I suddenly came up with several problems related to audio volume on my K3, MCU 4.51.
I was listening on USB with slow AGC and I noticed that the volume would suddenly drop and remain low until I hit the T/R button, whereupon it would come back again, and then disappear. I switched to fast AGC and the problem diminished but did not disappear. So I reached for the audio volume control and discovered that it now turns 360 degrees without a stop, although there is a slight detent at the regular stopping point. I tried to turn AGC off, and although the display indicates that it is off, there appears to be no increase in volume. I now feel that the volume is lower than it was when I first built the unit. There may be some troubleshooting to do here. I notice this less with strong signals. I guess I would like to know what to do about the rotation first, and then pursue the overall volume problem. Thank you, Jan, KX2A ______________________________________________________________ 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
