I would like to use Arduino nano for my homemade HF rtx, I do not have many programming needs:
generate a frequency from 1 to 39 mHz controllable by encoder with steps of 1 - 5 - 50 - 1000 - 10.000 - 100.000 - 1.000.000.000 Hz as the OL and to be displayed on a display 2 lines 16 characters.
generate a fixed frequency of 9,000,000 mHz for the IF
Having a frequency reading offset, in my case the beat is always F + IF for which an F-IF offset is needed.
to be able to give a fast analogue command in external voltage to move the OL less than 500 Hz in CW reception (I’m not interested in changing the display reading of 500 Hz)
I do not know anything about Arduino so I would need a software already made that approaches my needs, then learn to modify it for my use if it does not already have the required requirements.
I was thinking of buying, in addition to Arduino nano,
an AD9850 to generate the two separate signals:
a display compatible with Arduino:
a full interface encoder:
I kindly ask you to help me in the enterprise if possible, I’m really fasting on the subject, thanks !!!
