This works for a while, until finally one loud signal blows out the K3's audio amplifier. This is the second time that has happened to me. I guess I'm a slow learner on that issue.
Something really needs to be done here. My suggestions would to raise the agc threshold further, and increase the slope of the agc line (that would mean a slp setting of less than zero). The AF limiter threshold also needs to be raised, and the AF speaker output needs better protection." With all the discussion of AGC on/off, threshold levels and gain throttling, etc. for improved performance in pileups, I haven't seen any further mention of what I consider to be the most serious problem reported by K6LL, namely that the K3's audio amplifiers can apparently be damaged by user control settings. If this is considered acceptable (I don't believe it should be), are these control settings adequately described in the K3 user's manuals and updates? Is the susceptibilty to damage confined to K3's where the hardware audio modifications have yet to be made? 73, Chuck Guenther NI0C K2-10 s/n 5853 K3-100 s/n 1061 ______________________________________________________________ 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
