In my quest to dump the Arduino MCU, I consulted the Oracle at YouTube. A short tour through the videos turned up a project to create a digital LO using the Pi Pico and a Si5351.
It was not from the Kingdom of HamSpeak but the CB world. This is a great example as it could also be the basis for creating opportunities using the SSB CB Transceiver architecture for use on the ham bands.
This is seed information to start a transition away from the Arduino. It is a twofer as it also is a starter project to get a cheap CB radio to work the 10M band.
As seen on hackaday a two element VFO using a Crowpanel Circular Display (with internal esp32 MCU and encoder) and a Si5351. That is the whole shebang. Hook up a couple of wires and you are there. This is like the JF3HZB circular display in a really compact assembly. Total cost with the Si5351 is about $35 and available at Bozos (Amazon).
So, who needs the Arduino and Qualcomm. Caveat Emptor as you would have to know stuff to use the RPi Pico and if you are starting from ground zero... not for the "newbie". Be it known that would apply for the Arduino as well. One mod is that the CB project is for channelized tuning and so the code would have to be modified to use an encoder.
Them that know can make things go.
In the last 30 Days the highest viewed blog posting is still BB on the beach with her top off. Well, we definitively now know that contests and operating are not the only things on a hams mind!
