Losing Audio DISH 811 and OTA

Hi, This may seem simple to you all, but it is a PITA to me. I have a DISH 811 (2 actually), they are set up with an OTA so I can get local HD. Most of the time it is great, but too ofter I lose audio on my Fox channel. The channel is about 68 miles away. The video stays great, but I lose audio. If I turn off the receiver and back on, the audio comes back for a while, then goes out. The signall strength is running about 68-80 most of the time. I had the receiver swapped out, same problem. I guess my real question is, would an RF amp help resolve the problem? Should I attempt the upgrade to the 211?

Thanks for your suggestions.

Not exactly the same problem, but my audio would cut out occasionally too on my 811. I doubt the amp would help...........

If you want the added Voom and espn2HD, and univHD, you'll need a 211 or a twin tuner 622HD-DVR. The added channels will only be in MPEG4

The problem is in the 811 receiver. This also happens to me on my local HD stations, mostly FOX, and NBC. A easier solution that I have found is to switch stations quickly and the audio returns
