The present invention relates to a method for tuning a radio filter. The filter comprises an input connection, an output connection and at least two resonator modules coupled in cascade, each having a tuning mechanism and a probe. A first resonator module is connected to the input connection and a final resonator module is connected to the output connection. The filter is adapted to receive at least one signal within a frequency range. The method comprises essentially two steps: coarse tuning, which is dependent on the frequency content of the received signal(s), and fine tuning, which is dependent on a calculated deviation between a set value vector and a measured signal parameter vector. A relationship between the set value vector and the signal parameter vector is established for calculating the deviation. The invention also relates to a radio filter and a system comprising such a radio filter.
