Going for the longshot. Looking for a schematic for the speech processor board that ARF stuffed inside the base of the D104's they modified. Even a reverse engineered and drawn on lined paper diagram would suffice.

I'm guessing that the microphones themselves have been unobtainium for at least 20 years by this point. A dead one of those would be something to work from, but they're most likely all in landfills scattered around the country by now. Any working ones should be attached to the radio they came with, so I doubt the owner would want to disassemble it just to see what's in it. I'd appreciate it, but the odds are against it.

I've checked the service manual that's available online, nothing there unless I misinterpreted it.

Like I said, longshot. But I figured if anyone had the info, it would be someone from here.

Perhaps they had 2 desk mics to choose from. The ARF-2001 I owned had a D104 with an ARF tag on the front of the base, but the mic wasn't amplified at all.
