Is anyone else having problems with PBS on AMC 21? I am getting it in the evening and later at night with a strong signal, but nothing in the mornings or early afternoon. Using a Linkbox 9000i and a 10 foot Channel Master Solid.

I experienced weak and fluctuating signals on a couple (2) of the Horizontal transponders this past weekend. The Verticals were fine. I have not checked since yesterday.

AMC-21 12180 V 30000 is strong here on a 10' Mesh Dish! Around 75 quality and also on my 1.2m KU Band Solid Offset the same. The Montana 11919 V 2397 low fluctuating in the mid 50's but playing fine. My Azbox is reading in the mid 70's on the 12180 V 30000 and the Montana 11919 V 2397 is reading in the mid 60's on quality.

I haven't seen much change here whenever I go to AMC-21. I've got a fixed 1m dish with an SL2PLL LNB aimed at 121, feeding a WNC SWA-48 switch.

I see exactly the same thing on PBS AMC 21; Good signal in the evening and weak or no signal in the morning and early afternoon.  For me, it's been that way for several months.  Same results using two different receivers with a 1m dish in Las Vegas.

Thanks Jim

Apparently there is different power in 11916 montana pbs depending on the time, with antenna 10 feet low to 50 of quality in the morning;
Dish 1.2 sometimes is not; 12180 is powerful

Yes through the years I have seen these feeds go up and down! I have seen Montana super strong at times and the 12180 down. I'm just happy to get them to play whatever the signal or quality level.[biggrin]

Thanks guys, just wanted to make sure it wasn't me or my equipment.

If you're talking about the horizontal SCPC transponders (12145,12155,12163,12169,12175), yes those transponders vary quite a bit because they are uplinked from a variety of different locations. Also, I've seen the 11916 V Montana transponder vary quite a bit (for unknown reasons, but I'm guessing it may be related to nearby signals).
   But if you're referring to the two transponders uplinked from PBS in Alexandria Va, (ie 12120 H and 12180 V) I have not seen much variability in those 2 transponders.  About the only times I've seen 12180 vary in SNR have been related to strong storms in the northern Va area.  All other variability I've observed has been traced to problems with my system, most commonly the trees that have grown up to where they are partially blocking my signal.  In the winter I get excellent signal due to no leaves.  In the summer the signal drops 2 or 3 dB of SNR, but is still strong if the leaves are dry, but if the leaves are wet, it drops even more.
   The one strange thing I've noticed is that if I peak polarity on 12180, then the horizontal transponders aren't quite as strong, and if I peak polarity on the horizontal transponders, then the vertical 12180 isn't quite as strong. I tend to blame this on the fact that AMC-21 is relatively close to the horizon forcing me to view through tree leaves, although I really don't know why that would be.
   But anyway, I haven't ever seen variability in 12180 that I could attribute to power issues with the uplink. Everything has either been local issues with my system, trees or weather, or storms in Virginia.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
