New Radio IF 9MHz Description

New Radio IF 9MHz Description

In the period 2004-2005 we constructed our new transceiver where its frequency synthesizer is based on DDS AD9832 from AnalogDevices, and a PIC16F877 processor from Microchip for controlling.

Demonstration

Here we demonstrate the sound quality achieved with the new transceiver.

New Radio Demonstration

Description

This new project turned out to be much more successful than our old transceiver. The final result was a SSB/CW radio with 1Hz step, which was able to work with two frequencies, remember up to 40 channels, and was able to calibrate a DDS for each diapason. The synthesizer produces very low noise and has good speed.
