""Most likely used for KW37s. A KWR37 receiver used around 500 submin
tubes, and there was at least two of them (and usually more) on every
ship and shore station in the Navy. Transmitters (which used roughly
1600 of the little buggers) were located at every communications and
intelligence site on shore. These were still in use in 1980 when I got
out of the Navy, and I have heard they were finally retired in the
1990s.""
