    I have in 99(ca) from tps 9 to 24 tps 98% of signal(in Miami)

    Yeah ...

    The anomaly with 99(ca) tp. 10 seems to be out west here somehow.

    Maybe there's a spot beam broadcast to the LA area on RHCP just below 19.7 GHz, and it is spilling over slightly into the range of that transponder? Anyone know what the spectrum just under 19.7 GHz is allocated for?

    99ca TPN 10 is on 19890 Mhz, LHCP. TPN 9 is on the same frequency RHCP. immediately below them 99s TPNs 7 & 8 at 19850 RHCP ,and LHCP, from the same satellite, D14. TPN 8, which has the same LHCP as TPN 10, has 9 spot beam transponders, and the closest is in Oklahoma and Kansas. Since you asked about RHCP, The TPN 7 spotbeams get as close as Utah and Abilene.

    But we have no idea what they did with Spaceways 2, whose upper transponders interfere with 99ca TPN 9 and 10 as well as the spotbeams. If, for instance they are using them for a spot to South America, a sidelobe could conceivably interfere.

    Duh, in my head I'm thinking tpn 9/10 are the 'first' in the block but they are only first in CONUS, not first in the 500 MHz block. So it can't be interference from other bands.

    Can't be from another satellite, Directv's 101 satellite uplinks in Ka from LA, its spot beams are elsewhere. Given D14's position at 99.235 or whatever, even if there is a Ka hi satellite at 97* it seems unlikely it could interfere.

    Very curious. Maybe HoTat2 should drive by Directv's HQ, knock and the door and ask them because they surely know! :D

    Gary tells me he is seeing the same problem in San Diego, with wide swings in the SS readings on 99ca tpn10

    My low reading on TPN 10 is 62. But the SS bounces around every 6 seconds when the screen values are repainted. So it bounces all around between 62 and the mid 70's.
    Very strange...

    What does it look like if you use the signal meters option to focus on that one tpn? Is there any pattern to the changes or just bouncing around in that range?

    Maybe it is a sign of seismic instability and SoCal is going to break off the mainland and become an island! :eek:

    anyone with spectrum analyzer there in SoCal ?

    If there isn't a fix for it, I suppose that transponder would be a good place for Directv to put all their infomercial channels! :rolleyes:

    Just checked ...

    Signal meters bouncing and irregular beeping of the audio feedback as well.

    Though the percentage measure used by the meters shows a much smaller variance than the level indicators with the tuner level bars fluctuating between about 56% to 60% on the problem tp. ...

    I wonder what the range is? Someone could take a poll in the CE chat some Friday night to figure out what everyone's 99ca tpn 10 is to see how large of an area is affected and if it falls off slowly or there's a fairly sharply defined geographic area.

    I wonder if it is possible this interference is a harmonic, so it isn't originating from 19890 MHz but half or quarter of that frequency?

    There is no pattern to the SS changes. I expected to see a stepped ramp-up and then a ramp-down. But no. The values just jump around. The single consistency is that the value does change with every 6 second repainting of the SS screen.

    Just saw this thread, as soon as the Superbike race is over I will check here in Denver

    The issue is not going as far east as Colorado. Tpn 10 has been 93 or 94 for 2+ minutes. I did have to restart the receiver to see the transponder

    Yep, something really weird going on out west ...

    Gone through 3 LNBs in about a week now.

    SL-5 legacy - issue was first noticed...

    3D2 SWiM LNB - level on tp. 10 a little better, but same low and fluctuating issue.

    Now using a 5D2RB - Same behavior on tp. 10 as with the 3D2.

    Definitely is a problem on DIRECTV's end.

    any chance to do Select Signal Meter on tpn10 and find a rule of changes (sinus ?)

    I don't buy that. I can't see how Directv could be responsible for having a single transponder lower in a limited geographic region. It has to be some sort of local/regional interference.

    Interesting that it seems to affect LA more than San Diego. I wonder if LA is the 'epicenter' of this issue, or if it is worse further north like San Jose? Anyone from Las Vegas who can take a look?
