Subject: [sarex] Grid Square Posits via ISS

Steve Dimse announced the latest upgrades to the ARISS/APRS web page
including its ability to now plot grid square position reports like:

>EL94GP Comments go here

The ISS digipeated packet would look like this
 
K4HG>CQ,NOCALL*:>EL94GP Comments go here

Although this format is the minimum essential information to be parsed
and plotted by Steve's http://www.ariss.net maps, it is not sufficient to
be decoded on any other APRS software or the Kenwood front panel
displays.  To be APRS compatible, the GRID SQUARE format must include two
ICON characters on the end as in this example:

>EL94GP/- comments go here

Where the /- is the ICON for a house.  There are hundreds of other
colorful ICONs that you can use to be more descriptive of your operations.
The TWO CHARACTER combinations for all of these other ICONS are
detailed in http://web.usna.navy.mil/~bruninga/issicons.txt

de WB4APR, Bob
