The Heil HM-12 microphone is designed specifically for amateur radio communications. The high-output, full-range ‘Genesis’ dynamic element is designed to work with just about every amateur radio low-impedance transmitter. The element is mounted in a unique internal shock mount and exhibits nearly –35 dB of rear rejection, which reduces background and ambient noise from the transmitted signal.
The HM–12 exhibits a very natural audio response and is designed to have the traditional Heil +4 dB peak centered at 2 kHz. This attention to detail results in excellent voice articulation balanced with clean, clear low-end response producing a high-quality AM, FM or SSB signal.
The HM-12 features a ‘soft touch’ PTT switch wired to pins 3 and 4 for transmitter control with the microphone signal fed to pins 1 and 2 of the 4-pin XLR.
The HM-12 microphone has an internal foam windscreen and includes a 5/8”-27 microphone clip that is designed for our booms and desk stands.
Please see our Product Compatibility Guide to determine whether the HM-12 is compatible with your radio and which CC-1 connecting cable is required.

I Use this microphone on my FTM 100D and now my FTM 500 D I get great audio reports.. I hear all the time why can’t I get a desk microphone for my FTM series Radio and I always say you can the radio company does not make them but Heil sure does my HM-12 is matched nicely with a Atlas stand and the proper cables from Heil. Works great with the Heil microphone Stands just as well!
