Our buffer interface named IFace can be used to add an SDR panadapter to the Yaesu FT-767GX.
The operations to be carried out are very simple, it is sufficient to obtain from its wiring diagram the information on the points where the IF signal has to be taken. This radio uses more than one mixer. The IF frequency of the first one is 45.03 MHz and our SDR panadapter will be tuned to this. The following image shows the block diagram of the radio and where to get the IF signal.
The following images show the portions of the schematic diagram of the RF UNIT where we can see the exact points where to sample the IF signal, the PTT+ (active high) and the power supply.
We now proceed to identify the exact points on the printed circuit board where to take the IF signal to be sent to the IFace. The following images show the sampling point for the IF signal, for the PTT+, and for the power supply for the buffer interface.
The use of PTT signal is required because some circuitry is shared between the TX and the RX signal paths.

ATTENTION: Though installing the IFace is not difficult, you do this at your own risk. TSP S.r.l. is not responsible for any damage, unwanted side-effects or whatever.
