HDHomerun HDHR3-US (non-cable card) hardware issue?
I purchased an HDHR3-US a few months ago to compliment an original HDHR model that I've been using for years. I was amazed at how much better the signal was on the new HDHR tuners compared to the old HDHR tuner - using timed recording, all 4 tuners on the same channel simultaneously, and then running the HDHR config app to monitor the signal strengths. Although they are both running the same firmware version, I wonder if the new HDHR's have been 'adjusted' to show a 100% signal when the older models may have showed only 85%.
I didn't put this together at first, but a few weeks ago I added a power strip to my cabinet, beside the new HDHR. I then started to get some strange artifacts in my TV shows. After verifying poor signal, I spent an hour or two playing around with the cabling and such, and right at the last moment, with the meter up on the screen, I moved the HDHR 8" from it's original spot, straightening the 1.5 foot quad shielded coax cable - the meter instantly went to 100% and recordings have been perfect since. Can anyone shed some light on what's going on here?

I'm guessing electrical interference from your power strip since you moved your HDHomerun (which also means you moved your coax) away from the strip and the signal improved.

I had already removed the power strip when I noticed the signal change so drastically. I'm even wondering about the cable simply stressing the HDHR unit a little bit and causing that ... I don't know, but it's downright strange.

Not many folks use these QAM tuners any more it seems, but as a followup to the original issue, I found a post over at the SiliconDust forums that suggested issues with regard to proximity of the HDHR tuners to wireless routers.
I pulled both HDHR's (new and old) out of my cabinet and separated them from the wireless router and sure enough, solid, strong signals once again.

The Hd Homeruns non cable card can also be used for OTA not just QAM the CC tuners cannot be used for OTA.
