WARNING!
Set the transceiver output power and linear ampli-
fier ALC output level after referring to the linear
amplifier instruction manual.
The ALC input level must be in the range 0 V to
–4 V. The transceiver does not accept positive volt
-
age. Non-matched ALC and RF power settings
could overheat or damage the linear amplifier.
The maximum signal level of [RELAY] jack is
16 V/0.5 A DC with initial setting, and 250 V/200 mA
with “MOSFET” setting (see page 12-8 for details).
Use an external relay unit if your non-Icom linear
amplifier requires control voltage and/or current
greater than specified.
When using a linear amplifier that has a time delay
between receiving and transmitting, a high SWR
might cause the linear amplifier to malfunction. To
prevent this, slow the TX Delay the “TX Delay (HF),
(50M)” settings in the Others Set mode.
