I'm trying to get Sound Card FSK working with my FT-1000MP.

I rigged up a circuit, using two 2N2222 Transistors, for
PTT and SHIFT. PTT works, but the radio doesn't shift.

Am I correct in the following hookup for a 25 pin COM port?
db-25 pin 20 SHIFT
db-25 pin 4 PTT
db-25 pin 7 GND

I can make the radio shift if I physically short the
collector of the 2N2222 SHIFT transistor to ground, so I
think the wiring is ok on the Yaesu side. What could I be
missing here? Thanks

David, W7WW
