I mapped out the connection on my 325, there are two output tv feeds and a 1 radio feed. The bedroom , living room and outdoor jacks were on 1 feed - splitter somewhere, figured behind the entertainment center but never put eyes on it. the garage tv was on its own feed. There is jpg on this thread from last year - I forgot 1 lead , believe it was the radio antenna wire.

My final test was bringing in known good cable to the bedroom, pulling the lead into the booster and see crappy signals through the booster to tvs. I replaced all of the coax ends but nothing helped till the booster was replaced. Bad thing is with the number of connections (radio and TV) you really cant replace it with an off the shelf Winegar unit.
