> ITTY audio is feeding a receive audio patch panel feeding a 48-in/20-out audio switchboard feeding a Dovetron TU feeding a 24-loop black TTY patch panel in my radio room. That loop is patched through one of four trunk lines to a 24-loop red TTY patch panel in my teletype message center room. There it is patched to an autostart 28ASR (or any of a dozen or so other machines).

The CV-3510B transmit audio goes to a transmitter audio patch panel where it is patched to whatever transmitter is desired, currently an AN/FRT-70. Transmitter control is from a C-1004 switch box mounted on the 28ASR which goes to a control switchboard to the selected transmitter. The transmitter and receiver are patched to antennas via an RF patch panel.
