I've observed the following with the latest FastLane FMP24 v2.8 dated 2016-05-16, using a NooElec 0.5PPM R820T SDR and the command-line:
FMP24 -i2 -o20001 -P0.5 -g36.4 -b12.5 -f772.00625 -v10 -a1 -t1 -rc
The -b option doesn't seem to work.
1. If I specify -b9.5 or -b12.5, it recognizes the option (i.e. it says " 9.50 kHz RF bandpass filter selected") but it opens up with the bandwidth set to 7.6.
2. If I specify -b7, after spitting out the decoded options, it just hangs without starting the spectrum display, requiring Ctrl-C to kill it (not <escape>).
3. -h says the value is 7, not 7.6. If I specify -b7.6, it complains "invalid command-line parameter: '-b7.6'", as it does for any other invalid value.
