I had the same problem this morning, actually. I'm looking into increasing decoder speed any way that I can...I did find that I should not have had the AGC on (I did) and I should have had the audio gain lower than it was (I had to turn it UP for JS8Call). Apparently there are other decode speed options in WSJT-X, so I'm going to try those. Additionally, I had the Quadra running off my tenuous phone Hotspot to keep time, while waiting for my GPS dongle to come in...since Conky is running to keep the time accurate regardless of the input, I assume that some processing will be freed when it isn't relying on NTP but using direct input.?
What was your setup?
I may end up running a PI variation headless off my tablet eventually. The Quadra was cheaper and appealed to my wallet XD
