Current beacon reports on the Reverse Beacon Network



Dai Nagakura, JF2IWL, shows the most recent beacon reports on the RBN using DX Atlas on his web page.

What Beacons are Being Heard?

There are three ways to determine which beacons are being heard in various parts of the world. You can check for reception reports (spots) made manually by amateurs who have heard the beacons and have posted a spot on a local DX Cluster or directly to DX Summit. Or, you can check with web pages showing automated reception reports of the beacons by Faros software or the Reverse Beacon Network.

IBP-RBN Challenge!

Can you hear all the beacons from your location?

Can you hear them all in one day?

On August 20, 2017 at 1941 UTC, the CS3B beacon from Madeira began transmitting with the new version 2 beacon hardware. For the first time ever, all 18 beacons in the International Beacon Project are operating at the same time on all 5 bands.

The opportunity to hear all 18 beacons in one day has never occurred before. Now is your chance. Before lightning strikes a beacon station, or a hurricane knocks down an antenna, or a component fails, or the rig is stolen, as has happened before every time we were close to 100%. Many of the beacons are in remote locations on mountain tops or subject to the corrosion of salt air by the sea shore. We try to keep them all on the air, but you can never tell when one will go down for some time.

On August 27, OH6BG's skimmer picked up VK6RBP and JA2IGY making him the first RBN-op to report all 18 beacons. Over the 3 day period from August 25 to 27 he heard them all. Congratulations!

Jari tells me that they run a QS1R, a 10dB preamp and a TH7DXX at 40m ASL (by the sea) plus a multiband vertical in an extremely quiet QTH on an island south of Vaasa. They turned the antenna on Sunday to pick up the missing beacons. Jari's propagation tools probably helped.

On November 7, 2017, with few hours of daylight in Finland and despite an active G2 level geomagnetic storm spreading a broad aurora, OH6BG managed to hear all 18 beacons in one UTC day. Solar flux was 68, the estimated A-index was 36 and K was 6. These were not the conditions in which we would expect this to happen.

On April 26, 2018, WZ7I unblocked spots of 4U1UN, and became the second spotter to have reported all 18 beacons. Locals had requested he not spot 4U1UN.

On April 27, 2018, DJ9IE joined the elite club of spotters to report all 18 beacons.

On June 10, 2018, GW8IZR joined the elite club of spotters to report all 18 beacons.

On May 9, 2019, ON5KQ reported hearing KH6RS to reach the 18 beacon total.

On May 13, 2019, CT1BOH reported hearing KH6RS to reach the 18 beacon total.

The Reverse Beacon Network involves hundreds of volunteer monitoring stations using CW Skimmer to monitor for CW callsigns and report them via the RBN web site. If you operate a skimmer, please adjust the settings and add the beacons to Watch.lst to optimize reception of IBP Beacons.

The Reverse Beacon Network can be used to show reception reports of the beacons by users who have added the beacon callsigns to their watch list. N4ZR explains how to do that in his NCDXF Beacon Spotting Redux blog post. If you have not changed the KH6 beacon to KH6RS in your Watch.lst file, and downloaded the latest version of Aggregator, please do so now.
