IFace 2 – IF tap/pat interface

Would you like to have a radio with a nice 40 “LCD display where you can view spectrograms, waterfalls and much more information? And what would you say to have a modern SDR radio so that you can listen to more signals at the same time? Wouldn’t it be nice to have many digital filters to improve reception during contest or DX activity?

If you answered yes then IFace 2 is the electronic card that allows you to have all of this without having to buy a new radio. How? By inserting it inside your “old” beloved RTX and using a cheap SDR receiver for computers (some suggestions here) such as an USB RTL-SDR dongles.

IFace works with all the radios: click here!

Don’t you think so? Please watch this video and then keep reading.

The idea behind this product is to continue to use the radio that we have purchased and which has already given us so much satisfaction. Surely we already have the CAT interface with which we control it from the LOG or from other programs and we also have the audio interface for the digital modes. But sometimes we realize that we would need a second receiver (for example to follow the +5 kHz or + 10 kHz of a DX station), band filters with steeper sides to eliminate a disturbance on an adjacent frequency or a notch because our radio does not have it or it is not automatic. All this can be a memory!

So suppose to send the intermediate frequency signal (IF) of our radio to a dedicated SDR receiver and to start a program such as HDSDR (or SDR #, SDR Console …). On the screen of our computer we would have the spectrum display around the IF of our radio and, not to be neglected, we could also demodulate what it is receiving. But we could do even more, we could also demoulate other signals that are above or below the frequency tuned by our RTX.
Not bad, right?
The image below shows a screenshot of HDSDR connected to an FT-450D via an RTL-SDR and the IFace.

Reception at the IF frequency of a FT-450D though the IFace and a RTL-SDR.

What needs to be done is very simple. Let’s start by identifying within our radio the point where to take the medium frequency signal. This is between the output of the first mixer and the subsequent bandpass filters as shown in the following image.

After connecting the IFace to the mixer output, we supply it with a voltage between 8 V and 15 V (from inside the radio) and connect it to an external SDR receiver. During the reception the difference is strong, listen here.

In order to not alter the operation of our receiver, we must pick up the signal without charging the mixer, i.e. without taking power. For this reason we have to insert a special card between this and the external receiver: we can not connect it directly. The IF signal pick up card, the IFace, creates a copy of the signal to be sent to the external SDR receiver. This is a wideband and no-tune buffer, i.e. no calibration is needed, it is installed and it is ready to work. 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.

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.

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. This helps to prevent saturation of the dynamics of RTL-SDR (which is not known to be the most extensive). 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. 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 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. If the connection is very short, a coaxial cable may not be necessary. The “Output” instead will be connected with another small coaxial cable to the input of the chosen SDR receiver. 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 following images show how easy it is to install the IFace into the TS-530s.

After making these simple wiring, you can connect your SDR receiver and start the reception software. 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.

Another IFace has been installed in a YAESU FT-450D. As you will see from the photos, the space occupied is very little and the time required to connect the 4 conductors (+13 V, Gnd, Ptt +, IF) is a few minutes. In this case the Ptt signal was used, that is the “TX” signal present in the IF-UNIT of the radio. All this clearly appears in the following images.

IFace Vs IFace 2: because the differences are important!

IFace

  • power supply: 8-15 Vdc, I <50 mA
  • bandwidth: > 700 MHz
  • input impedance: > 500 kOhm
  • output impedance: 50 Ohm
  • power-down input ( PTT)
  • dimensions: 38 x 48 mm, PCB 1.6 mm

IFace 2

  • power supply: 8-15 Vdc, I <50 mA
  • bandwidth: > 700 MHz
  • input impedance: > 1 MOhm
  • output impedance: 50 Ohm
  • power-down input ( PTT)
  • dimensions: 31 x 39 mm, PCB 0.8 mm

In case you do not want to display any signal during transmission it is possible to turn off, by sending it into power down, the buffer of the IFace through a special input pin (PTT) as shown in the following picture. To be more accurate, an active high PTT, i.e. the signal is at a voltage greater than 5 V when transmitting, otherwise 0 V, or an active low PTT, i.e. the signal is at 0 V when the radio is transmitting, otherwise it must be floating, can be used.

The following video shows how the card reacts to the pressure of the PTT, that is when the radio changes from reception to transmission: the red LED indicates that the card is in power-down because the radio is transmitting.

If you were still not convinced of the goodness of this interface look at this other video where you can see how the IFace works when added to an old Kenwood TS-530s.

CW Stick Paddle – FAQ

If you still have doubts about the validity of our CW Stick Paddle, read below the answers to the most frequent questions we have received so far.

Q. What is the difference between the “standard” version and the “Black & Gold Limited Edition” version?

A. The two keys are identical in terms of circuitry, that is, the difference is the finish, the first green, the second black, and the “touch” metallization, the first tin-plated, the second real gold-plated.

Q. Is it a resistive or capacitive key?

A. It is a resistive key, it works by exploiting the surface resistance of the skin. Extremely dry or hardened skins have a very high surface resistance and may not work well: in this case, moisturize it.

