Hi Wayne, Can future KPA1500 firmware allow the smaller bins to be utilized via standard CAT protocol over TCP/IP? I can feed the amp exact frequency info via a Node Red Raspberry Pi. Right now using CAT over the KXUSB cable. Also it would be desirable to have CAT take priority over internal frequency counter on the amp. I've had the internal counter fail and the amp was in never never land when trying to transmit.
I do have to say that after all the mods were done (current to when I sent in the RF deck) the amp has worked flawlessly. Many thousands of QSOs. Any way to track if there are additional mods to the amp that have been incorporated since last serviced? I would think if there were something major that existing owners would be notified. 73 Dave wo2x -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Wayne Burdick Sent: Monday, July 20, 2020 12:26 AM To: Andy Durbin <[email protected]> Cc: Elecraft Reflector <[email protected]> Subject: Re: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution Andy (K3WYC) wrote: > I still don't see the advantage of AUX bus giving the KPA1500 the TX frequency to 1 kHz resolution. What am I missing? Hi Andy, The improved resolution ensures that the correct bin is detected when you get within +/- 1 kHz of the target ATU LC data bin rather than +/- 8 kHz. This improves repeatability of selected LC values vs. VFO frequency, especially on 160 and 80 meters where it's most likely to matter. This also means that, in the future, we could use smaller bin width on some bands if desired. This could be helpful if you were using the ATU to fine-tune a very narrowband antenna such as a loop or electrically short vertical. 73, Wayne N6KR ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
