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.
Why don't you post exactly what this interface is.
I tried reversing the
emittor and collector on the NPN transistor but haven't tried reversing the
emittor base connections.
You sgouldn't have to experiment like that . Make sure you know the
transistor
pin out.
I use on old Yaesu tranceiver that works fine
How old is old ? Solid state ? No tube type keying?
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
