For my APRS project, I was looking for a TNC (Terminal Node Controller) which can activate my radio. When searching the internet, I did find this tnc in America. After a quick delivery (received on 07-02-2015) I start building my first real kit. Only the SMD chip was already soldert.
The first test were promising, the unit received audio, all the chips were getting a stable voltage. So the next step would be, connecting to a radio and send some beacons.
If this TNC is completed, I can go further with my car aprs setup.
So be continued…
