Si5351 + Si4735 DSP Radio Double Conversion - Update SSB Reception

Si5351 + Si4735 DSP Radio Double Conversion - Update SSB (USB/LSB demodulation) added via Si4735 SSB Patch. The tuning of the HAM station is continuous and smooth, without sound cuts or muting (or the chuffing sound) typical of low cost DSP receivers. I integrated in a single sketch (Arduino) the control of Si4735 and Si5351. I used the Arduino Nano. ------------------------------- New tests with my development board: reception of the Si4735 DSP acting in double conversion and in this way the tuning of the stations is continuous, without sound cuts or muting (or the chuffing sound) typical of low cost DSP receivers. In the test I use the Si5351 clock generator as a local oscillator and send it to the Mixer SA612, which results in a 10.7MHz IF that is sent to the Si4735 AMI PIN input. The Si4735 in turn is tuned fixed at 10.7MHz, so the tuning is done in a continuous way by varying the frequency of Si5351. Another advantage is to use the filters and demodulation of AM or SSB done by the DSP. Note: the antenna used in the test is a piece of 7 meter electric cable stretched inside the house. 73!
