{Collins} Re: need info: KWS-1 VFO drift



Bob,
Let me introduce myself. I am the one that wrote "The Care and Feeding of
Your KWS-1", a CCA quarterly back when it was a magazine and it was
dedicated to the KWS-1. What you are seeing is common and typical. The best
solution is a simple non-destructive fan modification (small muffin fan
added internally by the PA cage that SUCKS air from the front (cool) end of
the exciter, over the PTO area, and exhausts the air out thru the back
louvers. This will eliminate the drift you get when going from xmit to
receive, particularly on long overs.
You will have to get a fan that runs on 115V and is small enough to fit in
that space and power it externally. It really helps.
Let me know if you need more than this.
