This is a current ATV project I am working
on. The pupose of the system will be to transmit local
weather conditions super-imposed with video from tower
mounted camera. The system is brought up with the
presence of a tone encoded 2 meter FM signal. The output
is from an horizontally polarized antenna array using a
frequency of 421.25, allowing anyone with a cable ready
televison, tuned to cable channel 57, and an outside
antenna to monitor the system. The 2 meter audio is mixed
with the atv signal so that any licensed ham can use the
system. This also has the advantage in allowing users
that noramlly can not talk to each other simplex, because
of distance, to now comunnicate with each other. The user
has the choice of disabling weather information, panning
or tilting the camera, and at times of severe weather
activating warning messages. I have hopes in the future
of adding a voice to the system to vocalize the current
weather conditions and repeater operation to aid sight
impaired users and listeners. Currently the system is
still in the designing stage with hopes of having it up
and running by late the summer.
