One pair?? Assuming you did this mod adding a remote power supply. WOW! So it would work on any twisted pair like 22-2 or 18-2? Does it have to be twisted? No Sheilding either? Let's say I had an extra RG-6 running to the base station? I'm only asking to prove a point. I know that everyone would like to believe Cat5e is the future proof wire. It can be, but as for a power supply issue, you must make the RF base station able to be powered remotely. Good find! Great job. I would make URC take the original base station off the shelf. And start adding this to fix the buggy RF issues. I mean, what if you had installed an MSC-400 and still had issues trasnmitting?

I'd be pissed too!
