Sam K5OAI sed: > room temp 27.7 F
Unless the room is in an igloo, he probably meant 27.7C = 82F. Good temperature benchmarks to keep in mind are: (a) 20C = 68F is "normal" room temperature; and (b) 37C = 98.6F is "normal" body temperature. Naturally, the K3 temperatures will be higher than the ambient temperature, as the K3 dissipates part of the energy coming into it from the PS. The K3's PA fans are designed to run unless the PA temperature is 36C or less, so the PA temperature will tend toward 36C unless the room is cool. In a warm room, 36C is a pretty normal PA temperature reading. 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 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
