OK -- someone mentioned LNAT. So what DOES that stand for? ....

Thank you Loren, but I'm still confused. You are correct in what I am trying to do -- just decode that SDR narrow band FM signal directly -- but from my understanding of how SCA is encoded, that should work. I don't understand how what you are suggesting different from just decoding from the baseban...

Update -- I can SEE the SCA signal, and the problem seems to be that the main carrier modulation 'overwhelms' the sub carrier. Is there a way to 'deemphasize' the off channel modulation (a 'band pass filter' essentially) or at least modify the receiver so that it will DEemphasize off channel signals...

I am an old hand at 'radio' but SDRs are new to me so bear with me on this please! I have a 'local' FM that uses a 67 kHz SCA and tried to decode that using SDRPlay and the 'included' CubicSDR (OSX) and it appears there is not sufficient 'separation' from the main FM modulation to allow the decode t...
