An improved apparatus and method for selecting a carrier frequency channel between two radios are disclosed wherein one radio transmits a cyclic test signal sequentially on a set of frequencies for a period of time at each frequency sufficient to allow a second radio of sweep through the entire set while pausing at each frequency for a period of time sufficient to receive a cycle of the test signal. The second radio utilizes the detected test signal to evaluate the transmission quality of the carrier frequency channel upon which it is received. After the second radio recognizes the test signal on a carrier frequency for a second time, it ceases evaluation and transmits an answer signal upon the carrier frequency with the highest transmission quality. The first radio is enabled to detect the answer signal by initiating reception at the end of each test signal transmission and sweeping through the entire set of frequencies at the rate of sweep on the second radio.
