If you did locate the offender what would you do? You could report him (or her) to the FCC but the FCC would probably not act until they could catch the offender in the act.
These DQRM offenders act sporadically so it would be difficult to track them down. What is the offense? This is not interference in an emergency or health and welfare situation but to a station participating in a hobby event which itself is using up tens of kilohertz of spectrum for the act of working a "new country".

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. 73, Jim W8ZR > _________________ Topband Reflector Archives - http://www.contesting.com/_topband
