I am able to peak on one of the birds, not sure which one, I think I am peaking on 119, not sure. Using one of those cheap tone boxes. I have been reading up here on this forum and I have to admit I have not run the switch test that has been spoken of in other threads. Basically I am getting a message that says the receiver has failed to connect. I hook the ViP222k back up to the antenna on the house and it connects right away to the birds. What I am trying to do is get the Pro 1000 to work with my ViP222K and then take the whole works RV'ing. The Receiver user's manual is a worthless, the antenna manual says the ports are 119, 110, 127, then LNA In from an external antenna, the labeling on the antenna say Port 1, 2, 3, & LNA In. I am wondering if this horn assembly needs an external switch...?
