In this video I had the privilege of interviewing Mr K E Edwards, the author of Two books on Crystal Radios. In this video he shows some of the radios he built over 40 years ago. Most of these radios are designed for the AM broadcast band, but a couple of them are designed for short wave, long wave, and believe it or not even the FM broadcast band. For those who may be interested in ordering any of his books, you can find them on these links. hopeandallen.com/

It is good to see that folks still make Crystal sets. I made my first in the 1950's that planted the seed. I am now retired after a career in the Electronics industry. Just a couple of weeks ago I came across a box in my house loft containing all the vintage Ebonite parts of a Chrystal set except the detector so I might sit down and construct one from the parts.

I met this old guy when I was in elementary school. He build fox hole radios in his garage. He helped spark my interest in building radios. I built heatkits when I was in high school. That evolved into my getting my ham license and many enjoyable hours on the air. Nice video, it took me back to those old days in my neighbors garage

The "foxhole" radio at about 5:46 is just the detector. The actual radio needs a coil. Generally there is also a "wiper" to make the coil adjustable. I made one in the 4th grade or so (early 1960's). I think I used the school's steam heat radiator pipe for the ground. It worked. Crystal headphones have the best output. Cheap crystal headphones were easy to find in the 1960's.

I was doing this stuff beginning around age 10 or 12. One tube radios using a 1T4 quickly followed with an A.C. Gilbert set. Then a two tuber Knight Kit. This is all still valid education for both adults and kids. What is a mobile phone before it's anything else? Answer: It's a two way radio. Without that most of the other capabilities are impossible.

I built a crystal radio in the late 70's just for fun and the first thing I heard when I tried it out was E.G. Marshals voice the program was The CBS Radio Mystery Theater. It couldn't have been more perfect timing, it was as if the radio was picking up broadcasts from the past. At the time I was stunned because until then I didn't know the program existed.

Thanks posting! I have the first book and built the sets described. I loved the shortwave crystal set featured in the book, was simple yet sensitive. I am looking forward to get the second edition.
