The stored energy is in the secondary.  I only sense primary current so 
right now the box cannot see the signal to try to sync it.  The antenna 
feedback folks might be able to do this.

Right now it is very easy just to change the BPS a little until it gets a 
nice sharp streamer.  But if the things is operated there a lot, it would 
be nice for that to be automatically tuned too.  Probably vary the BPS over 
a small range to get the highest RMS primary current....
