Foreword

This is my DSP-10 transceiver project - a Software Defined Radio (SDR). The project is build of three parts. The EZ-KIT Lite ADSP-2100 based Digital Signal Processor from Analog Device, a simple audio amplifier board and the DSP-10 board. The EZ-KIT Lite is a ready build DSP board that "just" needs some DSP firmware. The DSP-10 RF board is based on a construction from W7PUA.

Functions

The DSP-10 transceiver is working as a Software Based Radio (SBR) and is controlled by a peice of software by on a personal computer.

How to connect

Connect a personal computer to the RS-232 connector at the rear, an antenna for 144-146 MHz to the antenna connector at te rear, a speaker to the speaker jack at the rear, a microphone to the microphone connector at the front and 12V of power. Start the DSP-10 software on the connected computer and you are you are simply running the DSP-10 transceiver.
