AMC 1-Ku on a 90cm?

[chadg2]

Are the NBC's on AMC 1-Ku impossible to get in on a 90cm using a Spitfire Elite? I'm -26 off on the skew and can get the north and south pier solid, but can't lock on the NBC's. I get them on my 10 foot dish with the skew set at zero, so I thought I would get them on a 90cm with the skew set properly. Any suggestion, or is the dish too small? Location is Wisconsin. Thanks.

I havent tried recently but could get the NBC stuff on a 76cm dish

make sure its skewed properly.....26 skew opposite of what it normally would be so for me in Minneapolis its -16 for the skew to set it at
The vertical side of that satellite is real easy to get those TP's (the pier) but horizontal side is harder because the power on those transponders is lower than normal. Its not like a NBC affiliate is using a 90cm dish to pick them up

using my meter I can get bursts of full signal strength on the NBC transponders, but they drop to Zero and back up to full signal in seconds. Can't lock and keep them locked.

The NBC's are DVB-S2 (not DVB)

Warped reflector?

It is said that the Spitfire feedhorn is too short for some installs to optimize the FD. Have you tried a different LNBF?

Could be a threshold signal. Poor quality LNBF? Drifting LO? Tweak the frequency? Tweak the Symbol Rate?

It's a GeoSat Pro Brian. No I have not tried a different LNBF, but I know this one is good. I just bought the dish from you and got it on Tuesday. I have a few other LNBF's I could try. I didn't try the bullet, because it's the funniest looking LNBF I have ever seen. Thanks for the help. And the meter is a DVB-S2 meter Iceberg, the one I won from SatelliteAv. It works good by the way. Thanks again.

I get them about 60% quality on a primestar 75e dish and stock lnb
