This setting controls whether the CSAT unit's transmitter remains muted after a frequency change or automatically unmutes, configured via the MUT= command. This matters because briefly muting output during a frequency retune prevents transmitting on the wrong frequency momentarily, which could cause interference with adjacent satellite channels. For example, an admin performing frequent frequency adjustments during commissioning might set csat5060UnitMuteMode to mutedAfterFreqChange to require a manual unmute step as a safety check before each retune takes effect on-air.
