[Elecraft] My K2/100 is up and running, first go :)

[James Cutler]

Just a quick note to say that I have built the KPA100 and installed and 
aligned it, and it is working fine on all bands. When I built my K2 at 
the beginning of the year, it also worked fine, and still is. I have to 
say that over all, I am happy with the radio, and it's performance.

I have one query though, I am wondering why Elecraft have opted to use 
thermal pads on the PA transistors in the KPA100 as opposed to heat 
paste? (A lot of linear amplifiers that I have seen over the years use 
thermal paste on the PA transistors without apparent problems.) I just 
suspect that the thermal resistance of a thermal transfer pad may be 
higher than that of thermal paste......please advise me if I am way off 
on this point.

Cheers and 73 to all......
