Great, many thanks all, this really helps as at least I know something is out there! I've just always found it easy enough, and only very occasional interference during heavy rain.. I'll keep trying, and maybe go on to the new LNB.. My setup is with SCR/Unicable and am sure I've always used the Satlink 'finder' on the legacy output set to "universal" LNB.. Hmmm... Yet more time spent sorting some basics while the house needs plenty of less 'basic' work! ... and maybe I'll start much earlier in the day, doing this up a ladder in full sun/30c is not the most condusive to homing in on a tiny pin point of a setting...
