First off I do not recommend using a repeater for tactical use . If you have been following my writings you know I am all about lowering your RF signature. Using a repeater expands your RF signature and is a big NO NO in the tactical realm.
Now having said that there could be some situations where you need to setup your own repeater and thats what I’m going to discuss today. Some examples could possibly be Search & Rescue, hunting party, or even out camping. First off what is a repeater?
From Wikipedia: In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.
We will be dealing with a cross band repeater.
From Wikipedia: Crossband (cross-band, cross band) operation is a method of telecommunication in which a radio station receives signals on one frequency and simultaneously transmits on another for the purpose of full duplex communication or signal relay.
The radio we will be using is the TYT UV8000E. It is a 10 watt dual band radio that have a cross band repeater feature which makes it a great addition to your comms plan.
On this radio we are mainly concerned about 2 menu options. First is menu 6 and then menu 11. Menu 6 gives you both frequencies on top and bottom of the screen at the same time. You want menu 6 selected to “ON”
Next is menu 11. Menu 11 says TURN. You want that selected to “ON” also. With those 2 options selected on MY radio the cross band repeater is working. Then all you need to do is have your radios programmed to the TX/RX frequency that is punched into the TYT radio.
Using the picture below we will say our TYT UV8000E Repeater on the mountain has the frequencies of 151.820 on the top line and 462.5625 on the bottom line. The car to the left of this picture would have 151.820 programmed into thier radio and the car on the right side would have 462.5625 programmed into theirs. All they have to do then is talk as normal and the repeater will relay from their frequency to the other frequency and vice versa.
This is a pretty simple repeater setup that would be a great addition to your comms kit.
