FT-2000 with SDR panadapter

FT-2000 with SDR panadapter

Our buffer interface named IFace can be used to add an SDR panadapter to the glorious Yaesu FT-2000.

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 69.450 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 MAIN UNIT where we can see the exact points where to sample the IF signal and the power supply.

In the years, Yaesu produced several versions of the MAIN Unit. They changed the position of the resistor R1493, but the sampling point remains the same on the common contact of RL1019.

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.

In order to purchase an IFace use the buttons below.

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.
