Far northwest limits of the Chicago Metro.....
Day: WSQR from Sycamore, IL. Fair-good signal
Night: WHAM with a good signal. Sometimes mixing with Cuba. Worth noting that it used to be WHAM all alone, but as David has noted. the Cubans have upgraded their AM transmitters (with a major assist from the Chinese). It would seemingly stand to reason that this explains why Cuba on 1180 is no longer a rarity. Certainy WSQR dropping to ONE watt at night is a non-issue.
Sunrise: WSQR seems to have a habit of powering up before local (or even Rochester) sunrise. Day power is 900 watts. Not sure if they're going all the way up to that point, but the result is WSQR and WHAM end up at almost equal strength here.
