Some clarification: KDOK was on 1490 in Tyler from the late 50's to the late 80's when it was a popular Top 40 station and later satellite oldies. Then in the late 80's those legendary calls were ditched for KYZS and ESPN Sports.
Then the KDOK calls moved to 1330 (the old KZAK, KTYL-AM and now KGLD) with standards. In the early 90's those calls moved to 92.1 continuing the standards format, and then local oldies for many years until two years ago when it became news-talk KTBB-FM.
Then Townsquare moved the KDOK calls to 1240 in Kilgore running "True Oldies". The signal covers Longview fine during the day but has a lot of problems at night, about a 10 mile signal at best. It's a 1000 watt station built for Kilgore, and it's dumb to think they'll get any ratings with old skool R&B and Hip-Hop... on AM?
