First of all it is necessary to create logbooks set. It is a basis of all subsequent operations, only after import of QSO to thelogbook it is possible to apply other useful functions of system. The inexperienced user will create only one logbook, and stop on it. It is not the best approach, however.
CheckLog system gives flexible opportunities on selection of the necessary QSO both for formation of the list of the proceeding QSL, and for the statistical analysis of results. And you should use these opportunities. What will be if to create one logbook for one callsign? You lose at once opportunity to operate selection of QSO in other data presentations. The list of the proceeding QSL can be created taking into account the operator who was carrying out communications (the full callsign, with all keys is specified here). It is also structured according to separate logbooks (it is possible to watch selections according to all logbooks, or on some defined). Therefore we begin a configuration of structure of logbooks with definition of those options which will allow to build further selections of data taking into account all set options.
For example: I work from a city location (R2ADF), from the village (R2ADF/A), I can use the low power of transmitting signals (QRP) for carrying out QSO. And, besides, from year to year conditions of carrying out communications can change (I constructed the new antenna, I put some new equipment, etc.). Therefore the structure of logbooks should be set so that all these features were considered, on the future.
