SbSw,

"I think it would be cool to have long wave (LW) broadcasters
in the USA. Ten 2 megawatt stations, on 10 frequencies,
evenly spaced across the country would cover the entire
lower 48 day and night."

i like that idea ~ RHF

That's absurd. A satellite covers the whole country and uses way less
energy.


Yes, and a satellite also requires a directional antenna and special
receiver (and a subscription). Putting LW into standard radios would cost
almost nothing, and add little to the cost of a portable radio.

How much energy did it take to put the satellite into orbit?
How much power is used in the uplink effort?

The actual uplink is usually in the 10 to 25 watt region for video,
and it would take less for a narrow audio only signal. An all solid
state microwave transmitter would only consume a few hundred watts. The
studio equipment would use more energy than the uplink. BTW, i have
been trying to track down the owner of an abandoned C-band video
confrencing earth station that was built by Microdyne. I want the
equipment because the system is serial number one, and the only uplink
they ever built.

Uplinks are in the kiloWatts TPO.
