| 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. | ||||||||||
