I just downloaded the RelWithDebInfo precompiled windows software that was
posted on Oct 24th. I am using an E4000 dongle which has a PPM of +30.
I am trying to listen to 424.175MHz and I'm using this:
rtl_fm -p 30 -d 1 -N -o 4 -f 424.175M -s 16k -C|sox -r 16000 -t .raw -e
signed-integer -b 16 -c 1 -V1 - -d
everything is playing fine. I can hear 424.175MHz. The issue is that I'm
hearing another station 50KHz higher on 424.225Mhz in addition to the
frequency I want. So it looks as if it's not using a 16Khz filter. Am I
doing something wrong or is there an issue with rtl_fm.exe? Thanks
