I have three receivers, HR24-500, HR24-100 and HR20-100. I live in a fringe area for the next state over's local channels. I had the bright idea to change my equipment location to our vacation home in that area so that I could get their local stations because I want to watch one of the sports teams there. Anyway, I thought it was a flop because the HR24 receivers say they are searching for the satellite. However, the HR20 receiver gets all local channels just fine. What is going on here? Thanks.
