SDR interface for the FT-897

Follow the steps below to install the IFace card in the YAESU FT-897. 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 soldering a thin wire on the fuse F1001.

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

If you are convinced of the goodness of the proposal buy an IFace using the button below.

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.

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.

An SDR for IFace

Several of you have written us asking which SDR receiver to use in combination with your radio and our IFace buffer card (which you will find here described). The answer is simple: all are fine and at the bottom of the page you will find some links to buy them.
In the 1 minute video here below you can find the test with a common RTL-SDR.

The basic concept of using the IFace buffer card is that the “dirty work”, that is to limit extremely strong signals, even outside the amateur radio band, is delegated to the first reception stages of our RTX. In this way we can also use a cheap SDR receiver, which in practice has no filters, of those from a few tens of $. Then, honestly, what we’re talking about is not a real receiver, but a part of it, because it’s an A / D (digital analog) converter, a lot of the work is done by the software on the computer. Here the choice is wide, there are many and those that we used for the tests that you have seen and read are SDR #, SDR Console and HDSDR.

The only recommendation is that the A / D converter is able to work at the IF frequency of our radio. Ex, if the IF is at 8.83 MHz we will not be able to use one that works from 25 MHz to 1700 MHz.

For the tests, and therefore for the results we showed you, we used either of these “receivers”.

SDR interface for the FT-991

Follow the steps below to install the IFace card in the YAESU FT-991. 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 the TP1034 near the J1018 connector.

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

SDR interface for the IC-R72

Follow the steps below to install the IFace card in the ICOM IC-R72. 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 take the first because it is not filtered and the band is still wide. The following images make it very clear where this point is located (on resistance R82). Being a receiver, there is no need to look for the PTT signal. The power supply can be taken between the inductance L66 and the resistance R68.

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

Finally, this photo suggests where to place the IFace card and where to get the signals.

TS-2000SDR: new testimonial!

Our client Alberto IK0ZTL just sent us a nice testimonial on how he used our IFace card to add an SDR receiver to his nice TS-2000.

He did a great job by inserting everything into the radio, including the RTL-SDR converter, so that he only had the USB cable out to connect to the computer.

Find all the nice work described in a PDF to download right below.

Instead, to buy an IFace, use this following button.

Good reading, congratulations to Alberto and good listening with SDR technology.

SDR interface for the IC-756PROIII

These are the instructions to install the IFace interface inside of the Icom IC-756PROIII. The installation is very easy.

The IC-756PROIII, as well as other radios, has a fairly complex configuration and uses three 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 a video with the sequence of operations to be performed 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.

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.

Installing the IFace inside the FT-857D

These are the instructions to install the IFace interface inside of the Yaesu FT-857D. The installation is very easy.

The FT-857D, as well as other radios, has a fairly complex configuration and uses 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). The one described here is therefore the sequence of operations to be performed to obtain a bandwidth sufficient to make a panoramic receiver around the selected IF frequency. The following image shows the point where the IF signal will be taken.

The PTT control is not required because different paths are used for the TX and the RX signals.

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 images everything will appear clear.

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.

The output signal cable can simply through one of the ventilation holes as depicted here below.
