High-quality RF interface module allowing the Icom IC-7300 to have a pure RF signal output for connection to an external SDR receiver.

This revolutionary product has been in demand from IC-7300 owners from the very beginning but without an RF output it presents the user with a major drawback.  By adding this feature, the IC-7300 can be used with low-cost SDR’s like SDRPlay, HackRF, AirSpy & RTL-SDR.  

Easy to install in under 15 minutes with no soldering. If you would like us to fit please select the LAB-FIT option above. 

Instant set-up with no fiddling of menus or calibration.

Maintains the original appearance with no drilling of the case.

Easily removed & reversible for later sale if required

PTRX-7300 utilizes an active high impedance current-feedback probing technique to probe the bidirectional TX/RX signal line of IC-7300 (J1431). Due to the high impedance nature of the unit, it doesn’t introduce any insertion loss. Therefore there are no adverse effects on the radio side in terms of signal quality. In this method, there isn’t any 3dB insertion loss as in the power splitting approach to probe the signal.

 

During the design phase, we first measured the dynamic range of the TX/RX line (J1431) of IC-7300 in terms of both voltage and frequency. We extracted this information, used it to define the design specification of the unit, and finally developed the proof of concept designs with the help of SPICE simulations. In these simulations, we took into account both the signal integrity and amplification characteristics. With the help of a DDS-based signal generator (30kHz to 120MHz, @980mVpp), we analyzed the signal quality both in the time and frequency domain.

Our high-impedance probe has been designed with components from reputable distributors, such as Digi-Key in order to maintain the highest level of component quality. One of the major observations during the testing of the unit was that the input/output MCX connectors have a vital role in generating a signal free from distortion and attenuation. 

 

PTRX-7300 does not compromise external tuner functionality. That is, the schematics and the mechanical model have been designed for IC-7300 external tuner opening, which means that you can still continue using your existing external tuner along with the unit.

The unit bypasses the external tuner cables to the outside, so you keep the functionality of the external tuner signals. It requires 13.8V DC to operate. For this reason, we utilize the power rails from the external tuner cable to supply the unit without adding any external power source.  It consumes up to 30mA from external tuner cable so it does not disturb your tuner operations.
