Here's a follow up to all of your questions above.

(Capt John) I had tried both of my JR transmitters XP8103 and XP9303 with no response to the connectors. That's in conjunction with using the OMP JR micro adapter (Don Preston) which I also purchase thinking it would solve my problems; which it didn't. (Crowfly) please let me know if yours works as soon as it comes in; mine is still "in the mail".

I hope this helps you guys. This has been extremely frustrating for me!!! Jim
