Sunspots create extreme electromagnetic signals, strong enough to swamp
radio signals,
AM, FM, TV, satellite (including for cable TV), and microwave relays.
Worst problem is  when the sunspots power path is in line with the intended
radio signal.

This fits the "law" of the biggest bully (sunspots)  making the little dude
(normal radio) hide.

So, when sunspots are at a minimum, radio has least interference from them,
thus DX'g is best, cable satellites get least interference, etc, etc.
