[Elecraft] K2 portable problems

[Don Wilhelm]

Stan,

Take a look at the CAL TPA menu setting.  When the KPA100 has been 
unused for a while, set that menu parameter to the ambient temperature 
in degC.
If you had power on the K2 when the temperature dropped below freezing, 
that would have caused CAL TPA to become messed up - it wraps around 
when the temperature goes below 0 degC - starts at 255 and decreases 
from there - so the K2 *thinks* the temperature is hot when in fact it 
is very cold.

If you want to operate in cold temperatures, I would suggest that you 
temporarily set the CAL TPA parameter to 10 degC above the ambient 
temperature - sure under normal conditions, the fan will come on much 
earlier than it would normally, but if you are operating in a cold 
environment, the fan will most likely stay off anyway.  Don't forget to 
reset it when you get the KPA100 back to the shack.

That may or may not cure the Hi REFL messages.  That is usually a result 
of a coax or antenna problem.
