Paddle Connection
Plug your favorite paddles into the front panel using a standard 1/8” Stereo Plug.
To use a CW key with OpenHPSDR/PowerSDR™ you will need to enable it in the menu. To do so, click
on Setup → DSP tab followed by the Keyer tab.
Provides connection for a CW key, either straight, single-paddle or Iambic. If using dual-paddle or
Iambic mode, the common connection of the key should be made to the sleeve of a 3.5mm 1/8” stereo
plug, the “dot” side to the ring and the “dash” side to the tip. If a straight key is used, this should be
connected between the sleeve and the tip of the plug. PowerSDR Software enables the dot and dash
connections to be reversed via a menu selection [above]. The dot and dash connections are connected
to a 3.3vdc via a 1k resistor.
If you find that your DAH and DIT paddles are reversed, there is a very convenient SETUP check box to put
DAH on tip and DIT on Ring of the input PLUG
