>> for a amateur DTV exciter. What tiny amounts of DTV activity there are
> We have some ATV in this area and it's expanding into the public service
> area working with the EOC. This is bringing up some interesting portable
> antennas as we do not have either the space or budgett for those "microwave
> dish on a pole" setups the TV stations use.
> I'm working on an idea for a *relatively* light, trailer mounted tower. It
> only needs to hit about 30 feet.
>> an obsolete (but cheap) satellite TV receiver using a modulation
>> incompatible with the format used in the U.S. for terrestrial

>> every TV being sold with a digital receiver, a great potential resource
>> amateurs, but useless because there's no amateur 8VSB transmitter hardware
>> out there.
>> There WAS a source for DVB-T and DVB-S gear for experimenters and amateurs
>> in Europe, but last I checked, they had gone away.
>> Really too bad.. But hey, NTSC analog AM ATV will just be yet another
>> archaic mode preserved by amateurs as an interesting hobby and curiosity.
> They wan't to get a portable repeater set up for it here, hence the work on
> the portable towers that are easily set up. Of couse they can be used for
> Field Day too. <:-))
