[Elecraft] Re:K2/100 Frequency Stability

[WA9GQT@aol.com]

Hi Ron & others! 
      I also have noticed an increase in drift with the KPA100 added.  Seems 
that typical drift for me after at least 1 CW or SSB contact is about 70 - 
100 Hz.  I have only been running it at  50 watts. The other stations have 
not commented on any drift, but if you check the 4 mHz or 10 mHz calibration, 
it has definitely drifted by that much.  
      I think there may be a way to get more air circulating thru the K2 by 
possibly using small holes in front plate of the KPA100.  I do not feel any 
air flow from heat sink area at all.  By the way my fan is set on low/hi, so 
anytime I turn my K2 past
10 watts the fan is on low.  Then it kicks to high when the heat sink gets 
hotenough.
I think this is the best setting for the fan.  Hopefully we will get more 
feedback on this matter.  Thanks.
