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

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.

https://youtu.be/W_3kcYuYjO8

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.

SDR interface for the IC-706MKIIG

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.

IC-7400 with SDR panadapter

Our buffer interface named IFace can be used to add an SDR panadapter to the glorious ICOM IC-7400.

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, we are interested in the first of the reception chain as it gives us a broadband signal. The IF frequency is 64.455 MHz. The following image shows the block diagram of the radio and where to get the IF signal.

The following images show the portions of the schematic diagram of the RF 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, RX and TX signals are separated.
