FUNCTIONS FOR TRANSMIT

N Break-in function

The break-in function is used in CW mode to auto-
matically switch the transceiver between transmit and 
receive when keying. The IC-7200 is capable of full 
break-in or semi break-in. Break-in operation is also 
referred to as QSK.

D Semi break-in operation

During semi break-in operation, the transceiver im-
mediately transmits when keying, then automati-
cally returns to receive after a pre-set delay time has 
passed from when you stop keying. This is similiar to 
VOX operation for voice.
