Amateur Radio Position Updates

When you upload an amateur radio logbook, in ADIF or Cabrillo format, the 'Time Mapper UHD' program needs to know the position of a callsign before it can show it on the map. Sometimes, in the case of ADIF logs, the positions are included in the QSO entry, but at other times there are no positions available, so the program has to provide one. It does this in a number of different ways: online georeferencing from HamQTH.Com, or by querying a pre-referenced SuperCheckPartial table, which includes many of the regular contesters. The random-position routines work very well for many countries, as they use the callsign to determine the region of a country where the call is located. For the USA, Canada, and Australia we can take advantage of online callbook information that is made available by the relevant licensing authorities. The program maintains georeferenced tables based on zipcode or postal code. Whilst not completely accurate, it is perfectly adequate for a world map of this scale. Try grabbing a log off the CQWW Public Log download page (https://www.cqww.com/publiclogs/) and see what it looks like on the map.

 

The program ships with pre-downloaded databases for the USA, Canada, and Australia, but after some time you will wish to update them with the latest data. To do that, click the relevant button on this page. A new window will open: you will first download the latest dataset, then unzip it, and then process it. Please note that there is a lot of processing that goes on behind the scenes, and you can expect the routines to take 10 or 15 minutes, during which time you can't use the 'Time Mapper UHD' program in its normal mode.
