Aim of the project

This zone is centred on Paris area. Therefore, a beacon located near Paris is very useful in restoring a good homogeneity in 144MHz beacon coverage. This is the primary justification of F1ZXK beacon. Furthermore, this beacon is also located in an area of dense radioamateur population in France. It means that if you can hear F1ZXK, you have a good opportunity to work many French stations living in this area (JN08,JN18,JN09 and JN19 square).

 

Spot the beacons

Please, don't hesitate to spot the VHF beacons. It is really useful because:

- it gives important information about the propagation conditions. It is useful for radioamateurs and also for propagation studies

- it constitutes an important feedback for beacon owners and coordinators

Therefore, do not hesitate to spot beacons (even in case of standard propagation). Please, spot F1ZXK and all the other beacons.
