The wullenweber at the USCG electronics lab in Alexandria va (K4CG) was available to any government agency Who wanted to use it. It was used by the Navy, the USCG for search and rescue, the FCC and we had other Agencies come there who never actually identified what agency having made arrangements with the commanding Officer before coming out.

They also advertised their calls so it was probably easy to track then. It's different if a DQRM'er is on sporadically and on different frequencies. I thought the Wullenweber was use by the Military, not the FCC.

IIRC, one is (or was) on the east coast. AFAIK, the Wullenweber is not used anymore by the FCC and is scheduled to be (or already has been) replaced with a different --and far less complex-- antenna. One thing the FCC uses their newest HFDF system for is to pinpoint the source of some idiots who make a sick hobby out of QRMing, for example, 14.313. There are remote locations all over North America. The FCC claims --and I believe them-- that they can use that system to quickly triangulate an HF transmitter's location with a very high degree of accuracy. >From looking at the PDF I referenced earlier, I'm not certain that all the remote locations are in operation yet. The last one appears to have a completion date of sometime later this year. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
