Thanks Gerhard,
much appreciated
The questions I had was mostly regarding the MPDX-10 support, it is written on the feature sheet for the "Big" receivers that it is supported, but at JetPower Alvin was like one big question mark when I asked about it (I had previously emailed Germany about it, also no answer). It is not mentioned in any of the manuals, so I will have to find out myself, in a not too far future I will get the 12-22 connected, and be playing around with it
