Andy - I had a response from Dick D, and he suggested disabling Recall Tune on QSY in both MAN and AUTO modes. I did so, and the problem stopped ... for a day or two ... but comes back if I operate in MAN mode very long (I normally leave it in AUTO). I am using Counter for frequency info (ICOM). I believe MTM0 and MTA0 would do the same.
I have experimented with various FCCS settings in the past - including 50000 - and will revisit that. Basically, the KAT does not exhibit the stability it had when new (2 years ago). And I seem to need to go thru this whole process about every 6 months or so. My first step is always to check the antenna system, but that has not revealed any issues. Perhaps aging components are at fault. If there was a test for same, that would be helpful. But the issues are not critical enough for me to send it in for service since it is out of warranty, and who needs to clog up the Mother Ship at this time? 73 Lyn, W0LEN -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Andy Durbin Sent: Friday, July 09, 2021 6:19 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KAT500 80 meter anomaly "Is there a Command that would help to alleviate this behavior? Or a way to tell the KAT500 to ignore one or more of its preset frequencies that are causing issues?" How are you telling your KAT500 what frequency to use. CAT, Counter, or both? Is you KAT500 in MAN or AUTO mode? If you are commanding frequency with CAT then FCCS 50000; will make the KAT500 ignore counter frequency for up to 50 seconds and stop any toggling between CAT and counter frequencies. Commands MTM0; and MTA0; ought to help but, according to my test notes, they don't work as documented. 73, Andy, k3wyc ______________________________________________________________ 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 Message delivered to l...@lnainc.com ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
