The operations to be carried out are really very simple, it is sufficient to obtain from its wiring diagram the information on the points where to take the RF signals. In this case, in fact, we will not pick up the IF signal because this radio has such an architecture that the IF frequency is not constant but varies as the working conditions vary. So what we will get is a replica of the signal arriving from the antenna, suitably filtered by the band filters. The frequency that we will tune with our SDR receiver will be the same as that of the radio and not that of the IF. The following image shows the block diagram of the radio and where to take the IF signal.
The following images show the exact points in the wiring diagram where to take the RF signal, power supply and PTT. This is required to limit the RF signal entering the SDR panadapter during transmission.
The points on the PCB where to connect the IFace board are shown below: the RF signal, the power supply and the PTT are required: do not forget the return to GND of the power supply (which can also be obtained from the coaxial connector if in contact with the radio chassis).
The use of the PTT signal is required in order to disable the buffer as the SDR receiver will be tuned to the same transmission frequency and it is therefore necessary to protect it from signal excesses.

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 purchase an IFace use one of the buttons below.
Thank you Gianni IK0AZG.

Another very important testimonial has been sent to us by IZ4AQT Nicola and we can never say “thank you very much” enough. 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.
