Correct - I use kiwirecorder to pull in a four sequential, 15 second WAV files, which equates to four FT8 transmission windows per minute. This is on a single band and produces up to 25+ FT8 call signs decodes per quarter or >100 per minute. I then switch bands and repeat.

I use cron to schedule which bands I concentrate on, mainly 160-17m at nite and 40-10m during the day. I can usually revisit a band once every 5 minutes and that has produced daily copies over the last few weeks that look like this

I've recently started to experiment with 630m, but down there most people are running the WSJT-X JT9 mode. Fortunately I can use the same technique as above, though instead I use kiwirecorder to capture a full minute of WAV audio, or 1 JT9 transmission sequence and then handing that off to the WSJT-X "jt9" command line decoder I compiled earlier, just with a different command line option (-9 instead of -8) to decode that mode. I had to tweak my PSKreporter upload script slightly to handle this, but the result is good and can be seen

Its nice to have everything self contained on the KiwiSDR/BeagleBone, but I will experiment with running all this on a multi-core RPi to see how many simultaneous bands I can run using the KiwiSDR that way.
