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.
In the AM mode, you can transmit on only the
HF/50MHz frequency bands.

• Speak into the microphone at your normal voice level.

In the SSB mode:
Hold down [ANT•METER] for 1 second to select the
ALC meter. And then, while speaking into the mi-
crophone, rotate [MIC GAIN] so that the ALC meter
reading stays within the ALC zone.
In the AM, FM and DV modes:
While speaking into the microphone, rotate
[MIC GAIN] with another station listening to your
voice for clarity.

NOTE:
When you transmit on the HF/50 MHz fre-
quency bands, while monitoring an out of the ama-
teur band frequency on VHF or UHF on the SUB
band, the squelch on the SUB Band closes. There-
fore, you cannot receive on the VHF or UHF fre-
quency.
