Hi All
         PMmap is dead and no longer will be available.
I have taken PMmap and removed Precision Mapping from it.
Since the PM in PMmap stood for Precision Mapping I have renamed 
PMmap to APRS-SCS.

So now there should be no confusion what type of Software APRS-SCS 
is. It obviously is a new old 32 bit Windows Based APRS client 

APRS-SCS has a lot of neat features but one of the neatest is the 
fact that the user does not have to buy, or make Maps.
APRS-SCS uses the USGS 20000 mapping data. 

What this means is that APRS-SCS makes its maps on the fly. All the 
user has to do is input the map center and the map range and APRS-SCS 
does the rest.
The maps that APRS-SCS displays are fully zoomable.

Yes the Maps that APRS-SCS displays look like APRSdos maps. That is 
because APRS-SCS and APRSdos now use the same data. The difference is 
that with APRSdos you had to make the maps first. APRS-SCS uses the 
USGS data directly displaying the maps in real time.

APRS-SCS like PMmap can be thought of the Windows version of APRSdos.

Now that I am using the USGS data it has given me more control over 
my displaying of APRS symbols. The color of the APRS Station call 
signs match the color of the APRSdos symbols. Giving the user a 
visual clue as to what the station is .

For example Stations with white call signs are message capable
stations with gray call signs are not message capable.
Objects with violet call signs are objects that are being transmitted 
by other stations. Objects with yellow call signs are being 
transmitted by your station etc....

To my knowledge APRS-SCS and APRSdos are the only APRS software that 
gives its user this visual clue. 

At this time I would like to publicly Thank John N8UR and the rest of 
TAPR for hosting APRS-SCS.  Thank You.

My old web page would have been too slow to down load the 13 megs of 
zipped up USGS data. Thank You TAPR for without you I could not offer 
APRS-SCS to the amateur radio community.

Thank you all for your time in reading this. 
Let us hope we never witness the "Silence Of The Hams"
