Don, many thanks. That looks like the right explanation. I hadn't spotted it in the manual. 73
Geoff G3UCK -----Original Message----- From: Don Wilhelm Geoff, I believe the key to your question is found in the menu explanation for the TXGN menu entry. >From that description, I conclude that the "magic" is in having the power setting at 5, 50 or 1.0 mW. The gain constant is only updated when Tune function is activated and one of those 3 power levels is set. At other power levels, the gain constant is not updated. 73, Don W3FPR ______________________________________________________________ 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
