I have been using a 4DTV (model 922) for about three months now and
have a few problems and questions that I hope some of you might be
able to address. Still have a 'sidecar' that I abandoned, but that is
a different thread someday. What I'm seeing is intermittent,
sometimes extreme, pixilation on many C-Band digital channels. The
K-Band signals (Game Show channel for example) rarely give any problem
(so I think my antenna alignment is OK). While the C-Band digital
signals are breaking up, the analog ones appear solid as a rock.
Prior to this upgrade from the analog system, I upgraded my LNB to a
17 K 'Digital Ready' device (along with the K-Band capable feed and
its LNB). Seems reasonable to dismiss the 922 as the source of the
problem since the K-Band signals work so well. With the analog at
C-Band being always so solid, I'm not sure it is the C-Band LNB. Yet,
I wonder what else it could be? I'm about to buy a new C-Band LNB.
If I was to spend the bucks and get a PLL LNB with a noise figure in
the 20-25 K range, do you think that might be a reasonable knee-jerk
reaction? Perhaps I'm missing something significant.
Signals as I can find them, puzzle me. Examples:
Game Show X4 Ch 643 -65 dBm Sig Qual 1/69 (solid)
Animal C4 Ch 603 -65 dBm Sig Qual 43/69 (solid)
HBO2E W4 Ch 10 -65 dBm Sig Qual 139/69 (solid)
Show/W G0 Ch 101 -65 dBm Sig Qual 1/69 (breaking up)
These don't make any sense to me other than I understand why HBO is
solid, being analog. Any clues from this drivel?
Suggestions would be appreciated. Thanks.
