The CLK 0 can be used as a VFO (100KHz to 160MHz) The CLK 1 can be used as a BFO (452KHz to 558KHz) #define RST_PIN -1 // Define proper RST_PIN if required. // Change this value below ...
[Tom Hall], along with many hams around the world, have been hacking the Silicon Labs Si5351 to create VFOs (variable frequency oscillators) to control receivers and transmitters. You can see the ...
