WHK comes in in the daytime in Southeast Michigan. When you get North of Pontiac, WFLT (legacy call letters WAMM) comes in. WFLT has an amazing signal for 500 watts and a high dial position. It is located in a clay loam creek bed. You can hear it all the way up to Houghton Lake and Oscoda on a good Delco car radio. At night, WHK is the one you usually hear when WFLT is off, and when it signed off at night. Due to a relatively high NIF, many stations have been heard. WIMS, WOC, KTOE on day pattern, and even WPLY Plymouth, WI (whatever their call letters are now) is occasionally heard at dusk. WKPR Kalamazoo could be heard at sunset, but has moved to 1440 now. Due to the 310 degree maximum of WAMM/WFLT and wide beamwidth, much of the pattern to the West and North exceeds the equivalent of 1000 watts. I once heard in in the Northwest suburbs of Chicago just before sunset, but I didn't realize that it was possible then with 500 watts and didn't stick around for the ID. I heard an ID for WPON 1460 Pontiac at the same time and wasn't that surprised since it was 1000 watts nondirectional days at that time. But WAMM/WFLT radiated just as much in that direction as the minimum efficiency WPON did with half the licensed power.
