1) Miscellaneous non-GPS tidbits> Natural Gas/Propane... New article from Joe
Natural Gas/Propane Electric Generator AUTOMATIC startup sequencer> U-Build-it
Here's a snippet:
"I purchased a 8kw WilCo/DYNA Tri-Fuel electric start generator last year to use as an
emergency generator in my home. I wanted a remote controlled start generator, but the
price tag of about $4200 was just too much greater than the $1900 Northern Hydraulics Co.
charged for a standard electric start unit. I figured with a little time and $100 or so I could
come up with my own remote start capability. Here is how I went about it and what I came
up with...."

Jack's comments:
I decided to retrace my drive on the day SA was turned off and record the current SA
effect on the same identical topo map to get a more 'apples to apples' comparison...
So, the lower topo map in the page below has been replaced with one made today with
a G-III+ and active antenna... Also I've replaced the GM-100 base map plot with a
City Streets map plot...