Q. How fast can you use it?

A. It depends on your skills, but in general, in the configuration sold, it works well at least up to 30 WPM or more. If you want to go much faster, above 40 WPM, you need to replace two resistors (currently 10 MOhm) with lower values.

D. Does it need for power?

R. No! The power supply is obtained directly from the “dash” and “dot” signals, there are no batteries that discharge.

Q. Does it work with all radios?

A. Yes, but it depends on the voltages on the “dot” and “dash” lines. In general, 5 V or voltages close to this value must be found on the wires and transmission must take place by grounding (GND) one of these lines.

For any other questions, use the form below. Thanks.

IFace – FAQ

If you still have doubts about the validity of our IFace (click here), read below the answers to the most frequent questions we have received so far.

Q. What are the differences between IFace and IFace 2?

A. IFace and IFace 2 are 100% compatible. IFace 2 is an optimized version of IFace and is smaller. IFace 2 replaces the first version (which will no longer be sold).

Q. Can I continue to use the RTX without an SDR receiver connected to the IFace?

A. Obviously yes, the IFace does not influence the functioning of the radio in the least, it only serves to take a copy of the IF signal so that it can be sent to the external SDR receiver.

Q. What bandwidth can I see with the panadapter?

R. It depends, but above all, it does not depend on the IFace. It depends on the external SDR receiver you are going to use. For example, a classic RTL-SDR without decimation can typically reach 1 MHz bandwidth. An RSP1 can reach 10 MHz. If decimation is used, as we recommend, the band typically displayed is around 200 kHz (however more than enough for most applications).

Q. Is PTT necessary?

R. It depends, not always. It depends on the type of radio, in particular how the reception circuit is made. For example, if it uses part of the transmitter circuits then the answer is yes, otherwise if they are clearly separated the answer is no.

Q. What do “PTT Active High” and “PTT Active Low” mean?

A. Digital signals, such as the PTT signal, can be active high or active low. In the case of “active high” the PTT signal goes from 0 V to a higher value, typically 5 V or more. In the case of “active low,” the PTT signal goes from 5 or more volts to 0 V. Generally inside the radios the signal is “active high”. The “active low” signal is typical of an open-collector or open-drain transistor configuration.

Q. My radio does not have the CAT interface: at what frequency should the external SDR receiver be tuned?

A. In this case, if you do not use synchronization between computer and radio via CAT interface, the frequency to be used to receive correctly through the SDR panadapter is that of the IF to which the IFace is connected. Refer to the specific documentation for the installation of our interface.

Q. Can I use the CAT cable to change the frequency regardless of the VFO knob on the RTX or the software and have the same frequency value on both the SDR software and the radio?

A. Obviously yes, that’s what we recommend doing. If you use CAT to synchronize the radio and the SDR software, you will have full control of it directly from the computer screen.

Q. What kind of SDR do you provide in the bundle?

A. The SDR receiver that we have decided to provide in the bundle is what seems to us to be the best compromise in terms of cost, performance, ease of use, and the number of radios with which it can be combined. It is a clone of SDRplay’s RSP1. For more information read this article.

Q. Where do I connect the coaxial cable braid to the IFace?

A. It can be connected to one of the holes on the PCB or, if coaxial connectors are not used, to one of the pads where the external part of the connector should be welded.

Q. I have an RTX that already has an IF output. If I connect my SDR there, would I get the same performance as if I used the IFace?

A. No. Generally, with IFace, the performances are better because we can connect it directly after the first IF mixer and before the roofing filter. This results in a band displayed on the screen that is much wider than that displayed on the radio’s IF output.

Q. What do you need besides your IFace card to have a complete panadapter?

A. In general, you need an A / D converter for RF signals, also called an SDR receiver (ex. RTL-SDR or SDRplay) and a special program for the computer (HDSDR, SDR Console, SDR #, SDRuno etc.). That’s it.

The best SDR panadapter

After a few months of tests and various evaluations, we can claim to have identified the best SDR panadapter to combine with our IFace. We have tried cheap 8-bit products as well as much more expensive high-end products but this seemed to us the best compromise.

It is a small device to be connected to the USB port of our computers and allows you to digitize RF signals from 10 kHz to 2 GHz with a resolution of 12 bits. It works at a sampling rate such as to have up to 10 MHz of frequency band. It also features a 0.5 ppm TCXO.

Its technical characteristics are as follows:

  • continuous coverage from 10 kHz to 2 GHz
  • 12 bit resolution ADC
  • TCXO 0.5 ppm reference oscillator
  • up to 10 MHz of RF band viewable
  • low background noise compared to 8-bit devices
  • micro-USB 2.0 interface
  • SMA 50Ω antenna connector
  • it can also be used as spectrum analyzer (RF input power 0 dBm max)
  • compatible with all programs and drivers for SDRPlay RSP1
  • works with the most popular SDR software (HDSDR, SDR Console, Cubic SDR, and SDRuno)
  • case in anodized aluminum
  • power supply current from USB: 120-175mA
  • high quality/cost ratio

2 purchase options are available.
