    I just unboxed and hooked up my new Heil Pro 7 headset/mic for my Icom 7300. The result - no audio. Any suggestions before I contact Heil and/or HRO? Thanks!

    Which capsule and adapter cable did you order? If using an Icom, you have to use the Heil adapter cable meant for Icom radios that has the required DC blocking capacitor.

    Read all about it here: https://heilsound.com/heil-amateur-radio/support/dsp-settings/all-things-icom/

    My guess is you don't have the correct adapter cable and/or capsule.

    if your talking about headphone audio, plug the audio for the headset into a cell phone or similar and check see if you get audio that way, if you do, headset should be ok, if mic audio, no idea

    Also be aware that Icom radios supply voltage to the mike or damage could occur to the mike and the radio.
