I have a DPP 44 with a DP Plus on a 500 and a 300 aimed at 61.5. I am also running the 625 with 1 cable and splitter. The 625 has been loosing the signal and tech support said to check the cable so I hooked up another cable and it is still doing it. Locals are going out during the day and when I go to any upper channel it come in and then can go back and locals are there. My other receivers are a 510 and a 310 and they are not having this problem, Can I unplug power inverter from the DPP44 and use 2 cables for the 625 and run it that way. Also it was loosing the signal every morning when it was allowed to update, I have since disabled that and mornings are ok. Would rather not have a service call but my 625 is still under warranty. Also signal strength is about 20-30 point lower on 625 than the 510 or 310.
