Here with Perseus SDR the 100Hz sidebands are decoded between -37dBc and -41dBc 
(below the shifted
carrier) if the SNR exceeds +11dB.
Maximum SNR was +27dB with Perseus RX (and +31 with the Reuter Pocket RX 
[DL4RAJ/2] ).

For comparison:
PA0A was peaking here within the last two weeks up to +18dB SNR
with no detectable sidebands at all.
