Been on holidays for 3 months. Had my units fall over and tidying up my settings now. (Unfortunately lost all my precious recorded data with FA because new setups recorded when reconnected ) Currently working both mutability and FA versions of 1.15 / 3.50. I have been trolling through trying to find the latest set up for range circles, which I have had working in previous versions. Indeed on SD card updated to current versions and still has working range circles etc. But having trouble setting up a new SD card with the correct settings. Just a link to the setting that will work with the latest 1.15 / 3.50 versions.
