I recently had my K3 (S/N 740) updated at the factory with the 2nd receiver and other relevant mods. It has firmware 2.78 installed and the rig was received back from Aptos about two weeks ago. Since receiving it, I have noticed that the Audio gain needs to be cranked up more than before. The rig never had gobs of rx audio, but I am finding it at 2 or 3 o'clock most of the time. I was on 30m with the bandwidth set to about 1.0 kHz and using NR. As a test, I shut down the AGC and it seems to have plenty of rx audio then (but of course NO protection...). Turn on NR substantially drops rx audio including signals... Even without NR, it seems a bit weak. I am not a young buck and hearing is somewhat addled, but no hearing aids yet!
Has anyone noticed changes in rx audio with either installation of the 2nd rx or somewhat updated firmware? If I upgrade to the latest and greatest (3.11??) what should the AGC settings be for general use? I know there were lengthy discussions here regarding AGC parameters, but didn't pay much attention when they came by. Is there a summary page/wiki somewhere?? -- 73 Allan K7GT ______________________________________________________________ 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
