Please, follow the circuit available on that link.
If you are using a SI4735-D60 or SI4732-A10, you can also use this sketch to add the SSB functionalities. If you are using the SI4730-D60, the SSB will not work. But you will still have the SW functionalities.
Be sure you are using the SI4735 Arduino Library written by PU2CLR to run this sketch. The library used by the original sketch will not work here. Also, you have to install the LiquidCrystal library.
It is a complete radio capable to tune LW, MW, SW on AM and SSB mode and also receive the regular comercial stations.
