Hi Lee,
I am fairly sure its not a software issue that you have introduced, as until today, I still had the other two units I built, and they are working fine. I swapped several components to try to isolate the fault, and by a process of elimination, I am sure it is in the ARF/IDC/POD assembly. After re-soldering, it worked fine on a couple of boots, and before I assembled the box, so it has to be either a bad solder joint or a dicky ARF/POD. I am pretty busy over the next week, so I may wait until Jeremy has the plug&play unit available before completing this PilotAware.
Best Regards
