1. How much power does your
transmitter put out?
digital transmitter operates
at about 6,000 watts of power. The transmitting antenna concentrates
this power along the horizon, providing an effective power of 42,400
2. How high is your television
Our tower is 1,368 feet high
and was built in 1957.
3. How do you get live video
on the air?
have seven live trucks and
two satellite trucks. The normal live trucks have a microwave system on
board that transmits (2ghz) the signal back to the station via one of
our three receive sites: one downtown, one atop a hospital in north
Nashville and the other on our 1,368 foot tower.
The satellite truck operates a different way: it transmits its signal to
a commercial satellite in orbit. We have satellite receivers at the
station that can receive live programming; from there, we can send the
programming to you the viewer.
4. What frequency does WSMV
operates in a frequency
band of 192-198MHz, with a "carrier frequency" of 192.31MHz. This
frequency band was formerly known as "channel 10". However, with the
digital conversion, each TV station is able to transmit a "virtual
channel table" signal which specifies what channel we
want to appear on your TV. We have, after all, been Channel 4 for
over sixty years. We are continuing to be "Working 4 You" – "Working 10
You" wouldn't make much sense!
