Hi everyone.  I was part of the Teachers Institute 2 last summer at ARRL headquarters in CT.  Tons of great ideas, but now that it has been several months, and I have disassembled things I can't remember how some of the equipment was used.  Specifically, are there any TI2 alumni who have been using the Argent Radio Shield 1 with Arduino to do APRS?  I could use some help finding how to connect and shield to the Arduino Uno with the right pinout connections and Arduino code.  Does anyone have that info that can help me?  Thanks all.
