Its just a simple faced flange with an O ring seal. There is no step. Agreed, the clamps are a bit over the top, but i like heavy duty. There will be a vent somewhere. Probably a swagelok pipe into the hull, with a valve for diving. Thats all there is on Jodie B, just a tube into the hull with a cap you screw on for diving. Either that or a OP valve. Im not 100% sure how to put the power through into the hull actually. Options are: 1. Weld on penetrators like the K. 2. Blue Globe. 3. Swagelok pipework through into the hull with cabling inside running through a ball valve. In the event of a battery pod flood, pull the cables off and shut the valve. 4. Leave all the High Power cabling outside the hull and Blue Globe them direct to the motors. Only low power relay connections would then be required. I like this idea, but it wont work with the Engine generator inside. anyway, just thinking aloud now..

Once it is submerged, it is subject to hydrostatic pressure and likely not going anywhere. The retention really only needs to prevent it from coming loose when surfaced or out of the water, given the weight of the end cap and design accelerations / impacts of the sub. You may also want some capability to withstand internal pressure due to e.g. battery off gassing, but that could also just be an overpressure valve.

Salvage from an intact wreck involves either raising the entire intact wreck and moving it into water shallow enough for divers to safely penetrate it (lookup the salvage of the "Whine Maru") or demolishing the wreck, often with explosives or surface operated hydraulic grabs, until it's cargo can be removed. At the very least, your I would need a pair of hydraulic manipulators and some subsea rotary saws. You said something about nets on the wreck. Getting tangled in line or fishing net is extremely hazardous, and has resulted in atleast one fatal accident. Have you dove in a submersible before? I would gain more experience with submersibles before determining to build one. Where are you located? There may be a Psubbers nearby who can assist. I would not recommend making changes to the K250 drawings. The bottom viewport is not hard to fabricate compared to the rest of the hull. Depth perception through a downward viewport is also surprisingly important. I can never realistically judge depth to the sea bottom through a downward looking camera, but it is effortless through a window. If you want to look at a TV screen, you should build an ROV. I'm sorry if I read as overly harsh. If you begin this large of a project with unrealistic expectations, you will spend a large amount of time and money and walk away disappointed.

No Deep ocean salvage is usually limited to retrieving small items from the bottom. Salvage from an intact wreck involves either raising the entire intact wreck and moving it into water shallow enough for divers to safely penetrate it (lookup the salvage of the "Whine Maru") or demolishing the wreck, often with explosives or surface operated hydraulic grabs, until it's cargo can be removed. At the very least, your I would need a pair of hydraulic manipulators and some subsea rotary saws. You said something about nets on the wreck. Getting tangled in line or fishing net is extremely hazardous, and has resulted in atleast one fatal accident. Have you dove in a submersible before? No I would gain more experience with submersibles before determining to build one. Where are you located? Baja California Mexico There may be a Psubbers nearby who can assist. I would not recommend making changes to the K250 drawings. The bottom viewport is not hard to fabricate compared to the rest of the hull. Depth perception through a downward viewport is also surprisingly important. I can never realistically judge depth to the sea bottom through a downward looking camera, but it is effortless through a window. If you want to look at a TV screen, you should build an ROV. I'm sorry if I read as overly harsh. If you begin this large of a project with unrealistic expectations, you will spend a large amount of time and money and walk away disappointed. Thanks for the recommendations, i am working in a rov, the wreck is a well known fishing spot at 24 fathoms or 50 meters.i try the technical diving path, will not take anything as was a fishing tour vessel named Erick and 7 persons die and still there, the interesting part of this wreck, is bow up,stern down,was a 115 ft boat, bow is at 48 meters below on low tide.

I have the same issue with my MK2-DCI. The speaker is really just intended to provide situational awareness to other people in the vicinity by allowing them to listen in. It gets even worse from a diver tending perspective if you have to deal with helium voice without a descrambler. When used as designed as a surface unit, the primary tender / surface coordinator should be on a headset plugged in to the box. A large part of that is the exclusion of ambient noise (wind, voices, engine, etc.) that the headset provides, lowering the noise floor to increase intelligibility. Another big contributor to intelligibility is simply knowing how to speak on comms, in resisting the urge to talk in a normal flowing voice in favor of somewhat awkwardly separating and enunciating your words. Earbuds / indoor lightweight headset is probably not ideal for the surface, but may work just fine in the sub, because there isn't much in the way of ambient noise inside. I do wonder about matching the impedances of the OTS headset / microphone with a small headset in its place though. I have never actually measured what these are on the OTS headset. Typical earbuds as you might have with your phone are usually 8, 16 or 32 ohm. My studio headphones are 54 ohm. No idea about microphones. Probably okay as long as you have bidirectional volume controls, but you'll have to experiment.

