Many customers have the need to extend the communication distance of walkie-talkies. At this time, repeaters are needed. Our most popular product is the RT97 repeater,it is divided into GMRS version and customized frequency version which need to customize the repeater frequency.
The RT97 repeater can be used not only on farms, but also in outdoor activities such as hiking, exploring, and mountaineering.and it is small and lightweight, which is very easy to carry.
Some customers’ walkie-talkie frequency is GMRS, so they will choose GMRS repeaters.
Some customers have their own frequency bands, so they need to customize the frequency they need.
However, many customers do not know how to customize the repeater frequency.
This article will explain what is needed to customize the repeater frequency.
1.Confirm the center frequency.
Before customize the repeater frequency, you need to confirm the center frequency, that is, Tx: AAA.AAAMHZ RX: BBB.BBBMHZ. If you don’t understand this, you can set the center frequency to the frequency you often use.
2.Center frequency requirements when customize the frequency.
(1) The customization range of TX: AAA.AAAMHZ and RX: BBB.BBBMHZ is 136.000-174.000MHZ / 400.000-470.000MHZ
(2) AAA.AAAMHZ minus BBB.BBBMHZ, that is, the frequency difference range is between ±5MHZ and ±12MHZ.
3.Frequency writing requirements.
If the center frequency is regarded as the first channel. For example, if the center frequency is Tx: 142.000MHZ RX: 147.000MHZ, then the frequency range of channels 2-16 is Tx: 142.000MHZ+-200khz RX: 147.000MHZ+-200khz.
4.Match the frequency of the walkie-talkie.
When we use the repeater, we must consider the frequency range of the walkie-talkie. If you want to promise radio call,Please keep the frequency of the walkie-talkie and repeater the same,of course CTCSS /DCS should also be consistent.
Through this article, I believe everyone has a certain understanding of ustomize the repeater frequency. If you have any questions about ustomize the repeater frequency, you can contact us at any time.
