In general K3 owners bought for the high performance "numbers" The ARRL numbers on the dynamic range for 1.8 filter in the QST review provide "great results" but that is subjective - subjective. Far below expected numbers even if it is better then Brand x
The hamfest story below is great salesman hand waving - no numbers, no reposted test results To claim the problem is fixed implies that there are test results or to state another way, to claim the problem is fixed without posting test results is questionable I doubt the story below was in response to the ARRL article It's doubtful anyone will perform a retest - (ARRL certainly NOT) a Retest by someone outside the firm like Sherwood, etc. would be good ( although we maybe too busy reading about firmware updates.....hi) The ARRL QST article as minimum indicates that not all xtal filters of same model are equal back to RF, Robert w5aj ----- Original Message ----- From: "Fred Atchley" <[email protected]> To: <[email protected]> Sent: Friday, October 16, 2009 12:14 AM Subject: Re: [Elecraft] Flaw in the 1.8 kHz roofing filter At the recent Santa Barbara Hamfest, Eric addressed a problem with the early filters in the K3. The frequency would change unexpectedly. Eventually the problem was solved by cleaning. It was found that particles left over from the crystal manufacturing were modifying the freq. Inrad is just down the street from Elecraft and together they resolved the issue. I use the 1.8 in my K3 (#2241) with great results. 73, Fred AE6IC ______________________________________________________________ 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 ______________________________________________________________ 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
