[Elecraft] K3 temperature

[Frank R. Oppedijk]

Hi Barry,

I have noticed the same. Here also, the FP temp settles at roughly 
36C, receive only. This is much warmer than before I fitted the KRX3. 
Ambient temperature here is about 20C. I have not investigated this 
phenomenon any further yet. I do consider it to be a bit warmer than 
normal operating temperatures...

73,
