You get a 144/220/450 MHz, 200Mw, FM transceiver board that is compatible with an Arduino shield connection. It can also take a 12VDC input and provide 5V power to your Arduino board and charge a Lithium Ion battery. To add to the features, It has CTCSS detection and generation; can provide an output to the Arduino with board temperature or operating voltage; can provide a timed, CW ID; can produce and detect DTMF tones; functions as a beacon transmitter.
I currently have two projects under development:
- A controller for a Kenwood TMV71A transceiver operating in Crossband mode as a remote simple base. I can use DTMF tones to change the operating frequency. This also works with a Kenwood TS2000. I am using an Arduino MEGA for it's hardware serial ports enabling me to control the RSUV3 at 19200 baud. I have four pushbuttons and a serial, 16x2 LCD display for the user interface. Completion of the project is waiting for the 10W tri-band power amplifier scheduled to be shipped in November.
- A simple remote power controller for a repeater. I am using the RSUV3 to detect DTMF tones of a command string and send the results to an Arduino PRO MICRO. When a valid on/off command is received, the Arduino operates a solid state relay to control power to the repeater accordingly.
