Our buffer interface named IFace can be used to add an SDR panadapter to the Ranger RCI-2950.
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 several mixers, we are interested in the first of the reception chain as it gives us a broadband signal. The IF frequency is 10.695 MHz. 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 TX-RX UNIT where we can see the exact points where to sample the IF signal 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 and for the power supply for the buffer interface.
The use of PTT signal is not required, RX and TX signals are separated.

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.
