    A friend came by my shop and dropped off this radio as a gift. I haven’t done any research yet, it looks like it came from a ship circa World War II. Of course I immediately had to open it up and see what was inside. The lead dress is pretty incredible. These guys weren’t messing around. There are definitely quite a few parts I could use to build a guitar amplifier (PT especially) but I’m not sure it would be worth chopping up such an amazing piece of equipment.

    Hazeltine doesn't exist anymore but definitely made EXCELLENT electronics when it did.

    Learn to route, bundle & tie cables like they did and you'll never have noise problems.


    Ex-USN here.

    That bears a passing resemblance to a ship-to-shore radio that occupied a lonely corner on the island of my first carrier. Tube powered, no one was sure if it still worked, but it stayed around as kind of a "last resort" thing in case everything else quit working.

    Edit: I'd have to check my history, but I think "Navy Department" puts it at Korean War or earlier. When the Dept of Defense was created, it changed the Navy name to "Dept of the Navy." The last "Navy Department" piece of gear I remember seeing was a 50lb CO2 bottle with an initial date stamp of 1944.

    I saw something recently about Hedy Lamarr's frequecy-skip patent first being used in sonobouy comms, she never got a nickel.

    Bundling and lacing the wiring was a fine art in military electronics. A thing of beauty that had a functional purpose.

    Personally, I don't think that I would do any modifications to it. OCT-3 was post WWII, but before Korea. In essence (and simplest explanation), it was part of the beginning of digital communications. Using an FSK transmitter, an operator could send CW with a "mark" on one frequency and a "space" on another. The frequency shift monitor was the receiver. Depending on the timing and when the "mark" and "space" occurred on their respective frequencies, the CW message could be reassembled. 1's and 0's.

    Our EC-121 "Warning Star" patrol planes used Hazeltine IFF and SIFF boxes, that's how I knew them.

    What do you think I should do with this? The guy who gave it to me bought it from an electronics recycling center. He was about to gut it and use the front control panel as a prop in an escape room but thought twice about it and decided to give it to me because I’m the only one he knows who builds tube amps. I have enough respect for the quality of this piece to let it live on, (may not be able to resist pulling the guitar related tubes,) but I don’t need a 75lb paper weight. What do you think the best thing to do with this is?

    On a side note, I didn’t notice a single electrolytic capacitor in this. On initial peek, the big sardine cans between the transformer and choke appear to be the power filter caps. I’m guessing that this unit would power up as-is without needing any servicing.

    It appears in excellent condition. Do you have a military museum that you could "loan" it to?

    Those pics were of the USS Bowfin in Hawaii (Pearl Harbor to be exact).

    I was not a submariner as my Navy father (USS Kearsarge CVS-33) suggested it was not a good idea for a 6'3" dude to be camping in a hollow tube with 4 foot doors.

    Naval aviation was my plan, however plans change.

    Thanks for your service!!

    Here's my fully functional "boat anchor" tube Ham HF receiver, a Hammarlund HQ One Eighty. Somehow listening to shortwave stations with this just "feels" better. 73 de K9OJ.

    Hammarlund had an excellent reputation among amateur-radio ticket holders.
