Using External Antenna Tuners with the IC-7300 – Update …
2018年7月6日 · Apparently the IC-7300 uses current draw on the Tuner Voltage pins to determine that there is an external tuner connected. I have now done this with success. Once you get it setup correctly, the KAT-500 integrates very nicely with the IC-7300 and the IC-7600 transceivers.

Icom: - Compatible auto tuner for Icom IC-7300 - RadioReference.com Forums
2021年10月11日 · Icom makes 1 tuner and 3 antennas listed for the 7300. The AH-4 is designed for 80-6, depending on what you connect it to. Its intended to work with wire antennas, but isn't terribly wide banded. The AH-2b is a mobile whip to be used with the AH-4, and the AH-740 has a mechanical tuning base.

Icom’s IC-7300 is an awesome rig, but unfortunately the impedance range that the built-in antenna tuner can match is rather narrow (comparing to other Icom radios). Hopefully this is easy to change, i.e. make the tuner less restrictive regarding the antenna impedance.
ICOM-7300 Key Trait: It turns out that the ICOM-7300 senses the supply current drawn by an external auto-tuner, when that autotuner is connected to, and powered by the ICOM-7300. As a result, it disables its internal tuner and properly utilizes the external tuner – and by merely pressing the TUNE
Inrad RX7300 Modification On Icom 7300 Keeping External Tuner …
2017年6月18日 · The Inrad RX7300 is installed and I managed to keep the external antenna tuner jack on the rear of the IC-7300. All I did was let it dangle from the rear of the radio. This is temporary and I make no guarantees about this. The alternative is to provide power to the external tuner and use the tuner button on it. That has it's drawbacks.
External tuner vs balun & IC7300 auto tuner vs external auto tuner
2021年5月17日 · The IC 7300 will tune a 3:1 SWR normally and 10:1 when set to emergency mode. I have used that to tune an antenna off band and it works up to the point where the SWR exceeds 10:1. Note that the IC 7300 limits output power to 50W in emergency mode. Your dipole presents an SWR >3:1 and the IC 7300 cannot tune it.
