Hello, I rember a unit like this for sale a few years ago from a surplus place. It was a point to point (line of site) voice link used as a pair one at = each end. >>> dbutler@IMETRIX.COM 08/07/01 12:01AM >>> About a year ago I pulled a radar-thingy out of the dump. It is called a "Whistler Radar" model WR-108 US Patent# 3735402. It is small suitcase sized and hangs on a shoulder strap. Most of the volume is occupied by a parabolic reflector antenna. It has jacks for 12V and headphones, and has one knob and an analog meter labeled 0 to 1 nautical mile. Does anyone know what I have got? It is a little corroded but could probably be gotten working, if I knew what it is supposed to do. The company doesn't seem to exist anymore and I haven't had time to track down the patent number.
