[ICOM] Icom PW-1 Failures - How To

[Adam Farson]

Hi Mike,

Agreed. In general terms, the exciter's internal autotuner is not needed
when driving a solid-state amplifier. To my knowledge, all solid-state HF
and HF/6m amplifiers have a broadband input circuit which presents a flat
50-ohm resistive load to the exciter. 

If matching is required, the amplifier's internal ATU (if fitted) can be
left in the signal path when the PA stage is off-line. It will match the
load, and provide some additional preselection on receive.

Better read the manual.  It states NOT to use the rig's internal tuner when
using the PW-1!
