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....

Before working on the dish --I would suggest checking all your RG6-connections on the outside connections. Since you have a legacy system you have 4 RG6 Down leads -I suspect one connection may be damaged from water --Inspect those first.

Since you changed the LNB --It would be just as easy to change your system to a Swim SYSTEM --with a SWIM LNB --requires one rg6 --Down lead --removes your Legacy switch and replace it with a SWIM splitter --then you only need one RG6 to each HR24 .

However --checking your outside RG6 is the first order -before Messing with the dish.

Well THAT was ACE advise.  You were correct that I found a connection fault in the four-pack of RG6 that connects thru a union and then goes into the exterior wall.  Over 20 years of exposure eventually got to even a well sealed connection at the union.

I've patched it up temporarily and will replace everything between the LNB and the union with highest quality RG6 and connector seals soon.

With your advise, I did not touch the dish and it is still perfectly aligned.

Five stars!  thanks.
