Antenna
Masts
Here is an idea the
OH-5
team
uses. In looking
for a
good
portable extension mast that would not take up much
room, we found a
great
fit. We found that Lowes builders supply had magnesium
extension
handles
for trowling and painting. These pieces were found in
two sizes, 1 inch
by 5 foot and 1.5 inch by 6 foot. They screw together
regardless of
size,
are sturdy, and extend to as many pieces as you wish
to screw together.
We use two 6 footers and one 5 footer screwed together
to make a nice
17
foot antenna mast. Cost is under $20 a section.

circuit time
out problems
Some
cellular data
systems
fail
during peak use
times
due
to built in time out of the data system should no
data be transfered
over
a period of time. Try seting up a ping to a known
good IP address and
use
the -t switch to activate repetitive pings.
This should
help
keep the cellular circuit alive for your data
use. Use the
following format:
ping www.url.com -t

NTIA
Standards
The NTIA has
upgraded
specifications
for all radios
used
on government bands. Recently FEMA has mandated
all participants
in SHARES on FEMA frequencies will comply with NTIA
specifications.
Below you will find resources to help with understanding
the new
requirements
and in determining whether your equipment meets the new
NTIA standards.

Long
Distance Phone Calls
NDMS allows $3 per day for
personal
calls. At standard
long
distance and calling card rates, you won't get much time
on the line at
that rate. However, there are companies that allow
prepaid long
distance
calling at 2.9 cents a minute. That means for $3 a day
you would get
over
an hour and a half calling time! Try One
Suite, one of these companies. You also get online
tracking of
all of your calls. The system works just like a calling
card, but you
can
recharge the card online. Found this one courtesy of
Clark Howard.

West Mountain Radio has
developed
several nice DC power
