I had a crystal radio receiver when I was a child, and this brings back some memories. Incidentally, I don't use much of the modern lead-free solders as they are rubbish.

I've build many crystal radios and there's only one type that uses (two) variable capacitors that works well. The simple wiper style is what I recommend for most folks.

Looks like you have a unit from the 1920's or so! A friend of mine builds "Replicas" of old sets from plans published way back then! It's very difficult to get hold of an original "High Impedence" type of headphones. So, sadly most of us have to resort to those cheap, low quality earphones made in china. Some seem to work okay, while others don't work at all. GOOD LUCK.

Thanks for info, good times building these radios.

Good day to you. Why would you buy a kit? These crystal radios are *SO* easy and cheap to make. Success depends on a long antenna 100’ plus (as high above the ground as possible, horizontal and properly insulated) and an *EXCELLENT* ground connection. Make these adjustments and you’ll pull in stations from 100s of miles away. Good luck to you!

Thanks for showing this. I'm playing with a transmitter from parts at the moment. Notice how it didn't require power. In a sense they were less stupid back then. That's why it's a good idea to look into. I found a mono amp board at the size of 3x3x1 cm more or less in China (eBay) and it's quite useful as I power it from USB/5 Volts. It gives a good punch for mono setups for simple stuff. I didn't predict that I would use a little amp so much. It goes from one place to another all the time.

Great job!! It came out nice 👍

I soldered for my work for over 20years , rosin cored lead solder, either try tip a bit hotter or perhaps a heavier tip, have heard the lead free soldervisnt as friendly. Im aboutvto go back to basics and build onr from scrap and crap,, im qquite excited 🤔

Great job, and I learnt what 'tinning' is .. Thank you.

109, 110, Hey Mike, wanna go get lunch with me? No thanks, i already ate. Um... 8, 9... 😂😂😂

thats a nice stained glass panel

Good job 👍

Great :)

A beautiful century-old device. That crystal is galena. Pyrite (ferrous disulfide) can also be used, which is also a very good detector. Galena can be made at home. To the kit - a very unsuitable handset. It is necessary to use a high ohm handset (2-4k). Then there are the radio stations themselves, which are mostly FM. The crystal received long and medium AM waves well. Very short AM waves could no longer be received well, just as it is not possible to receive FM well around and over 100MHz, except that FM is a different way of receiving and FM transmits with a fractional power compared to AM. Theoretically, nothing can be heard through the crystal in this century. If so, then a very close AM CB source, or an AM band reserved for emergency broadcasts. In most cases, it is no longer possible to receive an AM crystal.

You made a good work assembling the kit. Perhaps it is one of the non-performers. That design in particular has many flaws.

What's the diameter of card board tubing? It seems 2" to me. You are I guess using 28 SWG, if I'm not wrong?

Thanks... You Soo . Much sir . For is .video. ....Graet .. ...sir

By sound do you mean radio stations just wanna know if you managed to pickup any stations

👍👍👍👍👍

This is the first video I've saw like this an the guy talking doesn't sound like his on the radio 🤣

what is the name of yours and what makes did your friends get,

We call them alligator clips in the us !=8)

That paper tube is not really strong enough. Too easily damaged.
