is something wrong with the national PBS Ku feed?

It's barely showing up at my location, won't stay locked for longer than a fraction of a second. All other transponders seem strong.

Looks fine/normal here in NM

12.2 dB here. Pretty normal. About 0.7 dB lower than Montana PBS.

 

[Jim S.]

Well then I have no idea what's going on. Montana and the NBC transponder are stronger than I've ever seen them, so I can't imagine it's an alignment issue.

Weather (rain) related affecting upper frequencies? There are some wicked storms playing out in places. The storm doesn't have to be over you necessarily.

 

[Jim S.]

This afternoon I'm getting it at 7.7dB, which is a lot more than yesterday (almost no signal) but not enough to lock it. Occasionally it'll jump to over 8dB and lock for a few moments. I don't think there are any storms close enough to block the signal, and if they were blocking it at at the uplink it would be going out for everybody.

This morning it is 12.2 dB now as last night. Montana PBS is 12.9 dB.

 

[Jim S.]

I guess my alignment was off after all. I moved a few clicks west and now it works. Funny that it doesn't seem to be affecting any other satellites though.

I find on 99W that after I peak on Montana PBS or PBS that I must bump the dish two bumps to the west to peak the Nexstar channels.

Same phenomenon on 101W C. METV is peaked a touch to the west of other tps. Once you know then no problem.
