I am a commercial diver. I dive a Kirby Morgan SL 27 daily and a OTS Guardian both with Communications we run two wire with our umbilical carrying our surface supplied air. For all of you with some electrical background, how do I build a home made comms box... I’m guessing it’s like a 9 or 12 volt wired intercom. Speaker doublers as a microphone...I’m just not sure what I need, such as amplifiers, resistors, or anything like that. Any help would be appreciated.
