March 2024 update: Gaijin is changing how mode switching works on some radars. Now you will have ACQ AUT / ACM AUT / HMD AUT, where AUT means Auto and you can't manually pick mode anymore, the radar will do it for you.
TRK MEM is memory track where the radar is trying to extrapolate the position of the enemy. This is a new name for an existing mechanic.
