Author: C. Sullivan Date: To: listserv Subject: [Az-Geocaching] Amateur Beacon / GeoCache..
It's about to happen: a GeoCache that can be found not only by GPS, but by
radio direction-finding.
I recently constructed a small QRP 2 meter CW beacon inside the bottom of
a quart-size paint can. It has a small solar panel and two AA NiCd cells
for power. It is capable of transmitting a 100-character message every
five minutes. My initial tests show it has about a 45mW output.. but
beefing that up to around 150mW should be trivial (one good transistor can
do wonders).
I've given it a lot of thought, and I've decided that I want this little
"rabbit" to be my first GeoCache. The only problem is, I can't think of a
really good place to put it. So, here's my challenge.
If somebody out there who is a ham (or other radio hobbyist) can find me a
good mountaintop site to hide a GeoCache, preferably somewhere where a
100mW signal can be heard for enough of a distance to be
challenging / interesting to RDF enthusiasts, and also an interesting
destination for the GPS-equipped.
