Is anyone using this DQRM Tracking Project report? They want reports of deliberate QRM like 'tuner uppers' and other types, but not QRMers like cops or 'no splitters'. I don't know how accurate they
I haven't bothered with it, Doug. I see it mostly as an "exercise in futility". The "cops" never ID, and the MOST TROUBLESOME QRM is from "packet-rats" seeing the spots and then tuning up interminabl
I am waiting for the reverse DQRM project; the one that will deal guys who are deliberately QRM'ing MY signal when I am trying to call the DX station ! They know that is my frequency to use and they
It would be nice to set something like this up that works, but it would take more than just how loud someone is. Strength alone is pretty much useless. _________________ Topband Reflector Archives -
Strength is useless unless he is a local. We have been dealing with one for years, but he preferred to harass SSB ops on 20. The FCC issued a $22,000 NAL last year. Maybe that will shut him up. _____
I think the fact that something positive is being done is working, even if it is electrically futile it is definately putting some DQRM'ers off, the DQRM has been noticeably less and with K1N ops and
IIRC, quite some years ago, QST had a photo & description of a FCC "signal locator" (for lack of a better description) consisting of several remote receivers that were linked together. Anyway, these
A poster on the cluster said it the best: DQRM triangulation = nonsense idea! There is no way this is going to identify the offending station(s). IMO at best a bluff. Doug --Original Message-- Is any
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, e
Amen! 73, Charlie, K4OTV A poster on the cluster said it the best: DQRM triangulation = nonsense idea! There is no way this is going to identify the offending station(s). IMO at best a bluff. Doug --
A couple of observations; The DQRM with EP6T was by far the worst I have ever heard. My guess is a lot of it was because of angry people who did not like Iran as the DX location. If that is correct,
I didn't see the ARRL article, but I have researched this on the Web. Type these words into Google: fcc hf df The first hit is a map of where they all are. Most are unmanned. They are all linked to a
If anyone wants to look at the antennas, the exact addresses of all the FCC HF DF sites are in this document: transition.fcc.gov/omd/contracts/pre-award/RFQ11000024.pdf Type the address, city, and st

IMHO, the K1N 'DQRM Tracking Project' is fostering perpetrators to flex their muscle and mettle and challenge the status quo. The K1N web site proclamation " the objective is to identify stations w
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

Greetings top-band community, Interestingly enough the technology exists right here in our own Ham community that could go a long way toward finding these DQRM culprits. There are some beam forming a
Are you sure that will work with sky wave signals? 73 Peter Being able to actually replay an entire contest and do a strength and directional analysis in a narrow bandwidth after the fact to me is th
I agree, Lee. Locating a DQRM station involves accurately time stamping the arrival time of their transmissions, at (at least) three receivers at known locations. Once the arrival times are known, on
No of course not Peter, I think it would work fairly well on one hop and ground wave signals judging from my experience with narrow beam arrays. As much skewing as we see on distant signals and the f
