Is there any rise time information available, when Tone spacing is set to “x 2” or “x 4”? To my understanding those are intended for TX implementations, where signal frequency is divided by those values. Most probably in those cases digital processing is simpler without any signal slow ramp up/down.

Hello Chris, Paul, Peter,
I'm afraid I made a mistake in my earlier measurement: instead of waiting for the next half hour for FST4-1800 to start I just pressed "tune". Here I measured 0 rise time.
Today I had a look at the rise times for the real transmission start (rather than waiting 30 minutes I changed to PC clock) :
