[GreenKeys] Dovetron MPC-1000CR/T "Regenerative Tempest" MIL-SPEC RTTY TU

[Rainer Haack]

Hello,

I have some questions about the Dovetron MPC-1000CR/T  "Regenerative 
Tempest"  MIL-SPEC RTTY TU unit:

What does the text  "Speed conversion is progammed OFF" on declaration 
sign of the military unit means and how can the speed conversion 
switched to ON?
How - if its possible - can I make a loop support for the TTY? There is 
no loop socket but a FSK socket on its back.
