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. 73, Don W3FPR On 7/24/2012 10:10 AM, Stanton A.