Power will be a function of the amplifier circuitry. Easily doubled with a bigger amplifier, but at the expense of power consumption. Is the M version still rated as having the same battery life? The transducer is a ceramic ring with a resonant frequency close to the transmission carrier frequency, but it will be a tradeoff in efficiency as you move away from the optimal frequency. A transducer that has to cover down to 25 kHz I would expect to be somewhat larger than one that only needs to extend down to 31.25 kHz. I may be mistaken, but I think the four channel units are optimized for channels 1/2 and are less efficient at 31.25 kHz. The eight channel units I might expect to be optimized for somewhere in the middle (29?).

I think part of that reason is because the STX-101 has a plastic/cellophane cover over the speaker to protect it from water splashes which adds a layer of timber distortion on top of that already inherent with side band comms. Add the hollow echo you get from being surrounded by steel and I'm not sure how clear it's going to be. Time will tell. I'm using the STX inside the sub as well, but for different reasons. Planning on bringing a headset just in case, but not the heavy kind OTS issues with their gear.

However, can the transducer handle the increased power? I wonder if the STX101 M (10W) has a different transducer! These units are designed for divers that need to carry a small unit & are not ( in general) going as deep or as far away as our submarines. DNV/GL stipulate that the communications unit should have double the range of the submarine. This is a bit ambiguous as sea conditions play a big part in the coms range. We have the advantage over a diver of a large power source, so why not utilise that & look at increasing the power & range? Alan > On 12/11/2020, at 3:28 AM, Sean T.

A transducer that has to cover down to 25 kHz I would expect to be somewhat larger than one that only needs to extend down to 31.25 kHz. I may be mistaken, but I think the four channel units are optimized for channels 1/2 and are less efficient at 31.25 kHz.

The same one that Vance was just asking about.? I believe he graduated high school the same year George died, so he would be between 28-30 now, possibly still living in Rockland.? Kittredge left the UEM to Ian but as I recall Ian had little or no interest in it and was going to try to sell anything he could to help pay for college.? He was a very nice kid and always helpful to George which is why George "rewarded" him by giving him the UEM and whatever else went with it.? Possibly plans, but the UEM is a K-250 without motors so if you've got K250 plans or own a K250, you've also got a UEM. I can guarantee there were no AutoCad drawings of any Kittredge plans that came from that era.? If there were, PSUBS would have them.? George had the original plans converted to PDF and that's as far as he got with them.? We investigated converting them but back at that time it was extremely expensive and nobody was willing to put the money up for it.

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.

Message-ID: Dave, As per yours and Alec"s reflections on how to have comms with two people in a sub, this is why I converted a Soniwave surface unit for inside Harold. The plan is to swap that out with an OTS surface unit I picked up inexpensively. I like the idea of a handheld microphone and a speaker as that frees up my ability to also listen in on my hydrophone.

In-Reply-To: References: <1365616244.263719.1605880450531@mail.yahoo.com> Message-ID: David, I suggest a momentary switch (push button) located somewhere convenient (e.g. on the headset or on a control joystick that your hand is on anyway) for PTT, and then a full switch somewhere else that you can toggle to force full duplex (continuous transmission). You might also find that there are physical switches available that can perform both functions, where it acts like a pushbutton when you only press it e.g. halfway down, but will latch if you push it all the way.

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.?

Looking forward to seeing what you come up with!?I like the idea of the push button on the controls.?Alan On Saturday, November 21, 2020, 06:47:23 AM GMT+13, Cliff Redus via Personal_Submersibles wrote: 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.

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.

Nothing too complicated, but I had to put together a little board with a few resistors and capacitors. One of my adapters has stopped working, I think because of the OTS cable failing with age. It?s one of my winter projects to redo it, so I?ll be sure to document the adapter.

SSB-2010, or in fact any acoustic unit, will be PTT only. Only 4-wire hardwire systems can run full duplex, so you never want to latch / switch your PTT in the sub to be always on, lest you not be able to receive any transmissions.

I just realized I gave bad advice to David about latching the PTT, because I wasn't thinking straight. SSB-2010, or in fact any acoustic unit, will be PTT only. Only 4-wire hardwire systems can run full duplex, so you never want to latch / switch your PTT in the sub to be always on, lest you not be able to receive any transmissions.

The newer models we were looking at on Psubs FB were rated to 300ft. I would guess they factor in a safety margin. As you say, they don't have a max depth for the top side transducer, they just quote the length of the cable. I'm just concerned that the transducer designed for top side use mightn't be as depth capable as the smaller transducer designed for diver use. This would be a good question for OTS technical dept. if they answered questions!

The more potting compound you put around the transducer the more it's going to impede the signal, so the logical approach would be to put less around the Topside transducer that is not going deep & more around the diver unit.

