Notes

The abbreviations used in the propagation mode column are:
Tropo Tropospheric
Aurora Auroral
Spor-E Sporadic E
Meteor Meteor scatter
EME Earth-Moon-Earth (Moonbounce)
F2 F2 propagation
TEP Trans-Equatorial Propagation
Au-Es Auroral sporadic E
Iono Ionospheric scatter
FAI Field Aligned Irregularities
Rainsc Rain scatter

The distances were calculated using the International Ellipsoid of 1924 (polar radius 6356.912 km, equatorial radius 6378.388 km).

A description of the method used to calculate distances, with C source code, is available for download as a Word 6 file (225k).

Propagation modes are those reported by the stations concerned. However, it can sometimes be very difficult to distinguish between propagation modes. This is especially so on 50 MHz, where mixed-mode QSOs are common, and to a lesser extent it applies on 144 MHz. The propagation information should be read with this in mind.

Station positions were taken from the best available information, in the following order of preference:

  1. Exact latitude and longitude where known
