I'm looking at subscribing to Directv. Need a couple receivers for house, and one for my camper. However, a friend recently had a system installed and stated that directv uses a new thing called a "swim" device ? Keeps you from running dual cables for DVRs, etc and it all works with one cable. (I hope I'm saying this right as I'm not up to speed on these things). He stated that if you don't have your receiver plugged into this that every 30 days the receivers talk to each other and if it doesn't see the receiver, it will cancel the receiver. So my question is whether this happens ? I don't use the camper often, and sometimes months before using, but it would be nice to use satelite when we do go. But, this spare receiver won't be used very often. Will this new system actually cancel my service if it's not always hookep up ? Thanks for any advice. I don't want to get the extra receiver if that is the case.
