Earlier, "rumbles" were mentioned along with "artifacts" and all manner of audible squeaks and chirps generally hidden in the K3. I thought I had finally fully recovered from my IC-756 experience, and now this issue reminds me of that old unpleasantness.
Background: I like ICOMs and have owned or operated very many including the all 756 series through Pro II. My early Pro had low level "rumbles/artifacts", barely audible in quality headsets on a quiet band. I reported same to my Dealer, ICOM, and finally the ARRL during their initial testing. Read their review for a discussion of that discovery. It was really there but at a low level, and thanks to a couple of gifted HAMs, the source was discovered and remedies suggested. ICOM denied the issue in written and spoken coms to me and others (I sent mine in for an ICOM checkup, and no problems were noted). They later fixed it by offering us a new improved model that was rumble-free, the new Pro II. It was an expensive repair to say the least versus potentially what could have been a few changes in circuit components. Patience, and reconsider any suspicions surrounding Elecraft's continuing development policy. Their improved DSP board is a relatively free gift compared with buying a complete new radio as ICOM once offered the amateur community. Thanks to it's design, the K3 platform is simply a work in progress. I'm looking forward to additional upgrades by Elecraft as time goes by and the K3 evolves. That's one reason why I decided to support our American company with my $. Thanks for your time. 73, Gary NL7Y ______________________________________________________________ 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
