Like one I built when I was 13, about 64 years ago. As I recall the regeneration control actually is a sensitivity control. Listening to am, to maximize sensitivity/amplification you tweak it as close to oscillation and you can get without it actually oscillating. If it is cw (morse code) it has to oscillate to beat with the incoming signal to make it audible.
Hi Mike, yes, you're remember correctly. The radio becomes most sensitive right before it breaks into oscillation. It also becomes more selective. This was just a quick video. In reality, the fun part is having patience and tweaking the most signal possible out of some far away station.
@@michaelsimpson5417 I remember picking up a Australian short wave broadcasting station ~6 Mhz from California--just as you say, took delicate tweakage.
I watch videos of people tuning regens and it looks like they fighting a wild animal I much more enjoy a fella like you tuning with your ears as much as your hands
Awesome radio, but what really grabbed my attention was the local High school station that is always distorted, are they aware of the issue, and are they trying to rectify the problem?.
I've never contacted them. I find it hard to believe there are students qualified and licensed to operate the transmitter or make adjustments, but you never know. I'll see if I can find out.
@@michaelsimpson5417 In my neighborhood there is a local Jr. College that operates a low power F.M. radio station, "KSPC" in Claremont,CA on top of one of the dorms, there is quite an array of antennas, most of them look to be Ham HF yagi and a few verticals. I am not sure who or what the Ham antennas belong to at the college but, the FM station has their vertical antenna in the mix.
I got the music from here: www.free-stock-music.com/search.php?cat=16&mood=5&license=&bpm=&length=&keyword= Unfortunately, I can't remember what song it was.
you'd be amazed at how long them batteries....will last....the D batt's probably run the filament, and the stacked 9VDC (9 times 5 equals 45) gives the 45 volts....peanut/battery tubes, don't draw that much juice....the radio might work at 30-35 volts even....breadboard radio here....excellent...

Just ordered one. Can't wait to build it!
Very nice, it sounds great!
Made me chuckle dude, I was gonna write the same thing...
Excellent sound
Greetings from Brazil!

Very nice and good handicraft.
What is the prelude music, I love it too.

@@michaelsimpson5417 Thank you very much.
Beautiful project 👍
Good job. Greetings from Ukraine. 73!
Can I have a circuit for this tube radio receiver? ID line hs9dhk Thank you . I studied at the Radio and Television Training School. Thailand.
Hello! The schematic can be found here:
www.analogdial.com/Borden/Borden.html
Where did you get that nifty little amplifier/speaker from? It must save your ears from uncomfortable headphones!
I made it from an LM386 amplifier module. Type "LM386 amplifier module" into ebay or Google.
Does the battery holder for the filament batteries come with the kit?
Yes, it does. However, you have to make your own 45 volt battery.
Ill make mine dual power. Make a power supply off 120vac to 45 vdc and a filament 3 vdc for tube heater. This is very cool ! Thank you !
Great project 👍
Wow, hom many stations can receive in You region!!
73
Usually about five. It depends on the time of day. I'm about 20 miles north of Philadelphia, PA
AM? SW?
The Modern Radio Labs link is now broken.

Klasse !
Are you using a 3S4 or 3A4 tube?
3S4. You can use a 3A4 if you swap the wires on pins 3 and 4 on the socket. 3A4 might actually work better.
I just finished mine. I’m using a 3A4 tube. The radio works pretty good considering I live in a lousy reception area. I just subscribed. Thanks.
Nice.
This is very nice. But wouldn't it be easier to include a solid state power supply for both A and B? Batteries can be expensive.

The 9V batteries are from the dollar store and I took the "D" battery out of a flashlight.
Low noise 🎉
