Certainly do.

It was particularly bad in the 40m and 20m bands (I was in the UK at that time).  It was said that if you put your keyer dot rate to the right speed and transmitted a string of dots on its frequency, you could interfere with it enough that it would then move frequency, hopefully to another band.  I remember trying this and it did seem to work most of the time.

Remember the pulse on the HF bands in the 1980s?  It was deafening, all over the world!

BBC Horizon show (1982) investigates the “Soviet Woodpecker" electromagnetic signal, a 31-bit binary with 10 Hz repetition rate transmitted to many countries worldwide

 

 

A shortwave over-the-horizon radar? (Detecting targets at very long ranges, beyond ordinary radar horizon).
 

Linked to mind control and behavioral modification? Dr. A. Michrowski says it is a signal of same frequency range and same type as brain signals.

 

On the hypothesis that the Woodpecker Radar signal had a biological bio-product
Three repetition rates: 10 Hz, 16 Hz and 20 Hz.
"The most common rate was 10 Hz, while the 16 Hz and 20 Hz modes were rather rare."

 

Protective transmitter (magnetic jammer) of German diplomats operating at 7.8 Hz overrides (jams) the Woodpecker signal (image).

 
The episode can be found in four videos of this YouTube playlist:

The relevant video is part 3.

The darned woodpecker signal would move up and down the bands, ham bands, military bands, marine radio bands, all of it.

Even CW had difficulty getting through.  However, we stuck with it and kept repeating what we needed to and the message got through.

Do any remember this?
