I really like the design of this ICSP pad. I'm considering using something like it in the next TNC.

New TNCs coming next week. Micro-USB and brighter LEDs.

A small update to the TNC2 is coming in December.  Micro-USB and better LED visibility are the biggest changes people will see.  Below is a final prototype board.

I was testing a prototype TNC today and captured this APRS traffic of +TeamAeroDynamix   practicing their performance for this weekend's Chicago Air and Water Show.

I had received the PCBs from +OSH Park  on Monday and finished the build yesterday.  I turned on the TNC this morning to see how it would do and captured this while at work.  I was really surprised to see this when I got home.

I am in the perfect spot to capture this.  They were doing tight turns over the home office.  I had the iGate turned off, so much of this did not make it into APRS-IS.

Ciprian Florea, YO2LOR has created a really cool custom TNC2 clone.  He built a small PCB that fits inside a Baofeng 3800mAh battery case and draws power directly from the battery.  It's running the stock Mobilinkd TNC2 firmware.

Jerry Clement, VE6AB, wrote a very nice article on APRS in the May 2015 QST.  It provides an introduction to setting up a portable APRS system with a Mobilinkd TNC and APRSdroid.

Another Arduino-based TNC!  Check out this cool board from unsigned.io.  Keep supporting open source and open hardware in ham radio!
