Yup, good points.
I think in a case like this, verifying it is in receive mode (check TX and RX),
and getting the receiver to work is the first step.
Lots of things could make it decide to go into transmit mode,?
but especially your resistor at the key jack, and PTT wiring.
I'm not sure what all is going on with sidetone levels here.
Had been complaints early on about it being too loud, then R253 got changed.
Best to get it going first with the stock firmware.
Should not be necessary to do any mods to get a working radio.

Hi Jerry,
One of your questions was already answered and you even requoted it. He said there is no audio in the speaker nor in the earphones. It could still be wired wrong.
In my V3 with CEC software there is a setting in the setup menu to disable the transmit. I thought I would use that to play with the sidetone and use the uBitx as a $150 code practice oscillator. There was very little sidetone, extremely faint. I don't know if his software has a feature to disable the transmitter. He may also not have wired the brown wire to the power supply so there is no drain voltage applied to the finals. No transmit output.
And what about that resistor to the key jack? That produces at least some of the symptoms. Other hams have decided they don't use CW and don't need that resistor. WRONG! There new rigs worked right AFTER they installed that.
I hope all of this helps him make progress toward a working radio.
