| Most radios have just a mic input line and ground, so you'll need to take the balanced mic circuit and convert it to unbalanced. | Most radios have just a mic input line and ground, so you'll need to take the balanced mic circuit and convert it to unbalanced. |

| With electret microphones, [follow this diagram if hooking up to a Kenwood or Yaesu radio|http://www.kingsqueak.org/pages/2009-06-22-pc-headset-adapter-for-ham-radio.html]. The variable will be the resistor needed between Mic (before the capacitor) and Ground/Mic Ground. I noticed a several hundred ohm difference between two gaming headsets. Use a variable pot, or use a breakout board and test resistor values. Start low, in the hundreds first instead of 4.7k in the link. The lower the resistance, the quieter the mic will be. Keep your mic gain in the middle, and tune your resistance to match the volume level as best as you can. Use the ALC meter for your levels. | With electret microphones, follow this diagram if hooking up to a Kenwood or Yaesu radio (http://www.kingsqueak.org/pages/2009-06-22-pc-headset-adapter-for-ham-radio.html).
