TIP with dish:
I have no used my receiver since end of July. I went to turn it on last week and it had auto deactivate (even if your still paying for it). The deactivation is done automatically inside the hardware and I do not know if its a couple weeks or a month when it happens.
Since there is not an outbound connection from your receiver, there must be a steam of serial numbers that is always being transmitted by Dish to keep paying customers receivers running.
To get it re-activated takes a call to dish (I hear you can do it over internet?). Hopefully you will get someone in USA to talk to. So if your planning on going somewhere that has no internet/ cell phone, be sure to make a test run before leaving to see if the receiver is still activated with Dish :).
It can take 15-20 minutes after they "send the signal" before you receiver starts to work again. but most customer service reps are in a hurry so they will have you reboot the thing several times.
I have a winegard Pathway X2 dish. In the NE US we use different satellites than the rest of the USA (for HD content) and the X2 is the only portable dish that does this "eastern arc".
