The Recommendation: If your meter is currently powering on, locking DVB-S/S2 signals (QPSK/8PSK), and displaying spectrum data correctly, do not attempt to update the firmware.
The risk of bricking the device for minimal gain (usually just an updated satellite list that you can manually edit yourself) is too high. The WS-6933 is a tool; if it is doing the job it was designed for, leave it alone.
The Solution for Modern Installations: If you are running into signals you cannot lock due to modulation changes (16APSK/S2X), software is not the answer. The WS-6933 has reached the end of its service life for forward-compatibility. It remains an excellent tool for legacy KU-band alignment and standard DVB-S2 installs, but it is time to consider upgrading to a meter with a hardware S2X tuner (such as the WS-6983 or a dedicated tablet-based solution like the Promax or Rover meters).
Just as your smartphone needs updates, the WS-6933 benefits from optimized memory management and faster boot times. satlink ws-6933 software update
