WHAM4 HEPI Unlocked Currently Postion Loops Closed

Completed stripping the Ameristat from the HEPIs and unlocking the platform at 1015pdt.  Closed the HEPI loops with no difficulty.

Attached at spectra from overnight (HELI Locked) compared to after unlocking; and, comparing after unlocking to having the position loops closed.

Comparing the three states, basically it depends, some frequencies better, others, not so much.
