Is there a transmit calibration to do once I add this mod?
No difference with LSB or USB while in transmit ...still the same DDS vfo output signal....terrible distorted audio!
What about changing the Raduino code to reflect the shift in TX?? I am using v1.28.1?
LSB?? 4.81329 MHz DDS output looks like a square wave!
USB?? 19.1917 MHz DDS output
Just detected something else:? When I let go of the PTT the frequency drops100Hz each time!
Anyone know what the purpose of the blue pot on the Raduino...contrast ?
Help...please!
