the beacon network to include 18110, 21150, 24930, and 28200 kHz.

(WWVH) to hear the propagation forecasts.

When operation begins on these new frequencies, avoid transmitting

on them as well.

NCDXF/IARU BEACON NETWORK

The Northern California DX Foundation and the International Amateur Radio Union are cooperating to support this particularly useful on-the-air tool. The network is monitored by scientists, students, etc. as well as Amateur operators.

This group of stations are located in North America, the Pacific, eastern Asia, the Middle East, Europe, southern Africa and South America, and more stations continue to be added to the network. They transmit beacon signals on 14100 kHz consecutively in sequence at power levels from 100 watts down to 100 milliwatts. You can listen to each station transmit with a known power from a known direction and location.

With minimal effort, in a brief time you can compile a customized and accurate profile of HF propagation conditions at your location. This information will help you decide where to point your antenna to look for DX or to call CQ. You could even distribute the information via packetcluster to local friends for their benefit. Or, because of the very precise timing used for each transmission, possibly you could develop an automatic means of monitoring the beacon frequencies, then assemble the recorded signal levels into a meaningful database for later consultation.

HF BEACONS

Beacon stations transmit from locations in many countries. Often they operate 24 hours per day and, if you can hear a particular beacon, you know there is some propagation to that area of the world. Consult reference books such as the ARRL Repeater Directory for detailed information on active beacons. The table below lists some beacons that you may hear.
