The DV-RPTR board is a DV Modem based on a powerful 32 Bit AVR microcontroller. All DV functions are implemented in software.

The DV data from an FM transceiver is fed into the ADC input and then processed with a couple of digital signal processing routines.
The connection to the PC is done via an USB interface. A driver is available for Windows (XP, Vista, Win7 or even the upcoming Windows-8). Under Linux the board is detected automatically and no driver is needed (tested with Ubuntu and Cent-OS).

* An integrated DFU 1.1 compatible bootloader allows firmware updates for the end user.

* A couple of PC software packages support all functions required for DV operation.

* This board is made for HAM operators for use as hotspot, or for DV repeaters in various operating modes.

* A special website was build for this board: http://www.dvrptr.de/

* This board and its corresponding software is open source and available for everybody.
