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 rst,
and then, even if nothing is heard, ask “Is the fre-
quency in use?” once or twice, before you begin
operating on that frequency.
Transmitting D
CAUTION: Transmitting without an antenna may
damage the transceiver.
In the AM mode, you can transmit on only the HF,
50/70* MHz frequency bands.
* 70 MHz band transmission is available, depending on the
transceiver version.
