Headset with Switch Box

Recently I am using a computer headset for my radios, it works great and have good audio report around. I also made a small box to switch over three radios, that help not to have too many microphones on the shack table.

Compare with my Heil Proset Plus, it is more light weight and comfortable, especially in the hot and humid weather here in Hong Kong.

However, the mic input level need very careful adjust because of high level output from the electret condenser microphone.
