New USB version of the APRS TNC Digi Tracker now released

We have now built up enough stock to finally release the new USB
version of our APRS TNC Digi Tracker.

It now has a USB port so that it can work with modern laptops,
notebooks and PCs.

It can be powered by either the 12V input on the 9 way D type radio
port or by the 5V feed through the USB port. This makes it very easy
to use with a notebook and handheld. The Digi Tracker is powered
through the USB cable and the Tx, Rx audio and PTT lines are connected
to the handheld radio.

It comes with a built in Sirf III GPS receiver with a SMA connector
for an external GPS antenna.

I've been using the prototype in my car over the last six months as a
tracker. It's fun to have the option to plug a USB cable between the
Digi Tracker and notebook for lunchtime portable APRS operation.

I've updated the web page with more details and an Operating Manual of
the USB version:

I've also made a new web page for the APRS Messenger Lite freeware
program that can program the new version using any PC Comm port up to
Comm 255 and also run as a receive only igate as well. The new web
page is:
