    What became of the models?

     

    One comment in the FB thread:

     

    "When you drive by the lab on the way to Cabrillo National Monument there are a number of these models still sitting in the yard outside the lab.  Many years ago the Maritime Museum borrowed one for a model exhibit, it was an aircraft carrier and as I recall it was over 20 feet long!"

     

    And another

  2. Iowa class model at the antenna range, Pt Loma, Navy Electronics Laboratory. The model is made of wood and plated in brass. The model is 18'6" long, 27.5" wide and weighs 550 pounds.

     

    1949 Press Release - 

       In planning communications systems for ships at sea, Navy scientists seek to design shipboard antennas capable of sending out substantially the same amount of energy on all directions.

     

       This problem is attacked at the US Navy Electronics Laboratory, San Diego, California, by the use of miniature ships whose topside structures are precisely scaled counterparts of full-sized naval vessels. These models make it possible to conduct investigations of shipboard antenna directivity under controlled conditions on land. Scale factors of 1/12, 1/24, and 1/48 are used in the studies and are applied both to the construction of the miniature ships and to the radio wavelengths most commonly encountered in shipboard communications.

     

       In practice, the scale model is mounted on a turntable and rotated over a mesh of hardware cloth while it antennas are supplied with energy at the correct radio frequency. The hardware cloth simulates the conductivity of the ocean at regular communication frequencies. The radiated energy is received and its intensity measures at special stations on the rim of the "ocean". These measurements give radiation characteristics of the small antenna, and by extension, the performance of a full size antenna aboard a full size ship at communication frequencies.

     

      Each ship is electronically complete down to the waterline. Each has operational antennas for transmitting and receiving radio signals at varying frequencies. Because metallic ship environments distort and alter the radiations from antennas, and obstructions topside provide added interference, antenna efficiency usually depends upon the placement, design, and number of the antennas.

     

       The Laboratory tests the efficiency of a particular antenna design by sending and receiving signals in all frequencies while the ship model turns through the 360° of azimuth on a 22-foot turntable in the center of a 160-foot lead and wire-coated field. The coating provides environmental conditions roughly approximating those of the ocean.

     

       An actual ship could make only a limited number of turns in a day, with consequent loss of operational time, manpower tieup, and interruption of other training. Moreover, changeable weather conditions would prohibit testing under controlled physical conditions, as is possible on a controlled range.

     

       A further great advantage of the range is the design and test of communications systems as an aid to ship preliminary design. Technically, the artificial ocean is a conducting ground plane, and the experiments measure on the ship models vertically polarized components of horizontal-plane patterns in the 96 to 1440 megacycle range, simulating the 2- to 30-megacycle band.

     

       A two-axis free space mount, available for measurement of zenith coverage patterns in the 1000 to 3000-megacycle range, can accommodate scale models (usually 1/4 scale) of ship masts and superstructures. Use of a wire mesh ground plane of about 40,000 square feet with five 90-foot wood poles permits realistic full-scale tests of simulated ship antenna systems, and an additional 120-by-150 wire mesh ground plane has a rotating antenna mount for development and test of specific antennas for ship and shore applications.

     

       Ship communication mock-up facilities in the antenna range building make possible the study and development of complete ship radio communication systems under conditions simulating those aboard ship. Improvements now under way at the ship model range will permit absolute measurement of antenna patterns and extension of measurement to evaluation angles above the horizon.

     

       Nearby microwave facilities include a range for rapid and accurate determination and recording of the free space radiation patterns, impedance, and gain characteristics of microwave antennas in the frequency range from 1000 to 10,000 megacycles.

     

       NEL engineers must study as many as 3,000 to 5,000 radiation patterns for each new ship design. To lighten their workload the antenna range specialists recently devised a Pattern Analyzer Computer (analog to digital) equipment which is used to determine values required from the antenna patterns by an IBM computing machine.

     

    The history of US Navy electronic technology at Pt. Loma

     

    The history of electronic technology began on Pt. Loma a long time before the establishment of the laboratory here in 1940. On May 12, 1906, a chief petty officer and two sailors drove a horse-drawn wagon to the downtown pier and loaded up a massive 5-kw. transmitter/receiver, the state-of-the-art in communications. This was the new age of "wireless radiotelegraphy," which the Navy would eventually shorten simply to "radio." Many hours later, in the little station house they’d set up on top of the hill, the equipment had been installed. The chief sat down and tapped out a hopeful message to the Mare Island Naval Radio Station. He was hopeful, because the distance record for Navy wireless communication at the time was about 125 miles, and Mare Island was 500 miles away. He was stunned by an immediate reply, and in celebration commissioned the facility as Navy Radio Station Pt. Loma.

