On myA80J, the main satellite tuner seems to be much weaker than the sub satellite tuner when watching Bloomberg on Freesat. I noticed this when I was recording a programme on another channel and the signal quality of Bloomberg increased from the usual 58% when not recording anything (the main tuner) to 95% when recording another channel (the sub tuner). This seems very odd! The signal on Bloomberg was lost last week during heavy rain presumably using the main tuner.
