[GreenKeys] TTY Today?

[David F]

Joe:


I don't believe anyone uses teletype machines anymore in day to day operations any more
than anyone uses CW, not even as back-up.


Listening to HF regularly, someone is still using RATT regularly, but I have no idea who
or what, as I have no way of copying any of it. At least, the "teletype" signals are there,
usually outside the ham bands. The ham bands themselves still have some active RTTY
too....


I was in the military for many years. When computers finally took hold, teletype equipment
was rapidly phased out. During the transition period from teletype machines located n
Communications Centers, the older equipment was held "in-place" for about 30 days to
make sure the newer computer gear worked. After that, those facilties were dismantled
and the equipment sent to PDO (Property Disposal Office), where is was auctioned off
(via the usual  DOD bidding process), mostly to junk dealers and metal scrap buyers and
recyclers.


It is highly likely that the military still has tons and tons of this equipment in storage
somewhere. We might hear about it in the next hundred years, once it is "found" again...


While a lot of printers, TDs and perforators have been preserved, NO tape relay
equipment has been saved anywhere that I am aware of, and that was a large part of
the teletype scene in years past, especially in the military services who operated
worldwide ("tape relay") teletype networks before computers (AUTODIN). Tape Relay
sets would include KLI AN/TGC-5, AN/FGC-30, AN/FGC-70, Teletype Corp Plan 55
systems, etc. (Earlier sets were the AN/TGC-1).

Hi again,


I was wondering if there are any TTY units / networks still in commercial or governmental use today. I know that a lot of private collectors such as myself preserve and use them regularly, but are any still in active use today?


I have always thought that when organizations upgrade to better comms systems, that they should preserve the old system for a backup. I feel this especially for the military.


Best,


Joe Herdler
