Setting the application gain on WSJT-X to 50% (per the instructions of SignaLink) brings it right back to 100% on TX. It looks like this causes a higher ALC on the 891. I'm not sure at this time how this can be reduced, but it looks like the FT8 signal is getting out there. SignaLink set at 50% for both TX and RX knobs:
High ALC? It is unfortunate there isn't any values associated with this meter.
