HOBBYPCB RSUV3 Tri-band Transceiver Board
« on: September 23, 2015, 10:33:04 AM »

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.

How difficult is it to get the Arduino to operate as a serial port? What language do you program the Arduino in?

Depending on the board you are using, an UNO has hardware serial RX/TX ports that are used for communication from the host computer to the board via a USB interface.  To get additional serial ports (TTL compatible) you use a library call SoftSerial that creates additional ports using GPIO pins.  The ports are limited to a maximum 9600 baud data rate.  An Arduino MEGA has addtional hardware ports that can run at high baud rates.  Various other Arduino boards are more or less capable.
