I built one when I was 9 years old. Listening to short wave was an amazing experience. Back then, there were many more interesting stations on the bands than now.
Great video and a fun production too... I have yet to experience a legendary Ocean Hopper in person, what a great radio and a nice pristine example you have. Thanks for sharing and oh, Happy Birthday 2023. 73 de AB1DQ/James
The "RNB" on the long wave band is probably an airport beacon. I can hear one that says "CHX" from the Charlevoix, Michigan airport, when I'm visiting my parents.
117L7 was a combined rectifier tube to turn AC into DC power and a power output amplifier tube for the audio to speaker 12J5 is a triode amplifier tube 12SL7 is a dual triode amplifier tube. I am going to guess that the 12J5 was the one turning RF signals into audio. The rest of the amplifiers were needed to get enough volume for a speaker.
The long wave coil could be rewound to gain the 15 to 35 MHz band, the one I began with belonged to my dad, and it didn't have either of those coils, long wave or 15 to 35 MHz.

back in the early 60s I wanted one of those in the worst way. I would drool over the Allied Electronics catalog displaying all the knight-kit products.

Вітання з Чернігова. Хороша робота. Регенератор. Ще і ламповий. Всього 3 лампи, а приймає навіть слабкі телеграфні сигнали радіоаматорів. Акуратний корпус. Ви майстер своєї справи. Можна питання?

This is one of the most bare bones radios I've ever used. The Space Spanner was a much more useful radio, and the Lafayette KT-135 was even better. The ultimate was the Knight Span Master, but the design of the tuning knobs was awful.
Its a piece of junk. My Uncle built one and put up a dipole antenna and the tuner was poor and if you put a signal generator beside it you could kind of listen to SSB. He sent it back and got a refund.
@@michaelsimpson5417 Yes, you can do that but you may annoy other nearby listeners. To make that work you would turn the regen control up until the stage actually oscillated. It would then mix its own oscillators with the SSB signal to make audio. Unfortunately, it also transmitted a little of that oscillators too.
@@kensmith5694 My fault, now I see what the reply was to. You're right, this type of regen also transmits. I've used a regen to align a tube radio by tuning it to 455 kHz. To do that, you need a modern radio with a digital display so you know the regen is on the right frequency. It's crude, but I don't have a signal generator.
I was born December 14th, 1957, so enjoyed your birthday video!
I was born in 1955! Happy birthday!

It was way cool. Worked well for a regenerative receiver.
Thanks for uploading.

Thanks, James!

You're right! I just looked into it. "RNB" comes from Millville, NJ. Thanks!!
Always good to have humor. Nice demonstration.
That's a later model Ocean Hopper. The original used octal tubes, a 117L7M7GT, and a 12J5 or a 12SL7.
I dated it to around 1959. (link under the video)
117L7 was a combined rectifier tube to turn AC into DC power and a power output amplifier tube for the audio to speaker
12J5 is a triode amplifier tube
12SL7 is a dual triode amplifier tube.
I am going to guess that the 12J5 was the one turning RF signals into audio.
The rest of the amplifiers were needed to get enough volume for a speaker.
The long wave coil could be rewound to gain the 15 to 35 MHz band, the one I began with belonged to my dad, and it didn't have either of those coils, long wave or 15 to 35 MHz.
Well done video, and Happy Birthday!
Classic. Good job. This reminds me of one of those old Robert Benchley shorts.
I built one in the 60s it worked well and always wished i would have kept it.

Awesome!
Que top muito chique mesmo goste muito parabéns

RNB = Radio Navigation Beacon (for aircraft) assigned to Millville, NJ and operating at 363 KHz
Thank you! Mystery solved. I'm in PA near Philadelphia, so not surprising I can hear it.
VERY KOOL !
THANKS 😊
good job🎉😊
The first radio I ever built!
Door sounds like inner sanctum..hihi

The Ocean Hopper runs on 110V AC. No batteries.
could have been a bit more to the point but hey its your humor and your video
True, it didn't need the bit about the train, but I tried to make it entertaining for people who aren't hard core Ocean Hopper fans.
Sorry. I don't have notifications turned on. I completely forgot about your birthday. Congratulations.
Thank you!
Good luck friend, de UR5RBZ, 73!
All those knobs to tweak and only 2 hands.
So me interessa circuito Brasileiro
I as well say Chas-sis

I think some companies in the US are making vacuum tubes, but they are for high end audio amplifiers.
Did you open a portal and let out some demons? And were they makin' the cheesy commentary?🤔
if radio had a decent audio amplifier and a real tuning vernier and DC supply it be much better.

Maybe he got a bad part. You can listen to SSB on a regen if you tune it carefully. Also, it wasn't made for a dipole.
@@michaelsimpson5417 Yes, you can do that but you may annoy other nearby listeners. To make that work you would turn the regen control up until the stage actually oscillated. It would then mix its own oscillators with the SSB signal to make audio. Unfortunately, it also transmitted a little of that oscillators too.
@@kensmith5694 Ken, which part does this refer to?
@@michaelsimpson5417 I should have been clearer. It was about doing SSB.

mexico says there poor... yet they have like 20 SW stations lol ...
