[CQ-Contest] Online marketing spotting

Hi, Pete.

Those are all valid comments ... for today.

I think it might be possible, however, to overlay a voice signal with 
some sort of lower-volume digital encoding that a Skimmer-like 
application could decode, possibly with more reliability than for CW if 
the proper encoding scheme was chosen.  I'm no expert on the digital 
modes, but I believe that some of them are rather remarkable in terms of 
intelligibility in the face of interference ... especially when they 
have voice-wide bandwidths to work with.  Anyone could rather easily 
generate the combined voice/signature files for use as voice macros, and 
of course receivers could be adapted for whatever target band segment 
was desired.

It remains to be seen whether such a scheme would be considered legal, 
though, even if someone only used such a digital overlay when 
transmitting and didn't user a decoder to receive callsign information.  
If I transmit a digital signal that allows the guy on the other end to 
decode my callsign, would I be violating the rules prohibiting 
cross-mode-contacts?  I strongly suspect I would, but who knows what 
future evolution of the rules might occur for assisted categories.

Just some thoughts ...
