The Dovetrons are two rack units which is 3 1/2 inches high.
I have two rack mounted ones. A military unit monitoring the receiver on my RTTY repeater. I use a polar relay on one of the polar outputs to key a 60 mil loop. The
other,
civilian one, monitors ITTY news 24/7 has its own loop supply and is available for testing Teletypes at any of three locations around here.
I would love to have one more civilian Dovetron for ITTY autostart. I pull both ITTY streams from one laptop computer that sits in a corner and runs 24/7.
