MW stations have been legally broadcasting in the so called X band from
1610 to 1710 since about 1997.

Even though I am about 100 km from the nearest MW transmitters, almost
anything I do that isn't a good connection causes all sorts of IM products.
It's a constant battle! Fortunately many of the small whisker diodes
that cause the issues are destroyed while transmitting, so while the band
may be full of products at the start of the contest, it quiets up once you
start transmitting. But they start growing back after the contest....
