Yes, so it was an even divisible clock for the fastest possible time steps.
Maybe not needed any more with the changed transformer primary turns using higher volts at the input and lower amps
to get the same output. The driving transistors seem better able to put out with the newer transformer primary turns number
and turns ratio.
Here's what I was using to set frequency:
# boot.py -- run on boot-up
# can run arbitrary Python, but best to keep it minimal
import machine
import pyb
pyb.freq(96000000)
pyb.main('hv_pulser.py') # main script to run after this one
