Captain Jack ..last week on a 1.2m dish i got C+ Liga etc on Astra 1F ( 19.2e ) etc at 99 - 100% SNR ( which frankly I would expect ) now I get 1F at anything between 50 and 75% depending on the channell / TP . The AGC had been down around 30% and i still got SNR 99%. In any case the AGC up untill yesterday varied and had a different value on differing tps



This is seperate to the loss of 2F on the smaller dish ( though on that point down the road , its still being recieved with a 1m dish ) again pointing to something having gone wrong.

The question therefore is if the tuner can somehow partially fail . If the AGC varied as it had done up untill yesterday i would automatically assume something was wrong with the dish / lnb / cable and wouldnt suspect something wrong with the tuner itself.
