The following image shows the SDR# screen during the reception with a Kenwood TS-530s (its intermediate frequency is 8.83 MHz) and an economical RTL-SDR.Īnother IFace has been installed in a YAESU FT-450D. Powering the IFace with 12 Vdc from the radio (red wire)Īfter making these simple wiring, you can connect your SDR receiver and start the reception software.

The following images show how easy it is to install the IFace into the TS-530s. Obviously the buffer must be powered: it will not be difficult to find inside the radio a point where to draw a voltage of 9 Vdc or 12 Vdc. The “Output” instead will be connected with another small coaxial cable to the input of the chosen SDR receiver.

If the connection is very short, a coaxial cable may not be necessary. The connection to the chosen point can be made with a thin coaxial cable (type RG178 or RG316) and will terminate at the “Input” pad of the IFace. The image below shows the point where you have to connect the IFace interface in the case of a Kenwood TS-530s, a radio of a few decades ago, which can be easily updated with this interface.

The point where you take the IF signal is easy to find, just take the schematic diagram of your radio and look for the first mixer: at its output you will find the signal of interest. This helps to prevent saturation of the dynamics of RTL-SDR (which is not known to be the most extensive). There are numerous advantages in picking up the IF signal and not the one coming directly from the antenna: one of these is surely the fact that the amplitude of the signal is controlled through the AGC circuitry of the reception stages.

Once the IF signal has been obtained, it is sufficient to connect the A / D converter (an RTL-SDR is already more than enough) to the USB port and start the software for the reception (ex HDSDR, SDR #, SDR Console etc) and our RTX will now be equipped with a nice panoramic receiver.Īre you already convinced? Very well, buy an IFace immediately by clicking on the buttons below! The usefulness of this circuit is to allow the medium frequency signal to be replicated without increasing the load seen by the source (the mixer) and therefore without changing its performance. no calibration is needed, it is installed and it is ready to work. This is a wideband and no-tune buffer, i.e. The IF signal pick up card, the IFace, creates a copy of the signal to be sent to the external SDR receiver. For this reason we have to insert a special card between this and the external receiver: we can not connect it directly. In order to not alter the operation of our receiver, we must pick up the signal without charging the mixer, i.e.
