I finally unboxed my PW-1, after it’s repair by ICOM,
and plugged in the K3. I connected the KEY-OUT to the SEND2 connection on
my PW-1, connected the K3 to INPUT2, set the power down to 25w, powered up the
ICOM PW-1, pushed in AMP/PROTECT so it was GREEN, the K3 is in CW VOX mode,
keyed the K3, and the PW-1 only reflected 25w output. The PW-1 TRANSMIT
light never lit up which says I’m not keying the PW-1. I have the K3
PW-1 negative ALC mod installed, but did not connect it up to the PW-1. I
ran the PW-1 with the K3 from last December, through June of this year,
configured this same way with no problems, 25w of drive will output around
1100w on 40m CW. I don’t need the ALC mod but it is a nice safety
net if I actually connect up the ALC connection on the PW-1. Last year, I
had the ICOM756ProIII connected to input 1and the ACC1 interface to the PW-1
was connected, which basically supplies power to the PW-1 antenna switch when
the amp is in the off position. The PW-1 Is in the INPUT1&2 position.
Does it make a difference that there is no transceiver connected to INPUT1 and
ACC1. That is the only real difference. I know that there are a few
(more than a few) K3 owners with PW-1 amps. I am probably doing something
wrong but it sure isn’t obvious to me. My firmware level is 2.38 on
the K3. I guess I could try plugging into the Input 1, send 1 inputs on
the PW-1 to see if that makes any difference. The PW-1 manual does not
indicate that a transceiver has to be connected to the input1 connections on
the PW-1.
