[PSUBS-MAILIST] OTS comms headset.

Fri Nov 20 11:20:37 EST 2020

My gripe with the headset is that in a 2 person, if you have the headset on you can’t chat with the crew, and if you take it off for that reason you can’t hear when the surface calls. I use a little adapter box that has input from a hand mike, and output to a tiny Radio Shack amp about the size of a pack of cigarettes. A similar adapter is used on the surface, but in that case input and output are to ordinary headset with boom mic. I use SSB-2010 units both in the sub and on the surface.

Best,
Alec

I'm in the process of providing an open-source DIY version of my SEM project to the group as a community contribution so don't want to take advantage of the situation and "sell" it to you then make it available to everyone else for free a month later.  As well, I find the OTS headset overly heavy and bulky especially within the confines of the submarine.  That's one reason I'm interested in a lightweight alternative.

There's nothing magical about the OTS headset and microphone so should be many possibilities to use off the shelf "gamer" headsets as a replacement.  I plan on doing this with the STX-101 since I intend to use it with a headset inside the submarine, however I am not going to pay $460 for the OTS headset.
