In the mail call episode you could not only hear stations coming in clearly when R. Some how even though I was disappointed I was not surprised the thing didn't work. It wasn't until fairly recently that I discovered the blade also had to be treated a certain way in order for it to work and even then it takes some luck. I had already built crystal radios successfully in the past but I never managed to make the foxhole radio work. I recall buying my first pack of razor blades at the age of about 10 as a result of me deciding to try and build this foxhole radio. I remember years back on the show "Mail Call" they presented a foxhole radio of the razor blade type as something very easy to make. I have also messed with some of these, again fun.But as with the blue blade, I moved on to more stable types: Galena, diodes or tubes.įoxholes can be fun, but as I have posted in the past, not so good as a first radio project Of course the only early detectors that lasted until the broadcast days were Silicon, Pyrite or Galena cat’s whiskers. Most faded from use quite early on as much better types came along.Again, the blade was used only out of desperation 30 or 40 years after most in this category fell from use. There are LOTS of “ exotic “ detectors (razor blades, dissimilar metal, flames, carbon and a number of other bizarre types from the early days of wireless). And if the GI’s had ANY other choice of detector, they would have used it and saved the blades for shaving. Mine was extremely hard to get working and seemed to need a BIG antenna and good ground to motivate it into working.įun, not too practical though. NO pencil ( which I have tried and works “ better “). Mine was built with only a rock and a knife and uses a blue blade and “ C Ration†Wrigley’s Spearmint as coil “ dope “. Foxholes can be fun, but as I have posted in the past, not so good as a first radio project ( unless you suggest using a diode first, something I have never seen ANY of the plans mention).
