I find myself in agreement with Richard Spohn. I get really excited about trying circuit and firmware mods, and actually doing something on my own, rather than just plugging in a store-bought unit and

If you are not getting even a hiss with the volume control at maximum, then something is wrong in one of the two audio amplifier stages. ?Check for 12v to pin 6 of the LM386 at U1. ?Should see

The Arduino IDE makes it easy. You just load up the sketch and click the upload button and it compiles it and transfers it to the device via the USB cable. Practice this a few times before you start

Andrew, The default drive strength is 2mA. just curious: under what conditions did you try the different drive levels? Assumed (default) condition is a standard unmodified BITX40 board: - VFO on
