[Milsurplus] SIMPLE Carbon Microphone Substitute.

[Hubert Miller]

What’s the resistance ( or any spec ) of those tel operator headsets – the early ones, not the late Plantronics style – you describe? With the smaller button than the F-1

element? I have several of those headsets around. I think the headphone part is 350 ohms Z. 

Which reminds me again, i have a factory box of new F-1 elements i should do something with.

I have a couple of Motorola mikes from some sort of portable belt-clipped transmitters, perhaps railroad used items.  Are those similar to what you were thinking of?  Their mike buttons are marked Roanwell RN-1, which is the same as a generic N-1, the button used in those old switchboard operator headsets (think of the Lilly Tomlin telephone operator skit).
