The most common request for WS-6933 firmware updates stems from an inability to lock specific transponders. If you are attempting to lock a modern high-efficiency transponder, no software update will help.
The WS-6933 hardware tuner is natively designed for DVB-S and DVB-S2 (QPSK/8PSK). Modern satellites (particularly high-throughput satellites like Eutelsat Konnect or Yahsat) are increasingly utilizing: satlink ws-6933 software update
While the processor in the WS-6933 might theoretically be able to interpret the stream if the firmware were rewritten, the tuner demodulator hardware lacks the silicon logic to demodulate 16APSK or S2X signals. If you are scanning a frequency and getting "No Signal" despite strong carrier power on the spectrum analyzer, the issue is likely hardware obsolescence, not outdated firmware.
