The digital transmission appears unusual. I don't recall hearing that pattern before. The pattern heard in the uploaded clip appears to be a preamble. During the transmission identified as "long," the apparent preamble is heard followed by the typical pattern of a digital transmission. I'm curious if anyone else has heard this preamble before.

Vaguely recall one like this before, definitely uncommon, makes one think of The Buzzer.

Appreciate the confirmation on the rarity. You're right: certainly does sound like the buzzer.

Can't recall ever hearing that signal on HFGCS during my year of 24x7 monitoring... very odd.
