A week or so ago I posted a problem I was experiencing with my K3; in SSB mode, I couldn't "crank down" on Mic gain to get the last ALC bar to flicker. I had either seven bars (Mic setting 3 or above) or none! The bars were solid...no flicker anywhere. On-the-air checks detected nothing wrong with my audio or signal...but I had 7 solid ALC bars! I was using a CM-500, plugged into the rear panel (rP.H bIAS selected). Elecraft support suggested that to set Mic gain properly that I first set CMP to zero, reset TX Eq settings, then set the Mic gain. I tried that and still had the failure.
I tried several other things: latest firmware upgrade, re-installing a known "good" configuration file, trying another mike (older lightweight Heil with DX element), reseated the KIO3 boards several times to assure a good contact, and even a borrowed mike that I plugged into the front panel (FP.H bIAS selected) -- all produced the same results, seven solid ALC bars or none! Support re-iterated that I try re-loading a known good configuration file. I did that again and it still failed. Then I thought back to his suggestion about setting the Mic gain properly; this time, instead of resetting the settings manually as I'd done before, I hit the CLR button instead, and the settings were reset. THAT WORKED! I was now able to adjust the setting so I would get the last bar to flicker. I could also see, if I was careful enough, the ALC reading increase from zero to seven bars, something it wouldn't do before. I've increased CMP back to the way I liked it but haven't played with the TX Eq yet...gun shy! I thought I'd pass this along, right or wrong, just in case it helps somebody in the future. 73, Bert N4CW ______________________________________________________________ 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]
