The FCC granted the request for a period of 60 days. It noted that Hurricane Ida has caused significant damage, including disruption to electricity and communications services. The FCC concluded that granting the ARRL’s request was in the public interest. This was accomplished by adding a frequency shift keyer that used a. Many of those ready to assist have equipment that includes radio modems capable of higher data rates that are not currently permitted in the rules but are critical to sending hurricane relief communications including lists of needed and distributed supplies. Amateur Radio operators needed to modify their transmitters to allow for HF RTTY operation. The system is available over the Atlantic and Pacific including polar regions not served. The USCG also shares frequencies across multiple transmitters according to a schedule, rather like NAVTEX. The ARRL pointed out that the FCC had granted similar requests during hurricanes Laura, Maria and Dorian.ĪRRL said that trained amateur radio operators are prepared to assist federal state and local emergency management officials to assist with disaster relief communications. The main advantage of RTTY/SITOR is the reception of information over an entire ocean area.
#RTTY NEWS FREQUENCIES CODE#
The digital code transmitting must be one of the codes specified in the FCC’s rules, but an amateur radio transmitting a RTTY or data emission using one of the specified digital codes may use any technique whose technical characteristics have been publicly documented, such as CLOVER, G-TOR or PACTOR.ĪRRL requested the waiver for licensed amateur radio users directly involved in hurricane relief via HF amateur radio using PACTOR and VARA modems. Region 1 (Europe, Africa, Middle East & Northern Asia) band plan suggests 1838-1843 kHz.The FCC’s rules limit the symbol rate for high frequency (HF) amateur radioteletype (RTTY)/data transmissions to 300 bauds for frequencies below 28 MHz and 1,200 bauds in the 28 – 29.7 MHz band. (RTTY operation above 3600 KHz is not permitted in the USA).ġ60 meters – 1800 to 1810 kHz.
General, Advanced, Amateur Extra licensees: 1.800-2.000 MHz: CW, Phone, Image, RTTY/Data. The list below reflects the new privilages that Technician class Hams now have in BLUE TYPE. (USA stations are also allowed RTTY between 7100-7125 kHz).Ĩ0 meters – 3580 to 3600 kHz (JA 3520-3575 kHz), during contests 3570 (or lower)-3600 kHz. Technician licensees now have limited privileges below 30 MHz Notice: Effective Feb, 23, 2007. Note: It is illegal for USA stations to operate RTTY above 18110 KHz. For USA licensed frequencies, see and for USA band plan, see. For a detailed frequency band for IARU Region 2, see. When operating RTTY, be sure respect the band guards around the IBP/NCDXA beacon frequencies noted below.
Below are approximations of “normal” operating RTTY sub-bands world-wide. The HF RTTY sub-band boundaries are defined and limited by your license.
