R WARNING:
Set the transceiver output power and linear amplifier
ALC output level referring to the linear amplifier in-
struction manual.
The ALC input level must be in the range 0 V to –4 V,
and the transceiver does not accept positive voltage.
Non-matched ALC and RF power settings could cause
a fire or ruin the linear amplifier.
The specifications for the SEND relay are 16 V DC
0.5 A. If this level is exceeded, a large external relay
must be used.
