Its nice to meet another Old Crow, on the reflector. I did 8 years in the  
U.S.A.F. in ECM repair, everything from B-52's  to F100s, F4c, weasels, and  
the 
odd  stuff we still can't talk about.. ECM , where Jam It takes on a  whole 
new meaning.

When the  Soviets were running OTHR in the amateur bands, (which used the HF 
echo to  "see" targets) I used QSK CW dits to synchronize with their OTHR 
pulse timing  and jam their "B" scopes. As a former Radar Electronics 
Counter-Measures and  Electronics Counter-Counter-Measures operator, I knew it 
was simply 
a matter  of transmitting a signal of about the same frequency, duration, and 
slightly  stronger than their "return" to confuse their operators. By setting 
my keyer  speed so that I did not hear their pulse while QSK at 100 W and by 
calling  HH5HH with the beam pointed at the strongest OTHR signal, I'd usually 
hear  them go QRT or find someplace else to play. Calling HH5HH QSK at the 
OTHR  pulse rate worked well until the Soviets started using digital signal  
processing, then it became a "overload signal game" with less apparent success  
in 
forcing them to QSY or QRT.

By the way my RADAR set back then was a  Ten-Tec OMNI-D....
