SDR-1000 Description
During 2008-2009 we constructеd our own version of SDR-1000 transceiver based on information in internet, it uses DDS AD9854 from Analog Devices. Gallery Description This project was very successful and the sound quality of the receive/transmit is incredible. This is a software radio, so to be able to function correctly you will need a PC… Continue Reading
New Radio IF 9MHz Commands
Here are pictures of LCD panel in different modes of transceiver with commands description. The functions that we support are easy switching between the main frequencies, tuning of generators, setup of memory channels. Base Functions Shows RX/TX receive or transmit, base frequency, LSB/USB/CW and step (1Hz, 10Hz, 50Hz, 100Hz, 1kHz, 10kHz, 100KHz) Mode for tune,… Continue Reading

Here you will find schematics for our homemade new SSB/CW transceiver. Synthesizer is based on DDS AD9832 from AnalogDevices and controlled with microcontroller PIC16F877 from Microchip. Schematics Continue Reading
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 Galery Description This new project turned out to be much more successful than our old transceiver. The final result was a SSB/CW radio with… Continue Reading
Old Radio Description
In 2000-2001 we constructed our first transceiver with a frequency synthesizer that is controlled by PIC16F84/88 microprocessor from Microchip. The VCO is based on integral schemes HEF4750V and HEF4751V from Philips. Gallery Description Originally we used a microcontroller to control a VCO synthesizer. There were a lot of challenges with writing the program and testing the… Continue Reading