     

    On June 1, 1940, Secretary of the Navy Frank Knox established the Navy's first laboratory on the West Coast, the U.S. Navy Radio and Sound Laboratory. Its mission was to perform research and development in communications and radio propagation. In 1943, a second West Coast laboratory was established in the high desert at Inyokern, Calif., the Naval Ordnance Test Station (NOTS), charged with improving naval weapons systems, particularly those dropped from aircraft. NOTS became the Naval Undersea Warfare Center, the Naval Undersea Research and Development Center, and the Naval Undersea Center (NUC).

     

    The naming history and name changes across seven decades is convoluted, so try to follow along. (see the SSC San Diego Org History flow chart in photos for more subornate commands involved and integrated along the way).

  3. I got a text from my eldest brother,  Michael,  that he was unable to wake his wife, Joan,  this morning, and so was in the  ER with her.  She's suffered from Alzheimers for some time now. 

     

    So, if you could spare a prayer or two for them it would be much appreciated. 

    ====================================================================================================================================

    UPDATE 1 (I expect there to be more, they will appear in this post when they happen)

     

    Just got another text - he's "frazzled" but Joan is awake, back to her "normal" but hasn't tried walking yet.

     

    The prayers are much appreciated.  Keep 'em coming, please.
    ≈===========================

    UPDATE 2

     

    So far tests are all normal.   Kept her overnight for observation and more testing on Sunday. 

     

    =================================

     

    I just got this:

     


    "This is a copy and
    textYesterday morning at 7:15 I tried to wake Joan up for her morning pill, she was totally non-responsive. I had a very difficult time detecting any signs of life. She was like a rag doll. I held her hand above her face and dropped it, like our son told me. It's a test of how far out a person is. The further out, the more likely a person will overcome the bodies natural defenses and slap themselves. She slapped herself in the face. She was like that until almost 10am. The Providence paramedics did the same test. Right now she is having an eg of the brain.
    The Nurse said She will not be discharged today.
    Joan is tired and confused. But does walk to the bathroom sort of by herself.
    Yesterday morning I thought I was going to tell people she had
    died,"

     

     

    HOLY CARP!  I can't imagine how scary that was. 

     

    At least she is walking. 

     

    ===================================================================================================================================

     

    Good News! I just got a phone call from Mike. Joan seems to be out of the woods. Some tests showed that she has herpes...which led to a lot of itching and fatigue.  They treated that, took her off some meds.  She seems stornger, not as tired.  Was able to walk around some.  It might change tomorrow, but Mike is savoring the improvement NOW.  

    Of course, the Alzheimeres is still there, that is never going to really get better, but possibly with that herpes now under control Joan will have more energy, which will help with some of the Alzheimers symptoms.

    Thanks for all the prayers.  

    Powerful thing, prayer.

    Now I won't be dreading every "DING" of message notification on my phone.

    Gotta say, when I saw his name on the Caller ID I thought, "Oh, hell......" and got ready for The Bad News. One of the few times I've been so happy to have guessed wrong.

  4. Discover Explosion Museum

    Priddy’s Hard was where all Royal Navy warships, including HMS Victory, came to load up their guns and ammunition up until the Falklands War in 1982. Safely outside the range of Portsmouth Dockyard, Priddy’s Hard stored munitions too dangerous to be kept at the main site and was home to a multitude of different personnel and professions.  

    This historic location, complete with original 1771 ‘powder keg’, has been completely reimagined as a testimonial to naval firepower. From exhilarating exhibitions, immersive recreations, and authentic armaments from across the centuries Explosion Museum of Naval Firepower is guaranteed to put a bang in your day.

    Imagine having the ability to go back in time and convincing people, people in power that this is true. Imagine how far we would be today in space technology and travel due to the scary perception that Mars is inhabited by robots. Sometimes fear can be a great motivator. 

     

     

    We all know that's not true!  The inhabitants of Mars look like

  6. "of sorts"

     

    Seems some people missed those qualifying words.   

     

    I see infomercials as con jobs "of sorts."  Play up strengths, downplay,  or ignore, weaknesses.   Same for politicians. 

     

    Just my view of it.

     

    Not unlike how so many people here view all Californians.

    LOL!   Well, that's my bad.   For some reason, I misunderstood the line to mean 11.5mm.   Silly me.  :)

     

     

    For some reason the copy and paste took out the space between the 11 and the. 50 (just like it moved the space just now!)

  8. I showed that first short video to my wife and she said, "What am I looking at?" so I  told her, "A right angle,  gearless drive. "

     

    "No.  What's it do?"

     

    "It takes power from this direction (hand motions),  and makes it go this direction (more hand motions). "

     

    (in somewhat irked tones)"What  does it DO?"

     

    "You have a shop with a belt drive going this way, but you need a driven belt going at right angles to that to drive something else."
