ICOM IC-775/775DSP SDR!

By in Radio accessories Tag , , , , , , ,

Our friend Luigi IV3XNF sent us some pictures of the installation of our universal SDR interface IFace inside the great ICOM IC-775DSP. This is a very powerful testimonial and we like to share it to thank Pellegrino.
In this way, using an external SDR receiver and its software you can take advantage of all the advanced features of the SDR technology and improve the performance of any radio!

This image shows just how our IFace works: it is used to take the IF signal from the radio and send it, properly processed, to the external receiver: this creates a real SDR panadapter.

And if it works with an IC-775… it works with any radio!

The installation is very easy, the instructions can be found here, and from the following images, you can see result of the installation made by IU8JAD.

If you’d like to buy an IFace please use the following button. A shopping cart will appear and you will be able to proceed with the order.

If you want to find out for which other radios the installation instructions are already available, go to this page.

If you do not know which SDR receiver to use and you want an advice, please note that all our tests were carried out using one of the receivers shown in this article: click here.

IC-7700 with SDR panadapter

By in Radio accessories Tag , , ,

Our buffer interface named IFace can be used to add an SDR panadapter to the Icom IC-7700.

The operations to be performed are very simple, it is sufficient to obtain from its wiring diagram the information on the points where to take the IF signals.

Testimonial by IU8JAD Pellegrino

This radio, in fact, uses different mixers. In particular, we will have to use the first of the RX chain. The following images show the block diagram of the radio. For the IC-7700 the first IF is shown in the small table in the following image.

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.

IC-9100 with SDR panadapter

By in Radio accessories Tag , ,

Our buffer interface named IFace can be used to add an SDR panadapter to the Icom IC-9100 transceiver.

The operations to be performed are very simple, it is sufficient to obtain from its wiring diagram the information on the points where to take the IF signals. This radio, in fact, uses different mixers depending on the selected band. In particular, we will have one for HF and 50 MHz, one for VHF and one for UHF (plus a fourth for the optional 1.2 GHz band). The following image shows the block diagram of the radio.

Below is a portion of the HF / 50 MHz reception chain and the list of the various intermediate frequencies: we are interested in the first one so as to have sufficient bandwidth for the panadapter. In HF/50 MHz we will tune our SDR receiver to 64.455 MHz, while in VHF to 10.850 MHz while in UHF to 71.250 MHz.

We now proceed to identify the exact points on the circuit diagram where to take the IF signal to be sent to the IFace. The following images show the sampling points of the signal for the HF and 50 MHz bands and of the power supply for the buffer interface.

Now let’s analyze the circuit diagram for VHF and UHF. It is easy to identify the two mixers and the relative points where to connect the IFace input.

The sampling points for the IF signal for the VHF and UHF bands are shown below. It is therefore clear that this radio requires 3 IFace buffer interfaces in order to cover all the available bands.

FT-818 with SDR panadapter

By in News, Radio accessories Tag , , , ,

A loyal friend and customer of ours sent us photos of the installation of our universal IFace interface inside his Yaesu FT-818.

If you wonder what an SDR panadapter can do for your station, watch this video.

This radio is practically the same as the FT-817, so the installation of the interface is identical for both radios. Now that little gem is equipped with an SDR panadapter which makes it an exceptional adventure companion.

Click here to access the installation instructions on this and other radios.

HDSDR settings for SDR panadapter and CAT control

By in Amateur radio, Radio accessories Tag , , , ,

Our IFace interface is used to add an SDR panadapter to any radio, present or future. The image below shows the typical application context where the IF signal of our receiver is sent to an external SDR receiver (in the specific case one from SDRplay).

The configuration we are going to examine is, therefore, the following.

We sample the signal after the first IF mixer but before the bandpass filter, the so-called “roofing filter”, and we send it to our IFace. This is nothing more than a broadband buffer that allows you to replicate the signal without overloading the mixer circuits. At the output of the card, the signal can be sent to an external receiver, typically an SDR, through a common 50 Ohm line.

At this point, there is nothing left to do but install the drivers for our A / D converter for RF signals and the demodulation software. In the specific case, we will use an RSP1 from SDRplay and the HDSDR program. In addition, through the CAT port, we can control our radio so as to have a perfect match of what we see on the screen with what we are receiving from the radio. The CAT interface is managed through the OmniRig software.

The main advantage is that of having a second receiver much more powerful than the internal one of the radio.

The following images show how the HDSDR program should be configured.

The result is also shown in a video where you can appreciate the reception quality and ease of radio control.

Panadapter SDR for the TS-440s

By in Radio accessories Tag , , , , ,

To install the IFace card inside the Kenwood TS-440s follow the steps below.

The TS-440s, like other radios, has a fairly complex configuration and uses different intermediate frequencies. We are interested in having a “wide band” signal, so it will have to be picked up before the main bandpass filter. The sequence of operations to be performed to obtain a bandwidth sufficient to realize a panoramic receiver around the chosen IF frequency (45.05 MHz) is shown below. The path of the TX and RX signals is partly separate, so the PTT command to disable the IFace during transmission may not be necessary. The following images show the point where the IF signal will be taken and the power supply.

Now we need to locate the points where to connect the electric cables to the IFace. The following images illustrate where to get the various signals on the RF UNIT.
