I'm in Southern California. No Canadian station on 1610 is going to make
it into L. A. at 9:30 in the morning.

You're probably right.. but not necessarily. During winter (especially)
AMBCB stations can be heard at very great distances, even in the daytime.

Two examples of such:

580 KFXD Boise/Nampa, ID heard all day, all winter at Astoria, OR, for most
of the winter.
620 KGW Portland, OR heard for several hours during a snowstorm in Lewiston,
ID
610 KONA Pasco/Kennewick/Richland, WA heard most any time in the west hills
of Portland, OR (with 5000W KGW on adjacent 620!)

Doesn't prove anything either way, just fun facts.

I had never seen TV skip until I was 19.. when I was watching local channel
2 (KATU) in Portland and over the span of a couple minutes I ended up
watching the news on CKCK channel 2 in Regina, SK, Canada. RF is black
magic..

The third example was added as an afterthought.. since the station is only
about 200 miles or so distant..

One thing that I will most most after the DTV transition is VHF TV skip;
I still have (nighttime) dreams about TV skip. I imagine that the
signal management controls in DTV rcvrs will simply disable display when
confronted with skip. Any thoughts?

Skip will be a lot more of a challenge, especially since the number of VHF
channels will decrease, but it will still be possible. As long as the
systems are compatible (US/Canada/Mexico), the television won't care a whit.
Capture effect may work even better than it does for analog. As with analog,
though, open local channels would be easiest.

The receivers aren't that smart. TV will still skip.

There's been some discussion in the DTV groups (alt.tv.tech.hdtv,
alt.video.digital-tv).

There's a threshold effect in the reception, so if the skip is stronger
than the normal transmission by that amount, I'd expect that will be
what you get. If the tuner were too picky, people who get marginal
reception wouldn't get anything at all.

Turns out that you can park your set or converter box on a channel,
a lot of the units will pick up the PSIP(?) channel data and save it
in the channel table, so you get an automatic ID. About a third of the
local (Seattle) stations are hopeless for me to get reliable reception.
But if I know their RF channel, I can set my converter box until a
plane or ship goes by and pull the channel ID out of the ghosts and
check later to see what subchannels they have running. (Hmmm, PAX and
the Sportsman's Channel, well, no loss).

Lightning and other impulse noise are bad news for ATSC, so most
of the stations didn't stay on low VHF, where it's the worst.
