Thus a spare rig may be loaned out to different operators, but only one operator per month. Cooperation and amateur spirit are encouraged. This ain t a DX contest. Any mode that allows exchange of information is permitted, within rules of FCC or other licensing authority. Each contact scores one distance point for each kilometer distance between the 6-digit grid squares, as calculated by the BD program.
EME contacts use terrestrial distance if grid squares are exchanged, as above.
If only TMO reports are exchanged, then the contact is scored as 500 distance points. All colors of light count as one band. If a station changes callsign during the year, each may be counted. Any contact made on a band where the operator has never ever made a contact before scores an additional 1000 bonus points. This means once in a lifetime for each band.
