If the antenna actually rides on the backpack wearers device, I'd shy away from it. If the antenna is seperately mounted, this would not apply. I heard that some of the origional police officers involved with speed trap radars did not fare too well. Apparantly, due to the size of the radar gun electronics, it was mounted in the back seat and aimed past the police officers face between the driver and passenger seats. There were cases of the side of the police officer's face becoming cancerous over time. I just heard this as a factoid/word of mouth. If the radar unit was built in the 50's/60's, this might not have been considered when designing the unit. ----- Original Message ----- From: "John Ferrell" To: Sent: Monday, August 06, 2001 6:14 PM Subject: Re: [EE]: Amateur radar? > I think it appeared on the cover of Radio & Electronics Magazine in the > 50's, maybe 60's. > No telling what it might be worth on EMBAY If you could pair it with a copy > of the magazine... > > John Ferrell > 6241 Phillippi Rd > Julian NC 27283 > Phone: (336)685-9606 > Dixie Competition Products > NSRCA 479 AMA 4190 W8CCW > "My Competition is Not My Enemy" > > > > ----- Original Message ----- > From: "Douglas Butler" > To: > Sent: Monday, August 06, 2001 12:51 PM > Subject: Re: [EE]: Amateur radar? > > > > > From: David VanHorn [mailto:dvanhorn@CEDAR.NET] > > > Sent: Monday, August 06, 2001 10:58 AM > > > To: PICLIST@MITVMA.MIT.EDU > > > Subject: Re: [EE]: Amateur radar? > > > > > > At 10:31 AM 8/6/01 -0400, Douglas Butler wrote: > > > >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.
