Ed, The PA temperature has not been properly calibrated.
Check the menu entry for CAL TPA. Turn the K2 off and let it acclimate to the ambient temperature, then set the value for CAL TPA to the room temperature in degC. If you do not have a thermometer that reads in degC, convert from Fahrenheit by subtracting 32, then multiply by 5 then divide by 9.

Once in a while, immediately after turning on K2 (SN 3500+ with all mods) I hit the CW key and get a: PA HOT message. Any thoughts what's going on here, rig is cold, so PA can't be warm. Cycling off 12v power seems to fix this?
