Basic transmit operation
Before transmitting, monitor the operating fre-
quency to make sure transmitting won’t cause
interference to other stations on the same fre-
quency. It’s good amateur practice to listen first,
and then, even if nothing is heard, ask “Is the fre-
quency in use?” once or twice, before you begin
operating on that frequency.

CAUTION:
Transmitting without an antenna may
damage the transceiver.
