It's probably just as well that you didn't do the RF Gain Calibration. The most recent versions of the Utility (e.g. 1.3.9.xx) were not properly saving calibration parameters. I went through many pushups discovering this with #4717...not far past your #46XX. If you do get an XG2, be sure to download the latest K3 Utility (at least 1.3.10.11 or later) which correctly saves the parameters. If anyone else has done RF Cal recently (i.e. in September), you should redo it with the new Utility when released. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-AGC-THR-doesn-t-go-low-enough-tp5614723p5629218.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ 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
