SDR interface for FTDX1200

Follow the steps below to install the IFace card in the YAESU FTDX-1200. Installation is really very easy.

As always we start from the block diagram and try to find information on where to get the first intermediate frequency signal. We use the first because it is not filtered, i.e. the band is still wide. The following images make it very clear where this point is located. The PTT may not be necessary, the TX and RX circuits are well separated. The power supply can be taken from a point very close to the relais labeled RL1007.

At this point all that remains is to identify the points on the PCB where to take the signals: refer to the following images.

With the video below you can also view the instructions and listen to the explanations on how to install the IFace

WARNING: Although the installation of IFace is not difficult, it is done at your own risk. TSP S.r.l. is not responsible for any damage, unwanted side effects or anything else.
