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.
Shows RX/TX receive or transmit, base frequency, LSB/USB/CW and step (1Hz, 10Hz, 50Hz, 100Hz, 1kHz, 10kHz, 100KHz)
Mode for tune, from -99 999Hz to +99 999Hz
Mode for direct entering of frequency from keyboard.
Mode for save current frequency in one of the 40 channels memory. Also it saves state of the buttons on front panel. (ATT, AMP,+10db and VOX)
Mode for load frequency and settings from one of the 40 channels in memory.
Mode for changing diapason.
Mode for working on two frequency A/B. A is used for receive and B is used for transmit.
Mode to change B to be for receive and A to be for transmit.
You can enter direct frequency for one of A/B directly from the keyboard.
Settings and Calibrating
Mode for set diapason of the 5 base generators which cover all 0.5-30MHz diapason.
Mode for calibrating DDS. It can be calibrated separately for each diapason to achieve very accurate showing of working frequency on the LCD.
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
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
