P.S. TH GARMIN GPS-15 SERIES IS NOT A TIMING RECEIVER !

************

Norm,

You may want to consider getting an OEM GPS board from Garmin.  You can
buy it directly from them.  The unit I am referring to is the GPS-15H/L
which is now replaced by the GPS-15xH/L and sells for
$53.50 plus shipping and tax, if any.

I had purchased the model before the "x" version and it came with the
little header plug and a few inches of wire so you could wire it into
your own arrangement.  You have to buy the antenna
separately and they also have a short antenna jumper cable to go from
the tiny connector to a BNC.

It will do NEMA and GARMIN sentences.  It is very small and very thin. 
Here is the link to it:

https://buy.garmin.com/shop/shop.do?cID=158&pID=68314#featureTab

There are TABS to select features/specs/in the
box/versions/accessories.  Also on the right side of the screen are
links to download the manual so you can read all about it.  I think the
versions are
mostly either low voltage or 8 to 40 volts, but there may be other
differences.
