[Elecraft] Scary K2 event this morning!!

[Don Wilhelm]

Eddy,

If you turned it on when its temperature was below 0 degF, that can happen.
The programmer's "bug-a-boo" of a maximum number of 255 and a minimum of 
000 has bitten you.
When the numbers decrease to below 000, the next "lower" number is 255 - 
which indicates a really hot K2!  Even if it is not true.
It is not really a big problem and can be solved easily in the menu.
Let it acclimate to the ambient temperature (an hour or so powered off) 
- and measure that temperature in degC.
Then enter the K2 menu for TPA and edit the parameter.
Set the parameter to match the temperature in degC and exit the menu
Job done.

In the future, let the K2 warm up above freezing before powering it on 
and that will not happen.

73,
Don W3FPR
