    I had my service call today ($49 fee waived since I'm a loyal customer with no service calls in the last 12 months). First he replaced the existing 5LNB with a new 5LNB (non-SWiM). I asked about the non-SWiM 3LNB, but he said that wouldn't make any difference, which seemed to be the consensus here, so I didn't push him about it. Then he realigned it, and then he replaced the grounding block and put all new ends on all the cabling outside that connects to the grounding block (8 ends altogether). After all that, my signal strengths are not much better. The 99c TPs are now all in the low 90s, but both 103ca and 103cb are still in the 80s with 103ca TP 17 in the 70s. He then went back up and realigned it again to no avail.

    Both my HR21s are given me similar results, so I don't think the problem is with any of the tuners. I guess I'm just not destined to have all TPs in the 90s. :(

    I felt bad for the guy: it's about 90 here today and he had long heavy looking cargo pants and a heavy looking long sleeve dark blue D* shirt and a hat - I would have passed out on the roof!

    I've seen this issue before. The scenario of high signals on 99 but not on 103, or high signals on 103 but not on 99 is most likely due to a slightly warped reflector. You can't see anything physically warped on the reflector, but it only takes a tiny amount to affect the 99 or 103 levels. Just ask the tech to try swapping out only the reflector (only 4 bolts). It should take him about 5 minutes for the swap and then have him re-align dish again.

    I wish I had known about that yesterday when he was here. I guess I should have thought of it myself. I got an automated call last night asking me to rate the service call and when asked if the service call completely fixed the issue, I answered "No," so maybe D* will call me back for a follow up and I can ask if they'll try swapping the actual reflector. Thanks for the info.

    Just out of curiousity I ran a system test on both HR21s and each are saying I have an incorrect dish setup. Each are setup for a Slimline 5 (non SWiM) just like they always have been. The tech replaced my old Slimline 5 LNB with a new one yesterday and he said it was non SWiM - it still has all 4 lines coming out of it with 2 going to each of the HR21s. I get all my channels fine still. I've ran the system test on each before and have never seen this result.

    The code for the HR21-100 is 72-82-553.

    The code for the HR21-200 is 72-82-487.

    (Each are also saying no phone line detected but that's OK since I don't have the phonen line connected to either.)

    What do these codes mean? It's telling me to call D* but do I need since I'm able to get all my channels?

    Can you see if the LNB has three or one feed horn?
    He may not have changed to SWiM, but he could have used the SL3 LNB [single horn/LNB]

    Oh it definitely has 3 feed horns just like my old one. I'm getting signal on 110 and 119 in the signal strength screen and am getting the 110 and 119 test channels OK.

    Some observations/oddities after my experience: I just went SWM last week as part of an MRV upgrade. I did have an SL5 (5 LNB non-SWM), but we've got an ongoing issue with our neighbors trees interfering with LOS (we end up paying for the tree service every couple of years), so since we're in a 3LNB market (SF), I wanted to try the SL3 to narrow the LOS window we need (99-103 instead of 99-119), and hopefully reduce the frequency of the tree trimming, as well as the number of trees needing attention. I know the only thing I was getting off of the eliminated LNBs was EPG data, but i wanted to try everything to minimize the money we spend on the trees.

    Anyway, the install was pretty simple. A surprise is that I'm seeing about a 10 point signal boost after the LNB switch. The dish was repointed as part of the MRV install last week, so I guess some of the improvement might be from a brand new LNB replacing a 3 yr old LNB, and my tightening all the connections (although they were all pretty tight following last week's install).

    One weird thing is configuring my receivers afterwards. I assumed I needed to change the sat config on the receivers from 5LNB to 3LNB, but whenever I did that, the receivers would error out, saying they couldn't find 101. But if I clicked the "default" button, which switched it back to 5LNB, everything works great. If I check the signal strength, it's actually showing measurements for 110 and 119, which is obviously impossible. But I've flipped through most of the channels, and eveything seems to be working correctly. Has anyone else experienced this, and/or does anyone have an explanation? I'm content to let sleeping dogs lie, as long as it doesn't bite me in the butt a week or two down the road.

    Usually the installers dont use a SL3 and SWM8, they use a SWMLine3 LNB. If you really have a 3 sat lnb and your box is set to 5, your box is still going to looking for guide data on 119. I would check to see if you have a SWM3 LNB, or a SL3 and SWM8 multiswitch, and set the box accordingly. After changing the setting, reboot the box.

