BASIC OPERATION

■ Basic transmit operation

Before transmitting, monitor your selected oper-
ating frequency to make sure transmitting won't
cause interference to other stations on the same
frequency.

D Setting the Output power and Microphone gain
If a linear amplifier is connected, such as the IC-
PW1/EURO, set the output power using the ALC
meter to the ALC zone (see "Microphone gain set-
ting" below.) The ALC meter reading should be
within this zone, otherwise the linear amplifier will
not work properly.

It's good Amateur practice to listen first. On the
HF bands, even if nothing is heard, ask "is the fre-
quency in use" once or twice, before you begin
operating on that frequency.
