The SM-J1 represents the pinnacle of ICOM's microphone lineup. Its refined design perfectly complements top-tier models such as the IC-7760, creating a unified aesthetic in your shack that elevates your overall operating experience.
Excellent frequency response ensures clear, rich audio with the signature dynamic microphone sound. Even in close-mic use, breath noise and plosives remain well controlled. Dual dynamic elements provide superior durability against shock, vibration, and environmental changes.
Unidirectional mode captures front-facing audio while reducing off-axis background noise—ideal for shared spaces or outdoor operation. When using this mode, bass frequencies increase as you move closer to the mic, which may affect intelligibility in SSB operation.
Omnidirectional mode maintains a consistent frequency response at any mic distance, ensuring natural audio quality and clear intelligibility. Perfect for rag chewing in quiet spaces. Moving closer to the mic also increases talk power for DX contacts and pileups.
The microphone detaches easily from the stand and can be mounted on boom arms*, freeing up desk space for other equipment. Using a boom arm also reduces the transmission of desk vibrations to the microphone.
User supplied.
Connect a commercially available footswitch to enable foot-operated PTT control. Free your hands from the radio and keyboard—ideal for contests where you can concentrate on Search and Pounce and logging for more efficient operating.

When I received my call sign a few years back, I was flooded with purchases of junk. Fast forward to 2019. I decided I wanted to build another option, not a dealer who has the same stuff as everyone else, but a dealer who actually uses what he sells. And that’s exactly what I do. If you see a product on this page or one of our tables at Hamfest, you can bet we have tried it and like it. From Radios to connectors we strive to bring you QUALITY. Sure, you can find it cheaper and we understand that, but if you don’t want to buy it again in 6 months, take a look at what we sell and have already approved. I am always just a phone call away.
