fyi .. after calibration room temp = 80F RX (dual) current drain 1.4-1.5A PA temp = 91.4F (no tx for last 2 hrs) FP temp = 100F (rx with dual rx for last 4 hrs)

bingo op error :-/ (why am I not surprised?) room temp was 27.7 *C* not *F* although it had actually been 20F outside earlier that morning Also, thanks for the calibration tip for the PA & FP temps I found they were both many degrees higher than actual room temp sm On 11/14/2013 10:56 AM, Paul Kirley wrote:

In a warm room there *may* be nothing wrong with an FP temperature of 41C after much idling. With a receive current drain of 1.5A, the K3 is dissipating 20W continuously. Of course, the PA fans don't directly cool the front panel. Have the Front Panel Temperature Sensor and PA Temperature Sensor calibrations been performed as detailed in the K3 Owner's Manual? 73, Paul W8TM
