    I'm getting 90s on 99ca TPN 10

    HoTat2 - How are the your other readings on D14? I am currently in the strongest part of the D14 footprint, 56.6 dBw on the footprint map. (I move, the footprint doesn't). So the strong signal may be overcoming a weak TPN 10. Los Angeles looks to be 5 to 6 dB lower. When I move next month, I will be approximately 3 dB less than it is here. The SS values start dropping rapidly once CNR drops below a certain threshold. If TPN 10 is weak at all, you would see a bigger SS difference than I would. It would be interesting to learn what others on the west coast see.

    Kyle, does 10 look any weaker than the others?

    I have 95 on the first six 99ca transponders. If you have one that low, something must be defective on your end. While LA gets weaker signals than I get here, you shouldn't see one transponder as an outlier. Since tpn 10 is on the lower edge of the 500 MHz block maybe there's a defect in your LNB's filter or something. Do you have a spare you can temporarily swap in to determine for sure if it is your LNB?

    Nope, it's near the same level as all the others. The rest range from the high 80s - lower-mid 90s.

    Right now, with the exception of tp. 10 on 99(ca), all my Ka band levels, hi and lo, on 99 and 103W, are in the high 70's to low 80's.

    Ka band was never great out west here, but then it never has to be I guess since RF is relatively rare of course.

    Nah ... no spare LNBs here right now ...

    Four output SL5 feeding a SWiM-16 and just checked receivers on both its outputs.

    All read the same as very low on 99(ca) tp. 10.

    Looks like there's indeed a problem with my install, but as a final check I'd like to hear from inkahauts or someone out here in So. Cal just to make sure something really weird isn't happening with the signal propagation on these newly activated 99(ca) tps.

    Maybe this will turn out to be a good excuse for you to switch a reverse band DSWM LNB :)

    As an additional check, maybe switch a receiver to legacy mode and connect it directly to the dish using one of the 103/110/119 coaxes? I don't see how the SWM16 could be doing this, but it would be good to rule it out. If you see no problems, try the 99/101 even coax and see if there are still no problems.

    Just for comparison, my SS readings in Northern NY last October, on the D14 TPNs live then, were all 94 to 95, using a DSWM2 RB LNB. The beam footprint contours say I am getting about the same signal strength there as Iowa, but the contours are far apart in both places. Being in an isolated mountain valley may give a better CNR, (12 to 13 dB) with lower noise around.

    This is exactly my thinking now that the initial high price of the 5D2RB on ebay has come down alot now.

    I really don't want to repair the old standard SL-5---->4 trunk lines ----> SWiM-16---->2 coax jumpers---->2 4-way MSPLITs arragement.

    And just ditch the -16 for a 5D2RB---->single line---->PI---->8-way MSPLIT install. Even though I have no 4K TVs at the moment, I still need the 5D2RB for 119W since there is no "5D2" LNB type.

    Oh well ....

    Since I was lazy and didn't really feel like crawling under the house. Just took out the DIRECTV P.P. on a 30 day free trial and had a tech. come out for the low 99(ca) tp. 10 problem.

    Then while he was here I asked if he would please just replace the legacy SL-5 and SWiM-16 install with a DSWM 2 type LNB and MSPLITER arrangement which he thankfully did.

    He didn't have any RB models on the truck nor could give me one if he had as they're only for 4K installs of course. So he ended up giving me a 3D2 as I expected as there are a lot of those in this market.

    Which I really don't care since all I mainly wanted was for him to lay the infrastructure for me to just switch out the 3D2 for a 5D2RB I ordered from ebay.

    But now guess what?

    Yep, still a low level on 99(ca) tp. 10!

    Though a better "average" level than before, but still has an even wider fluctuation now between the low 40s to the mid 70s.

    Go figure.... it's got to be something screwy going on with the signal propagation from that tp. or something.

    it would be easy to check at your neighbors with DTV subs

    Been trying for the past few days now to contact inkahauts by, PM and forum posts, who is a long time regular here and in So. Cal. like me..

    He usually responds quickly, but not this time for some reason.

    Did he rerun any wires or replace any connectors?

    Ok, just checked ...

    He used one of the old four coax runs from the prior legacy SL-5 with new connectors (though I can't see the connector at the 3D2 LNB, I would assume its new as well).

    It's the coax with messenger wire which he connected to the shell of an 8-way MSPLIT in the basement where the SWiM-16 was. And then from there to ground via the cold water pipe inlet to the HW heater.

    What are you showing on 99(ca) tp. 10?

    I just can't see how a single transponder could be weak in one geographic area. It isn't like each one has a separate antenna on the satellite, so it can't have a different footprint than say transponder 12.

    I'd say it has to be a local source of interference - i.e. not something that would affect all of LA but maybe might affect your neighbors? Is there an airport or military base nearby?

    Well I'm here in So. LA, zip 90037. You can do a Google earth on that and see that the closest airport LAX is a pretty good distance away ...

    But yeah ... this issue is starting to slip into twilight zone status ...

    Though granted no problem until DIRECTV starts moving programming to that tp.

    Interesting....

    My hr44 shows the same thing, with tp 10 very low compared to all the others. in the 30s to 50s vs all 80s on the other tps. Its on a 5 lnb dish through a swim16. So its not just you. Id ignore it at the moment myself. I think its a software glitch maybe. I have another receiver that isnt even showing signals on those transponders yet.

    Thanks ...

    Well ... good to finally know it's not just me. Strange how if it's a software glitch, it's only affecting the west coast (or possibly receivers in the SW of the country) only on 99(ca).

    Oh, and if you restart or rerun the setup on the receiver which is not showing the new tps. on 99(ca) they should appear...
