Just a suggestion: I found that the drive current line in my Raduino was commented out.? I removed the comment slashes and compiled with the current set a 2 MA.
I also replaced the two wires that carry the VFO signal from the Raduino to the board with a short length of RG-174U coax and the birdie is now completely gone.? Not sure which change killed it at this point.
