RE: MC22 switch adapter
Hi Norman.
I also use an MC-22 with Weatronic module, but I skipped all my 35MHz gear, so I have no experience with the switch module.
But, I have had good luck with calling Weatronic when I have had some questions. The guy I got on the phone last time spoke english just fine, although you have to live with the ´Allo ´Allo! style dialect... :-)
