Remove all 10 screws on the top cover and 2 screws from each side.
Top cover removed. We’ll be looking at the rear of the radio.
Lift out the antenna tuner jack. Pull the cable (TMP connector) out of the jack (J1701) closest to the front of the radio and plug it into the female TMP connector.
Plug the cable from the RX7300 into the vacant J1701 jack in the radio. It is a little tough getting these into the jacks.
Slide the RX7300 mod into place. Let the external antenna tuner hang out of the rear. As a precaution use a little electrical tape to protect the wiring harness. Do not tighten down cover screws at the rear.
Finished product. I connected my LDG to the tuner port and all is well. Try this at your own risk!
I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.
