Recently I've been putting together an APRS i-gate with an APRS Track X1C3 and a Baofeng GT3-WP which seems to work quite well connected to my W300 2m / 70cm vertical antenna on the roof.
I was able to send APRS tracks from my Anytone 878 in my car for about a three mile radius from the house. The setting up of the X1C3 was fairly straight forward but what I did struggle with was finding an application to run on my computer as the interface to the internet. I've tried quite a few now and Pinpoint seems to be one of the better ones as it's a well thought out user interface that makes it intuitive to use and a much easier learning curve than some of the other applications.
