When radio was invented over 100 years ago, Morse code was the only way to communicate. Voice transmission was invented later. In 2009 who is using Morse code? Amateur radio operators (Ham radio operators) use Morse code as a fun way to communicate. Sam Voron VK2BVS, 6O0A shows Somalia Amateur Radio students how to hold a Morse code key in Galkayo, Somalia. Hams (Helping All mankind and woMankind) radio operators get to know other individual radio operators by the sound of their Morse code in the same way that we recognise friends by the sound of their voice. People who love sending SMS mobile phone messages have the same enjoyment that Radio Hams feel when they communicate with their radio friends using Morse code.
One difference between SMS phone calls and Morse code radio conversations is that SMS mobile phone users pay for the SMS calls whereas local and worldwide ham radio Morse code (or voice or data) conversations are unlimited and free.
Each SMS phone call is charged a fee by commercial private business.
Morse code (and voice or data) on amateur radio is a worldwide humanitarian, scientific and experimental non-commercial friendship service operated by individual citizens who use the free radio airwaves to talk with ham radio enthusiasts in every country.
Ham radio conversations are free because they operate under the International regulations of the United Nations International Telecommunications Union to promote free worldwide friendship, disaster emergency communications assistance, scientific telecommunications research and technical training as well as in promoting human respect, education and worldwide understanding.
Another reason why local and worldwide Amateur radio calls are free is because ham radio operators do not operate their radio station for commercial or business purposes.
Ham radios (amateur radios) are used only to promote free worldwide friendship, human respect, education and worldwide understanding as well as to assist in emergency communications both locally and in other countries during disasters and in technical education and scientific research.
In 2009 Morse code is used by most people who have a mobile phone.
When an SMS message arrives you hear (dit dit dit) (daaa daaa) (dit dit dit) which is the International Morse code meaning SMS.
The following is a survey of all Morse code transmissions received in Sydney, Australia between 0 and 1.6 MHz (0 to 1600 kHz).
This Morse code survey will give an idea of who (apart from the amateur ham radio operators and the 900 MHz mobile radio SMS phone users as discussed above) is also using Morse code in the 21st century.
Surprisingly Morse code is found to be widely used in todays modern world doing its job silently and 24 hours a day.
Morse code in 2009 is used everyday on land, sea, air and space from helping aircraft pilots so that you and me depart and arrive at the airport safely through to scientific research work and more.

Morse code in the 21st century.
Radio Morse code from 0 to 1.6 MHz (0 to 1600 kHz).
Morse code on Low Frequency (LF), Long Wave (LW), Medium Wave (MW), Short Wave (SW) and VHF (Very High Frequency) radio.
CW Continuous Wave (radio wave) switched on and off is Morse code on radio.
A long one second signal is the Morse code dash and on radio sounds like Daaa.
A short eighth of a second signal is the Morse code dot and on radio sounds like Dit.
MCW is a modulated CW signal (made of a radio frequency carrier signal with an audio signal) and is Morse code that can be heard on an AM receiver.
CW is an unmodulated CW signal (made of a radio frequency carrier with no audio signal) and is Morse code that can be heard on any receiver that has a control to select SSB (Single Side Band) or LSB (Lower Side Band) or USB (Upper Side Band) or CW (Continuous Wave) or BFO (Beat Frequency Oscillator).
Before a Morse code radio call sign you often hear the letters “de” meaning “This is”
d (Daaa dit dit)
e (Dit)

Radio Morse code from 0 to 1.6 MHz (0 to 1600 kHz).
Non-Directional Radio Beacons, Non-Directional Beacons, NDB, Non Directional navigation Beacons, Long Wave beacons, Medium Wave beacons, Aviation radio beacons, Marine navigation radio beacons are 15 Watts to 3000 Watt radio transmitters using 160 kHz to 1.750 MHz with an antenna at a fixed and known location. On Long Wave most NDB in Australia operate from 200 to 490 MHz.
The future for Australian Non Directional Beacons NDB in the navigation plan for (backup) instrument approaches is to replace needed NDBs with new technology electronics and, if necessary more economical antennas.
From 2007 to 2009 a few NDBs that are not part of the Australian backup network of Non Directional Beacons NDB’s have been decommissioned (their operation has ended) when they approached the time to replace old equipment.
Australian Defence Force (ADF) Non Directional Beacons (NDB) is used by aircraft in flight to align their position relative to the runway position. NDB are used during poor visibility conditions and in good visibility conditions for training purposes. For example all aircraft using instrument approaches to prepare to land might commence their approaches to the airport runway from a distance of 15 nautical miles using navigation aids such as the Non Directional Beacon (NDB), Instrument Landing System (ILS) or Tactical Air Navigation System (TACAN).
The US Department of Defense Non Directional Beacon NDB radio class codes classify an NDB transmitter power of less than 50 Watts for use within 25 NM (Nautical miles), 50 to 2000 Watts for up to 50 NM and more than 2000 Watts for distances over 75 NM.
Those listening on these Long Wave frequencies for unusual and interesting radio signals have sometimes heard the low power 15 Watt NDB radio beacon signals from thousands of miles away especially during sunset, nighttime and sunrise.

