Jerry,  he's talking about the typical tuning.  When you turn it quickly its programed to make large jumps.

I had thought the original firmware shipped with the rig was good enough.
Could look for trouble with a DVM or scope on the black and brown wires to the encoder (ENC_A and ENC_B in the wireup diagram),
should see each wire periodically switch between 0 and 5v when slowly turning the knob.
They get pulled high through resistors internal to the Nano, and the encoder sometimes shorts them to ground.
