Hello Everyone.
More development on the DDS and we would like to bring you a new feature in the DDS.
Ever had a passing thought that while changing frequencies during some experiments or while scanning the Rx. for stations, you would have always wondered - 'It would be great if there was a shortcut to jump to this frequency'. While that feature is termed or coined to be as Preset.
Voila, we now have a DDS with Preset feature. We have added three Preset frequency, which are set to 4.97MHz, 4.95Mhz and 4.93Mhz. Well, of course, the frequencies can be changed in the program.
Below is the modified circuit of the DDS to accommodate the Preset frequency switches:

The DDS with Preset function was just a prototype and the PCB does not exist yet. Depending on the demand, the PCB's will be made.Also as usual, suggestions and comments are most welcomed and noted.
Stay tuned for another exciting feature to be added to DDS pretty soon!!!!
