From the project
The microPython module to control the SI5351, si5351.py, was provided by https://github.com/thaaraak/Tinypico-Radio/tree/master. Some minor changes were made to the setter in order to allow individual clock enabling/disabling--used for the AM mixer local oscillator.

The radio control is handled by radio.py which after initializing a , can be used to parse Quisk commands and automatically control bandpass filter selection (based on frequency) and frequency. The bandpass filters can also be controlled manually by entering "BAND,AUTO" to allow for manual testing and use of the built in bypass…
