Hmm, I Wonder Who was the Last O-Brancher to Operate an Afloat UYK-20 TACINTEL in the Pacific Fleet? I Might Know. More Like a Quarter Century Ago!

..."At both shore facilities and subscriber terminals, message traffic could be entered via the TACINTEL peripheral equipment such as the tape reader (not applicable to shore) or the display terminal keyboard. Most of the message traffic was entered automatically by systems or facilities connected to TACINTEL at those locations.
TACINTEL baseband equipment used an RF terminal in common with other subsystems at both the shore facilities and subscriber installations. The RF terminal at shore locations was an UHF Transceiver AN/WSC-5(V). At the subscriber installations, the UHF transceiver was an AN/GSC-3(V). The TACINTEL RF channel operated as a half-duplex UHF link, which could be operated at a transmission rate of 4800 Ups, 2400 bps, or 1200 Ups. The modulation of the RF signal is differentially encoded phase-shift keying (DESK)."...

You mean as a young CTR2, I might have assisted with this final watch? I mean, we CTRs stood watch with the CTO's and CTM's to maximize liberty away from homeport.
