Paccomm Tiny-2 Factory Mod

Here ise "Factory" fix for Pac-Comm Tiny-2's & Micro-Power 2's that have become hard of hearing. 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 underside of a 16 pin IC socket, the Modem chip TCM3105 (U16) is removed, the modified socket is inserted into existing socket onC's board, and the modem chip is re-installed.

Parts Needed:
1 - 16 pin IC socket
1 - 2222 Transistor NPN (EGC AP)
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
