Aha! After reading the manual I decided to "reset the microcomputer" (tiny reset button on the bottom). I don't know exactly what was wrong, but it seems to work now.

Unfortunately the only repeater in town that didn't have a tone code on it is down while they rebuild the building the antenna was on. I found this problem today because I was messing around with .

Oh cool, my TM-201A doesn't seem to transmit or receive. I think the PTT key is wonky, it flashes the busy lights but they don't stay on.

Learning so much.

What's everyone's favorite antenna modeling software?

I want to know more about how this interesting real-world sci-fi device inevitably failed.

Phinney, Chief Radioman, U.S. Navy, who, having tried the system himself, in 1923, introduced it at the Pensacola, Florida, Naval Training School.
