Re: KPA500 fan noise

Please post your experiences, Don.
During the SS CW, I was (for the first time) conscious of the fan noise
when it went into 'high gear' during extended CQs. It did make the weak
sigs more difficult to copy (even through my headset).
I've had a few looks myself, but haven't yet taken the cover off.

One thing I tried during a recent contest was to set FAN CTL = 1 during
the contest, or at least whenever I was CQing. The noise level stayed
constant instead of jumping up and down with the PA temperature, and a
constant noise level is easier to cope with. Outside of contests, I set
FAN CTL = NOR, because the fan rarely if ever comes on then.
