METEOROLOGICAL RADIOTELETYPE BROADCASTS
RATT	METEOROLOGICAL FIXED BROADCAST (MX)
	Class : Meteorological Broadcast.  Mode : FSK (RTTY).  Band : SW (SHORTWAVE).
	Content : Weather & Ice Bulletins.
	H + = minutes past the hour.  Cont = Continuous.  O/R = On Request Only.
	1700 - 27500 kHz  (1.7 - 27.5 MHz).
	Frequencies shown are tone/mark centre frequencies for receivers in FSK mode. If using USB mode, subtract 1.7 kHz.
	The standard meteorological RTTY parameters are 75 baud with 850 Hz shift, but will vary.
	All broadcasts are in English (EE) unless otherwise noted by an entry in the Lang column :
	GG/EE = German & English
TLX	METEOROLOGICAL FIXED BROADCAST (MX)
	Class : Meteorological Broadcast.  Mode : FSK (FEC - SITOR-B).  Band : SW (SHORTWAVE).
	Content : Weather & Ice Bulletins.
	H + = minutes past the hour.  Cont = Continuous.  O/R = On Request Only.
	1700 - 27500 kHz  (1.7 - 27.5 MHz).
	Frequencies shown are centre frequencies for receivers in FSK mode.  FSK mode is recommended as it allows for narrow bandwidth.
	For USB mode, subtract 1.8 kHz and use a wider bandwidth.  Expect more interference in USB mode vs. FSK mode.
	All broadcasts are in English (EE) unless otherwise noted by an entry in the Lang column.
