I've been running FT8 perfectly on my Mac with the Signalink. The other morning the internet was down. When I went to use FT8 with WSJTX it would not decode, yet the waterfall was FULL.. I checked the clock and it's in perfect synch. When the internet returned so did FT*. I didn't think it used the internet on FT8. Is this normal?? Or is this a MAC thing.?? (I have a Mac but I am NOT a fan..) Any thought?
