FW: K3 and StepIR/Icom PW-1

[Adam Farson]

 Hi Tom,

The K3 should not be used as an exciter for the PW1 unless the polarity of
its external ALC input has been changed from positive-going (original) to
negative-going (range 0 to -4V). Failure to heed this warning will result in
extensive damage to the PW1, necessitating costly repairs (as much as
$1800!)

Cheers for now, 73,

To "Tom" , wherever you are--
I actually own a K3, PW-1 and SteppIR and have used them together. I was
involved in the beta testing of the negative ALC mod and if you have any
questions regarding my experiences please contact me off group.
