Yep, about half of the callsign of stations calling you, which means repeats, 
slowing down.
You either operate with QSK and torture and burn the relays, or semi QSK with 
delays and miss calls and exchanges. With PTT controlled by the computer, you 
save relays, and have precise timing and save equipment, as it was said, for 
few cents, perhaps cost of piece of wire going to PTT on the mike connector. 
Just watch contester running at 8 QSOs a minute and you will get the picture.
