Re: FW: K3 and StepIR/Icom PW-1

[Greg - N4CC]

I'm using the K3 with a PW-1 and the beauty of it is you don't need
the ALC if you use the K3's capacity to store the power level (drive
level) for each band.  Obviously if you use the K3 barefoot at 100
watts you would have to be careful to turn it back down with the amp
but I just leave it at the saved settings that I have established for
output for each band.  The proper drive level does vary somewhat by
band.  You are right about the ALC ..the K3 ALC is not compatible
with the PW-1 and you should not connect the ALC line between the
two.  73 de Greg
