You need to match your Yaeseu radio configuration settings with the ALSA
settings used to config DRAWS.


If your radio is set for DATA (PSK) operation use ALSA settings IN2_L &
IN2_R. Turn OFF IN1_L & IN1_L

If your radio is set for RTTY (FSK) operation use ALSA settings IN1_L &

See pages page 62-66 of manual FT-891_Advance_Manual_ENG_1806-F.pdf
Yaesu mDin6 pin 4 is labeled SHIFT, this is Discout on other radios.
Also see page 25 of manual FT-891_OM_ENG_EH065H201_1611A-BO-2.pdf

See page 41 FT-817ND_OM_ENG_E13771011.pdf

Different connections are used for 1200 & 9600 (AFOUT & DISCOUT)

ALSA settings
Use IN1_L IN1_R for 9600 baud (DISCOUT)
Use IN2_L IN2_R for 1200 baud or less (AFOUT)

Radio settings
Use Menu #40 (PKT RATE) to select DISCOUT or AFOUT
Also Menu #39 (PKT MIC) allows adjusting drive level.
