Installing IFace inside the TS-2000 – VHF and UHF bands

In a previous article we presented how to install the IFace card inside the Kenwood TS-2000 to obtain the IF signal of the HF and 50 MHz bands in order to send it to an external SDR. Now let’s see how to get the IF signal for the VHF and UHF bands. Installation is very easy.

The result you can obtain is well shown in the following video.

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 VHF and UHF bands.

The point where the IF signal is taken can be identified more precisely using the electrical scheme as shown in the following images. The electronic card of interest is the one named TX-RX2 and the signal can be taken R167 or C233.

Now we need to find out where to get the power supply: energy can be taken from the CN 12 connector or from the CN 17, 14S signal.

  • PTT: for the TS-2000 it is not required because the reception circuit is automatically muted during transmission.

In the images that follow you can see the points where to take the IF signal: therefore the installation is really simple.

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.

ICOM IC-7600 SDR!

Our friend Alfredo EA5YJ sent us some pictures of the installation of our universal SDR interface IFace inside the great ICOM IC-7600. This is a very powerful testimonial and we like to share it to thank Alfredo: the work has been done in EB5AGV Jose Vicente’s lab.
In this way, using an SDR1A and its software you can take advantage of all the advanced features of the SDR receivers and improve the performance of any radio!

And if it works with an IC-7600… it works with any radio!

Here below you can see some pictures of the comparison between the spectrum as shown on the display of the radio and on the screen of an HP spectrum analyzer.

The installation is very easy, the instructions can be found here, and from the following images you can see result of the installation made by EB5AGV Jose Vicente.

If you’d like to buy an IFace please use the following button. A shopping cart will appear and you will be able to proceed with the order.

If you want to find out for which other radios the installation instructions are already available, go to this page.

If you do not know which SDR receiver to use and you want an advice, please note that all our tests were carried out using one of the receivers shown in this article: click here.

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

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

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.
