Windows
Set Windows audio playback device to 100%, disable all enhancements, and set default format to 1 channel, 48000 Hz.
Set Windows audio recording device so that the green RX bar in WSJT-X is around 30% on a quiet band/frequency. Set default format to 1 channel, 48000 Hz.
Label the audio devices as “IC-7300”.
When transmitting, adjust Pwr slider in WSJT-X until it begins to tickle the ALC meter. Forward power should now be around 28W.
