I too am having RF problems but wiht the Marantz 5200 remote. I was also thinking of opening up the base unit and seeign if it is possible to lengthen the antenna. I dont see why it would be so bad for Marantz or Phillips to add a short stubby antenna to the remote as an option. It would kind of look like a cell phone antenna at the front of the remote kind of like a Nokia! Or do this for the base station. has anybody openend up an RF base yet?
