K head relay walkie talkie k head two way radio repeater box does not need power supply. There is no need to change any part of the original walkie-talkie, just take two handheld walkie talkies. Use two handheld walkie talkie headset jacks to form a very practical small repeater through this relay box.Radio repeater box is made of ABS. Plug: K head. Color: black. Whether it is two-way: yes. Line length: both sides are 90cm/35.4in long (Left and right). Distance: 5-8 km from open space, 1-2 km from densely populated buildings. Radio repeater box is portable and easy to use.Two-way relay box plug does not divide input or output, two-way relay box forwarding mode: A machine receives B transmission, B machine receives A transmission.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.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. Working Mode: 1. 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. NOTE: 1. This relay box is an audio trigger mode, so please adjust the volume of your walkie-talkie to the maximum when using it, otherwise there may be no forwarding status. 2. If the transmission delay time is too long (more than 3 seconds), the transmitter's transmitting antenna is too close to the relay box to cause the transmission signal to interfere with the relay box! The external walkie-talkie antenna can be used to solve the interference problem!
