To corroborate the Paju DMZ 'Fifth Tunnel' claims (Node 03) with original
engineering dimensions and reproducible physics, here is the acoustic
survey data from ROK Ministry of Construction / Corps of Engineers
Addendum ROK-ENG-87-PAJU5 (Surveyed 19 Nov 1987, Sector 37d55mN 126d41mE,
Consultant: M. HALE / Orion Pacific Engineering):

1. REPRODUCIBLE STANDING-WAVE CALCULATION:
   In a rigid-walled granite gallery closed at the driver face and
   terminated by an acoustic impedance step at L_1/2 = 12.000 meters
   (full wavelength lambda = 2 * L_1/2 = 24.000 meters):

     f_0 = v / (2 * L_1/2)
         = 340.8024 m/s / (2 * 12.000 m)
         = 340.8024 / 24.000
         = 14.2001 Hz

2. MEASURED TRANSDUCER & VINYL CORRELATION:
   Bolted to the northern granite bulkhead was a 400-watt magnetostrictive
   seismic/acoustic driver clocked by a Motorola 68000 controller etched
   'STARDUST NODE 03 -- THE CRACK RUNS UNDER THE BORDER'.
   When the 1985 Korean Jigu Records pressing of SYNTHESIS (Catalog
   JLP-8514) is played simultaneously, its +0.4480 Hz phase lead locks to
   the Paju borehole resonance with 94.6 dB SPL at 14.2001 Hz.

Enter passkey PAJU-1420 at /forensics/ to log Node 03 into the 14-Node
Synthesis Matrix.
