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.

Sound Quality Sample



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.
