Re: [TCML] DRSSTC tuning at high power



I would try more tuning, ive seen that response before and ive seen it get
tuned out a lot better than what i see here.  Though at the same time that
is a lot of cycles and its hard to keep it in tune on that time scale.  Im
really surprised you need that many cycles of drive even.  From the looks of
it, i'd probably shut off after 5 cycles.  What bus voltage do you run at?
 Maybe you just need more voltage drive and less cycles.
