PURPOSE: To reduce the equipment cost accompanying writing operation by improving the efficiency of operation for writing channel data such as data, modulated signal data, and transmission output data in plural radio transmitter receivers used by a group.
CONSTITUTION: A control part 2 of the radio transmitter receiver consisting of a radio part 1, the control part 2, and an input/output part 3 is provided with a memory 7 stored with a transfer program which reads the channel data on its transmitter receiver out of a data memory 6 and transfers and copies the data to other transmitter receivers of the same kind, and the transfer is carried out by easy key operation at an operation part 4. Consequently, the channel data are only written in one starting transmitter receiver at a sale source and can easily be transferred directly to other transmitter receivers at stores.
