Once upon a time they called that 'coherent' cw. I started looking into 
it and saw the dreadful results. I wrote it off as quite impractical 
away back then. It was not only terribly slow but relied on somebody 
else's transmitter, not even the other ham, to make the whole thing 
work. Like the gps 'disciplined' timebases used for that nonsense today. 
Sure it gets some kind of results. But none that are actually useful - 
beyond amusing some radio experimenters. They have been experimenting 
for quite a while now and it hasn't improved any. I'm hoping they'll get 
it to the point of useable but it isn't looking good. They really do 
have to transmit all night and all they get across is their ID and maybe 
their location.

When I want to order a pizza I would like to have it today.

73,
