Exchange several messages to get a feel for this new mode. If you monitor the
radio transmit indicators and listen to the speaker audio from the two rigs, you

the time, even while you are actually typing. When you get to the end of a line
and type a <CR>, your radio will be keyed briefly and your friend will hear a
