As 10 meters began its decline a few years ago, I would often ask AM
operators if they ever used 15 meters. With very few exceptions, the answer
would usually go something like: "No, because I never hear anyone else down
there."
There was AM activity for a brief time around 21.400, and on 21.430. But, in
casual tuning on the weekends, I have heard less than 5 AM stations on 15
meters within the past year.
I say all that to ask just where is the "AM window" on 15 meters?
And, why don't more of us operate there?
Unless there's a contest, 15 meters is usually not crowded. Those of us who
run rice boxes or similar power can usually hold our own there once a
contact is established.
