Since firmware version 20200525:
... the lower frequency limit seems to be 10 kHz.

VNA-QT allows only 100 kHz (also for calibrating).
In NanoVNA-saver 10 kHz (and even lower) can be set.

Do you know, why VNA-QT doesn't allow 10 kHz or at least 50 kHz?
Is there a special reason for this limitation?
I'm asking, because I sometimes measure in the VLF range.
