SDR interface for the IC-706MKIIG

By admin in RF Tag console, hdsdr, ic-706, icom, if, interface, panadapter, receiver, reception, rtl-sdr, sdrplay, sdr, tap

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

The IC-706MKIIG, like other radios, has a fairly complex configuration and uses two different intermediate frequencies. We are interested in the first, the “wideband” one, the one before the main bandpass 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.

If you like the idea and the goodness of the proposal buy an IFace using the button below.

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 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.

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.

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.

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

SDR interface for the FT-897

By admin in RF Tag console, ft-897, hdsdr, iface, if, interface, panadapter, rtl-sdr, rtlsdr, sdrplay, sdr

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.

Follow the steps below to install the IFace card in the YAESU FT-817. Installation is really very easy.

The power supply can be taken from the test point TP1084.

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!

By admin in RF Tag hamradio, hdsdr, iface, if, interface, kenwood, panadapter, pat, radio, rtl-sdr, rtlsdr, sdrplay, sdr, tap, ts-2000

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.

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