How does it work inside SparkSDR. Fo I need JS8Call open alongside SparkSDR? I do not know also how I can use FreeSDR, do I need another software open alongside SparkSDR?

Hi Pierre,

the JS8 mode in spark is very similar to the FT8 mode. If you use level 0 you don't need any other programs running or installed, it is all done inside spark. If you use levels 1 to 3 you need JS8Call installed in the default location but it does not need to be running. Alternatively you can use the digiu mode and connect to JS8Call with vac and cat. The freeDV mode also does not need anything else installed or running.

About JS8: do I need to write some settings? If I look at the settings "FT/FT/WSPR the link is to the WSJT-X directory in my computer, how can I link SparkSDR to my JS8Call directory?

About levels 1 to 3, do you mean the "decode depth" box?

My priority today is to run properly JS8 with SpartkSDR. I can already run JS8Call with Quisk. I feel JT8 is not funny at all: you just click once or twice on a button and the computer does the job, you don't even need to remain in the shack! JS8 allows you to interact with the other OM, this is true Ham Radio. Well I can run JS8Call with Quisk but my by far preferred SDR Software is SparkSDR, I already wrote that Hi! But I still missed something in the settings...
