec.log" 2>&1 &

All warnings go away if the arguments are move to another place like this: /home/pi/vdlm2dec/vdlm2dec -v 2 -l "/home/pi/vdlm2dec/logs/vdl2_rtlsdr-11.log" -p -1 -r 00000011 136.725 136.775 136.825 136.875 136.975 >> "/home/pi/vdlm2dec/logs/process-vdlm2dec.log" 2>&1 &

Cheers, Dick

Yes, it's not clear in the doc, but frequencies must be last. ie :

/home/pi/vdlm2dec/vdlm2dec -v 2 -r 11 -p -1 -l "/home/pi/vdlm2dec/logs/vdl2_rtlsdr-11.log" 136.725 136.775 136.825 136.875 136.975 >> "/home/pi/vdlm2dec/logs/process-vdlm2dec.log" 2>&1 &
