[Elecraft] PA Fan

Sun Dec 8 11:39:01 2002

My low-speed fan comes on around 38C.  According to an errata correction in 
the manual, the high-speed fan should come on at 40C.  Did you do the 
"retightening" process?  After 10-15 hours of run time, you should go back 
into the K2/100 and retighten the screws holding the PAs (and the sensor). 
I would be interested to know from the Elecraft gang whether another 
retightening at a later time is advisable.

best wishes,
