[Elecraft] KXPA-100 to ICOM PW-1 amplifier

[Josh Fiden]

Sorry, my error. You CAN use ALC to control drive power, but it should 
not be used for that purpose. If you set the transceiver to 100W and let 
ALC reduce it during normal operation, you generate trash in your 
transmitted signal.

Prior to replacing my Icom transceiver with the K3, a neighbor 
complained that I had bad key clicks. Turning down drive power on the 
transceiver, rather than relying on ALC, substantially improved my 
signal. This was using a PW-1.

PW-1 uses ALC for protection. Unless I misunderstand, running the PW-1 
without ALC, even directly from a KX3, may not be a long term reliable 
solution.
