Since this the first time I've seen a similar phenomena, I can't draw
conclusions. I might have to set up a receiver with ber and signal level to
be on constant standby.
I have to say that I'm not sure at this point if the problem is in the
receiver, the modulation or interference. I think it's safe to assume that
not all DTV signals in southern California went out at the same time.
At this point, the house of one of my brothers was near the fire area, but
appeared to be okay as of this morning; another brother was just barely
outside the evacuation area, and my mom had a bit of a scare this morning,
but those flames never got closer than about 5 miles.
As a native southern Californian, I have long had the "smell of brush fires"
wired into my DNA: I go into action at the first hint of a smell of it. The
worst part (for me) of this whole thing is living, breathing and smelling
that smell every moment of the past 2-1/2 days. Sure, the ash was heavy and
it was hard to breathe on Sunday afternoon. Imagine a three-day wind-fueled
adrenaline rush. The smell has abated somewhat, but it's still there.

Glad to know you are not immediately affected by the fire, except for
DTV reception.
What you describe below is exactly what I have written about for over 5
years.
The DTV images drop out for a few seconds to 3 or 4 minutes and then
reappear, but
the dropouts continue daily on all digital channels. I cannot watch or
record a sports event and
get any satisfaction of knowing what happened throughout the game.
The conclusion I draw from this is that our present DTV system does not
replicate
the coverage provided by analog NTSC.
