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:

Exact latitude and longitude where known
Locator sub-square center if given
Approximate latitude and longitude from geographical location.
Distance as claimed by the QSO participants.
Corner of locator square nearest to QSO partner

Calculated distances may change if better information on station location becomes available.

If you have any information on a possible record or exceptionally long distance QSO please send it to the IARU Region 1 VHF/UHF/Microwave DX record co-ordinator:
