OK... Art Bell played a recording of a pulse type noise (buzz) bursts that
he said is bothering folks on the west coast; thousands of square miles in
extent... I heard him say the noise peaks on 7290 kHz and is a source of
irritation to coms on the 40 meter Ham band.

Anybody got the straight dope on this that they could pass along.
