Thanks for the info,my dish is a dish 500. I have one lead going to one dn receiver and the other to a 2nd dn receiver.I tried using an A/B switch using one lead to the in port of the a/b switch,and then on the out ports one to the stb and one to the dn receiver,but the cw700s is so sensitive it won't work that way.Even though there is 0 ohms resistance going through the switch.
I guess I'll keep doing it the way I have been (don't want to smoke the stb)
better safe than sorry.Thanks again San.
