Set up a transponder as the KT 76-C. Set the VFR button (on a mux board) and it works but if I press it once I get a random code (different from what was currently set) and then if I press it again I get 1200. Sometimes if I press it shows a random code briefly and then goes to 1200 with one press. Once it is at 1200 if I press it again I get the same random code that showed after the first press.
My line for this button in the cfg file is as follows:
B39.15 XPDR_IDT v=1200
I added the v=1200 and have tried it with and without that parameter with the same results.
Just a minor inconvenience and wondering if I have not done something right?
One other thing I noticed during the setup - I choose the XPDR_CODE from the image map under Generic Display and it wouldn't display any code (display blank in that spot) when I choose XPDR_Code from the data table under Transponder Display it displayed correctly.
