We live in a motor home and change our service address and local channel feed when we change our job sites -- about 4 times per year. We presently are in the process of moving from Phoenix to Reno. We are currently in route and are on the very fringe of the Phoenix spot beam. We can no longer receive the HD spot beam and the SD spot beam from the 101 is variable. We receive signal at night with signal strength in the range of 50 to 75, but don't receive any signal during the daytime even if there are are no clouds or winds. Why would the signal be stronger at night than during the daytime? In anticipation of arriving at our address in Reno, we called in and changed our service address to the one we will be at in Reno. In our current location we had signal strengths of 78 on the 99s and 79 on the 119 for Reno local channels during the daytime, adequate for the new locals. But the feed did not change. We called in again, and they had us reset the boxes and they still didn't change from Phoenix to Reno. We then were transferred to a tech and he couldn't get the change to occur. He was about to bounce us to another tech when our phone wound up dropping the call. Before we call in again, can anyone weigh in on why the local channel feed would not change? We never had this happen in our 10 changes to our service address over the past 3 years. The local channel before always changed almost immediately even when we were changing them in advance of arriving at our new physical address. The first person I talked to was having trouble understanding the word 4th Street so I spelled it Fourth Street. Could that have triggered a conflict with there database of approved Post Office addresses? Just what does their system validate/do to make a change to the local channel feed?
