Lanny —
Where did you hear that the DOD may turn S/A off? I was thinking that the GPS
manufacturers could get together and force the DOD to turn off S/A under the
freedom of information act unless they could prove a big military advantage of
15 meter as opposed to 100 m accuracy.
Just out of curiosity, how many sats does your Scout usually lock on to in your
neck of the woods? You are in WA – right? Here in central CA I get six 99% of
the time in flat terrain. I have noticed that your body can block or weaken the
GPS signal. If you hold the unit close to your body and turn around, you will
see gain or loss of signal strength on one or more sats. If you put your hand
over the antenna, you usually lose them all. One implication of this is when
using the unit on the side of a hill, you should probably stand with your back
to the hill.
