It seems that Pac-Comm has some boards out that work fine when new, but with age the tnc requires a huge amount of Audio input from the speaker jack or it won't decode properly. They are lost as to what is deterioating in the boards but offer this fix to its customers. It is quite simple and very neat, all parts are mounted on the under- side of a 16 pin IC socket, the Modem chip TCM3105 (U16) is removed, the modified socket is inserted into existing socket on TNC's board, and the modem chip is re-installed. Parts Needed: 1 - 16 pin IC socket 1 - 2222 Transistor NPN (EGC 123AP) 2 - 10000 ohm 5% resistors (brown-black-orange-gold) Instructions: Solder 1 resistor to Emitter, other end of resistor to pin 12 Solder 1 resistor to Base, other end to pin 2 Solder collector to pin 5 >EndFile<  Amsterdam View Our Stats   CLICK FOR A FREE DOMAIN NAMES HTTP://WWW.YOURNAME.TK FOR YOUR OWN WEBSITE IF YOU CLICK HERE AND YOU CAN VOTE FOR OUR FREE WEBSITES IN THE TOP 100 LIST  WANT A TOP RANKING ?
