Design of the diplexer
The diplexer contains additional filters for 261 kHz, 531 kHz, and 1575 kHz. These are frequencies which are also radiated from the antenna site in Burg.
Presently the frequency 261 kHz is not on air.
Radio Europe intends to use this frequency on the ARRT antenna for drm transmission with 40 kW which corresponds to 100 kW AM power.
