Hi, A while ago (months) I did the extended temperature compensation procedure using the XG50, which seemed successful. I decided to tune up to 20MHz recently, and noticed when in CW mode, if I ran spot (manual) I was off, by a small margin (33Hz). I'm assuming this is normal as time goes on, is this a correct assumption?
Second question: assuming it is normal, and I should periodically re-calibrate using the XG50 or a known signal like WWV, is it safe to go to ref cal in the menu, unlock it, and manually tune/zero beat to adjust the frequency - without losing the calibration gained from doing the extended temperature compensation procedure? I'd rather not have to repeat that process any more than necessary, so I'm hoping the look-up table that generates is for something like offset based on temperature and so remains constant, and only the main reference calibration needs changing? I did this to test, and the menu item is still 'REF*CAL'. Tapping CMP while in this menu option, I have verified it is set to 'CUSTOM'. I appreciate any feedback, David ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
