The manual is here -

The OCT-3 is used to monitor FSK shift in RTTY transmitters. It is
basically a superhet receiver with two limiters and a discriminator whose
output is supplied to a VTVM which indicates the amount of frequency shift.
The audio output (phones) comes from the discriminator to aid in tuning, so
it is essentially an FM receiver.
Schematic is here - http://www.navy-radio.com/rtty/misc/oct.pdf

well as an OCT-3 RF signal analyzer at this time.  I will be disposing of
both.  Asking $50 each plus pick-up before Christmas.   Both are pristine
as used gear goes.  Will also consider donating these to a good cause.
Just get them out by Christmas.
