[Elecraft] K3: Do you "Juice" your K3?

[Dave Hachadorian]

Earlier today, I remarked that one of my K3's was running 
warm in the NAQP RTTY after an extended number of RTTY CQ's. 
Tonight I did a little experiment - key down at 100 watts 
for four minutes while noting PA Temp and fan speed. It 
turns out that there really is no problem. Both K3's behaved 
identically and both leveled off at PA Temp = 64C after 
about 3 minutes. For the record, here are the results (best 
viewed with Courier font):

Time   Temp  Fan
0:00    26C   0
0:26    37    1
0:44    41    2
1:19    50    3
1:45    55    4
2:40    60    4
2:50    62    4
3:15    64    4
4:00    64    4

Room temp was 77F.
