Totally possible. A subtone in your F1 (CQ memory) , some added logic to the 
soft used for CW skimmer....
CW Skimmer would  become AnyMode Skimmer.

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 
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 ...  73, Dave   AB7E
