How to homologate a record?

French version

HB9AFO has taken the task to register all records in relation with amateur television, and this at a world level. His information sources are coming from the owner of records themselves, that send him reports of their QSO, and also in reading specialized ham magazines. In each case, he try to obtain a maximum of useful informations directly from owners of the record QSO. The following panel gives the actual state of ATV world and european records. To able to compare, the narrow band (SSB/CW) world records are given for each band.