0.135.7 to 0.137.8 MHz, 135.7 to 137.8 kHz New Australian 2000 metre Amateur Radio band. In January 2009 the Australian Radio Frequency Spectrum Plan was amended by the Australian Communications and Media Authority (ACMA) to create the first Low Frequency amateur radio band in Australia. This band was made available to radio amateurs worldwide in the International Telecommunications Union (ITU) World Radio Conference (WRC) in 2007.
From June 2009 the 135.7 kHz to 137.8 KHz band is available to all holders of the Australian Advanced Amateur radio license by applying to the Australian Communications and Media Authority (ACMA). By the end of 2009 or in 2010 the ACMA will allow use of this band to all holders of the Australian Advanced Amateur radio license without the need for Amateur Radio Operators to specially apply. Only Morse code (CW) and other narrow bandwidth emissions at a power level of 1 Watt (Equivalent Isotropic Radiated Power e.i.r.p) can be used.
Amateur Radio Stations in several other countries including New Zealand are transmitting in the 135.7 kHz to 137.8 KHz band. Regular listening on 135.7 to 137.8 kHz is now taking place in Sydney.

0.415 MHz to 0.526.5 MHz, 415 kHz to 526.5 kHz Proposed new World-wide 600 metre Amateur Radio band. In 2011 part of the NDB band might be shared with amateur radio stations.
In the 2011 International Telecommunications Union (ITU) World Administrative Radio Conference (WARC 2011) provisional agenda item 1.23 reads “to consider an allocation of about 15 kHz in parts of the 415 kHz to 526.5 kHz band to the amateur radio service on a secondary basis.”
Many NDBs in overseas countries especially in central Asia and Eastern Europe successfully operate between 526 KHz and 1600 KHz without problems from powerful Medium Wave broadcast stations who share this band.
In comparison to broadcast stations the lower powered Amateur Radio stations should also be able to successfully share frequency space in this new proposed 500 kHz 600 metre amateur radio band. Some countries such as Somalia and the USA have already permitted amateur radio operations on this band.
Morse code (CW) will be one of the modes of communications allowed on this new proposed Medium Frequency amateur radio band.

How far do NDB radio signals travel?
What is the power output of an NDB transmitter?
How many Watts is an NDB transmitter?
NDB transmitter.
NDB radio transmitters.
Most Non Directional Beacons NDB are used for short distances.
NDBs have low power levels of 15 Watts or medium power levels of 100 Watts or high power levels of 500 Watts and more.
Depending on location and antenna a 15 Watts NDB can provide a service coverage of 15 Nm (17 miles, 27 km) to 45 Nm Nautical miles (51 miles, 82 km) .
A 15 Watt NDB might be located so that aircraft will only hear a signal when 15 Nm (17 miles, 27 km) away.
Another 15 Watt beacon at a better location might be designed to be heard by aircraft 25 Nm (28 miles, 45 km).
A 100 Watt Non Directional Beacon NDB might be able to cover as little as 25 Nm (28 miles, 45 km) at one location and as much as 100 Nm (115 miles, 185 km) at a better location.
A 1000 Watt beacon might be needed at one location to cover 85 Nm (97 miles, 156 km) and might be used in another location to cover 150 miles (172 miles, 276 km).
Before takeoff and before landing an aircraft can hear voice aircraft terminal information on some NDBs. Where a voice service is used it includes weather information, general airport status and runway information.
Other NDB are used only for Direction Finding DF.
NDB are used as a matter of routine in all aviation.
For the listener at home it is interesting to hear radio signals travelling hundreds or thousands of miles more than its intended broadcasting area.
At night these Non Directional Beacons NDB on 200 to 490 kHz can cover thousands of miles.
What is the coverage of Non Directional Beacons NDBs at midday?
The minimum transmission range of Non Directional Radio Beacons is near midday on the 200 to 490 kHz (Long wave and Medium Wave radio bands).
At midday more transmission range is possible at winter (compared to midday in Summer).
More transmission range might also be possible in the sunspot minimum of the 11 year solar cycle compared to the years of sunspot maximum (expected in 3 to 4 years).
In 2009 the 11 year solar cycle is at minimum Sunspots and June to July is winter in Australia.
The following observations of Non Directional Beacons NDB are made from Roseville in Sydney, Australia around midday winter during the Solar minimum sunspot period of 2009.
Listening to Long Wave Radio in Sydney near midday resulted in hearing the following NDB.
Non Directional Radio Beacons that have been received around Midday are listed starting with those transmitters that are near Sydney, Australia.
The distance of the radio transmitter from Sydney is shown in kilometres and miles.
