    Hi All
    I have a HR54 with a LCC. The LCC works great on the channels I watch in the Dallas area. The only channel with problems, is channel 4 Fox. Lots of pixel breakups. I have checked the signal and its 100%. A splitter feeds the LCC and TV. replaced the splitter, no help, removed the splitter, no help, checked the TV OTA and there was no problem. So its the LCC and Fox, I replaced the LCC, no help. Anybody got any ideas ?

    You are lucky that the other channels work well. I tried the LCC and had breakup on all the channels. I also have an AM21 which also shows serious breakup issues. After extensive troubleshooting, I came to the conclusion that neither device handles multi path issues which I am likely facing, since I am very close to the TV transmission towers in my area. Like you, the OTA signal directly to my TV is pristine—it’s only the two DTV tuners that are unstable.

    Did you try to rotate the antenna? I have the same issue with one channel and just rotating the antenna about 10 degrees. Picture is now coming in.

    Bingo, rotating the antenna fixed it. Multipath is the culprit.

    Can we buy those LCC yet?

    Darn. Now I will have to try rotating the antenna. Is there and indicator in signal strength that will help me determine how far to rotate? Or just trial and error? Right now, I am pointed directly at the broadcast antenna farm and my signal strengths are all 100%.

    What part of the DFW area you live in, i live in Campbell in Hunt County, while i don't have a LCC, i do have a outside TV antenna hooked up to pick up the DFW stations. i have my antenna pointed towards the southwest since Cedar Hill is pretty much southwest of Hunt County. and also the reception is not as good indoors since Hunt County is in the fringe area of the DFW TV market where you need a outdoors antenna to pick it up. my advice is to adjust your antennas towards the direction of the Cedar Hill tower farm area. if you are closer to Cedar Hill, then you can have great reception inside or outside. but the farther you are, tye more likely you will be needing the outdoor antenna and to figure out what direction you need to aim towards Cedar Hil.

    It won't take much rotation and its trial and error.

    I'am in Casa View (far east Dallas). My TV signal cuts across the south side of Downtown so I get multipath from the downtown buildings.

    Hi All
    I rotated my antenna slightly again and channel 4 fox is now clean. Channel 8 is now on the verge of losing signal but no breakups. All else is fine.
    With the virus thing and people on tv using wifi hookups to get on tv its hard to tell if its them or you breaking up, so be careful.

    Well, I finally got around to trying an antenna rotation to see if I could improve the signal quality for my AM21. Here is the antenna:

    I tried approx. 10 degrees one way--no improvement. Then 10 degrees the other way--no improvement.

    This is my second AM21. The first one exhibited the same issues, so I asked DTV for a replacement. The newer device has a peculiarity. When viewing signal strength for the OTA channels, every channel shows exactly 85%. On the old AM21, I could see actual signal strengths, and they would vary from channel to channel. Not seeing a valid signal strength makes it more difficult when trying different antenna directions.

    I guess the next thing I could try is a new antenna. How likely is this to be an antenna issue?

    Directv hasn't had any AM21s for years, they will not replace yours.

    Where is this coming from? I said nothing about swapping out the AM21, which I already did several years ago. My question is whether I should consider swapping out the antenna, the only thing I have not tried yet.

    10 degrees isn't enough. I would try maybe 30 to 45 degrees each way, in small increments (maybe 5 degree). You could have a multi-path issue. Watch for a day or so after each adjustment - not just a quick check. Propagation changes over time.

    Unfortunately, I already took the ladder down. The only way to access the antenna is to hoist that ladder up unto my second floor deck, which is a PITA. I may give it a try since I have plenty of spare time during shelter-in-place.

    Can you comment on the fact that the signal strength indicators don’t seem to be working properly on this AM21? It would be interesting to hear if someone else who also has a newer AM21 is seeing the same 85% signal strength across all channels. On my older AM21 (which I recycled), I tried using a coax signal attenuator to resolve what seems like a signal overloading (or multipath) issue, but without valid signal strength indicators, this is now impossible.

    I have 7 AM21's on HR2x's and an HR54. I had to rerun the OTA setup on these because one of the stations had changed broadcast frequencies at the end of April. Afterward, I checked the signal strengths of the channels on all of the AM21's, and they all varied, from 25% to 100%. The two groups of channels and their subchannels that were below 50% are independent channels that are trace signals off a distant tower that the AM21 picked up that I have no interest in. Everything else that I did want to receive is between 75% to 100%. All of the AM21's were acquired during the HR21 / HR22 era.

    There are two variations of AM21, one that gives signal strengths up to 100, another where 85 is the max. Not sure why the difference, probably some slightly different hardware. It has been a while since I had AM21s, but if I remember correctly the ones that went to 100 had a low reading of 25, and the ones that went to 85 had a low reading of 7. So basically the same scale, just different end points.

    I have 3 AM21's and they all show 85% as max and 7% as low.
