About a year ago, I remodeled the upper level of my shop to house a dedicated game/movie room that was separate from the house. I called DirecTv and had them install the lines running from the dish to the room.
I used it for a few months, then moved the TV to the house in anticipation of the purchase of all new components specifically for this room later in the year.
I now have a Sony SXRD, Onkyo 705, PS3, Xbox 360, and a HTPC.
These components as well as the HR20 are connected to a Tripplite Home Theater UPS. with everything hooked up through filtering only and just the DVR connected through the battery output.
I also have added an In-wall A/C unit and a mini-fridge and microwave for drinks and popcorn for movie nights.
The appliances are connected to a different outlet, but i know they share the same circuit.
At this moment both tuners signal strength meters are bouncing between 70% and 79%. Now I expect the signal to be lower than the Hughes Tivo and Hughes Tivo HD receivers in the house because they are both close to the Dish, while the HR20 has a cable run of about 70 feet, but I don't know if they should be this low as well as fluctuate so much. The tuners inside the house seem to never have signal problems.
The severe problems start when:
The compressor in the A/C is on
The compressor in the Fridge is on
The microwave is on
Or if anything else that takes a large amount of power (like a vacuum) is on.
All of these appliances are at least 10 feet away.
If any of these things turn on, the signal will go down by at least 20% which will cause either a loss of signal or severe pixelation, audio loss and will not recover until the appliance is switched back off.
My attempts at troubleshooting include:
had 6 trees cut down that the Directv guy said may be or will become a problem, hoping that would help the signal.
I then thought that maybe the UPS was causing issues, so I plugged the HR20 directly into the wall socket and it had no positive effect.
Then, just to see what it would do if I isolated the HR20's Power input from the wall completely I unplugged the UPS from the wall and ran the unit off of the UPS' battery backup power, and to my surprise, It lost ALL signal.
Supposedly my UPS has a filter, this has no positive effect, and I still don't understand why when the UPS is powering the HR20 solely on battery power it has NO signal. that aggravates me further, because I bought the UPS to power the DVR in the event of a power failure, so It could continue to record TV.
I have searched well, and have not heard of any similar issues, I'm truly stumped .
