The DQRM Tracking Project

Recently, the amount and intensity of DQRM (Deliberate QRM) has been growing logarithmically, targeting DXpeditions all over the world.  DQRMers attempt to spoil communications and disrupt the joy of chasing DX -- both for those who need to contact the entity, and for the teams who, at considerable expense, activate stations to share contacts with fellow hams worldwide.

Without going into the motivation of DQRMers, the DX Community is taking steps to eliminate this practice.

The KP1-5 Project, which is producing the 2015 K1N Navassa DXpedition, has been working with tele-communications agencies around the world.  The objective is to identify stations who are acting as DQRMers and use legal means to stop this behavior.  The technogy is in hand to solve this problem and, with your assistance, we can stop this blight that is hurting hams worldwide.

How it Works

Locating the stations engaging in DQRM is a matter of triangulation. When the DQRMer is 60db over S9 at your location, you can be pretty sure that station is nearby. If you fill out the form below, our software will collect and analyze the data to produce a reasonably accurate map of the DQRMer's location. This data will allow a close-in search in the DQRMer's area and, using local transmitter hunting devices, the offender will be identified.

This is a real-time system that's been in development for several years; its first major test was the 2015 K1N Navassa DXpedition.

The K1N DQRM Project has ended

We received more than 1,000 DQRM reports and the data is now in an international database for processing.  If you participated, thank you!
