Great news VSSo ...
I'm thinking all my hard work has paid off ..
Preliminary tests with the modded SL3-03 on the 1m Orbital with the new mount ..
Newsnet locked at approx 11db ..and no tweaking at all ..
just had to set the usals to 20.2E ...and bobs yer uncle ..
Easily as good as on the 1.5 ...but then I am at the focus (more or less) of a 1m ..as opposed to about 6 degrees off focus on a 1.5 ..
BIG difference ...and with some tweaking might yet get more..

Wont be able to try till tomorrow ...Has that solved the BER problem? Great going
Maybe not the same, but that could well be something similar I had with my SL3-03 VS, when I had to place a brass ring slightly skewed across the mouth of the feedhorn on a Triax dish, which was aiming correctly at 19E.So ...

Now ..fwiw This is what I think ..
probably no logic to it ..But..
here goes ..
11.2 db on the new setup ....Newsnet Locked ..and fairly fluid movement wise..
11.2 db on the 1.5 ..but offset ..Same signal level ..but only occasional lock..
??
makes no sense ..OR does it ?
Maybe 8PSK signals in Ka dont like to be skewed (not arriving at the same time) ?
IE the signal not coming direct to the feed..
at these ultra high frequencies ...signals arriving slightly staggered due to the skewed offset angle..
could these signals occasionally cancel each other out causing the errors I am seeing ?
We do know that dishes are precision made at these frequencies ...and setup of internet by satellite is a more precise art form..
So ..could this be a factor ?
I'm now thinking it could well be.

Certainly I could see some similarities there Llew..Maybe not the same, but that could well be something similar I had with my SL3-03 VS, when I had to place a brass ring slightly skewed across the mouth of the feedhorn on a Triax dish, which was aiming correctly at 19E.
Perhaps the feedhorn to my Triax dish area wasn't truly compatible, unlike with using a DirecTV dish?
That's really good news :-)..Newsroom changed to feed ..
which I just watched without a single glitch..
and this is with a cover on the SL3-03 ..which will always reduce the dbs by approx 0.5
I'm currently a VERY happy bunny..
Correct me if I'm wrong, but weren't you considering giving up on these LNBs?..Newsroom changed to feed ..

Yep ...rub my nose in it buddy ..Correct me if I'm wrong, but weren't you considering giving up on these LNBs?
So ..
5:30 in the AM and normally I wouldn't be aware there were 2 x 5:30s in a day ...but the cats just woke me wanting to go outside ..
Took the opportunity to check on the Newsroom ..
Yep ..still there ..
signal now at 9.7db ...whereas last night left it at 11.5db before going to sleep..
Now we are back to occasional freezing and glitches ...which is what I'd expect from past experience..
If memory serves ..the magic number for me was 10.4db
but still am Impressed with how this is holding up.
C U later ..
back to bed for another hour or so.
