I thought I made it clear that the radio, per se was not the problem, , it was a user, me, error.

However, it is possible on the 28x , as I found out, that the presentation of the X bus servo/ converter harness page needs extra care from the operator, particularly in strong light conditions ! It is a potential “gotcha” rather like the engine presentation on the original B 737-400 which led a crew to shut down the wrong engine after an engine failure, with dreadful results.

I do agree the 28x is a very fine radio indeed, just off to go flying with it !

I won’t make that mistake again and I made these posts in the hope it will reduce the chances of 28x users making my mistake and being extra careful to use the correct SET button.

Many years ago, at an early IJMC meeting I suggested we create an incident reporting scheme, similar to those which are used in full-size ops. I would collate and publish a quarterly review of such incidents, in the interest of promoting flight safety. It was not taken up.
