    Have you considered a service call with D* for a new LNB or dish?

    I did consider that, however, I don't know that there is a way to guarantee a WNC dish/LNB through D*, or is there?

    Solid Signal does not sell Slimline LNBs separately, I've already asked. They do sell the WNC complete dish.

    Here are 2 eBay listings for the WNC LNB: 140170829209 140171295975

    There are more listings on eBay, check it out. It's best to ask the seller if it's really a WNC since some might be incorrectly stated or not stated at all.

    I got one of the WNC LNBs and installed it right from the start on CalAmp dish. I have not compared readings by swapping LNBs but I might do that once I get my dish fine tuned (or more accurately, figure out how :) ).

    Go back to my "games to play" posting. The tuners swap [remember] so if you pull on SAT feed and your live TV drops, then the record tuner will be the "other".
    If the "live" TV doesn't drop, then change the channel "once" and you will lose your "live" TV.
    Sorry, sometimes I may not be clear. but I do need you to "follow" what I'm trying to say here. Then we can go through a logical process to figure out what is and isn't the problem. It will take some time and it does need to be systematical.


    All signals go through the BBC(s) some get up converted and some don't, but a bad BBC can cause dropouts in any frequency since the signal goes through it.

    Although it's unlikely any of these items are causing RFI problems in your case, we do have hard evidence that some people have found that dimmers and computers were the cause of pixelation problems with their HR20's. At this point, we don't know if its getting into the tuners via the AC cord, the outside of the coax onto the case, or otherwise. Consequently, you can not exclude an analysis of all possible devices in resolving your issue. As far as possible cures, in the perhaps unlikely event that you find one of these devices is the cause of your problem, we'll jump off that bridge we come to it.

    I wouldn't have any reservation buying a WNC LNB on eBay from someone with good feedback numbers: Lots of recent sales with very low negative feedback.

    For those who may be interested in this HR20 RF interference problem more generally, I just powered mine down and ran a few tests. As you know, unlike the H20, the HR20-700 does not have a safety ground through the AC line cord, so the case is not grounded. (I only have a -700 to check, so I don't know how the -100 is built.) Neither is the case connected to the AC neutral side of the polarized line cord. So it is "floating." I checked an H20-600, and the case is definitely grounded to the ground wire in the AC line cord. I'm not sure what their thinking was on the HR20-700, but this can lead to problems.

    That makes sense. As per K4SMX's suggestion I have ordered new BBCs from the D* website. It said 10-14 days for delivery.

    Stew,

    I actually like the "floating" electronic platform design and we (about 4 or 5 guys I have seen post here) could fill up another thread discussing the pros and cons. It does increase the occurrrence of RFI.

    They've been coming a lot faster than that. There was, however, a recent poster who said his online order never shipped. This may show up on your "Recent Activity" on the D* website as a "free" item when it ships, so if they don't show up in the mail in a week max or show up on the website, I'd give them a call.

    1) this "stuff" isn't easy so "dense as hell" doesn't really fit. [and why laying out a troubleshooting guide isn't cheap].
    2) There is no way to know after a recording is done what tuner was used [well ok I might but...]
    3) the games to play is live testing. You would need to pull a cable to know which tuner is live and THEN make a recording and see if it shows the problem.
    Then repeat the process with the other tuner [again by repeating the pulled cable to see which one is which]
    Until you: find it comes from one tuner or find that it comes from both.

    hiker: Aren't you the fellow who reported your computer was causing interference with your HR20?

    I just called them and had six sent out within days. "Screw the on-line" crap. :lol:
    [my first six BBCs (the old ones that came with the boxes) all failed]

    Yep, that's me. The only interference I've noticed is at startup on SAT 2 input. Since I currently have only SAT 1 connected, the HR20 gets interference from PC and continues to try to use SAT2 tuner. My workaround is to shut down PC if I have to reset HR20.

    Just a headsup...
    I ordered BBC's online a couple of weeks ago and never received a confirmation email nor the BBC's. I would think I should see an order in my account "View Orders" but I don't see one. I ordered again yesterday online and still don't see an email. Maybe the online order form is not working anymore. I'm going to give them a call.

    I just realized I'd better order some Rev. 3's for when I return to Florida. By what means are they shipping these? USPS, UPS, etc.?

    Thanks. I placed an order online yesterday, with no email confirmation or activity showing in my account online. I tried again this morning with the same results.

    So, I just called and ordered 4 new BBCs. The CSR said they'd arrive in two business days, didn't mention the shipping method though.

    If all the orders actually go through, I guess I'll have 12 BBCs!

    The bad hard drive sector is an interesting theory.

    I have all ten of the Planet Earth shows saved on the HR20. These were first run recordings and are flawless.

    With other recordings, my available hard drive space fluctuates between 25%-40%. Occasionally going a bit lower.

    If there is a bad sector, I'd think the problem would occur when my available hard drive space was reduced to a certain percentage. Does this sound correct?

    If so, that would explain the sporadic nature of the problem. As I delete recordings, my hard drive capacity increases and the bad sector would not be used. Conversely, as I save more recordings, the hard drive capacity decreases. Thereby "exposing" the bad sector. Does that make any sense?

    The bad drive sector is pretty far down the list of potential problems and I would only look into that after exhausting the other options.

    Even live TV is written to harddrive so, it can present at any time. I don't think that this is your problem and only included it in the list to be comprehensive.
