Re: Wiring encoder

Before messing around with the unsoldering/resoldering the connections, if you have the Arduino IDE installed and are comfortable with it, load the ubitx_20.ino source code file and locate line 75-76:

#define ENC_A (A0)
#define ENC_B (A1)

Try reversing these symbolic constants:

#define ENC_B (A0)
#define ENC_A (A1)
and see if that restores the proper rotation. Mine is all bundled up for a pending presentation, and I don't want to unpack it.

A word of caution when wiring the encoder. The schematic on page one
has the encoder wiring reversed. Don't wire it up by the schematic
use the picture, you will see that the red and yellow wires are reversed
and the black and brown are reversed. I made the mistake of wiring everything
up using the schematic. When tuning my frequency goes down with clockwise
rotation of encoder. Goes up with counter-clockwise rotation.
