I had been monitoring the signal strength on 110, 119, and 129 on and off this morning. The signal on 110 & 119 was OK at around 45. But signal on 129 Tp12 was now under 30 and the HD locals and other channels that we get off 129 were heavily pixelated. The "complete signal loss" warning was up most of the time.
I quickly installed the Hooper 3, Hybrid LNB and Solo Hub as soon as they arrived this afternoon. The install went without a hitch. The only slow part was downloading the current software, etc.
Once the H3 was setup and activated, I checked the signal strength. ALL three sats were around 50! And the HD channels, including our locals, were clear & clean

This upgrade replaced all the "moving parts" of our install. The sat dish and coax stayed exactly the same. So it is hard to say whether the issue was the old LNB, ViP 622, Separator or some combo.
As it turned out the biggest delay to getting up and running was not calling Dish for activation, That process went extremely well due to a very helpful Dish rep. Once the H3 was activated the main slow down was learning how to use the new Remote 52! Old dog, new tricks… you know the story.
