I just discovered this thread since posting over on the
antenna thread, so my post will be pretty similar to one
I made over there.
(Last wk), I hooked up a Samsung tuner (SIR T351) to an
antenna and pointed the antenna towards Southfield. I live
in Ann Arbor, so it is about 60-70 degrees E of N for me.
The antenna rests on the studs in my garage. I am using a
Radio Shack amp about 3' from the antenna hookup. After
monkeying around w/ the antenna position, I now get all the
stations in that set of Detroit stations (7 HD and a handful
of SD's too). There is a "signal strength" meter on the
Samsung tuner and every station gets either 8 or 9 bars (of
10). And every station comes in crystal clear except ABC,
which has periods of block-like artifacts and also "no
signal" stretches. What is weird is that the block-artifact
periods sometimes come even when the signal strength is
hovering at 8, and sometimes there is this abrupt drop to
zero, and that is when the "no signal" message appears.
None of the other stations seem to have a problem when
the signal strength is at 8.
Is anyone else seeing problems like this w/ the Detroit ABC
station? Or could my hardware or tuner have some bizarre,
station-dependent problem ? Gotta fix this by the time
the Rose Bowl arrives
