 HIGH SEAS RADIO-TELEX BROADCASTS
HF NBDP MSI   HIGH FREQUENCY NARROW-BAND-DIRECT-PRINTING MARITIME SAFETY INFORMATION
       Class : Maritime Broadcast  (Scheduled).  Mode : FSK (SITOR-B FSK 100/170).  Band : SW (SHORTWAVE). 
       Content : Marine weather forecasts, warnings & NOTSHIP (notices to shipping). May also include weather or ice observations.
       International NBDP MSI = 4.210 , 6.314 , 8.416.5 , 12.579 , 16.806.5 , 19.680.5 , 22.376 , 26.100.5 MHz
       Frequencies are centre frequencies for receivers in FSK mode.  FSK mode is recommended as it allows for narrow bandwidth.
       For USB mode, subtract 1.7 kHz and use a wider bandwidth.  Expect more interference in USB mode vs. FSK mode.
       All broadcasts are made in English (EE) unless otherwise noted by an entry in the Lang column :
       CC = Chinese    RR = Russian  
       GR = Greek    SS = Spanish  
       PP = Portuguese    TT = Turkish  
       # = One hour earlier when DT in effect.  Cont = Continuous
HF NAVDAT HIGH FREQUENCY NAVIGATIONAL DATA
       Class : Maritime Broadcast  (Scheduled).  Mode : 10 kHz DATA (OFDM 47.4 kBaud).
       Content : Under development. Proposed service not yet implemented.
       Assignments : 3-minute time slot every hour on a standard shared frequency.
       HF NAVDAT = 4.226 , 6.337.5 , 8.443 , 12.663.5 , 16.909.5 , 22.450.5 MHz
       Tuning in this mode requires a receiver with 12 kHz bandwidth capability.
