Which begs the question: In your opinion Scott, aside WHAM, what Rochester AM has the best night signal and where is that signal's strength with regard to population? Would it be WXXI?
Oh dear God, no!
WHAM, obviously, is head and shoulders above any other AM in the market.
Believe it or not, after that I'd probably take 1460 for 24-hour coverage of the greatest proportion of the market population. The new transmitter site in Henrietta is just far enough south, compared to its old neighbors 1280 and 1370, to take in a little more to the east and west at night. Having a brand-new transmission system doesn't hurt, either, especially since I don't think there was any ground system left at the old Winton Road site by the time they left it a few years back. Also, 1460 is a relatively quiet channel here at night - Albany, Columbus and Harrisburg are all pretty good neighbors, compared to the sea of day-power-at-night cheaters on 1370 and the big WADO signal out of NYC on 1280.
I'd probably take 1280 as third, though that null to WADO in NYC costs it some southeastern reach that 1370 does get with its little nighttime lobe out toward Canandaigua. 1280 and 1370 are about equally bad going straight east and west - and straight east is the direction in which 990's 2500 watts really shine. I'm probably a little biased about the 990 night signal because even as it booms over Greece, the northern part of the city, Irondequoit and Webster, it doesn't get south of the city very well at all, even as close in as my Brighton home. (And all that incoming signal on 990 from Winnipeg doesn't help any, either.)
And then - sorry, Bob - it's a race to the bottom of the charts between 1040 and 950 once the sun goes down. Absent IBOC, 1040 probably gets a little more population in its 500 watt night signal than 950 does with its kilowatt, especially now that Detroit is cranking out 50 kW at night on 950, but with WBZ's hashmaker cranking away, that sinks 1040 almost anywhere north of the Livingston County line most nights.
I guess 1590 out in Brockport is on at night, too, but I think you have to be staying at the EconoLodge next door to hear it...
