I have an R-15(that I activated Saturday) and an R10 that I have had for about 3 years. I am using an old DISH 500 dual lnb dish on just one side. The LNB is at least 8 years old.My multiswitch is about 7 years old. We had a bad storm today. When I came home today the R-15 was only getting signal on 1 tuner. The R-10 appeared to be fine. Now the R-10(that did have both tuners working) comes and goes. It was lose the satellite signal on both tuners. Seems like it is affected when I hook the coax to turner 2 on the R-15. When I do the R-15(the one with only 1 tuners that works) looses signal on both tuners. Any ideas?
