"This looks like a job for LeeRoyMan--aka Dave Montgomery. He would be the most clued-in of all of us to explain the weak signal.
My pet theory is background noise. KAAY is not alone in having diminshed coverage. There's a 5KW on 670 in Glenwood, 35 miles from me, that I cannot pull in. There's another 5KW on 590 in Hot Springs, roughly 30 miles away, same story. There's a couple of 1Ks within 10 and 15 miles, respectively, that might as well not be on the air.
My take is that the amount of electronic intereference to AM has grown exponentially with the increase in computers, cell phones, garage door openers, vacuum cleaners, Skil saws and Lord knows what-all else over the past 20 years.
Felix McDonald used to claim that even leaves on the trees in springtime and summer would interfere with KAAY's coverage, and it's commonly accepted that nobody knows more about RF propagation than he does.
Dave M will be The Man on this issue.
When I knew Russell Jones, he was the sweetest, gentlest kid you could imagine. All he wanted to do was work on the air. I do not know where he is now, so if anyone runs across him, tell him I said hey!

I agree, David...Leroy IS The Man! I also agree on foliage and man-made interference. Being a Ham radio operator, I can attest to the fact that foliage can and does affect my transmitted signal. I won't go into all the details. Man-made interference also diminishes the capability to receive signals. I am so glad I live out in the country, where there is little said interference. Due to consumer-grade electronics in my own home, I only have noise on a few select frequencies, thankfully, but for the most part, my location is almost totally noise-free.
As for Russell Jones, he's now on the "wanted list" for contacts and comments for the blog....
Thank you, David!
