Exclusive to ML&S.   

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.

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

Maintains the original appearance with no drilling of case.

Easily removed & reversable for later sale if required

PTRX-7300 is utilizing active high impedance probing technique to sample bidirectional TX/RX signal line. Because circuit is just sniffing (not loading RF signal line), thanks to its high input impedance amplifier, it can not be sensed by the rig and has no adverse effect on normal operation. There is no 3 dB loss as in the case of power splitting approach to sample the signal. Amplifier is designed with state of art components for ultra low distortion and low noise. Active and passive components are from well-known vendors, such as Analog Devices, Texas Instruments, AVX, TE Connectivity, etc. Designed CAD model and manufactured product are shown in Figure 1.  Beside designing high performance amplifer, there is also need for proper connectorized access to RF signal line. Fortunately, IC-7300 has a connector on its PCB designated as J1431 where you can sample TX/RX signals. Antenna RX signal reaches this point after passing through input filters and low noise amplifiers. There is also low power TX signal going to Power Amplifier. TX signal level is low enough.