See link to document, below. For the STX-101, that's 35 feet because the standard cable length is 35 feet long. For the SSB-2010 it's 300 feet because that's about the limit for deep technical diving. You can see from the chart that the transducer with 55 foot cable is rated for 55 feet, and the one with 100 foot cable is rated for 100 feet. These ratings make sense from a marketing perspective but I have no concern that these are even close to actual failure depths. For example, Cliff gave the R-300 a 400 foot unmanned depth test in Lake Tahoe with his OTS transducer attached. Surface unit performance is going to be negatively affected by signal loss and potential electromagnetic reflections in the cable just like any transceiver/antenna system which is why you won't see a 1000 or 2000 foot cable option. The transducer units appear to be solidly potted and I suspect their failure depth is "deep". Certainly, I think there's no issue with it installed on any K-boat. > > https://www.oceantechnologysystems.com/wp-content/uploads/2019/08/OTS-Catalog52019-small.pdf > > Jon > > > On Friday, November 20, 2020, 11:17:35 PM EST, Alan James via Personal_Submersibles wrote: > > > Thanks Jon, > do you know the depth rating for the XTS-101transducer.

I'm still waiting for some parts so I can build a production example and videotape the actual fabrication.? It will literally be something like "Take the 10uf capacitor and solder it into the location marked C1"..."Take the 22uf capacitor and solder it into the location marked C2", etc, etc, etc. I did not have a problem ordering the Luminox LOX-2 O2 sensor that is targeted for this project.? I selected it because the specs were reasonable, it uses TTL Serial communication, it is factory calibrated, temp and pressure compensated, and it has a life of at least 5 years.? It's only weakness is that it is limited to 25% reading, however I rationalized that not only would a 25% reading be enough to indicate too much variation in O2 to justify surfacing, but that the Luminox could be used to calibrate a galvanic O2 sensor which could be used as a supplement for reading above 25%.? This then also satisfies those who want a bit of redundancy with O2 sensors.

The more potting compound you put around the transducer the more it's going to impede the signal, so the logical approach would be to put less around the Topside transducer that is not going deep & more around the diver unit.

See link to document, below.? For the STX-101, that's 35 feet because the standard cable length is 35 feet long.? For the SSB-2010 it's 300 feet because that's about the limit for deep technical diving.? You can see from the chart that the transducer with 55 foot cable is rated for 55 feet, and the one with 100 foot cable is rated for 100 feet.? These ratings make sense from a marketing perspective but I have no concern that these are even close to actual failure depths.? For example, Cliff gave the R-300 a 400 foot unmanned depth test in Lake Tahoe with his OTS transducer attached.? Surface unit performance is going to be negatively affected by signal loss and potential electromagnetic reflections in the cable just like any transceiver/antenna system which is why you won't see a 1000 or 2000 foot cable option.? The transducer units appear to be solidly potted and I suspect their! ? failure depth is "deep".?

Stevenson via Personal_Submersibles) Date: Fri, 27 Nov 2020 20:45:58 +0000 Subject: [PSUBS-MAILIST] Sensor calibration Message-ID: I just thought I would share a couple of thoughts regarding calibration, because I noted Jon mentioning possibly using a sensor with a 25% range to calibrate a galvanic sensor with greater range, and while you might be able to get in the ballpark for a linear calibration factor, strictly speaking this is not a proper calibration. In general, the range of your calibration standard should always match or exceed the range of the device you are calibrating, for a couple of reasons. The first is that while extrapolating a linear factor can indeed produce a reasonable slope estimate, you lose the ability to generate linearization data via lookup tables or polynomial corrections that are applicable within the calibration range once that range is exceeded. The second is that absolute error may be proportional to reading, but may also increase in the domain beyond the calibration range, and you are then unable to characterize this error in the extrapolated region. Calibrating one sensor against another one is subject to the accumulated maximum error of both, and while it may indeed be possible to obtain a very high accuracy calibrated sensor for use as a calibration standard, the more accessible standard for an oxygen concentration calibration outside of the laboratory is to use gases of known concentration at extremely high accuracy, and the easiest and most accessible standards to use are 100% inert gas (0% oxygen), dry atmospheric air (20.95% oxygen), and of course, 100% oxygen, because these are not subject to any sensor error. This gives you a three point calibration which, in contrast to a two point, will also provide some estimate of error in the regression, because the three points will never be perfectly in line. That error, in turn, can be considered the minimum error apparent in any two-point calibration performed within a lesser range using the first sensor as the calibration standard, and of course the second sensor can also be independently calibrated against appropriate gases at two points within its range, just using the comparison against the other sensor to establish error bounds. With CO2, in the absence of a custom reference standard calibration gas, you are limited to two point calibrations using oxygen or inert gas for 0 ppm, and atmospheric air for (as of today) 414 ppm. Again, for sub use you need to measure up to 5000 ppm, so this is technically not a proper calibration, because it extrapolates. To properly calibrate this sensor would require sourcing a certified high accuracy reference standard calibration gas, ideally at 5000 ppm CO2, so that your sensor calibration is entirely within the range of the calibration standard, and the three point calibration again provides you with an estimate of minimum error in the measurement. This may not matter to most of you /us, but I point it out just for the sake of information. It is always good to be aware of the limitations of measurements. An instrument which reads to three decimal places can instill false confidence in its accuracy if the error in that measurement is on the order of the first or second.
