How does this missed approach work?

I didn't say to not play the initial "get your attention" alarm. I was only referring to the silliness of a follow up alarm once your attention is already there.

I suppose a corner case would be another aircraft popping up ALSO squawking 7600 inside that "silence ring" calculated around the first one, but that's likely to be close enough that the snitch alarm would cover that one. Or the software could simply count. One aircraft silenced, inside this ring, second shows up, play the alarm again.

With proper analysis of the problem, there's no need to re-alarm on already known things every time the radar antenna goes roundy-round.

We have to deal with the system the way it actually functions, not in the way we might prefer that it function.
 
I cannot imagine a scenario where it would. I welcome your attempt.

I was just wondering if it could cause a controller to waste time on additional calls, due to thinking that the cessation of the 7600 squawk might be an indication that the comm problem had been resolved.

With the cessation of the 7600 squawk the controller will first sense relief that the alarm has stopped, if he's in a facility so affected. How would the pilot know the comm problem has been resolved other than by having restored contact with ATC? ATC will call the pilot periodically without regard to the code until contact is made and no contact means the aircraft is still NORDO no matter what code is set.

IME, in most NORDO situations, the pilot isn't even aware that he's considered NORDO by ATC. For some reason a pilot doesn't respond to ATC. ATC calls a few more times, no response, he's deemed NORDO and that info is passed along. The pilot chugs along until he wants lower, or crosses an ARTCC boundary, or just feels something's amiss. Then he starts calling ATC facilities until he finds one that can tell him where he belongs.
 
Thanks. In light of that, and since continuing to squawk 7600 is not a regulatory requirement, I don't see a compelling reason not to adopt the procedure you suggest.
