I'm pretty sure on mobile home systems, you will need the low speed jack to move the dish.......and i'm pretty sure the USB port on the D11 isn't even activated yet. Here's another problem that has came about with the D11 receiver. I am in a 72.5 market so therefore we use 4x4 switches in most standard installs.....the D11 WILL NOT auto configure on a Zinwell 4x4 if you are using less than 3 IRDs. We've reported it to directv and they are working on a solution. Kinda strange, but i guess the D11 isn't putting out enough amps to cycle the switch correctly. I've noticed the switches don't get as hot as they did with the D10's. Just FYI. I've also got the new DTV training video on the KaKu dishes coming in february, pretty awesome dish. Although it weighs 36 lbs lol
