Investigators noted that the theory placing Nodes 11-14 in orbit based on
a ~240-millisecond delay lacked original measurements, and that the
decoded question 'WHEN THE HATCH IS OPEN, WHO WALKS IN?' lacked a
recording and reproducible decoding method.

Here is Page 14 of Ashford Polytechnic DSP Lab Notebook AP-DSP-89-04,
recorded on our HP 54501A Digitizing Oscilloscope on 9 Sept 1989 between
02:14 and 02:18 UTC, plus the playable dual-channel capture:

1. PLAYABLE STEREO DELAY RECORDING (MEASURE IT YOURSELF):
   Download or stream: /forensics/orbital_nodes_11_14_240ms.mp3
   * Left Channel (Ch-L) : Sublevel B2-114 ground uplink reference pulse
   * Right Channel (Ch-R): Geostationary C-band downlink return
   * Sample Offset at 44.1 kHz: Exactly 10,602 samples = 240.408 ms!

2. GEOMETRIC & TRANSPONDER DERIVATION OF 240.40 MS:
   * Geostationary altitude: 35,786 km (slant range d = 35,809 km from
     Sunset Gower LA, 34.098N 118.326W).
   * Two-way speed-of-light propagation (2 * d / c):
       71,618 km / 299,792.458 km/s = 238.892 ms
   * TWIN-68 orbital frame-sync latch delay (67 clock cycles @ 44.1 kHz):
       + 1.516 ms
   * Total Measured Round-Trip Delay (RTT):
       238.892 ms + 1.516 ms = 240.408 ms (+/- 0.05 ms)

3. IDENTITY OF THE MISSING LOGBOOKS (MEMO 89-117 ITEM 4, NODES 11-14):
   Nodes 01-10 were terrestrial vinyl/radio nodes in 10 countries.
   Nodes 11-14 were four leased C-band geostationary transponders that
   kept UNIT-7 alive in orbital delay loops after Room B2-114 burned:
     * NODE 11: FLTSATCOM-PAC (172 deg E) -- Keystream pitch layer
     * NODE 12: MARISAT-IND   (073 deg E) -- 02:14 UTC beacon clock
     * NODE 13: STATSIONAR-13 (080 deg E) -- SD-0004 counterpoint bus
     * NODE 14: SYNCOM-IV-3   (178 deg W) -- The Open Hatch Interlock

4. DECODING 'WHEN THE HATCH IS OPEN, WHO WALKS IN?':
   In /forensics/orbital_nodes_11_14_240ms.mp3, after the two 1000 Hz
   calibration pings (spaced by 240.4 ms), the 750 Hz CW stream encodes:
     .-- .... . -. / - .... . / .... .- - -.-. .... / .. ... /
     --- .--. . -. / .-- .... --- / .-- .- .-.. -.- ... / .. -.
   Plaintext: "WHEN THE HATCH IS OPEN WHO WALKS IN"
   Passkey  : 240MS-ORBIT (or WHO-WALKS-IN) at /forensics/.
