Ah, that makes sense. Your original point is true though about the translator's signal reach. There is a tendency to think these translators will be able to compete against the big guys but listeners on the outskirts aren't going to put up with such an inferior signal.
I think actually that 97.1 has the best translator coverage from way up there on Bluff Mountain. Can you imagine what their signal would be if they were the full 250 watts?
I was just looking at 97.1's coverage on Radio-Locator. Looks like they have a CP to move the translator to Sharp's Ridge & power up to the maximum 250watts. Not sure if it's moved yet or not, but this should put their signal/reach pretty equal to that of 107.3 & 99.7 as far as Knoxville proper coverage. Seems like these translators on Sharp's Ridge do ok, but not great. With Knoxville's hills & valleys & sprawling suburbs, coverage w/ a single translator is difficult. Seems like the Sharp's Ridge ones cover downtown, north Knox, & the near west suburbs decently. But once you venture out past say West Hills or C Bluff, they get spotty. Probably, optimal situation would be two translators (Sharp's Ridge & one somewhere in west Knox Co).
