Harmful Interference by Meteo Beacon of French Ultra Light Planes

Harmful Interference by Meteo Beacon of French Ultra Light Planes on Swiss 2-m-Repeater

On 14 July 2008 the Swiss radio amateur HB9DTX, OP Yves Oesch, reported harmful interference to the Swiss (USKA) Intruder Watch. Swiss amateurs soon found out, that a group of French pilots of Ultra Light Planes had installed a meteorological beacon on the exclusive amateur radio frequency 145,000 MHz: Every 15 minutes there was a bulletin with meteorological data concerning the region of Agy Plane. Agy Plane is situated 20 km south of the Swiss city Geneva on French territory in Haute Savoy Department. These transmissions were causing harmful interference to the Swiss repeater HB9MM (location “Les Pléiades” near Vevey) whose input frequency is 145,000 MHz.

A direct letter to the Secretary of the Ultra Light Club “Agy Plane”, to OFCOM and to the Swiss coordinator of USKA Intruder Watch HB9CET by HB9TOB, OM Olivier Maillard soon led to a free frequency 145,000 MHz.

“We have fixed the problem of the beacon and have returned to the correct frequency. With all our excuses for the trouble yours, Pierre Bourier, Secretary of “Agy Plane”.
