I don't know if S&T will work directly with the Earthmate, but an alternative, would be employing DeLorme's Serial emulator, and making S&T look at one of the 2 serial ports it emulates NMEA format on..
Let's see.. link... link..
discussion already talking about the emulator here....viewtopic.php?f=12&t=250&p=713
Ah! link for the emulator (Windows)http://www.delorme.com/support/SupportT ... spx?id=319
S&T 2008 doesn't see the device as a USB port, so it needs to be via one of the emulated serial ports from the program..
I seem to remember, seeing a Pharos "Puck" antenna, that looked identical to Microsoft's, but may have different firmware. m ight be another thing to look into....
(their Bluetooth receiver antenna looks near identical to the Microsoft "Puck"..)http://www.pharosgps.com/products/prodd ... .1&cat=147
Hope this is of some help.
