Okay this is different. The frequency was quiet until about 1:20pm. Suddenly, I hear a beep and then several beeps and then more. It sounded like a CW identifier. I was mobile and just happen to be listening at the time. I noticed that it's off right now.

I'll try to capture this audio and see if it decodes. Hopefully, it'll happen again tomorrow.

Whoa, that thing works!?

The Zetron 38A tone panels have a feature called "Tone Reservation" or something similar. It will beep over the air if someone comes up on a "Reserved Tone".

Possibly something like that?

I'm now hearing a steady tone. Full quieting signal at my place in DT Bellevue. It's definitely not a standard 1950 or 2175 tone you'd hear from a voting receiver or anything like that.
