Hi - Stejk

Not channels i normally view .... but just had a look here .... initially with 2.4 Channel master to overcome possible signal strength issues ... (i can only view the FTA channels) - all three transponders running smoothly .

So tried my luck with 1.2 Channel master and can receive them .. but with only a very small lock margin ... but again all view-able channels o.k. - no breakup or freezes ..

I,m viewing them with a DR HD F15 receiver .. and i,m just a little further north of you - about 25 miles inland from Lancaster .

A little less analogue, and a lot more crap.

What LNB are you using (assuming you have a matched CM feed on the dish) ?

From this site


8W is apparently showing some 6 degree off vertical, so unless a fixed universal LNB is skewed by the same amount, there will be co-channel interference from the - identical - opposite polarities.

On top of that you need to include the satellite's own skew offset, which for 8W is 3.5 degrees, the calculations are within the document below.

Hi
On the 2.4 i have the Invacom Quad C120 2- 4 lnb.jpg

On the c.m 1.2 i have a G.I. Twin universal - l.n.b.f.

Both systems are motorized .. and skew set at zero on both.

To be honest i was surprised to lock these transponders on a C.M. 1.2 this far north ... just had another look and the signal is up a fraction from this morning despite the poor weather here.
levels are pretty much the same on all 3 transponders

Thanks everyone. The problem isn't occuring tonight. I'll post some screenshots from crazy scans when it does again.

I'll have a look at the skew on my LNB luckily it's ground level so easy enough for me to mess about with.

Thanks Nelson. I used to use a Gibertini 1.25 here in Southport and similar to you the lock margin was OK but not great. Especially on 12604H which I found to be the weakest.

The official receivers are not as sensitive as my FTA recievers and TBS PC card which adds to the problems recieving the channels with such a small rain margin on the 125cm

The older Humax reciever definitely is more sensitive than the newer PVR Plus reciever and combined with the 1.5m dish I have now only the heaviest rain causes issues.
