Here's an earlier test from me:
Radio reception in DSB-demodulation with 500 Hz frequency offset. This 
generates a offset of 1 kHz.between LSB + USB-data in the audio spectrum .
This means:   no destructive overlap with MFSK-32
You can save together in one mono audio file hereby USB + LSB Data.    
This only works with sufficient narrow modes.
