Shannon Radio

Broadcast from Shannon VOLMET

Shannon (Air) Radio , also known as Shannon Aeradio or Shanwick Radio , is the most important ground station for European transatlantic air traffic in the Irish community of Newmarket-on-Fergus, County Clare . The station operated by the Irish Aviation Authority (officially North Atlantic Communications Center ) broadcasts weather and warning messages for its flight information area over the North Atlantic ( ICAO code : EIAA) and receives and confirms inquiries from pilots via shortwave and VHF radio, and forwards messages from Air traffic control to aircraft.

history

Shannon Aeradio was established in 1936 to communicate with flying boats that crossed the Atlantic. The flights usually lasted up to 18 hours and started in Foynes , Ireland and landed in Botwood , Newfoundland . Communication was carried out in Morse code.

The ground radio station initially consisted of the spatially separated stations in Ballygirreen ⊙ ( rx ), Urlanmore ⊙ ( tx ), Foynes (land connection) and Rineanna or Shannon (control unit). Medium wave transmitters were mainly used for the transmission of meteorological data.

After the Second World War, radiotelephony was introduced for communication with aircraft and RTTY telex for transmission in the fixed aviation radio service .

Until the early 1950s, Shannon VOLMET broadcast aviation weather for Shannon, Dublin, Prestwick, Hurn (Bournemouth), Amsterdam and Brussels airports in Morse code ; since 1960 only radiotelephone has been used.

Aeronautical radio

Today, the shortwave frequencies 5505 kHz and 8957 kHz (all day), 3413 kHz (at night) and 13264 kHz (during the day) are used for the VOLMET service . Information about Frankfurt am Main Airport comes around the hour, half an hour and 10 minutes before the hour.

Shannon Radio working frequencies:

Family "A" 3,016 kHz 5,598 kHz 8.906 kHz 13,306 kHz
Family "B" 2,899 kHz 5,616 kHz 8,864 kHz 13,291 kHz
Family "C" 2,872 kHz 5,649 kHz 8,879 kHz 11,336 kHz

Family "I" 2,890 kHz 6,595 kHz
Family "J" 3,446 kHz 6,547 kHz
VHF 127.9 MHz 124.175 MHz

Radio data transmission via satellite has been increasing since 2001 . Currently (2012) an estimated 40 percent of the aircraft assigned to the Shanwick Oceanic Control Area use the Automatic Dependent Surveillance (ADS) and Controller / Pilot Data Link Communications ( CPDLC ) systems for their communication with the ground. Nonetheless, radio communication via HF is also increasing: In 2007 the station recorded 414,570 contacts with 1,029,335 voice messages; The peak day so far has been June 23, 2016 with contacts to 1,772 aircraft.
