[ICOM] IC2KL Bias supply

[W. David Paperman]

Adam;

Thank you for the information. I have encountered the "Birdie" problems 
before on my IC2KL. Tightening screws helped most of all in reducing the
problem to a couple of frequencies on the 10 meter band.

With regard to the PA transistor substitutes I have not yet encountered 
failures in the finals in any of the 'KLs I have repaired. I feel 
certain that the day will come.

I have seen 2 solid state amplifiers in which I have confidence; the 
IC2KL and a brand "X" (this being an Icom list (:-)). I have not yet had 
the opportunity to work on a PW-1.

Incidentally, I obtained mine in a "horse trade" from a merchant marine 
captain who had purchased it in Japan. It is one of the earliest 
versions and, with 2 repairs to the bias supply, still performing in 
contests and DX chasing.

Dave, W5WP
