Hangglider,
Your Feller BeamIT remote arrived this morning.
I did a quick 10 minute review of it and I can see why Lintronic and everyone else has been having problems and also why the B&O supplied XML will never work and I guess it was not tested unless it is intended for a different Feller remote.
This remote appears to use an "Unmodulated" signal, in other words there is no carrier frequency which is a big problem for most receivers because the normal way of determining the "pulse" size is to count the carrier frequency periods which in this case cannot be done.
Tomorrow I will do further tests to see if I can come up with a solution to this issue.
