Hello everyone.
We are working on the DDS and have updated the new program for the fine tuning (Slow bit tuning). The program is written for the PIC16F628A with the following features:
We have incorporated the DDS board to out JOTA TRx. 40 and have tested it on the air. Smooth transitions between the frequency and on-spot frequency setting.
Dr. Manoj, VU3KER will the first one to take our TRx. equipped with DDS for testing and feedback.

We are working on the DDS and have updated the new program for the fine tuning (Slow bit tuning). The program is written for the PIC16F628A with the following features:
- The slow/fine tuning is adjusted to 54 Hz frequency up and down.
- The range of the slow/fine tuning is no more limited and can be adjusted to any range of frequency.
- The delay between the frequency switching is reduced to 0.5sec. Hence faster band scan.
