8957 lady voice in USB from Ireland Shannon Volmet 

VOLMET (French origin vol (flight) and météo (weather report)), or meteorological information for aircraft in flight, is a worldwide network of radio stations that broadcast TAF, SIGMET and METAR reports on shortwave frequencies, and in some countries on VHF too. Reports are sent in upper sideband mode, using automated voice transmissions.

Pilots on international routes, such as North Atlantic Tracks, use these transmissions to avoid storms and turbulence, and to determine which procedures to use for descent, approach, and landing.

The VOLMET network divides the world into specific regions, and individual VOLMET stations in each region broadcast weather reports for specific groups of air terminals in their region at specific times, coordinating their transmission schedules so as not to interfere with one another. Schedules are determined in intervals of five minutes, with one VOLMET station in each region broadcasting reports for a fixed list of cities in each interval. These schedules repeat every hour.

An aircraft in flight can obtain by VOLMET the Aviation routine weather reports (METAR) of specific airports.

Due to changing propagation conditions, VOLMET messages are sent on three different frequencies, in USB radiotelephony mode with a power of 5 kW. The main frequency is 5505 kHz, the other frequencies change according to the time. from 12 p.m. to 6 p.m. on 5505kHz 8957kHz and 13264kHz, then from 6 p.m. to 12 p.m. on 3413kHz 5505kHz and 8957kHz

From five to five minutes you hear the forecasts from half a dozen European airports, twice an hour, on the hour and a half:

H + 00 and H +30 Brussels, Hamburg, Frankfurt, Cologne, Düsseldorf, Munich.

H+05 and H+35 Shannon, Prestwick, London Heathrow, Amsterdam, Manchester, London Gatwick

H+10 and H+40 Copenhagen, Stockholm, Gothenburg, Bergen, Oslo, Helsinki, Dublin, Barcelona

H + 15 and H +45 Madrid, Lisbon, Santa Maria, Paris Orly, Paris CDG, Lyon.

H+20 and H+50 Rome, Milan, Zurich, Geneva, Turin, Keflavik.

Here are some guidelines for understanding the weather report:

Data transmitted:

- The station name

- check-in time

- The direction and strength of the wind

- The visibility

- The present time

- The state of the clouds

- Temperature

- Dew point temperature

- Atmospheric pressure (QNH)

- An indicator is sometimes transmitted "NOSIG" (NO SIGnificant change) It indicates that there will be no significant changes in weather conditions within the next 2 hours. The other messages are - GRADU: Gradually. - INTER: Intermittently. - RAPID: Quickly. - TEMPO: Temporarily. - TREND: Trend.

Another indicator can be used "CAVOK" it replaces the present weather visibility and cloud condition part of the message when the following meteorological conditions occur simultaneously:

- Visibility > 10 km

- No clouds below 1500 meters

- No significant weather phenomena

Station checks by QSL, address is Shannon Aeradio, North Atlantic Communications, Ballygirreen, Newmarket-on-Fergus, Co Clare, IRELAND or qsl@iaa.ei

Other VOLMET International stations:

For Africa: Brazzaville on 10057 kHz

For the North Atlantic: Gander (Canada) and New York (USA)

North and Central Asia: Moscow, Novosibirsk, Khabarovsk and Tashkent (Usbekistan).

Southeast Asia: Bankok (Thailand) Karachi (Pakistan, Bombay (India) and Singapore.

Pacific: Auckland (New Zealand) Honolulu (USA) Hong Kong (China) Tokyo (Japan).

South America: Ezeiza (Argentina)

With the ever increasing availability of SATCOM and data link equipment such as ACARS, the reliance on VOLMET is diminishing. Nevertheless, it is expected that VOLMET stations will continue to broadcast in-flight weather information for years to come.

Letter beacon



Letter beacons are radio transmissions of uncertain origin and unknown purpose, consisting of only a single repeating Morse code letter. They have been classified into a number of groups according to transmission code and frequency, and it is supposed that the source for most of them is Russia and began during the Soviet Union.

(Some beacons sending Morse code letters are well known directional or non-directional beacons for radio navigation. These are not discussed in this article.)

