The four fields with a red caption are required. You cannot make a logbook without them.
| Field | What to fill in |
|---|---|
| Callsign ● | Your call. It goes into every QSO, onto your QSL labels and into the Cabrillo (contest log) file. |
| Operator ● | Who is operating. At home that is your own call. At a club station or field day it can be someone else - see below. |
| Locator ● | Your Maidenhead grid locator (grid square). Typos are caught. Do not know it? Use Find Your QRA Locator. |
| QSO Location ● | Where you are, in words - your town or site. It goes into your ADIF exports and can be printed on a label. |
The distance and heading to every station you work are worked out from this locator, so get it right.
