Firecom intercom and radio PTT headset repair / Electret condenser microphone element testing

Short video on doing a check and replacement of an electret condenser microphone in a Firecom headset. Initial complaint of bad audio following headset immersion in water.

"FireCom headset" but really a how-to on checking a condenser mic. Great vid - thanks!

Nice to see somebody still willing to repair equipment instead of just replacing it! Love the Knipex pliers & analog millivoltmeter!

[@survivalcomms]

Thank you very much. Fixing things is fun. Knipex is good stuff. Their pliers wrench is phenomenal. I got the AC millivoltmeter at the Florida Flywheelers Flea Market for 15 bucks years ago. It is a fantastic market for tools. Thanks for watching !

Clear presentation. FireComm unit but the technique can be used for any similar unit. Thanks!

[@survivalcomms]

You are welcome ! Pretty much everything that uses an EC mic can have the element checked in this way. David Clark and some other vendors need more bias voltage however. Thanks for watching !

That was a pretty cool video!

Thank you very much ! Thanks for watching !

Same Idea when using an aviation headset?

[@survivalcomms]

If it uses an electret condenser mic it is. Some use dynamic mics. What radio and headset are you working with ? Thanks for watching !
