Fred,
BE9 pin 7 connects (through the internal cable) to the microprocessor
VRFDET signal for use in detection of the power output level.
As a result it is not available for other uses. You will have to find
another path.

I use N1MM contest logging program. At present, I communicate between the PC
and the K2 with its KIO2 using a serial cable, and I key the K2 using a
parallel cable with Tom's (N0SS) keyer built into the parallel cable housing.
With parallel ports absent from many laptops, and in the interest of fewer
cables...
My question(s):
The KIO2 uses pin 2 and pin 3 for RXD and TXD communication with the radio, and
pin 5 for the ground connection.
1) Can I use pin 7, on the KIO2 labeled RF but appears that nothing is connected to it, to drive transistor keying of the radio instead of the parallel port?
