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.

Excellent work ! You are a genious !
Thank you Klaus. Ohhh I wish I was hahaha. 73, YO6DXE.
Very neat build, nice base plate and good components!!!
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.

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.
Very nice job!
Thank you my friend. I have one more to build when I have some more time. Apparently that one should perform even better. 73, YO6DXE.
@@dxexplorer I will be looking forward to seeing what you do with it.
@@radioguy19510 Fingers crossed they turn out as I imagine them. Usually things never go as planned )).
was excited to see this video. HNY!!! My next project after finishing the sputnik
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.
Sound good. 👌🏻 well done buddy! 👍🏻
Thank you so much. I am curious if the other one also a classic design performs better. I will build that one as well when I have a little time so I can compare them ))). I had them on the list for a very long time )). 73, YO6DXE.
@@dxexplorer that made me curious also.
I think the other one is called Miller design or something like that. I must search through some of my notes.
Hey, Ciprian! Congrats on a Happy New Year 2024 and on your first video released in it! We'll be watching for another curious review from you. 73 de EX0QKT Archie
Thank you so much for watching and Happy New Year. I am trying to catch up with the videos as I was too busy with work and had no time to make any 😁. 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!
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.
@@dxexplorer yeah free time is most important thing in every project 😁. okay then good luck and 73!
@4L1LAT Thank you my friend. Ohh yes so true. Have an amazing rest of the week. 73
Nice build...if you know anyone with an actual CR-1, it would be interesting to compare the performance of the 2.
Thank you so much. Ohhh yes that would be fantastic. I have no clue right now if I am any closer to the original kit. 73, YO6DXE.
You are welcome 🎉
Thank you one more time Hendrik. Love it and I am listening to it as we speak through the computer speakers... very loud 😅😅. 73, YO6DXE.

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.
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
@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.
🎉Happy new year!!🎉 Please make a new improved CW transceiver
Hi Edwin. I have something in mind for a long time.. but right now I am still a little busy with work. Probably at the end of next month I may have something... if not in March the latest. I want to make a lot of tests before to make sure my ideas work ))). 73, YO6DXE.
Very nice work.... keep up the good work, very inspiring and useful information here. 73 de AB1DQ / James
Thank you so much James... and thank you for watching. I can't wait to try a few more classic designs and maybe even stick my nose into trying to mix some of them and make a better one )). 73, YO6DXE.
Podria indicarme los colores del condensador C3 y C4, ya que no consigo informacion en goole, o que colores contiene.
Aquí tenéis un enlace con mucha información sobre el código de colores de los condensadores.

Hi my dear friend....🎉😂
Hello hello and thank you for watching. 😁 73, YO6DXE.
Thank you so much 73 bye bye
@Rajagiri-2017 have a fantastic day buddy.
Excellent one if I use 1N34A or 1N6O it will work?
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.
Back in the 80's I used the classic 'Mullard OA81' germanium diode (glass or black coloured type)... you can still get them ... might cost more than than the newer ones ...
@@krellft Good to know that 😁😁. I will try to search some and get my hands on one so I can compare them a little as I never paid attention to this detail in the past when I was a kid. I was happy I have one diode to use that worked haha. 73, YO6DXE.
Văd că nu ați conectat nici antena nici ground, funcționează?
Salut Marian. Ehh in poza nu, dar in clip da 😁. Doar ca nu aveam antena aia traditionala si impamantare cum trebuie. Am folosit practic antena de la statia radio, iar in loc de impamantare am legat tresa de la cablul coaxial. Si totusi merge si asa. Ma gandesc totusi ca daca as folosi o antena cum trebuie si o priza de pamant bine facuta, receptia ar fi mult mai ok. 73, YO6DXE

Aveți o schemă? Mulțumesc!😊
Am pus in video schema originala dupa care m-am luat, dar undeva in weekend o sa pun si articolul pe blog cu mult mai multe detalii. O trebuit sa tai mult din video la final cand ascultam ca era multa muzica pe posturi si na... copyright ))). 73, YO6DXE.
Mulțumesc mult!
@cioboatamarian Cu mare drag. Saptamana ce vine sau peste doua saptamani o sa mai incerc unul care in teorie se spune ca este si mai bun ca asta... tot un model clasic.
Hello, can I send you a ferrite rod with a length of 200мм and a diameter 8мм, может вам пригодится для этой поделки, просто я не знаю есть ли он у Вас, их сейчас сложно найти😅
Hahaha... thank you. I have one but is like 10cm long. You should keep it... it may come in handy. I have these ferite bars since 20 years ago and I only ended up using them today ))). Usually I recover them from old junk that people get rid of.
