It is possible to actually interleave CW, so momentary word pauses allow a 
window for other transmitters. The multiple frequency recorded data needs to 
be in actual true time on all frequencies if we look for simultaneous 

While I abandoned this idea for a while because of interface issues with 
computer logging software and operators, I had a box built that stored the 
CW and watched for three-dot or longer "word pauses". The box could "hold" 
CW coming in and insert short bursts in word pauses by increasing word 

Like this:
1 W8XX
2 k4aa
1 599
2 599
1 ga
2 ga
1 tu
2 agn?


>From a few experiments, I'm sure that is workable technology. The only 
problems were logging software did not allow an external hold to prevent 
rehitting a send while a transmitter was held off, and the operator 
interface for knowing and cancelling a held send.

Recording two channels in a single stereo recording works, but I'm not sure 
what else does. The first thing is we should know how the data collection 
system works, and I only know how a two channel stereo system would work.
