[PSUBS-MAILIST] Comms for the SeaQuestor Sub

Wed Aug 1 23:08:49 EDT 2018

I'm guessing here, but I think in general any headset/mic with PTT capability intended for intercom purposes should be able to be modified for OTS use.  The mic uses only two wires as does the audio (mono).  The OTS "hi-use" waterproof connector, which they sell for $69, could be replaced with an XLR-4 microphone connector.  We already know we can get the connectors that attach to the SSB-2010 unit.
The interesting part would be how the audio quality from a $50 "walmart" unit matches against the $500 OTS unit.  I suspect some cheap units are not going to perform all that great, but it would be an interesting experiment.

Hi Alan,
Unfortunately, there is. One of my friends who helps out with the sub is an electrical engineer and some time ago took on, as a special project, figuring out how we might use a generic head set and mic with the SSB-2010. It was just to save money and make replacement readily available given how much OTS charges. He managed it, and it consists of a little bit of circuitry in a small enclosure with plugs for the headset and mic, and a push-to-talk button. The connector from the enclosure to the OTS unit we had to get from OTS, but luckily they sell that as a spare part. Now here's the bad news... because I'm not Cliff, Steve, or Jon, and because it was a one-off project, I'm afraid I don't have it formally documented. But if anyone needs this, I can open the box and draw what's inside.
Best,Alec

Cliff, I will shortly have 7 sets (3) for me which gives me a spare and 4 for others. I will put you on the list and let you know as soon as they arrive.

David, I would be interested in one of OTS head sets if you have spares.  One of my future projects is to integrate my vHF mic into the OTS headset .

Headset with boom mic?  Connects to STX-101 or SSB2010?  I'd probably be interested in one or two.
Pretty sure we were using the OTS headset in Cliff's R-300.

I just purchased my comms gear for both topside and in the sub. I might have the opportunity to get some additional headsets for the ots. If anybody is interested let me know.Looks Like I can get them for $200 each, 6 sets available. Any takers? Has anyone used the topside headset with boom mike for the SSB2010 in the sub.? 

Purchased "Aquacom SSB2010 for the sub, OTS Headset with Boom Mike, and OTS  STX-101 (4) channel surface unit with mike and transducer. Gotta love Ebay. 

I sent this earlier with jpg attachments but the email server must limit attachments.
