[Victor Carnuccio]

Its the same circuit I used for the LPT output form ct.  A PNP transistor.  
There's 9v across the ground and pin 4 continuous that keys the circuit on 
my FT-ONE.  When it keys the CW charactors switch the voltage off.  I tried 
using the computer ground as well. That didn't do anything.  It may be 
somthing about the motherboard I am using.  It's and Asus.  Anyway I have a 
few moer days before WAE to resolve this.

73... thanks for the help
