I was trying to find out if the Auxbus works between the KX3 and KPA500. That would be ACC2 IO = TRN CTRL and connect ACC2 tip to the KPA500 Auxbus. The ACC2 Ring is already connected to the KPA500 PTT in and works fine.
There is no PC in the picture. My home station is completely PC controlled, but I am looking to simplify things for the mobile and have things as integrated as possible so there is no manual work to do. I also want to tune the screwdriver antenna using the KX3 as the SWR sensor. So, I think only a custom solution will give me all that. Just to make it a little more complicated, I use an Android tablet for vehicle monitoring with an ODB2 Dongle. I may also use that touchscreen to control the Ham Radio stuff, probably via a wifi or bluetooth interface to the ham radio controller, an Arduino or similar. I do have an extra ESP32 lying around. 73, Mark W7MLG On Mon, Jul 30, 2018 at 11:05 AM, Brian Waterworth < brian.waterwo...@gmail.com> wrote: > It does. I have used this setup for two field days.
