Install has been complete for a few hours. A few notes
The installer did a great job outside, but was fairly messy inside. He left the boxes around the house for each receiver. The extra HDMI cables will come in handy, but I would have though he'd clean these up.
The TV2 analog sd tv's remote would not control the receiver unless I put my hand over the remote. The tech finally moved the remote, and all was well.
My signal strength seems a little low - mostly in the 60's and 70's. I have always heard that it needs to be higher to endure rain fade. Hope this isn't an issue.
The wired broadband wasn't working on the 722k, so the tech gave me a wireless usb dongle. Works great.
Dish Account Services is sending me a OTA module for the 722k, at no charge. I convinced them that being in tornado alley, it was necessary to have access to OTA during storms. They agreed.
The Dish Remote Android app isn't working. It says my receivers aren't online. Dish's web site shows one of them online, but not the other. I figured I'll give it a day for everything to be updated.
The install took about 4 hours, which is far more than I anticipated, but all in all, I'm happy. So far.
