Hi Dan, call is CT1DRB, name is David and qth is near Lisbon. I have been testing your aprs tracker and it seems very interesting for my needs, mainly SOTA activities. According to your small film in youtube, your software shows up the voltage and temp, how did you configure it ? I am using a TinyTrak4 if that matters. Best 73 and till next email.
