Setting up 2 Radios as a Repeater

There is a good chance that you have already watched at least one of the following Youtube  videos.

Both show how to make a repeater by linking two radios (usually Baofengs). But I am having my reservations about the wiring they use.

This one has it DEFINETELY wrong.Set up a Baofeng UV-5R Repeater System

Similarly,  Miklor’s site shows the same method in detail.

The reason is explained in the second video, but still I cannot get what he is doing with the wiring.

HAM repeater (field expedient) using UV-5R Radios

So let’s take it from the start.
Below is the Kenwood type interface, applicable to most Chinese radios our there (Baofeng and Wouxons for sure).

My Tupperware Baofeng Radio Kit

First I am cheap. Then I am unemployed. And lastly it is foolish to travel to the next big city to find a padded pelican case and pay for it as much as the kit costs, AND as much for gas money. So an old Tupperware brand food container was used. See, I do try for quality when I can!

And those being so popular and cheap are two of the reasons for trashing them around the web. But are they…

 

Glorified FRS radios or Incentives for new HAMs?

 

Among the preparedness and survivalist communities the BAOs are prevalent. And I do not think there is anyone that has a second radio and it is not a UV-5R. so even the advanced HAMs among us could not resist the temptation of the cheap and “easy” radio.

New Batterypack and Custom UV-5R Battery Eliminator

This is a continuation of two other projects the External Battery Pack for our handheld radios and an improvement on the Battery Eliminator we did for the Bao.

The Battery-Pack / Powerbank

This is a smaller size using two 18650 Lithium-ion rechargables to get the same voltage as the original Baofeng battery.

We have an affinity for the 18650 batteries, mainly because they are easy to handle, they lead the battery technology at the moment, can be cross loaded to other devices such as USB powerbanks, and we have a plenty of, since we are into flashlights too.
