Today I completed the build of my uBitx.
Unfortunately the Opto coupler / VFO is unresponstive. No matter what I do it stuck at LSB A : 7150.00
I tried to push the the reset button on the small board behind the display to no avail.
On closer inspection of the manual I noticed a discrepency between the text and the picture. The text tells that the brown wire has to be connected to the Pin B of the opto coupler while the picture shows a purple wire.
Earlier in the manual it states that the purple wire from the Raduino board is redundant so I removed it...
Looking forward to your input!
