Dualband radio hotspot

With the DVMEGA Dual Band Radio and ARDUINO board basis you quickly make a 10 mW hotspot for D-Star or DMR which operates on VHF or UHF.

The dual band radio is later used in the transceiver kit.
- Fits on Arduino UNO and MEGA 1280/2560
- Dualband VHF/UHF radio
- 10 mW output power
- SMA antenna connector
- Complete assembled
- D-Star and DMR

Step 1, Install USB driver for Arduino.

It is recommended to use for loading the firmware a standard Windows PC.
First you have to load the USB driver for the Arduino. Normally it will be recognized by Windows, in cases where it is not, I recommend to visit the following links:

Arduino website : http://arduino.cc/en/guide/windows
Youtube : http://www.youtube.com/watch?v=-epgmDX9Zfw
Step 2, Load the firmware.

Download and install Xloader. This is a simple program to load the firmware.

Download the hex file for your ARDUINO :

Start Xloader, choose the correct hex file, select Device and set the COM port to the port number that is assigned to the ARDUINO. The baud rate defaults to 115200. Then press Upload to load the firmware. If the firmware is loaded correctly a message will appear below in the bar of the Xloader screen.
Step 3

Installation G4KLX D-Star repeater.
