Thanks, Bill, for the very nice write up. I'd like to mention that on the K2 - and I imagine on a K3 that I hope to own one day soon! - you can cycle through all four combinations of ATT/PRE on/off if you use software. I wrote a bare bones (i.e., ugly!) C program that performs some k2 cmds. I originally wrote it to first do a low power tune and then a high power tune, but have added more functions as time went on. Eventually I added a 'level' cmd so that I can choose between RF gains of +14, +4, 0, and -10 dB using the various att/pre combos. Nothing major, but maybe lets you further fine tune your rf gain settings. 73, Mike ab3ap ______________________________________________________________ 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
