Time-division multiplexer for use with TSEC/KO-5 crypto gear - it interfaces with 16 channel frequency-division multiplexer for RTTY.FUNCTIONAL DESCRIPTION The AN/UGA-1 is designed to accept multiplexed output of sixteen (16) channel multiplex equipment and divides it into sixteen (16) separate channels which are synchronously related to each other. Output on each channel is in six (6) unit synchronous signal. The receive portion of the equipment performs companion function.
RELATION TO OTHER EQUIPMENT The AN/UGA-1 is designed to be used with but not part of AN/UGC-3() for use on frequency division telegraph systems.
TYPE OF DIVISION: Time-division type.
TYPE OF OPERATION: Neutral.
TYPE OF ACTUATION: DC actuated.
NUMBER OF CHANNELS: 16.
NUMBER OF WORDS PER MINUTE: 60, 75, 100 words per minute per channel.
RELATION OF CHANNELS INPUT AND OUTPUT: The 16 channel inputs and outputs are synchronous in nature and are synchronously related.The KO-5 crypto system is a monster-On Thu, Dec 7, 2023 at 4:11 PM Hubert Miller <Kargo_cult@msn.com> wrote:______________________________________________________________Anyone familiar with the USN UGA-1 16 channel TTY multiplexer, used with the UGC-3 radio ?
I have a large ‘Teletype Corporation’ preliminary instruction book, and man does it look “prelim”,
with lots of sort of unpolished drawings. Lots of transistors. This must be for a VHF system, right,
or they couldn’t put that many channels on a signal ? Can someone give me the short version of
what this system was about ? Date on manual, 1960.
