    In the field

    The DSP2 on 135.650 MHz in the car, and the live transcripts coming in on the laptop. The audio is the approach frequency itself.
    This page playing back the session: arrivals moving along the Quiet Bridge flow as the timeline advances.

    Transcripts are raw output from the Mac's on-device speech recognizer, which handles aviation phraseology poorly; the interpretations are a best reading. Callsign digits are approximate: 2619/2319/2019, 685/868 and 660/3660 may each be one flight heard differently. The facility and runway are stated on the air: Delta 689 checks in with "NorCal Approach" and Alaska 688 is "cleared visual 28 left"; SFO and the Quiet Bridge Visual are inferred from those plus "at the bridge, contact tower". Flights handed to the tower more than 90 seconds earlier are parked at SFO on the map. Received on a Malahit DSP2, AM, 135.650 MHz.
