PCT No. PCT/FI96/00684 Sec. 371 Date Nov. 19, 1997 Sec. 102(e) Date Nov. 19, 1997 PCT Filed Dec. 20, 1996 PCT Pub. No. WO97/24817 PCT Pub. Date Jul. 10, 1997A method and an equipment for controlling a multi-branch frequency-hopping receiver equipment used in a radio station, especially in a base station of a cellular radio system onto a desired frequency when a band-pass filter (BPF2) responsive to an external control signal (VBPF) has been arranged for each branch of the receiver equipment, the control signal (VBPF) of the band-pass filter being controlled in sync with frequency hopping. The control signals (VBPF) of the band-pass filter (BPF2) are determined for each frequency (C) and each filter (BPF2) and this information is stored in a tuning voltage memory (TVM) from which it is retrieved in sync with frequency hopping.
