[Milsurplus] WRA-3 and Mystery equipment NAVSHIPS manual

[Nick England]

Yep, the final is a 4CX250B running class A (200ma @ 950vdc) driven by a
6CL6.
Output is 15W max or attenuated to 1.5W max when used as an exciter.
I am NOT making this up - this is one strange transmitter/exciter. And it
is 607 lbs with the shock mount base and stabilizer attached.....

Includes a 100 lb. freq synthesizer (O-1115/URC - 1 part in 100 million
stability) feeding the RF deck. The 100 lb p/s includes a 115v 400 Hz
output to drive the O-1115 (why did they choose a 400 Hz synthesizer?).

Aside from the mysterious "auxiliary equipment" input, the only operation
mentioned is CW with a key. No FSK, etc.

Just plumb weird....
