The problem with relying on RF detection is that the station is configured after TX starts rather than before TX starts. Perhaps for some owners this is not an issue. For me it is a significant issue. If the band change requires a change of antenna then my LP-100A may alarm on SWR before the KAT500 switches to the correct antenna and all the tuner relays clunk over to the proper selections. I much prefer to have my equipment configured before I transmit.
My first approach was to drive the KAT500 band discretes with band band data derived from the KPA500 BN; response. This worked well. I then took on the challenge of deriving the exact TX frequency (to nearest 1 Hz) from FA, FB, and IF. When this information is fed to the KAT500 then the band discretes are no longer needed. Now the KAT500 not only selects the proper antenna before TX but it should also select the proper memorized tuning solution for that exact frequency. I have some more works to do and that includes optimizing the integration of my KPA500 and LP100 data logging with control of KPA500, KAT500 and SteppIR SDA-100. I wanted to know what I had missed in K3 integration advantages so I can decide how best to implement the final solution. I had no Arduino experience before I started this project. It has turned out to be fun and rewarding (and sometimes quite frustrating). 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 arch...@mail-archive.com
