- Marine radios are a personal passion of mine and in this video we look at a shipboard radio built during WW2 for the Navy. During the war, there was a massive race to create short wave radio stations and a radio infrastructure for propaganda. We’re going to talk about radio wave propagation, radio war propaganda, and also power up this old boat anchor and see what we can hear on the airwaves today.
OMG, I love this!!! I'm so glad I just stumbled upon your channel and this video; you've made my month. I fell madly and deeply in love with SW as a kid, and even though I eventually did get my amateur radio license (a goal of mine since way back then), I'd say my main radio squeeze still remains SW. My family emigrated to the US from Europe when the 'space age' was just becoming a thing, and I think even as a very young boy, listening to radio from other parts of the world, and especially Europe, somehow connected me with my forebears in ways I couldn't understand, and I eventually found myself living, studying, and working in many different countries. I feel I somehow owe all those incredible experiences to my love and fascination with SW. It was a great influence. And even now, I've been back in the States on a more permanent basis for some years, and been a professional musician my whole adult life, yet the thrill I still get when I flip the power switch and twirl a VFO (or even push a few buttons, real or virtual) is at least as much of a thrill as I get from finding the sweet spot of a guitar amp. SW certainly isn't what it used to be, but it also seems to be making a bit of a comeback. I truly look forward to more of your videos, cheers!
thanks for sharing!
Pat this is one of my favorite videos of yours!! Sooo informative & classy. Thank you for creating this and for showing the world how COOL radio is. Analog forever
Your Tec. Rad. Receiver is a Beautiful thing to see ! It's clean looks to be built like a Sherman. The Magic Eye is a pleasant surprise. I am so glad it was never exposed to the salt air because it so beautiful, inside and out . I love older Receivers although I have new rigs and rigs from the 60s and 70s . This video is a very good one !
Thanks for the time and energy you put into video.
At the opening of your programme, the signature tune was very clear, it was signature tune AIR(AKASHVANI ) that is ALL INDIA RADIO : VU7ND
HI Patrick,
I've not seen your video's before but your explanation of propagation was both visually and from a storytelling perspective was excellent. The 455kHz story was also interesting - I was wondering if the subs were listening for it although I know that for example Rugby in the UK had comms with subs worldwide on 16kHz.
What a beautiful radio - and your presentation style is captivating. Thanks - new subscriber :)
End of the World stuff - I will never forget the day that the Berlin Wall came down and both the penultimate and last transmissions of Radio Berlin are on TH-cam. As a lifelong radio enthusiast of over 45 years, I love coming across such gems as this video you posted.

Those wires twisted together are a "Gimmick" capacitor. It's used to very lightly couple the BFO to the IF. A very common technique used in communications receivers.
hey thanks. I was thinking it was something like that but didn't know that was a thing in other units.
Beat frequency oscillator? That's a metal detector sub-type.
I just discovered your channel and immediately subscribed. I'm a technician of almost identical interests as you except that I'm in the EU so my radios are German and French but the amps are the usual mix. I'm also a shortwave radio enthusiast and try to get some skip action on SSB CB. I really like your workshop! I have a few radios that definitely played Hitler, de Gaulle and Churchill's voices in their lifetime.
Great video Pat! There's a beauty and a magic to this early equipment, and to the technology of radio communication and its pioneers that I can tell you've got a lot of admiration and passion for, and it's wonderul for you to share that with us. I started following you on insstagram and TH-cam for the guitar amp content, but your amateur radio videos really spoke to me and I quickly found myself buying up old little All American Fives to fix up and listen to. It's been a lot of fun, thanks for exposing me and hopefully others to the world of radio. Next time I'm in Brooklyn or if you're ever in Texas I'll buy you a beer!
Subscribed. Amazing boat anchor! I have an BC-183D.
I love you guitar repair videos but man you did this up right! It was wonderful to learn about that era of radio and the history that surrounds it. I hope you do more videos like this along with your tube guitar amp repair. Also, the suit rocks.
Super tidy unit , You have some great old boat anchors in your collection, Liked the stories some I've never heard before. Regards and 73's Kris ZL1KJT
👍 Really enjoyed this, stirred up my interest in Radio Again 😊! Thank you…
I love the old glow bug radios .,I have the old Navy ral-6 and power supply .It weighs 69 pound and the PS weighs 40 lbs.. I still listen to it from time to time .. Loved your video..
