[MRCA] WW2 Boom Mike Element

[MARK DORNEY]

The problem is the age of the mic. I’m using a newer mic, but the impedance is still too high ( above 50 ohms). I haven’t found a better replacement.

The ones I have used in my H-46/UR headsets are labeled M-51/UR and CW-292/U. It appears they aren't expensive - https://www.ebay.com/itm/M-51-UR-CARBON-MICROPHONE-ELEMENT-FOR-MILITARY-RADIO-NEW-Mfg-Audiosears-/263323881053 is just one of many sources.
