8-Pin MIC/Headset Adapter HS-01C for ICOM TRX(incl IC-7300) - ELECTRET
Works great with Icom 7410 and Excelvan BM800 microphone
The HS-01C adapter works great for my Excelvan BM800 and Icom 7410 combo. I also tried it with a cheap computer microphone and had similar decent results. Much better value for the money when compared to expensive brands like Heil Sound.
