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?


How much energy did it take to make your plastic shortwave?

Probably about 0.00003 seconds worth of rocket burn.
