I don't remember the article, Charlie, but that's a fabulous idea, and at
first blush it doesn't sound all that hard to implement. One way might be
to
set up three receivers at different locations, each with a 10 MHz GPS or
rubidium time base (both inexpensive and readily available.). For each
receiver, a simple frequency divider could produce a pulse every 100
milliseconds from the time base. The pulse would trigger a frequency
counter, which would then count the elapsed time from the ttrigger pulse
until the DQRM signal started transmitting (or stopped transmitting -
doesn't matter which). Once the differences in elapsed times were known
between the three receivers, the DQRM signal could be accurately
triangulated. Sounds ike a fun project. Sure wish we'd had something like
that for the Navassa DQRM jerks.
I'd be interested in some project like that, but I'm afraid it would only
get to a general area. With maybe 3-10 idiots at any one time, and the 3-10
active at any time probably varying every hour, it might be pretty tough to
do anything meaningful.
Since attention is what they want, I wonder if this effort would not
encourage participation in jamming at a faster rate than it solves anything?
Has anyone ever looked to see if there is any correlation between
intentional QRM and the DX station spreading people over a wide swath of the
band? More than once, I've heard people intentionally threaten to QRM DX
because they were POed that their QSO was interrupted by a pileup.
