That FCC site is ridiculous! Don't know who they think is looking for info there but mere mortals like me-self have a helluva time....
Anyway, try
http://svartifoss2.fcc.gov/prod/cdbs/pubacc/prod/sta_sear.htm but don't enter too much data.
Only click on whether it's AM or FM under 'Service,' then type in the 'Frequency,' and 'Community of License State.' If it doesn't return any records, try either the current (top field) or previous (bottom field) call letters (but not both) -- tho I doubt you'll have too much trouble.
When the data comes back, 'Click for Details' on the station you want and there'll be a button on the next page for 'View Call Sign History.'
Or, the regular AM/FM search query pages (
http://www.fcc.gov/mb/audio/amq.html --AM,
http://www.fcc.gov/mb/audio/fmq.html -- FM) can give the same info, thereabouts.
All you need is the 'State,' Frequency (just put the same one for upper & lower), and under 'Output,' click on 'FM Query (detailed output.....)'-- or AM Query (etc.....),' as the case may be.
When the record comes up, find the station you're looking for and click on "Call Sign Changes" -- just what you're looking for.
Good Luck,
