[CW] SOS SOS SOS CQ de WOOH - Marine Electric

[Ken Brown]

Hi David,

Thanks for posting that recording. I have a few questions about it. Are 
those signals A2, or MCW? The audio tone frequencies of the signals do 
not seem as stable as amateur CW signals of the same era. Is this due to 
instability of the audio oscillator in the MCW transmitters? Or if it is 
A1, CW is it instability of the RF oscillator in the transmitters? Or 
the LO or BFO in the receiver? Or is it a regenerative receiver?

Thanks,

Ken N6KB
