ARLA/CLUSTER: As emissões de ATV vão ser efectuadas em formatos digitais e em Alta Definição pelo menos na California

Ham TV operators go high definition

The TV Technology site reports on amateur radio experiments with QAM and
DVB coding

*Mike Collis* is one of those HD adopters. He’s a California ham (station
call sign *WA6SVT*) who’s been involved in amateur TV since 1976 during his
high school days, and recently ventured into high definition. (He’s also
transmitter supervisor at a commercial television operation.)

“I moved into high definition about two years ago,� Collis said. “The
incentive was the higher clarity pictures.�

Collis is in a fairly unique position in terms of keeping track of the
segment of the amateur operators involved in television, as he’s
co-publisher of Amateur Television Quarterly, a niche publication dedicated
to news of amateur TV experimentation that’s read by more than 400 hams. It
was a report of HDTV experimentation by a fellow ham that led Collis to
make the shift to high definition.
