[SD-User] CW keyer issue

[Brad Anbro <n9en@live.com>]

​Hello all,

I recently installed SD on my Windows 7 Professional machine. I am trying to 
use my
home-made CW keyer, which utilizes the serial port (COM1). My interface uses a
single 2N4401 transistor and a 1K resistor.

The interface works just fine with my "CT" software but seems to key my HF rig
continuously. Am I doing something wrong in the set-up?

Thanks for any help!
