 David, let us know what you discover from bench testing.Cliff

 Cliff, I have a spare headset that I am using for parts. It will be a perfect test rig for your idea which I like a lot. The vhf radio I have in the SeaQuestor unfortunately does not have a removable mic chord, so I will have to play around with the wiring a bit. I might be able to wire the switch in my flight stick which has a toggle feature on one of the switches. Time to build a test rig.
 Best Regards,
David Colombo

 I for one like the OTS combination headset and boom mike for operations inside my boat.  It feels rugged and robust.   As I am a one-man sub, I don't have the issue that Alec has of trying to listen to comms on the headset as well as a passenger in the boat.  Having said that, I do have one gripe with the installation on my boat. When I switch between  the OTS radio, with it's associated headset and boom mike, and surface comms using a marine VHF radio and speaker with its associated mike, I have to pull the headset off and leave it dangling on my neck.  The switching back and forth is bothersome.  As such, I took the OTS headset and boom mike apart to see how easy it would be to combine the operation of the two radios by utilizing the boom mike on the OTS radio for the VHF radio and piping the VHF speaker output to the speakers in the OTS head set.  The thought was to add a switch to the OTS headset or to VHF radio case to switch between VHF and OTS comms. This would solve the problem of switching between radios when diving or surfacing. The electronics in the OTS gear looked straight forward to understand but I got distracted on other stuff and never finished the project.  I have no experience with audio electronics so was unsure if the mike and speakers were compatible.   I am still interested in doing this so if someone with audio electronics expertise on the list  wants to take a crack at it, I would be willing to lend the my radios and OTS headset.  Contact me off list at cliffordredus at sbcglobal.net if you want to discuss.

  David, let Hank have it.  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.

 Nice score Sean.  That is an excellent price point for that unit second hand.
Alan, I, and a few others have discussed a DIY conversion in the past.  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.
We have talked to OTS in the past and they were not willing to provide PSUBS with a discount.  Likewise, I personally spoke with the owner of DiveLink years ago and he flat out told me, no discounts.

 Congrats on the price (compared to new anyway)!
The $730 price tag for the CDK-6 is a bit tough to swallow.  The transducer extension cable is $270, sothat's $460 for the head phones, microphone and headset connector...
If we could source (or design) a compatible connector we could potentially save $100s by building out ownsurface conversion kits.   Since the transducer extension cable comes in a 55' length, it would be used tomake many conversion kits.  For the connectors, if they are for using inside the sub, they don't need to bepressure resistant connectors, they just have to work properly, if not thing is available off-the-shelf we coulddesign and 3D print a compatible connector.  But for the end attaching to the transducer we would definitelyneed something that is pressure resistant.  Might not be feasible, but given I'll likely have to buy two CDK-6sets it seems worth exploring.
Has anybody talked to OTS about psubs?  Might they be interested in helping us?  
Cheers!  Ian.

It was me. Having a second unit will allow me to test them against each other now to see if I inadvertently bought a dud.

That said, now I need to decide whether I want to buy a CDK-6 conversion kit to gain wireless 1:1 surface to diver capability, or upgrade my second FFM with comms for wireless 1:1 diver to diver capability. I already have hardwire surface to diver comms, so I'm leaning towards the latter. 

This is getting to be an expensive experiment.

Did somebody on psubs get it?  
It ended up selling for $485.00, which seems like a great deal compared to the other offerings.

Hi Sean,I might next week. I will let you know if I do. I will ultimately need one for the SeaQuestor, since I borrowed it for the yellow sub.

David, are you bidding? Otherwise I will, again maxing out at about 1/2 of MSRP.

Up for grabs is a really clean SSB-2010 transceiver. Not the smaller, less powerful buddy phone.
