Throwback Thursday: I drew this cartoon years ago for a chapter on safety in “First Steps in Radio” by the late Doug DeMaw, W1FB, published by the ARRL. It makes a really good point: Some of our equipment — particularly power supplies — can kill you if you’re not careful.
Always practice safety first — and NEVER work on high-voltage equipment when you’re not fully alert. If you were tired before, you’ll end up going to sleep a lot sooner than you’d planned.
