Panoramic receiver from Audio input

[yo2ldk]

Hi John,

First of all, Thank you for all this nice work in the HAM benefits,

My kindle request is if I can use pihpsdr just with audio input as receiver, my setup is and Elektor SDR board and as VFO SI5351 module so, I have just audio disponible I suppose the SI5351 cannot be controlled like SI570 (will be nice if we can...)

 My best 73,
