Just one more point:

Your GPS map datum should be set to WGS84 (which should be the default), and 
if the unit is equipped with it, WAAS should be enabled. This will ensure 
you will get the lowest possible accuracy reading.  This accuracy figure, 
along with the lat/lon coordinates, must be pictured in your video or camera 
footage along with your station on the boundary.

I use the Garmin etrex Legend HCx and I have never had any issues with 
finding grid boundaries.  Just make sure you have the GPS on while en route 
to the boundary.

The VUCC rules spell all of this out in a very simple format on the ARRL's

Hi Dave,

Like many others, I'm looking forward to working you from the quad point. 
I'll finally be home to take advantage of your operation and hopefully get 
four new ones into my own log.

Adding one point to WD9EWK's info, the GPS display needs to show an accuracy 
of 20 feet or less. Lower is better for stability of course, but 20 is the 
magic number.

Have fun!

Hi Everyone,

Just a reminder (and before the flood of ARISSat emails in the list
tomorrow!), this weekend I'll be heading out to the California Lost
Coast to work the satellites from that rare grid CM79.  CM79 has no
roads, no power, no houses, nothing but lots and lots of ocean and a
small triangle of mountainous forest.  Plans are to operate right from
the northeast tip of CM79 so if all goes well I'll be providing four
grids at once:  CM79, CM89, CN70, and CN80.

Weather looks reasonable (cloudy mornings, sunny afternoons) for
portable solar-powered operation.  I'll operate on Sunday August 7th
and Monday August 8th, and I've posted a list of potential passes on
my blog.  Operation will be during local daylight only, due to the
remoteness of the area I don't want to be hiking down off that
mountain after dark!

I'll aim to work all available satellites -- AO-51 (if it keeps going
strong like it has been), SO-50, and AO-27 for FM.  VO-52, FO-29, and
AO-07 (primarily mode B) for SSB.  If ARISSat is up and running I'll
try to get on that too, depending on congestion and satellite

I'll have my SPOT Locator beacon with me, so my exact location should
be available from the link on my QRZ web page.  If the current beacon
position shows that I'm right at the intersection of -124 and 40
degrees, likely I'll be available on the sats as they go by.
