John, we don't have the budget for a new AMT, but after 15 years in the format I have research (including WMJI AMTs from years past) that is very useable, especially for an AM station. Let me stress that I am not a research "tactician". Hate research on the whole. Garbage in garbage out. It can be manipulated easily. I don't just plug in POP scores. Don't believe in it.
You've got to know the demo and their lifestyle, the music, the market, etc.
Ex:The "At The Hop" 50s/60s show I hosted at WTRG/Raleigh, a market with a median age of 42, garnered a 21 share VTK'd P35-64 (the true oldies demo, not 25-54). I know the music and what the demos want to hear. In Raleigh, I also knew that the major influx of those migrating to the area were from NYC, Jersey, Boston, Pittsburgh, Baltimore, Philly and even Cleveland. Doo wop, R&B etc all big in those markets. I was told the show would flop... it eventually became Top 5 P25-54 when it went to a live show, able to take requets and add features that required live calls.
Me personally? There's a lot of tunes I can't stand hearing. But you can't program what you like/don't like. And you can't use Whitburn's Top40 book to program either. Lots of songs were "hits"... but are really secondaries or even oh wows.... payola tunes really. Powers win. But we do work in tunes that WMJI hasn't (won't) played in a long time due to the demos they're now after. .... We're doing what we can with the available time given for music.
I can say this... WAKR has evolved exponentially since June. Lots of music on the air now that wasn't just eight months ago. It's a process.
With that said... there are songs that fatigue. Brown Eyed Girl, Unchained Melody, and others. But they're also "Super Powers" as far as POP score goes. So we play them, just not as often as you normally would.
We have an ever growing library.... my 25,000 song HD
As for the signal... I'm not an engineer.. and never really got into it enough to speak about patterns etc. I do know that we change pattern like a daytimer signs on/off, depending on the month. In the summer I take 'AKR on my drive home as far as Elyria... sometimes further.
