Wintec WBT-100
Overview
The Wintec WBT-100 is a GPS receiver with WAAS, bluetooth, USB, a compass, and a datalogger all in one very small package.
I got one 4/12/2007.
Software is at Version 2.85 -- 6/29/2007 It can now log HDOP.
The support site is http://www.wintec.com.tw/
I bought the receiver from Semsons.
Operation
Normally I use it when hiking. I turn it on and put it into the pocket on my Trimble antenna hat, and forget its there until I get home. Then I download the data and clear its log.
Data transfer
You can talk to it with the provided Wintec Windows software. This is my preferred method right now but you can also talk to it with GPSbabel which means Linux or Mac or Windows.
For example to transfer tracks and waypoints from the device to a GPX file, you can say
~/bin/gpsbabel -t -w -i wbt -f /dev/ttyUSB0 -o gpx -F buenavista.gpx

For a Ruby version of a program that can talk to a WBT-201, see http://www.daria.co.uk/gps
The reason for using the Wintec software instead of gpsbabel is that it can clear out old logs and it can change system settings; for example it can change the mode used to log.
