After receiving the Heathkit CR-1 Crystal Radio faceplate from my friend Hendrik, I decided to build a replica of this classic 1958 crystal set. It tunes from around 530kHz up to 1200Hz.

well done mate.. classic xtal set...look forward to see what you get up to next.

Thank you so much 😁🙏. I have one more classic set I want to try... apparently that one was even better than this one. Let's see when I have some free time for that. 73, YO6DXE.

Thank you David. I think with the proper antenna it could receive a few more stations. Right now I only get four or five stations ( in the evening )... in the day time only two Romanian stations. 73, YO6DXE.

@@dxexplorer Excelente trabajo, podria decirme donde puedo conseguir los condensadores de colores ya que ne mi pais no existen esos tipos de condensadores.

@RanchoIxmucane Muchas gracias amigo. Tengo el mismo problema con los condensadores variables. Para mí también es difícil de encontrar. Todavía hay pequeñas empresas que los fabrican, especialmente en Estados Unidos, pero son bastante caros. Los que usé en el video son nuevos en su caja, un regalo de un amigo. Pero estos dos que usé fueron hechos en 1973.

For me it was hard to find the variable capacitors to match them. Love it... works like a charm and I am sure with a simple long wire and a proper ground connection it will work even better. 73, YO6DXE.

It turned out great with very simple design. Now i get why it took you some time to make coil😅. you can leave that ceramic capacitors there it wont change frequency that easy. diode I think it was Soviet d9 diode if you get d18 it will work much better than it is. that's all i wanted to say. Good luck and 73!

@dxexplorer 5 ай бұрын

Thank you so much. I have a couple of diodes that I want to test and see "who is the star" 😅. The coil... ohh yes hahaha... a nightmare to make but it turned out great and I am happy. I love it so far. The capacitors... ohh yes they seem to be just fine so they will stay as they are. I have a few more crystal sets designs I want to try just for fun and to bring back memories of the past. I just need a bit more free time. 73 my friend, YO6DXE.

@roberthorseman7432 4 ай бұрын

Maybe you could fix some m3 type nylon bolts to the ferrite cores with nuts glued to the former so you could adjust the inductances of the coils.

@dxexplorer 4 ай бұрын

Ohh yes I wanted to do that. Sadly I was in a rush so I can finish filming the video... but I think I will remake the coil and then I will also fix the nylon bolts too. It would make my life a lot easier ))). 73, YO6DXE. P.S. I think the original ones were made the same way.

I believe they were also I wonder if wave wound coils would make a difference.@@dxexplorer

@dxexplorer 4 ай бұрын

@roberthorseman7432 That I don't know. I kept trying to find some high resolution photos of the original ones... but I think what I found so far they seem to be replicas so I can't tell for sure. But I think as long as the coil has a good Q factor and the proper inductance as calculated for the desired frequency... it should be OK. At least this is what I did with the one in the video as I recalculated the inductance to fit the value of the variable capacitors I had... trying to cover the same frequency the original receiver covered.

It should work yes. I tried three random germanium diodes as I don't know exactly what type I have and all three of them worked. I think the one I use now is 1N43 or something like that.
