open the Windows Sound Control Panel and select the
"Playback" tab.

double click "Headset Earphone (microHAM

●
click Balance and set LEFT (1) to 80% and RIGHT
(2) to 100%
NOTE: to enable "p-FSK" or “q-CW” audio keying on the
right channel, the Headset Earphone and right channel (2)
level must be at 100%. The audio detector will not operate properly at any value below 90%.
6. Switch your transceiver to AFSK mode (PKT, DIG or DATA for Yaesu, LSB-D or USB-D for current
Icom transceivers, RTTY or RTTY-R on K2 and USB or LSB for Kenwood, TenTec and older Icom
transceivers). Do not select RTTY or FSK; they do not use the audio input.
IMPORTANT: Many transceivers, including all Yaesu transceivers, MUST be switched to special
digital mode (DIG, PKT, DATA, USB-D/LSB-D etc.) to enable the rear panel line input!
7. Click the "Test Signal" button and adjust the LEFT level for normal (rated) output on your transceiver
while keeping the ALC meter as low as possible. Turn off the Test Signal.
NOTE: For the Elecraft K3 and other transceivers that have a separate “line In” control, do not
adjust the LEFT slider. Instead, adjust the transceiver Line In level (mic gain) until the ALC shows
the correct level.
