Sentita oggi pomeriggio alle 15:30 circa su 22376 KHz/USB in SITOR-B  la stazione della USCG (US Coast Guard) di Apra Harbour da Guam, che con call NRV trasmette le previsioni e la situazione meteo per l'Oceano Pacifico elaborate dal NOAA, come dal program schedule visibile all'indirizzo:

Ricezione con FDM-S1 e miniwhip, decodifica con krypto500
  Questo il testo del messaggio completo:

HI/111951ZAPR2014//
AMPN/REF A IS A TROPICAL CYCLONE WARNING.//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (REMNANTS OF TD 05W) PREVIOUSLY
LOCATED NEAR 9.7N 130.8E, IS NOW LOCATED NEAR 10.7N 129.9E,
APPROXIMATELY 350 NM NORTHWEST OF PALAU. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A BROAD, ELONGATING, AND FULLY EXPOSED LOW
LEVEL CIRCULATION WITH FLARING CONVECTION ALONG THE NORTHWEST
QUADRANT. A 130109Z ASCAT PASS REVEALS THE BROAD NATURE OF THE
SYSTEM WITH THE MAX WINDS (15 TO 20 KNOTS) LOCATED IN THE OUTER
PERIPHERIES WHILE THE CENTRAL CORE WINDS REMAIN RELATIVELY WEAK (05
TO 10 KNOTS). UPPER LEVEL ANALYSIS REVEALS A POOR ENVIRONMENT
CHARACTERIZED BY MODERATE EASTERLY VERTICAL WIND SHEAR (10 TO 15
KNOTS) AND WEAK EASTERLY DIFFLUENCE. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
      (2) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.5N
166.0E, HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (3) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 121800Z, TROPICAL CYCLONE 23P (ITA) WAS LOCATED NEAR
17.8S 146.0E, APPROXIMATELY 55 NM SOUTH-SOUTHEAST OF CAIRNS,
AUSTRALIA, AND HAD TRACKED SOUTHEASTWARD AT 08 KNOTS OVER THE PAST
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45
KNOTS GUSTING TO 55 KNOTS. SEE REF A (WTPS31 PGTW 122100) FOR
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.//
