Re the radar comms: The more things change, the more they stay the same. We started out directing cones of light from signal lamps, they started shining cones of radar, we now are working on lasers, and we are right back to signal lamps, which still can’t be intercepted.

I live in Cleveland, OH born and raised and when growing up in grade school we had a wonderful field trip to tour the inside and outside of the USS. Cod which was such a fun informative tour of the submarine docked close to the Rock and Roll Hall of Fame and the Great Lakes Science Center. Burke Lakefront Airport is located right next to the USS. Cod. Some great tourist destinations within the city of Cleveland, OH. On a sunny summer day Lake Erie provides cool lake breezees along the lake shore and visitors may just travel a short distance to see all the cool places to visit along the Lake Erie shoreline. 😎 🎸👨👨👧👦☀️🌊🛥🚤⛵️🚢🛫🛬🚁📡🛰🎡🎢⚾️🏟🏈👍

As for the German radar detectors (sounds like something you'd want in your Porsche on the Autobahn), the Germans did not think, if I remember correctly, radar with a wavelength of around 10 cm could fit on a plane, but the Allies had the cavity magnetron (find one in your microwave oven today! Actually, don't take it apart). And the Brits would tell captured UBoat crews the emissions from the radar detector were being detected. Somehow that got back to Germany and many UBoats switched it off, allowing the Allies to use the older radar sets. (I think I read this in "Most Secret War", by R.V. Jones, head of British scientific intelligence in WWII. Fascinating read I picked up at a library sale many years ago.)

Another great video Paul. I see why you might get the radar working to transmit but what about the boat's radio system? That would be really cool. Also the trick of using the radar to transmit a radio signal was written about by Wayne Green in a booklet he published about life on a WWII fleet boat. Wayne was the publisher of a magazine called "Amateur Radio Today." Keep up the great work.

Bravo zulu from a USS NEW JERSEY volunteer. We all love to have fun and banter between ships, but the little things are important. The volunteers figuring out the little things…like those forgotten in documenting of SHIPALTS…are the reason these ships will keep working…and telling their stories for years to come. Keeping these systems working (when they had to operate after being underwater) is ONE thing that the surface ships don’t have to worry about 😅 Was great to tour USS MARTHA STEWART (I mean COD) two years ago, hope to come back later this month. 😊. Highly recommended for all in the Cleveland area! Beautiful boat.

It is a nicely footnoted and thorough paper and very readable. My link was rejected, so just search the title and you’ll find the paper at the Canadian Nautical Research Society.

We want to correct my interpretation of the red hash marks on our conning tower depth gage: the lower mark at 27 feet indicates bridge hatch dry, the middle mark is SJ dish dry and the upper mark is attack scope depth, which is the same depth as the SD aircraft radar.

Just a note - electrons are not transmitted; what goes up the waveguide is electromagnetic radiation - photons, but a much longer wavelength than visible light. Today, radars can steer without moving the antenna, using phased arrays or the more recent AESA - active electronically scanned array. But the steering range is more limited, which is why modern destroyers have several of them on the superstructure.

Kudos to MIT and all of the scientist who made all this possible, and Kudos to you for educating more generations about these things.

Thank you, Paul, Great video on getting the SJ antenna rotating again. BTW, why can Cobia have a working radar and Cod can't? You mentioned the FCC, but wouldn't that affect Cobia? I thought that Jig was the phonetic letter "J" in WWII. I sure could be wrong. I wasn't born until 1950 and never learned the phonetic alphabet until the early '60s. I think I can still remember it as well as the current one. I know I've made mistakes on occasion and slipped an old letter in when giving out a license plate or some-such. I offered to donate "Silent Victory" and "I-Boat Captain" to Cod and haven't heard back.

Cobia's radar runs because she has a crackerjack volunteer who commuted between Texas and Manitowoc for months of not years to rebuild her set! But he had the licenses and training to do the job. Our BZ to him, and he offered to help 20 years ago. We weren't in a position to accept that help then, but maybe we can do it someday soon.

I will reword- add some thoughts - expect more from others.

For the fact the COBIA has kept has the working and capable of transmitting IS totally incredible- FCC SHOULD allow them some transmission time. Massive Salute to Cobia for that capability being kept.

No, it exists. It was introduced in 1945 in US subs, but is based off of some tech demonstrations from 1935 Germany. In the US Navy it's called "Gertrude" for slang. There are several ways to accomplish the signal creations and reception. It's essentially a modified High Frequency Sonar set.

This may be a little ahead of its time, but did the radar have a passive search function? (To those who don't know what that is, it means the radar is not radiating but is taking radiation. Therefore, you can see if someone is searching with their radar but not give away your position by sending out radiation.)
@wfoj2 8 сағат бұрын
On the Modern ships equipment for that function is present but totally different hardware / designation. See the AN/SLQ-32 or Vietnam era the AN/WLR-1. I doubt that hardware had such capability but could be wrong.
@chrismaverick9828 6 сағат бұрын
The radar really was only ever an active search system. They introduced the APR-1 receiver in '42. It was a non-directional receiver that could tell you that a radar beam was looking your way (from somewhere), the strength/intensity and the cycle/Hz of the emission. it was often used to detect enemy radar-equipped search aircraft and could help to figure out when best to dive to avoid them, though there were tricks the enemy used like changing the output strength that could result in the aircraft getting closer than desired. Dick O'Kane of the USS Tang wrote that they used it to measure and track enemy shore-based radars that covered narrow channels. They could use it to detect US subs and then vector in anti-sub forces. The Tang successfully fooled one once on the way into the patrol zone by pretending to be a fishing boat (IIRC), but had to give her all she's got to get back out as the enemy was wary of them and tried to intercept, barely being outrun by the wily ship and her valiant crew.
