R WARNING:
Set the transceiver output power
and linear amplifier ALC output
level referring to the linear ampli-
fier instruction manual.
The ALC input level must be in the
range 0 V to –4 V, and the trans-
ceiver does not accept positive
voltage. Non-matched ALC and
RF power settings could cause a
fire or ruin the linear amplifier.
NOTE: The specifications for the SEND relay are 16 V DC 2 A. If
this level is exceeded, a large external relay must be used.
