The Heil AD-1-IHT adapter cable allows you to use your favorite Heil IC headset with the Icom 705 transceiver.

The AD-1-IHT features a 1/8” microphone jack, an inline push-to-talk switch, and terminates in a 2.5mm plug for the microphone input on the Icom IC 705. (The headphone speaker output of your headset plugs directly into the radio).

The AD-1-IHT is designed to work with Heil IC headsets only. The AD-1-IHT is not compatible with dynamic headsets.

The AD-1-IHT is 11” in length.

The 705 does have 3 V bias power turned ON all the time, even if 8v is turned off.  This has resulted in a false keying issue. Go into your menu settings and then under connectors, make sure bias power 8V is turned ON.