Letter beacons have been referred to as:

  • SLB, or "Single Letter Beacons"
  • SLHFB, or "Single Letter High Frequency Beacons"
  • SLHFM, or "Single Letter High Frequency Markers"
  • Cluster beacons
  • MX — an ENIGMA[NOTES 1] and ENIGMA-2000[NOTES 2] designation.


MWARA is the term for Major World Air Route Areas, which support HF Radio communications to aircraft outside of VHF range.

All frequencies listed are in KHz (USB mode). Groups of frequencies in one region are often referred to as 'families'.

For worldwide listing by families with maps, see the Atlantic page for the Atlantic routes, and for the Pacific, polar and Mexican routes see the Pacific, Polar and Mexican page from the Collins website. These pages also contain charts with up to date LDOC (Long Distance Operational Control) frequencies




Types of radio emissions


he International Telecommunication Union uses an internationally agreed system for classifying radio frequency signals. Each type of radio emission is classified according to its bandwidth, method of modulation, nature of the modulating signal, and type of information transmitted on the carrier signal. It is based on characteristics of the signal, not on the transmitter used.

An emission designation is of the form BBBB 123 45, where BBBB is the bandwidth of the signal, 1 is a letter indicating the type of modulation used of the main carrier (not including any subcarriers which is why FM stereo is F8E and not D8E), 2 is a digit representing the type of modulating signal again of the main carrier, 3 is a letter corresponding to the type of information transmitted, 4 is a letter indicating the practical details of the transmitted information, and 5 is a letter that represents the method of multiplexing. The 4 and 5 fields are optional.

This designation system was agreed at the 1979 World Administrative Radio Conference (WARC 79), and gave rise to the Radio Regulations that came into force on 1 January 1982. A similar designation system had been in use under prior Radio Regulations.

NAVTEX

NAVTEX (NAVigational TEleX), sometimes styled Navtex or NavTex,[1] is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent maritime safety information (MSI) to ships.

NAVTEX was developed to provide a low-cost, simple, and automated means of receiving this information aboard ships at sea within approximately 370 km (200 nautical miles) off-shore.

There are no user fees associated with receiving NAVTEX broadcasts, as the transmissions are typically transmitted from the National Weather Authority (Italy) or Navy or Coast Guard (as in the US) or national navigation authority (Canada).

Where the messages contain weather forecasts, an abbreviated format very similar to the shipping forecast is used.

Pinneberg transmitter

The Pinneberg transmission system is a telecommunications system in Pinneberg . It is owned by the German Weather Service . The predecessor until the 1990s was the Quickborn radio station .

The transmitter operates various transmitters. DDH47 broadcasts on the 147.3 kHz frequency , which is just outside the longwave broadcast range (148.5 kHz – 283.5 kHz). It sends weather reports, mainly for seafaring, with a transmission power of 10 kilowatts via RTTY at 50  baud . The broadcasting of meteorological information by the German Weather Service via its RTTY transmitters DDH7, DDK2, DDK9 and DDH8, DDH9 and DDH47 ( Seewetterdienst ) serves exclusively to ensure safety at sea within the framework of the international SOLAS agreement.

A T- antenna suspended from two grounded, guyed steel truss masts , each 99 meters high, is used as the transmitting antenna.

PIRATE radios frequencies and bands

On medium wave the frequency range 1600-1700 khz is commonly used.

On shortwave these specific parts of the spectrum are used:

source: http://www.freewebs.com/ukdxer/

76 metres: 3900-3945/4010-4100 kHz:

This is popular with European pirates, especially in the evenings when skip is longer, and during the day in winter months. A regular is Laser Hot Hits on 4026 kHz.

52 metres: 5800-5840 kHz:

European pirates can also be found here, overspill from 48 metres. Not so popular recently.

48 metres: 6200-6400 kHz:

This is a prime area for the Euro-pirates, especially at weekends.

47-42 metres: 6400-6900 kHz:

Other pockets of pirate activity occur in this area … in particular between 6400 & 6450, 6500 & 6600 and around 6700-6750. Stations often pop up wherever they find a clear frequency

43 metres: 6900-7000 kHz:

This area tends be mostly used by North American pirates, but is growing in popularity among Euro-pirates.

39 metres: 7500-7700 kHz:

Unreliable propagation means this band isn’t widely used but some Euro-pirates can be heard here.

Others also can be heard on higher shortwave frequencies … such as 9290, 12256, 15070 among others
