Abstract :
The replacement of a tropical band broadcast system for the nation of Vanuatu with antennas designed for frequency changes responding to propagation changes has introduced new challenges in managing the service. Operational experience has highlighted some aspects needing regular maintenance, but much of the equipment has been trouble free. Practical limitations in using the system are discussed
