Hi FL,

The rig is continuosly keyed.  Then when there is a charactor keyed it cuts 
out the keying.  In other words the spacing is keyed.  I tried reversing the 
emittor and collector on the NPN transistor but haven't tried reversing the 
emittor base connections.  I use on old Yaesu tranceiver that works fine 
with the LTP an CT CW.  I guess i might try a larger value on the resistor.  
Now it's a 1K as shown in the curcuit.

Tnx,

Victor KD2HE
