[Elecraft] PA temperature checking: CAL tPA

Just to clean up any remaining mystery:

The latest revision of K2 firmware, 2.03, provides only one way to check the
KPA100 heatsink temperature from the menu: the "CAL tPA" function. This is
normally used for calibration, but you can also use it to display the heatshink
temperature at any time.

In older revisions of K2 firmware there was a "PA tPA" function (in the
secondary menu). This allowed display of the PA temperature in TUNE mode. This
feature was really intended only for our own use during KPA100 development, but
we left it in for field test purposes. We then removed it since the CAL tPA
function provided an adequate way to check heatsink temperature. (The heatsink
cools down slowly enough that you can enter CAL tPA right after transmitting and
see what the reading is before it drops.) 

Upcoming revisions of the K2, KPA100, and K2 Rev 2 Firmware manuals will all
reflect this change. The recovered code space has been put to good use.

Sorry for the confusion.
