Paul D. Lieb, KH6HME (sk), began operating a group of beacons starting in April, 1979. The first was the 432.078 MHz beacon followed by the 1296.250 MHz in 1980 and the 144.170 MHz in 1981. There are also 220.100 MHz and 50.061 beacons that operate intermittently.
When the beacons were being heard on the mainland, Paul would drive to the site to allow stations to work KH6 land on the three bands. Located on the slopes of the Mauna Loa volcano on the Big Island of Hawaii at a 8200 feet the trip to the beacon site would take three hours.
The beacons are located at BK29go. Here are sound files as received at my QTH on the Pacific coast in southern California at DM03ts. The distance is 2472 miles.

The beacons are now being maintained by Fred, KH7Y, a long time friend of Paul. Thanks, Fred.
