Panadapter SDR for the FT-747GX

These are the instructions to install the IFace interface inside of the YAESU FT-747GX in order to add an SDR panadapter to the radio. The installation is very easy.

After removing the cover, locate the electronic board called “MAIN UNIT”: the signal we are interested in are on this board. The SDR receiver will be tuned on 47.055 MHz.

Refer to the following image of the wiring diagram to identify the points where you can weld the cables for the IF and the power supply. The PTT+ is not required, the signal paths for the RX and the TX are mostly separated.

Refer to the following images to identify the points on the PCB where to solder the various connection cables between radio and IFace.

In order to buy an IFace please use the following buttons.

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.

Installing IFace inside the TS-2000 – 23 cm band

In a previous article we presented how to install the IFace card inside the Kenwood TS-2000 in order to obtain the IF signal of all bands so that it can be sent to an external SDR. Now let’s see how to get the IF signal for the 23 cm band. Installation is very easy.

The TS-2000, like other radios, has a fairly complex configuration and uses different intermediate frequencies depending on the band on which you are operating. In any case, the one described here is the sequence of operations to be performed to obtain a bandwidth sufficient to provide a panoramic receiver around the IF frequency relative to the 23 cm band (1.2 GHz).

The point where to take the IF signal can be identified more precisely through the wiring diagram as shown in the following images. The electronic board of interest is the one called TX-RX3 and the signal can be taken from the CN8 connector.

The point where to take the IF signal on the TX-RX3 UNIT is indicated in the following image.

For the sake of completeness, a detail of the point where to take the power supply for the IFace card is also indicated.

PTT: This is not required for the TS-2000 as the reception circuit is muted during transmission.

You can purchase IFace 2 using one of the buttons below.
