Crystal radio set 📡

Dad, Brother, and I built two of these as per instructional  plans from B̲o̲y̲s̲ ̲L̲i̲f̲e̲ magazine in 1964 ❗️

We listened to WCCO 830 (Minneapolis / St. Paul, Minnesota ) am radio using 300 Ω head sets for years with no electric power  ⚡️ and they still work almost 60 years later ❗️

‘Cat Whisker’
‘cat wisker’ radio set

You can replace the cat whisker crystal with a germanium diode for added reception clarity ❗️

How about that ❓
