Have to feel like if 25kw at night was doable in this market...one of the other AMs would've already tried...790, 680 or 640...but maybe those are too close to 750?
It can probably be done on 1010 in Atlanta. The question is at what cost?
To justify the capital outlay you would have to be billing lot's of money - which WGUN clearly is not. You could justify the cost....maybe....if you could create a signal which would cover the 15 county metro area with very little interference. But on 1010 it would be close to impossible.
640 and 790 could operate with much higher power levels at night IF they moved their transmitter sites and put up more towers. They would, just like WGUN, have to deal with limitations in coverage and would not cover the entire metro area.
680 already uses 8 night towers/10,000 watts and has very limited night coverage. I would bet the night coverage cume is less than 10,000 persons.