    I defintely have the SL3 + SWM16. I'll try changing the setting and then do a reboot, although I have my doubts- when the "no 101" message first popped up, I immediately unplugged the receiver because I thought I screwed up some cableing, and when I plugged it back in it was still the same situation. Regardless, I'll give it a try and report back.

    That was it Dave- thanks for the tip!!

    It was definitely different tonight versus this afternoon when I set everything up: this afternoon, when I changed the LNB config and hit the continue button, it ran its tests, and came back with the "no 101" msg (tried it on all 5 of my DVRs). Tonight, after hitting continue, it popped up a message saying it needed to reboot to accept the new config, and everything came up great. There must be a background process that only runs occasionally, that polls for LNB/switch changes. This afternoon, my receivers probably weren't connected long enough to detect those changes, so my LNB config change couldn't be implemented correctly.

    I just went through this last week. After d12 came on line I started having signal strength issues, this even triggered a call from D*. I told them it wasn't a big issue and to disregard, I would take care of it myself.

    Besides a drop in 103 signal strength a tree in my neighbors yard had fully leafed out and was near entirely blocking 110 and 119. Using an augmented reality app on my Droid I could actually see the issue.

    I have all HR20's and an H20 w/ the 5 LNB dish. I ran the dish setup over, selected 3 LNB after dithering the azimuth on the dish. Now it only reports the 99, 101, an 103 sats. My numbers on the 101 actually went up when I maximized the the 99 and 103.

    My 103 signal went from the 50 - 70 range to mid-90's and uppr 80's on all but one TP (a steady 78) on the 99, pretty much mid- 90's accross the board.

    I was worried about the guide data nag screen popping up, but it has only appeared once after a severe storm. So, I guess that data must be coming from somewhere else, or the 119 is still visible.

    No rain fade since.

    That's pretty sick, isn't it? I did the same with an iPhone version of it, and it was incredible!! There's still a margin of error due to the phones' sensor inaccuracies, but it's still mindblowing what they can do with the tricked out phones like Android and iPhone.

    Guide data comes off 101 & 119.
    You should get the guide data error if you stay on the channels from 103 long enough, since with the 5LNB dish, the only guide data when tuned to 103, is coming off the 119.

    So any clue as to why both my HR21s are telling me I have an incorrect dish setup since the tech swapped out my old non-SWiM Slimline 5 for a new non-SWiM Slimline 5? Should I try rerunning the dish setup on the HR21s and select the same Slimline 5 setting that is currently selected? Or should I call D* and maybe get a free upgrade to a SL3 and possibly a new reflector as was mentioned?

    72 is no phone line. Maybe this is causing some problem. Yeah I know, but I've seen weird system tests that have gone away by connecting the phone.
    82:
    82 Receiver set to SL-5 dish but a SL-3 is present. This often causes Guide Data update issues. Change ODU type to Slimline 3.

    Maybe the work-a-round here is to set it to a SL3, rerun the system test and then set it back to the SL5. :shrug:

    I noticed a yellow sticker on the new LNB so I took a picture with my digital camera and zoomed all the way in. I believe it says "SLBK4NR1-03" (I'm having trouble attaching pictures right now but hope to add them shortly). I assume the 03 refers to a SL3 but as the pictures will clearly show, it's a SL5 with the 110 and 119 LNBs. I guess I'll try VOS's suggestion and see what happens.

    BTW VOS, I took your power outage experiences (http://www.dbstalk.com/showthread.php?p=2469239#post2469239) to heart and moved my SWM PI during the LNB swapout to my office- I swapped out the standalone PI for an inline model, and plugged it into my PC's UPS. It's bad enough coddling the SWM back online after an outage, but after more thought, I dreaded the thought of talking others through the routine if a power outage happens when I'm not home!!

    So I set the HR21-200 to a SL3 and after it rebooted, I ran the system test and it still tells me I have an incorrect dish setup with error code:

    72-83-113

    Should I set it back to a SL5 and see what happens? I wish I could post attachments but still can't yet. Is is possible he installed a SWiM 5 instead of just a SL5?

    What brand is the LNB, and how many cables are coming out of it down the dish pole?
    Email your picture to davenlr@yahoo.com and Ill attach it for you.

    I'm not sure the brand. All 4 lines come out of the LNB arm and down the side of the house to the grounding block, and then from there 2 go directly to each HR21.

    Email sent to you with 2 photos. Thanks.
