[SD-User] SD Parallel keying - No signal to radio

[quale]

Can anybody help...?

I got myself a ready made parallel port cable, fitted according to the 
instructions with transistor and resistor, in order to handle keying output 
from logging programs.  I have checked the unit as per the accompanying 
instructions, and it seems to be in good shape.

However I do not get any CW generated on my radio (yes, the LPT1 output is 
connected to the straight key socket) neither from SD nor DXbase.   The PC 
parallel port works fine otherwise for exsternal disk-station as well as with 
printers.

Is there something I am not aware of?  I would appreciate any guidance.
