My definition of amateur radio is apparently different than yours, and perhaps my view of our world is different as well.
In my world, the slice of acceptance on 20 meters (and 15 meters) is rather slim and unwelcomed for the most part. Thank goodness for the upper 30 kHz of 15 meters.
CONTESTS ... where the WARC spectrum offers an alternative to the weekend insanity and inanities.
Throttle back to 3khz and you are only twice as wide as most SSB signals, and when the band is void of activity you should be able to exercise good judgment and operate without the threat of tar, feathers, and colorful vulgarity aimed at self and family.
We're not all running DX100's and Valiants by the way.
And finally, it should be slightly obvious to anyone listening to our spectrum, that most times 15-meters is dead, 10-meters is silent, 20-meters a zoo, and 17-meters is hopping.
Just my views ...
Strange World.
If you throttle back to some lower bandwidth, what's the point of operating an AM station to sound like enhanced telephone audio.
Some of my best AM DX contacts have been around 14.330 MHz, the upper part of 15M (anywhere from 21.410 MHz to 21.440 MHZ) and when propagation allows, anywhere from 29.0 MHz to 29.1 MHz (excluding Russian taxicab drivers).
I have never had anyone on any of those bands P&M to me about my AM signal or operating on some frequency.
As far as band activity, at roughly 30 minutes ago, 10 and 15 meters were loaded with more activity then 17 meters. See the screen captures below.
