In another thread, Roger Chaffin said SAR mirror? Try a dead CD. Or a stove wind or radiation shield. Or a camera flash.
I’ve wondered about CDs for that but haven’t tested one, have you Roger?
Anyone else have first hand test experience with other multi-use items as signal mirrors?
My idea of a test is to catch the eye of someone who is looking for you from a good distance (>1km maybe?) when they don’t know your exact location. Even better, attract the attention of someone who is not looking for you (somewhat harder to arrange)
