[Milsurplus] ID'ing a unit

[Mike Hanz]

Probably a dupe, but NAVSHIPS 900,109 of Sept 1945 sez:

"For use with TBW*.  Provides for starting and keying transmitter unit 
over a single pair, or one wire and ground.  Transmitter starts when key 
is momentarily closed and remains on for a delayed time interval after 
last key impulse is transmitted.  6/2/44"

There is an edit to this:

"Key line resistance 35 DC ohms max; operates from 115/1/60.  9 watts 
standby, 18 watts operating, keying speed 50 words/minute.  For general 
radio use."
