Bill - Over 5 years elapsed between v1.75 and v2.05. In that time, many changes were made including several that relate to frequency adjustment and precedence of transceiver data (which Icom does not supply) over counter data.
It would seem logical to "teach" the KAT500 your frequency settings once again with the new firmware. I did that, and the newer version performs better - for me (with Icom) - than v1.75 did. There is an Elecraft document detailing changes, "KAT500 Firmware Release Notes" that may be helpful. 73 Lyn, WØLEN -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bill Mader Sent: Tuesday, August 23, 2022 3:33 PM To: Elecraft E-mail Reflector Subject: Re: [Elecraft] Problem with KAT500 firmware v. 2.05 While this may be an old thread, I have an input which could be interesting to some. I recently noticed the KAT500 I am currently using had V1.75 of the firmware installed. I use it with an IC-7610 and trained it on each HF band, placed the MODE switch in MAN and tuned it for the FT8 frequencies. This worked well until I updated the firmware to V2.05. After that, the KAT500 failed to use the memorized tuning solutions even though its frequency counter correctly identified the frequency. It would operate in AUTO mode but the tuning took too long for my purposes. I reverted the firmware to V1.75 and it performed as it should. The question is why does V2.05 appear to ignore what should be memorized tuning solutions? 73, Bill Mader, K8TE ARRL New Mexico Section Manager *ARRL - The national association for Amateur Radio**™* Secretary/Treasurer and Past President, Albuquerque DX Association W6H NM Coordinator, Route 66 On-the-Air 10-18 Sep 2022 New Mexico QSO Party 8 Apr 2023 Duke City Hamfest Chairman www.dukecityhamfest.org 15-17 Sep 2023 ______________________________________________________________ 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