You hooked me with this one. Guitar amps AND radio... subscribed!
TechRad made some interesting stuff. I have friends who are into the old-school maritime radio scene in coastal northern CA who absolutely adore these radios. In addition to the replacement power transformer, that one looks to have been re-wired. That orange vinyl/poly-insulated wiring looks to have been replaced, but holy cow, they did an amazing job! The electrician style numeral labels are also an indication of the later work. I'm pretty sure this radio would have had mostly fabric-insulated wire from the factory.
My late grandfather was armed-guard on the Liberty Ship SS Sara Teasdale. Those guys did some amazing stuff during the war. I presume you're familiar with the legendary story of the SS Stephen Hopkins vs. the German commerce raider Stier?
Wow . Great video, the beginning (in particular) is something you should be proud of.
They're just radios until you connect them to real lives.
Wow.
To help clarify… the local oscillator does not produce 455 KHz, but creates an rf frequency 455 KHz above or below the tuned frequency on the dial.
The 100 picofarads is a measurement of capacitance. The literature probably meant 100 microvolts as the limit.
Great video. Please do more. Love to see this old equipment!
My favorite story of musical discovery through short wave radio is how Paul Pena discovered Tuvan throat singing on short wave, taught himself the technique, and eventually traveled to Tuva to participate in their national throat singing competition!
There is a great Doco on that out there somewhere , He was a BIG man and they referred to him as Thunder throat or something like that
@@kristhompson8112Genghis Blues! A great film.
I have a National NC-173 that I haven't used since 1978. Some day I will. It has a wonderful, warm sound with its glowing tubes.
Cool video!!! ✌️✌️✌️de KB5JHT
Great video. Where in the world did you find a 600 ohm speaker? Frank, KB2VNG
Thank you for sharing !
This is so cool.
Most informative. i am a shortwave DX'er. I have recently purchased a 1950's Model Hallifcrafters. I live in an apartment and need your advice on how to set up an antenna. So far I am having trouble with reception. I DX at night. Any help you can give me will be very appreciated.
Very interesting freak. Measuring power in picofarads, not knowing that SW is using AM!
i'm glad you noticed cause I totally missed I said picofarads. I meant picowatts. when you filming your flying fast!
Maybe you might want to make some TH-cam content and find out how difficult it is to make bloopers and mistakes.
Wow, "radiated star fire". 35 yrs ago I spent a year camped in a forest in NW Oregon, a sabbatical with me, God, big foot and ET's. Kerosene lamps, propane stove, my spiritual library and an old short wave receiver. 6 D cell batteries lasted months. One hundred foot wire. At night I heard many languages and would wait till they broadcast in English with there station sign. Many nations broadcast in English news on the hour for five minutes or used to. I am now living in a small top floor apartment experimenting with horizontal loop antennas out the little window, investing in (not the best - 4,000.00 receivers!) more like 900.00 transceiver for reception only and 1,000.00 on SDR receiver. In a large city surrounded by AM and FM stations I'm learning all about filters, proper grounding, bonding. Much simpler out in the forest!!!
I'm thinking you're s licensed ham radio operator. Its just a guess talking about 11 meter and skip. I love dialing in sideband while listening to the voice from the speaker change pitch. George Lucas used vocal affect that in his movie thx 1138. I'd imagine you're at the tail end of the folks using am radio with dipole antennas(or whatever is available) and everyone younger might not understand the romantic quality of radio reception. Bonus points when the receiver has glowing tubes inside of it!! Came here for the coffee, stayed because it offered quality information that wasn't directly distilled from 3rd person/2nd hand contacts(the echo chamber of content creation). thanks
Short wave listening, or as some say dx ing was way easer because when the cold war was on and no internet you had what was called blow torches as transmiters. It took very litte money to listen around the world. sorry about the old guy talk, Good show. Best regards Jack.
One more time-it has a BFO and a VFO, the latter you could very the frequency input to SSB signals. The scale has 0 in the middle-of 1 thru 9, going up in value, on either side of the 0. Perhaps depending on if the modulation is USB or LSB?
The radio was the hro that oscilater could be detected
I'm from Royal Oak. I wish I knew what family owned it.
Didn't Germany track local oscillators to locate people using banned radio receivers during WWII?
I hate ebay stories like that. Because they never me.
It is true about 455khz trans sitting rf some English radio did that
Don't miss sundays on Worlds last chance at 9.330 when they explain how the world is flat.
