IC-718 with SDR panadapter

Our buffer interface named IFace can be used to add an SDR panadapter to the Yaesu IC-718.

The operations to be carried out are very simple, it is sufficient to obtain from its wiring diagram the information on the points where the IF signal has to be taken. This radio uses several mixers and we are interested in the first IF frequency (this makes it easier to operate the panadapter). The IF frequency chosen is 64.455 MHz and our SDR panadapter will be tuned to this. The following image shows the block diagram of the radio and where to get the IF signal.

The following image shows the portions of the schematic diagram of the IF UNIT where we can see the exact points where to sample the IF signal and the power supply.

We now proceed to identify the exact points on the printed circuit board where to take the IF signal to be sent to the IFace. The following images show the sampling point for the IF signal and for the power supply for the buffer interface.

The use of PTT signal is not required because RX and TX signals are separated.

In order to buy an IFace use the buttons 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.

IC-7000 SDR by IK0AZG

Our friend Gianni IK0AZG has installed our IF buffer interface IFace on his Icom IC-7000 in order to equip his radio with an SDR panadapter. The following photos show some details of the installation, specifically how the buffer interface was shaped in order to be placed in the very little space available inside the radio (also for this reason the smaller and thinner IFace 2 was then designed).

In this image you can see the point where the IF signal is taken through the yellow wire.
In this image you can see the points where the power (positive red wire, negative black wire) and the IF signal (yellow wire) are taken.
In this image you can see the IFace buffer board suitably shaped to reduce the overall dimensions and correctly positioned and wired to the radio.
In this image you can see the output cable of the IF signal: it was chosen not to drill the rear panel of the radio and to use one of the openings on the back to pass the coaxial cable.

To view the complete IFace installation instructions in the Icom IC-7000 click here.

To purchase an IFace use one of the buttons below.

Thank you Gianni IK0AZG.

Panadapter SDR for the IC-781 with IFace v.2

Another very important testimonial has been sent to us by IZ4AQT Nicola and we cannot say “thank you very much”. Here below we propose his full report.


This description is intended to be complementary to the article already published for the same apparatus modified with IFace v.1. The solution described here advantageously takes advantage of the small size that the IFace v.2 interface “without connectors” has; in particular, the extremely limited thickness of the SMD construction made it possible to choose a location inside the “shielded box” of the RF Unit. Having used a rather rigid shielded cable (RG 316 / U), and the sampling point of the IF signal being particularly hidden, particular care had to be taken in the path and execution of the solderings. Primary objective: we must have curves of the coaxial cable sufficiently wide so as not to create excessive stress on the welding points. The photos below show the sequence of the implementation steps of the change.

Preparing the IFace for installation

In this phase the coaxial input and output signal cables and the power supply cable (in red) have been soldered to the board.

Check the overall dimensions in the final position

In this phase it was checked that the IFace v.2, suitably sandwiched between two insulating layers of plasticized cardboard, could easily find its place inside the RF Unit compartment.

Welding of the IF pickup cable

To facilitate soldering of the IF pickup cable, the RF Unit board has been removed from its housing so that the contacts on its underside can be easily accessed. The image below shows the solder side of this board.

The points where to carry out the soldering to take the IF signal and the power supply are shown in the following image. It should be noted that the welding, for convenience, will then be carried out on the lower side.

Uscita del segnale IF

In this image you can see the Teflon coaxial cable (RG 316 / U) for the output of the IF signal.

This needs to be brought up to the rear panel of the radio.

Before arriving at the output connector, an RF choke was inserted in order to prevent any propagation of unwanted signals.

This was made with two cylindrical ferrites as can be easily verified from the following images.

The choke was then suitably protected with heat shrink tubing (in green).

To bring the IF signal outside, it was decided to use the free “SPARE” connector on the rear panel of the radio.

This is accessible through special contacts on the printed circuit called “CONNECTOR 1”.

In order not to disassemble the “CONNECTOR 1” printed circuit board, it was decided not to solder the pins of the “SPARE” RCA connector and the end of the IF output cable from IFace v.2 was terminated with two golden female pins recovered from a military connector VEAM AMPHENOL.

At this point the work is finished and from the rear of the radio the IF signal is conveniently available and ready to be sent to the external SDR receiver (in the photo it is visible in blue).


Again a big thank you to IZ4AQT Nicola for this beautiful work of documentation of his installation.

JRC NRD-535: new testimonial!

With this article, we want to thank one of our beloved customers, Massimo, for his feedback after the installation of our IFace inside his JRC NRD-535.

He sent us some pictures and some suggestions. In particular, he wanted to share with us the idea to move the power supply point to another one on the contrary of that suggested by us.

This is because he experienced some noise during the reception on the SDR. The noise was coming from the processor and other digital circuitry, so he preferred to power the IFace from the +9V on the MOTHERBOARD. Please see the images below.

Thanks to him, we updated the installation instructions of our IF buffer interface for this great receiver: please click here to read it.

As said, for detailed instruction on how to install our IFace inside your radio, please refer to the istructions you can find here.
