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....
