Mike,

Check out GcmWin (Great Circle Maps) from Roger, SM3GSJ at URL
http://www.qsl.net/sm3gsj/index.htm.  This is not exactly what you are
looking for, but it does a good job of plotting your grid squares on a map.
It can plot from two different grid square lists as well, so you can
highlight confirmed vs. worked grids, for example, in different colors or
shades.  It does have the capability of adding boundaries--so state outlines
could be added, but so far no support for shading in the boundaries as far
as I know.

Been having lots of fun with new rooftop sat antennas.  What I would like to
do is attempt to work all states via AO-51, but I am struggling with a good
layout to keep myself motivated.
Does anyone know of a logging program I could display on a flat screen
specific to sats?
Here is my thought:
A google maps overlay that has states and gridsquares on it (does this exist
today as overlays for Google Earth maybe?)
Then Iog my sat contacts on AO-51 into a logging program (LOTW or something
else).
Then it gives me an output overlay for Google so I can see all states and
gridsquares worked.
It would be great if it could color in the states I have worked and/or the
grids I have worked on zoomin.
Well, I know it is a lot to ask and maybe it has to be designed, but it
certainly sounded interesting to me.  It would really be nice when scouts or
family come over to show them the states I have worked on AO-51 and/or
others in a visual display.
Thanks for any ideas or any pointers into anything close or at least a good
sat logging program that maybe I can export a file to utilize in Google
Earth to make a KMZ out of or something.

I will try to do the same. I have a borrowed computer here for the time
being, so don't have all my usual software complement installed, but
will cobble something together.

Good Afternoon Bob,

Sealing may not be the answer. There are many ways water/moisture can enter.

Water ingress can happen at gaskets, coax penetration points, DC
penetration points,
connector flanges, mounting screws, cover screws, etc. Coax can even
"hose" water inside.

I suggest limiting the moisture entry AND allow it to drain out the
bottom. This vent hole will
also allow the pressure to equalize, inside vs. outside.
If the enclosure breathes there is no pressure or vacuum buildup inside.
Vent hole can be small, just big enough to keep the bugs out. ~1/8" is
on the big side.
Let gravity work for you, put the vent hole on the lowest point.

One scenario includes a hot summer day and the air inside the sealed
enclosure expands.
A thunder storm comes along with much cooler temps and rain. The
enclosure is cooled and doused.
A vacuum builds up inside and any moisture is sucked in thru any and
every possible entry.
This vacuum may exist overnight > 8 hours, so it has a long time to "work".
The moisture  and acid rain starts to corrode everything inside.
Electricity tends to accelerate the corrosion.
With a functioning vent hole, the sucking and blowing is controlled and
no significant differential pressure from inside to outside.

So, what is the solution in a rain/wet environment ?

Let the item breathe, allow air to circulate.
Keep the rain/snow from falling onto the item, cover it up.
If you use an enclosure be sure to vent it.

Avoid dissimilar metals that will only corrode, no plated steel hardware
or phono connectors.
Use sealed/potted relays.

For items outside where weight is not a problem, I will design a
connection point so I can put a
bucket or waste basket over it to keep the rain off. An open bottom, so
everything can breathe.
The plastic container must be UV proof. A black plastic waste basket of
different sizes is my favorite.

My old KLM 22 element 2M Xpol has an open polarity select PCB on the
antenna boom,
but I sealed up the relay and I removed all plated steel hardware and
connector, direct solder wires.
Then I gave it all a few coats of a clear coat spray.

Do not use RTV that smells like vinegar (acetic acid),it only
accelerates corrosion.
I have used the 3M 5200 series sealants with success.

Most of the Landwehr mast mounted preamplifiers directly exposed to the
weather will leak.
Probably why they are no longer on the market and have sought other
business opportunities.

Document performance so you can compare later test results.

moisture (Yes I live near Seattle) in the box.  Lots of yuck and rust, on
non stainless steel hardware..  The 12V connector is a simple phono plug,
which should never be used outside.  Before I reinvent the wheel has anyone
been here before?  Replace the phono plug, sealing everything.  In the past
I have used a material called 3M5200, a marine sealant, nasty but almost
permanent.  Suggestions please.
