I have issues with 28.2E compared to 19.2E and always have had. 19.2
just works whereas 28.2 is much more finicky. Last week a big storm
cloud over the Pyreneans blocked all signal for about 10 minutes - BBC2
just stopped and it is one of the better signals. During thunder storms
on 19.2 you have some artifacts but I have never lost the carrier.

That is nice. EPIA M10000 with BBC HD on DVB-S I get sound but no image.
