I have FIVE 50kw transmitters within 30 miles of me (daytime). I also have a 10kw transmitter within 5 miles of me (also daytime). Four 50kw transmitters within 30 miles of me at night, (WYLL moves to a site farther south, and 10kw WNVR either signs off or turns into a 130-watt pumpkin.
In the reverse, i have no AM transmitters within about 180 miles! KNSA 930 Unalakleet is about 180 miles to my NW with 5kw full time and KAGV 1110 Big Lake, AK with 10kw full time is about 180 miles to my SE. KYUK 640 i think is a bit farther and to my SW... then the next nearest is fairbanks, 250 or so miles NE
