I've not been receiving for a couple of days.
Having read the news, I've just switched on the system and find indeed
lower levels indicated - well, lower SQ.
The DVBWorld readout using a pre-latest GEO shop batch of boxes, I'm
getting SS 70% and SQ 91%.
Previously this was always SS 70 - 71% and SQ 100%.
And, as Ian said, the testbild channel is not active - though trying to
open it didn't freeze the DVBWorld box.
I'll put a digital meter on the downlink later to get more accurate
