[PSUBS-MAILIST] Adding an OTS surface unit inside sub

[Brian Hughes via Personal_Submersibles]

For the Psubs crowd the standard is 32.768 kHz, that's channel 1 or the "sport channel" on OTS systems. Ocean Reef uses the same frequency as did Soniwave before they went out of business. Nearly all of the Aquacom systems will have that one, except for the military versions.  All of my gear is discontinued, but it works well and was way cheaper than new.

Helle and Scubaphone (Orcatron) use 27 kHz, at least that's the standard for them as I understand it. I have two Scubaphone surface units gathering dust as I was going to install them, but learned PSubs uses OTS channel 1. That way all our subs can talk to each other. Cliff has the pinout designation on the PSubs site.
