No. The menu setting is separate. If automatic control is enabled in the menu, and a very large signal is present that could exceed ADC range, then the K4 may *reduce* gain by backing off the preamp setting and/or adding small amounts of attenuation. After the problematic signal has disappeared, plus a few seconds, any automatic changes to gain will be reversed out, leaving you back at your original settings. In practice, automatic gain reduction rarely kicks in. I've never seen it happen outside of a Field Day scenario where antennas were in each other's near field. 73, Wayne N6KR ______________________________________________________________ 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]
