I'm always a sucker for technicalities, and "Omega Glory" indeed has a couple to offer (it's also interesting to learn about the amount of ammo available in a hand phaser - that is, enough to kill one army but not two - and the fact that phasers can leave battlefields littered with corpses). Let's have a shot...
Sulu announces the ship is approaching Omega IV and a vessel has been sighted. Kirk immediately orders a red alert. It is unclear why such a move is necessary without even determining the vessel's identity or status or attempting the hail the other ship.
The teaser makes it sound like Kirk is just cruising about, not e.g. performing a specific mission at Omega IV - after all, Sulu has to inform Kirk of the identity of the planet they are approaching. OTOH, we know Kirk isn't looking for the
Exeter specifically, as he hasn't heard of any trouble regarding that ship. And since the
Exeter was patrolling this area half a year previously without trouble, the area in question probably isn't "troubled", either.
What's left here? Kirk isn't at Omega for Omega itself, or for the
Exeter, or because the region in general is a hot zone. But he sounds an alert at the first hint of an unidentified vessel, and interestingly enough, everybody understands it's going to be a red alert rather than a yellow one without Kirk saying so. What it looks like, then, is that
this is what they have been tasked to do: scour the region for an unidentified vessel. Perhaps there's a pirate loose, or a fugitive of some other sort; perhaps Klingon agents are again afoot, like in the recent "A Private Little War"?
Finding the
Exeter naturally takes precedence, as Kirk has no idea that the encounter is going to take a long time to sort out...
(1: It's clearly established in TOS that Spock is a touch-telepath. (2: It makes no sense as to why Sulu would be standing by to beam down just because the Enterprise receives "dead air". (3: It makes even less sense that Sulu would recruit volunteers to beam down when he knows they will be subjected to a contagion. (4: It makes even less sense that Sulu would beam down with a well-armed party with the Prime Directive obviously still in force.
1) Spock does have a range of other "paranormal" abilities. He can sense across interstellar distances that Alderaan is gone, or that his girlfriend is expecting. He can also influence people to do his bidding (and defy their orders) through walls. Influencing a person to do something fairly innocent across the room shouldn't be a major deviation, then - nor would it be something that would have altered the plots of previous episodes. The "Taste of Armageddon" ability to make a guard defy his orders is the more serious aberration and plot twister...
2) We might argue that instead of static, Sulu receives the sounds of the knifefight, then Cloud William's threatening words "Kill him!". OTOH, since Spock is in possession of the communicator while the camera is turned away, he could be doing just about anything, from speaking to Sulu in a low voice, to pressing the button marked "Emergency Armed Response".
3/4) If Spock briefly explained the situation to Sulu, there'd be no contradiction. But it would suffice if Sulu somehow learned that Spock was indeed the one calling for the intervention. Sulu could then readily assume that Spock knew what he was doing.
Just pressing the "Rescue Us Now" button wouldn't convince Sulu; any silly primitive might have found the button by accident. Just hearing the sounds of the fight wouldn't suffice, either. But if Spock managed to utter a codeword, that'd certainly be enough. And we know that there are standard codes that don't need prearranging, such as Kirk's "Condition Green" from "Bread and Circuses". Perhaps Spock got in "Condition Amber" in his own identifiable voice?
There's certainly enough time for Sulu to rush to help, because the knifefight is supposed to be a protracted struggle, and there are cuts in that action.

P.S. Yeah, I like this one. It's a convincing and interesting scifi dilemma that traps our heroes down there, and the characters are intriguing enough. All we're missing is Spock speculating that a time traveler who happens to be a United States fan is behind the original, thousand-year-old intervention in Omegan affairs...
