Can you expand on this setup please?  I would like to emulate it.

Enabling conditions include Hi_SWR false and TS-590 power set and verified.  Set drive power is not allowed to exceed 120% of band max drive power.  (That overhead allows the psychological boost of turning the wick up when chasing needed DX but prevents doing anything too stupid.)
