The more you call CQ, and the more stations of all signal strengths you work,
the more likely you are to attract weak stations to call you.  But there
are plenty of other explanations for this phenomena than "ionospheric heating."
Another possible explanation is that the more activity there is on a
frequency, the more likely the casual operator with the small station is to
notice, stop, and think about calling in - activity generates stuff that
wasn't "hearable" otherwise.

No, actually, your original post was more than stating what you have observed.
You drew a very specific conclusion as to what was causing the phenomena.
You even referred to it as "well known."
