The 3rd output can be put to use as a CW tone generator. With multiple projects at hand I was hesitant to order one. The sketch was working perfect but no output from the breakout board. I rechecked the board for connection issues or soldering errors, everything seemed correct. So I set out to check the communication between Arduino and the SI chip. I burned this I2C scanner sketch to the nano and got no result on the serial monitor.

This made clear that there was no communication between Arduino and Breakout board. I realized the board was made for through hole components while I used SMD package. The Pin for both these packages is different.

This is what I got:. In the meanwhile if you have any suggestions or feedback, please feel free to post your comments in the section below. Actually I am eagerly waiting for the final version of this board so that all the hassle of a stable vfo and L. Shri Carudatta Uplap has said that the board will be ready soon. But your board seams to be in advance stage of design and testing. GR8 Amogh, I am sorry, was getting the boards ready, but then a tooth fairy gave me a Adafruit BreakOut Board and so the immediate need for the board was dropped.

Amongji good work…. Very nice! How was the performance of the rx compared to ad and Si? It was good. I dint find any specific issue with audio clarity. It is on par with the AD But I understand from reports that Si has some amount of spurs and is quite noisy compared to SI Also its performs well if only one clock is used or 2 clocks away from each other are used. But is not a bad choice over AD at all. SI is very clean and cant replace AD or Si I complied the sketch but found, it is giving error which I have pasted here.

I have no idea about programming, and where to look for answers, could you please let me know how to resolve this.OK, perhaps it's not quite as elegant as a "Q" creation, but hey, I can see Sean Connery pulling this little gizmo out of his pocket for some quick QRP action whenever there's a lull between seducing women and saving the world.

And one excellent example has been demonstrated by M0XPD in the United Kindom who made such a transceiver over a series of Arduino shields.
