771 on a legacy system in Phoenix
Its a house well-mounted SL3 dish which has worked perfectly for over 25 years. a multiswitch drives three different HR24 receivers.
The dish is aligned nearly perfect with very high signal strength across the board. The 771 is being triggered apparently by the 103 ca and cb signal being intermittent: on either page the strength bar can show 86 for a few seconds and then disappear for a few seconds. Both channels display this behavior. which certainly is the cause for the 771 fault. Selecting a different sat 103 transponder fixes the intermittancy, but the transponder assignment wont lock - its always back on the faulty transponder 1 when you return to the page.
I've replaced the LNB with one I know works. I have not moved/tweaked the dish yet, that's the next step. What's happening here? it's also as if the 103 sat has moved....
