Mike, I have used my FT-847 with both sound cards and TNCs for years. There is nothing special about the TNC needed. It does 1200 and 9600 baud out of the box, but as Mark mentioned, going faster requires some modifications. The connector is a standard computer type 6 pin connector, as others have mentioned. I think Yaesu still has them, but cutting the end off an old PS/2 mouse or keyboard extention is cheaper. Note that some of those cables only have 5 wires, even though they have 6 pins. There is a very good FAQ to be found here:

The manual has some good info as well. 73s, Alan WA4SCA _______________________________________________ Sent via amsat...@amsat.org. Opinions expressed are those of the author.
