Good advice!! I'll redo the procedure after the radio has been in use for an hour. I don't usually have the LCD illuminated because of the lighting at my desk - does the display contribute that much heat?

I've have the external ref module which actually measures the TCXO frequency and on my K3 the drift is pretty close to over after 60 minutes. I've tracked it all the way to four hours. It is useful to keep an eye on the front panel temp (DISP - FP). The TXCO is located in close order with the front panel and that influences the drift. Mine usually tops out at 37 to 39C.
