[Elecraft] Cold K3

[Bill Frantz]

During the California QSO Party, the temperatures in our 
operation tent dropped below freezing. Two of us felt that we 
were not getting full power out of our K3s when the internal 
temperatures were low. Given that we were using the K3 to 
measure power output, low temperatures could be affecting the 
measurement rather than the power.

After sending CQ for 5 or 10 minutes, the K3s warmed up and the 
output power rose to normal. Too bad calling CQ didn't warm the 
operators as well. HIHI

Since we were getting about 90% power with the internal 
temperatures at zero C, it is not a major issue, but we are 
curious. Has anyone else experienced this effect?
