SideKar Extreme User Manual rev 2.1 Page 28 of 87
Since the Elecraft ACC port is not in use, control of the
rig and display of decoded characters are not possible,
which is why this method is not recommended.
For Non-Elecraft rigs,
plug your paddle into the PADDLE port
on the right side of the SideKar Extreme and connect a mono
or stereo cable with 3.5mm connectors (right-angle is best)
from the KEYOUT port to your rig’s key input. Set the rig to
straight key for the paddle keying mode.
In this manner the keying is done by the WinKeyer and the
functions above (speed, mode, paddle swap) are all accessible
from the keyboard.
