I was a TT in the Coast Guard, The Ships and Communications Stations used TTY for message broadcasts. I worked mainly on the ATT Mod 40, But Did play with the 28's (Mechanical) for a bit. When I EOE'd to become a high powered consultant, I think they still had some 28's (Due to reliability) in service in the USN.
