KH6/WB6FZH/QRP Pedestrian Portable Satellite Station
KH6/WB6FZH Operating QRP from Kaneohe, Oahu, Hawaii
Greg Greenwood Operates from Honolulu County BL-11 Grid
AO-27 Satellite QRP QSOs from Hawaii to "Mainland" USA
EQUIPMENT CONFIGURATION 1999

Field Notes: WB6FZH used standard polarized connectors from Radio
Shack for
all 12 equipment and accessories. The rubber covered, interlocking
2 conductor for low current, and the High Current 2 conductor Molex
for distribution and higher current equipment. The use of homebrew
branch adapters and mulitple outlet adapters makes set-up and take-down
easy. It also avoids the posiblity of reversing polarity,etc.
This antenna boom separates into 2 pieces and the antenna fits inside the
trunk of most cars. It can be disassembed and reassembled at site too.
(be sure to have extra hardware, and tools). This station can come out
of canvas tool bag and be plugged together in less than 3 minutes. The
antenna 2 pieces in about the same time. Complete antenna disassembly is
about 5 minutes. Spare alkaline or charged nicad batteries are in
zip-lock bags.
A simpler, lighter antenna is the
Arrow Antenna
that is used by many that have satellite compatible dual-band
Handi-talkies.
Consider assembling some of the power and antenna cables, adapters, etc.
for your own equipment to configure a similar portable station. You can
have quite a variety of configurations with equipment for packet, voice
even PC based SSTV,etc that can be deployed quickly into the field in
times of disaster or public service event. Radio Shack has
pre-assembled 10' & 6' BNC to BNC coaxial cables and adapters for antenna
connections.
