Changed USB charger inductor to smaller version
...
Original inductor recommended by manufacturer was for up to 14A (I_sat).
LinHT doesn't need currents like this, so smaller inductor for 8 A is used.
This will save some space as a new component is smaller in every dimension.

Fixed wrong pinout on the 3.5 mm jack

RX signal is on the same pin as PTT on the Kenwood style connector.

cable can be used to connect to the debug UART of LinHT.
