[R-1051] R-1051 Speakers

Thu Nov 21 17:55:55 EST 2019

They were amazing devices and agree on the wire. Though you could get fancy
and modulate a LED so your transmitting in the TeraHertz region. Chuckle.
Wires cheap maybe the easy way to go.
But even if hooked up you would need some current loop stuff to send
something. Or even more fun a T827 exciter to a R1051. Real radio as it was.
I would liked to have had one demod but never ran across them.
