Hi... I am hoping that someone can help. Yesterday we got hooked up with DTV. I previosly had dish network. I told the tech that I had a couple of old DTV dishes at our cabin and I was wondering if I could tak one of the single recievers up there when we are on vacation. He said they would work with the 18" round dishes. The recievers are H24-100. I have been trying to hook one of them up and cannot find the signal. I have the direction and angle set as close as I can with a compass and using the gauge of the pipe. The pipe is plumb. I have the reciever set on 18" dish and using a multiswich type. I turn on the receiver...it eventually goes to code 771 "searching for signal". I go into menu and setup to set it to the correct dish type and switch type and then hit continue. It verifies connection and then tells me that it could not detect a signal and I should verify the set up. I appreciate any help I can get with this... Hartwa.
