That's cool! I've done many of those experiments. In fact, I built a HERF
gun (a sort of microwave ray gun) out of microwave oven parts, some scrap
metal and duct tape. It worked really well. I could fire a beam of
microwaves that could fry a remote control, make a CD go up in sparks and
light a flourescent light bulb from 7 feet away without wires. Just for the
hell of it I put my hand in the beam and it felt warm but suddenly I felt a
burning pain on the side of my middle finger where a large blood vessel runs
and pulled my hand out of the beam. I won't do that again. :-S
I noticed when filming it that everytime I placed something metal into the
beam, the camera would go fuzzy from the backscattered microwaves. This is
what gave me the idea of sending a microwave beam into the ground and
checking for backscattering to find meteorites. If you were to use a short
wavelength and send it down by means of a bunch of waveguides all lying
parrallel to eachother in a big grid and pointing downwards, you'd have a
wide but strait beam and the whole apparatus could be put on wheels and
pulled behind a vehicle. If each waveguide had a detector in it to detect
the backscattering then you could figure out how big the object was by the
number of waveguides that detect backscattering.
I just got my letter of acceptance from the college I applied to and it's
for an electronics engineering course so maybe when I'm done it I can build
this bad boy!!
Cheers all
Graham

11:21:13 -0400 Hi Guys, I just know that the acres of farm fields I
have access to has meteorites just waiting for a meteorite
detector/detectress, and an able-bodied shoveler/shoveltress and I would
love to put together plans to be that such person someday. I'm not sure
I'm ever going to be a 10' hole-digger but I can aspire to 3' for a nice
prize found in my very own strewnfield (yes, I'll find one). After I find
a strewnfield then I'll consider 10' but only with digging equipment.
Does Whites still put out such a detector? (I could look on their website
but don't know exactly what to look for.) Does your neighbor get used
model$? How about display model$? We have to consider light weight if that
is a possiblity. I know I'm getting way ahead of myself but I want to be
ready! As it happens, Arizona Keith is the same person I was discussing
GPR with and have been leaving him to recuperate quietly. I have trouble
recuperating quietly...can you tell? No jokes please ;) (...unless
they're really funny) No snow here in SE Michigan (right now), Maria

Microwave my meteorites? Date: Mon, 11 Apr 2005 08:52:03 -0600 Dear
Maria; My neighbor is a white's detector salesman and a few years back he
went to Odessa and hunted the field briefly in the 99 degree heat. His
guide was none other than James Williams, Rocks from Space page 136.
Ron used the top of the line two piece deep penetrating unit White's
had out at the time. The plan was to search 3-10 feet deep for items that
the regular detector crowd had missed. Between the heat and the pipelines
in the area The deep seeking unit did not produce any meteorites in the
four hours of searching. Ron did find some real nice odessa's in Mr.
Williams collection though. Ron felt with a better weather condition that
he would have done much better but noted that Odessa is an old oil boom
town and there is a great deal of metal around. Digging 10 foot holes for
pipe thread protectors would not be productive so maybe the area would
have to be a bit more primitive to have the deep penetrating radar be
more successful. No snow in my part of the rockies, Dave F

has been using GPR for many years and has used it to try and locate

off his oats for a while but I'm sure he'd be happy to post some info
and stories to the list. Best, John Gwilliam At 05:33
