I have a Strongs SRT 4661X satellite recorder set up by an experienced installer in April 2010. In addition to Freeview he tuned up the SBS channels which I make regular use of. The signal strength of the SBS channels proved marginal so he came back in June 2010 and changed the type of LNB for a stronger/larger (?) one. That gave us steady SBS reception for about a year, but I started to notice a gradual deterioration and last month lost SBS altogether. He came back and got back up on the roof and replaced the LNB. The Sat receiver reported 76% for SBS and continued good performance for about 5 days even in rain. And then there was a sudden drop (down to 60-64%) which in a clear sky is slightly better than marginal (56-60%) .
The installer thinks the cause of the LNB deterioration might be the current coming from the Sat receiver. I had a bit of rough run with the receiver from new – pressing the EPG button would intermittently cause the receiver to restart. After 3 trips to the service centre it came back with a new motherboard finally fixed as far I could tell.
I am considering passing the receiver to a relative in another city , but am concerned that this sort of deteriorating LNB behaviour could lead to loss of even Freeview within a relatively short time.
If there is some who could cast some light on this frustrating state of affairs I would most grateful.
