New receive antenna socket for IC 7300
IHSG and Vibroplex/INRAD announce the release of a new accessory product for the Icom IC-7300 which provides a receive antenna socket on the rear of the radio.
The INRAD model RX7300 allows the user to add a receive-only antenna jack to the Icom IC-7300. This easy to install plug-in modification requires no soldering and is simple to install and easily reversible. The RX7300 can also be used for the insertion of accessory items into the receiver chain on the IC-7300 like receive-only bandpass filters, low noise preamps, etc.
When installed, the transceiver will use the SO-239 antenna connector on transmit, and one RCA phono jack on the RX7300 for receive. To use the transceiver in normal operation via the SO239, leave the RG-174 coax loop installed between the 2 phono sockets.
The RX7300 retails for £49.95 or £99.95 fitted and is only available through HIS group affiliated stores. Customers who purchased their IC-7300s via an IHSG store will receive a £5.00 discount from the supply only price and £15.00 discount from the installed price.

You should not – the unit you purchased is inserted behind the IC-7300 t/r switch.
Thank you Ken for your reply.At the moment I have a rsp1a and a ptrx7300 fitted ,I don’t like using it as the computer mouse is not good enough to pick out the signals on the computer screen,and I find the receiver on the 7300 better than the rsp1a.I am going to take ptrx7300 out and rsp1a and fit rx7300.Regards Alan
With the rx7300 fitted does my ic7300 still need a automatic antenna switch fitted in coax to stop transmission into the recieve antenna.Regards Alan .
Why didn’t Icom just have two antenna jacks?
There is no antenna socket on your picture above.
It shows the right instead of the left side of the back side.
The receive-only antenna port is one of the RCA type ports in the photo, not an SO-239.
The ‘kit’ requires that you remove the AH-4 antenna tuner connection and re-use the opening to hold the dual phono jacks.
The ‘kit’ installs without soldering by intercepting the receiver ‘feed’ line and routing it through the phono jacks.
Some owners may wish to employ a ‘fake’ tuner ‘plug’ that simulates the presence of an external tuner to allow them to use the tune button on the radio to put out a low-power carrier to trigger RF-sensing Auto-Tuners.
