Different frequency uplink and downlink difference forwarding (and conventional relay station), A machine as the signal uplink receiver, and B machine as the signal downlink transmitter. The relay has been achieved. 2. Two-way forwarding, when the A machine receiver, the B machine transmits. When the B machine receives, the A machine launches. The two-way forwarding function is achieved. 3. This relay box is an audio trigger mode. When using it, the volume of the intercom as a receiving signal should be adjusted to the maximum! Single/two-way relay box frequency setting prompt. 4. One-way relay box forwarding mode (regular repeater mode)! The A machine receives the signal and the B machine transmits the signal. The receiving/transmitting machine must be set to two different frequencies. The frequency set by the conventional transmitter is higher than the receiver frequency, and the high/low frequency is low. The high/low frequency difference is generally 10M, and the larger the frequency difference, the better. 5. Do not reverse the jack of the one-way relay box during use, otherwise the relay box will not work. 6. Two-way relay box plug does not divide input/output, two-way relay box forwarding mode: A machine receives B transmission, B machine receives A transmission. Review: This thing works great. DO NOT turn on VOX. Works best if antennas are separated several feet. Review: bought it because but I have never used it ## Features - 【Plug and Play】No power supply needed.
