Receiver problem maybe ?
My 211k and Tailgater goes straight into the auto mode when I power up, locates the sats, loads the program guide, and program comes on.
Are you going thru your RV wiring? If so, you might try connecting the Tailgater directly to the 211k receiver bypassing the internal wiring and see if it works that way. If so then you know you have a problem with the internal RV wiring.
And then try your receiver with your neighbor's Tailgater and see if that works.
