[Elecraft] Operating temperature range ( second attempt)

[Igor Sokolov]

Thanks Jerry. +8F (-13 C) is the lowest mentioned here so far for KX3. I 
will have to wait till next winter to try temperatures lower then that. Now 
it only gets down to minus 8C in the night and day temperatures are all 
above freezing.

I’ve run my KX3 at +8F with no problems but that was SSB. I’ve not done any 
temp compensation on it. Also,
the radio was ‘warm’ +60F when started but was outside in the cold at +8F 
for about 5 hours.  It may have generated enough heat internally to help and 
I’m not sure if a cold soaked radio would operate the same from a cold 
start.  Great little radio!!
