check out a $30 four-speed KISS TNC for $30 called "NinoTNC". Also a ham radio cable manufacturer called hammadeparts.com Beware that the Baofeng radio has many configurable elements, some of which get in the way of doing packet. Also, the radios are built like crap and can hurt you during operation. There are used radios like the Kenwood TK760g for not much more than a Baofeng but they do 25watts output. < %70 each. Sometimes down to $30.
