I apreciate all the great comments - thanks.

I was wondering whether someone might ask that. I've been asking myself the same question.

In one word - yes! I really ought to use a 6200 unless I wish to kiss this one a quick goodbye. I guess I'll have to pull one from another project I have on the back burner. Fortunately, it doesn't change anything for the radio layout - the Aux RX will just mount against a fuse side with foam tape.
