Hi Ken,

You convinced me - CPU.

I would think that the likely suspect would be one that does
not already have a fan. I followed the signal as it went off
freq and faded. It climbed 3 kc on 40m then faded out.

Hi Ken,

I don't quite follow the implication of your statement. Do you have a
dual CPU system, where one CPU has a fan and the other not?

As it appears to be temperature based (the reason why the fan appears
to be significant) and CPU based (over clocked for its operating
temperature); I would suggest trying to cool the CPU with an aerosol
(freeze mist) or one of those cans of air for keyboard cleaning.

You can use the "canned air" as a freeze mist ("spray cold"), or
vice-versa, by inverting the can while you spray. They contain
essentially the same stuff, the difference being that the "spray cold"
contains a syphon tube to suck liquid up while the "canned air" doesn't.
