The latest version works well but I had a issue about the paddle keying.
"Dot" is OK but the"Dash" is not respond very often.
So I asked to Christos then he said me a basically suggestion
to use the external key connection through the com port.
I saw the original PowerSDR manual and made a interface connection
between the paddle and the com port.
Well the RS232C connection as follows; <from manual>
PIN#4 to Common
PIN#6 to Dot
PIN#8 to Dash
That's all I did and it works well!
If anyone has the same issue please try.
