SDR interface for the TS-450S and the TS-690S

These are the instructions to install the IFace interface inside of the Kenwood TS-450S/690S. The installation is very easy.

The TS-450S/690S, like other radios, has a fairly complex configuration and uses different intermediate frequencies. We are interested in the first, the “wide band” one, the one before the main band pass filter (the roofing filter so to speak). The sequence of operations to be performed in order to obtain a sufficient bandwidth to realize a panoramic receiver around the chosen IF frequency is shown below. The signal path for TX and RX are fairly separated, so to use the PTT command to disable the IFace during transmission is not required. The following images show the point where the IF signal will be taken.

Bloc diagram of the 1° mixer

Let’s start by analyzing the wiring diagram. We have to find the first mixer and where to take the power supply. From the following image everything will appear clear.

Electric diagram of the 1° mixer

At this point we have to locate the points where we connect the electric cables to the IFace. The following image shows where to take the various signals.

Layout of the RF UNIT

This last image shows the RF UNIT and where the IFace interface is to be connected.

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.

SDR interface for the IC-706

These are the instructions to install the IFace interface inside of the Icom IC-706. The installation is very easy.

The IC-706, like other radios, has a fairly complex configuration and uses two different intermediate frequencies. We are interested in the first, the “wide band” one, the one before the main band pass filter (the roofing filter so to speak). The sequence of operations to be performed in order to obtain a sufficient bandwidth to realize a panoramic receiver around the chosen IF frequency is shown below. The intermediate frequency filter is also used in transmission, so it will be preferable to use the PTT command to disable the IFace during transmission. The following images show the point where the IF signal will be taken.

Let’s start by analyzing the wiring diagram. We have to find the first mixer, the PTT and where to take the power supply. From the following images everything will appear clear.

PTT and power supply can be easily taken from the connector J10. The interesting signal are labeled as T8 and 13.8 respectively.

At this point we have to locate the points where we connect the electric cables to the IFace. The following images show where to take the various signals.

This last image shows the inside of the RTX and where the IFace interface is to be placed.

SDR interface for the IC-7600

These are the instructions to install the IFace interface inside of the Icom IC-7600. The installation is very easy.

The IC-7600, as well as other radios, has a fairly complex configuration and uses two different intermediate frequencies. We are interested in the first, the “wide band” one, the first one of the main band pass filter (the roofing filter so to speak). Below is the sequence of operations to be performed in order to obtain a sufficient bandwidth to make a panoramic receiver around the chosen IF frequency. Going over you can find some images that illustrate how to install the interface for SDR. The following image shows the point where the IF signal will be taken.

Let’s start by analyzing the wiring diagram. We have to find the first mixer, the PTT and where to take the power supply. From the following images everything will appear clear.

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
