| 摘要 |
<p>The invention relates to a radio device for operation in at least two different radio systems having unequal bands of operating frequencies represented by channels numbers. The device comprises a radio trasmitter (1); a radio receiver (2); a frequency synthesizer (3) for generating local oscillator frequencies for the radio transmitter and radio receiver; respectively and a control means (4, 5) for controlling the frequency synthesizer (3) so as to look it to transmitting and receiving frequencies corresponding to a selected channel number. In the invention, the control means comprises a memory (5) for storing frequency synthesizer control data of a single channel number for each different radio system, on the basis of which control data the control means is capable of deriving control data of any other channel number for the radio system in which the radio device is currently operating.</p> |
