Although I wouldn't rule out receiving European (Icelandic?) PAL and/or DVB-T broadcasts from
Europe on some of the Lo-VHF channels if you are located in far-East Canada or Maine, it's very
unlikely....ditto for receiving South American (perhaps some Caribbean islands?) broadcasts in
the southern U.S. states, esp. in RURAL locations via Tropo Duct or other modes of propagation:
Note that many TV-DX reports are for hearing the audio FM carrier, a few actually see Video.....
Sporatic-E long-range VHF propagation mode is sometimes available (Todd is in Australia):
And there is UHF Moon Bounce propagation mode for extreme range fanatics:
Immigrants in North America mostly can receive 50 Hz formats via either DVD or C-Band Satellite.
There are many DVD players that convert PAL discs for NTSC output, but only a few that are
"Region Free", rather than "Region 1" for North America ONLY. [Google for some hacks....]
I presume PAL on SAT requires a PAL compatible TV unless conversion is provided by SAT Receiver.
Of course, you would need to be line-of-sight to desired SAT: http://www.dishpointer.com/
C-Band programs for each satellite can be found at: www.lyngsat.com
Unfortunately, it isn't easy to determine whether the "A" (Analog) symbol means NTSC or PAL,
so consider where the material originated....
As Stampeder sez, ATSC A/63 is a dead standard....Google search does not reveal implementation
by any of the chip manufacturers....nor did I find A/63 in the several old spec sheets I looked at....
BTW: Several years ago, while stationed in Italy, my son-in-law bought an HD-RPTV which supported
both NTSC (on-base AFRTS) and PAL (local Italian broadcasts). But since the military on-base systems
have not yet been upgraded for HD, there is no market for a multi-format HDTV (NTSC, QAM & DVB-T).
AFRTS (Armed Forces Radio Television Service) employs Satellites, on-base cable systems and (in a few
foreign countries) On-Air NTSC transmitters to provide television programming to U.S. service families:
List of FM and NTSC On-Air transmitters in foreign countries:
I wouldn't be surprised if they convert OTA from NTSC to ATSC sometime in the next several years,
but FIRST they have to convert SAT distribution system to HD...beginning in 2012:
So other than a possible future AFRTS ATSC transmitter in a foreign country, where would anyone
ever need a dual format ATSC & DVB-T HDTV????? The market must be vanishingly small.....
It would make more sense to use an external DVB-T Tuner box with an ATSC HDTV (or vice versa).
