It's a small world

 

It's a small world

Aeroplane, people, shaking hands … and it’s getting smaller every day. Modern speed of travel and communication make this a rapidly-reducing globe.

And more people can listen to more people, people who liove thousands of miles away, by short-wave.

That’s a good thing. Knowledge can lead to friendship and understanding.

 

Four musicians of various nationalities

 

But your short-wave listening must be clear and as free from interference as modern know-how can make it. There’s no pleasure in mangled music, no understanding from a blurred message, You must receive your small world with the best possible clarity and quality.

There are 3,000 frequencies registered for short-wave broadcasting all over your small world. The most widely used international band lies between 16 and 49 metres on the dial.

 

It's a small world

 

Philips Quality Short Wave receivers make today’s world smaller then ever before by bringing far distant stations into your home as clearly and closely as if you were listening to your local station – just a few thousand miles away. In a world as small as your world that’s right next door with Philips Quality Short Wave.

 

Far away places

… await your pleasure on the short-wave bands where the world truly entertains the world. Short-wave listening brings you a fascinating new source of entertainment and interest.

Listen to your favourite style of music from the lands of its origin – somewhere in your small world you’ll find it whether it’s ‘rock-and-roll’ or ‘The King’, Calypso or Chopin, ‘blues’ or Bach. If it’s there, you’ll find it. And new sounds too, strange intriguing sounds from far away in your small world. You can listen to history in the making as important world events take place, news programmes, the amateurs carrying on their inter-global conversations. All round the clock thousands of stations are queueing up to entertain you. The sounds of earth are at your service – capture on a tuning scale, waiting for the touch of your fingers.

It’s a small world but it is still full of wonders. You can hear them in your home as never before with Philips Quality Short Wave.

 

When the world was a much bigger place…

 

… Philips were experimenting, working and researching to find ways to make it smaller by short-wave. In more than 160 countries all over five continents the name Philips has become a byword for reliability and quality in lands where clear, reliable short-wave communication is not just an entertainment but a necessity of life.

Now Philips bring to your home the results of that experiment and research towards absolute perfection in short-wave quality. Philips offer a choice of top-quality short-wave receivers representing the very best available in the world.

These are not merely radio sets with a short-wave band. Philips Quality Short Wave is scientifically developed to give a high quality performance. And you can control the quality of every sound you hear. This is specially important on short-wave where the transmitters jostle each other for your attention – sometimes nearly overlap. Philips ‘slow-motion’ tuning separates the stations and brings them into your home as you require them. Philips tone-control sorts out the high sounds from the low throughout the frequency scale and reduces atmospheric interference to a minimum.

 

All of which means that you can now hear more entertainment from more places all over your small world more clearly and with better sound quality then ever before!

Ask your dealer to demonstrate Quality Short Wave by Philips – the friend of the family.

 

A short note on short wave

 

Wavelength diagram

DIAGRAM 1

Short waves are so named because they are more closely bunched than long waves (see diag. 1). When the wave has travelled from the datum line through a maximum and a minimum and returned to the datum line, it has completed 1 cycle. The number of cycles per second is known as frequency. Since the S.W. transmissions are more closely bunched they are at a higher frequency (above 1,600,000 cycles per second or 1,600 Kc/s). The S.W. band is usually referred to in terms of wavelength in metres rather than frequency in Kc/s, and this simple formula gives the relationship:

Frequency (Kc/s) × Wavelength (metres) = 300,000

Short-wave transmissions rely on the phenomena of bouncing off the ionosphere (see diag. 2) to provide reception over great distances. The ionosphere is continually changing and its density is affected by the amount of activity on the surface of the sun. This activity is known as the ‘sun spot cycle’. In general, when activity is low, the intensity of the ultra-violet rays reaching the ionosphere is also low, and the ionosphere is capable of reflecting the lower frequencies better than the higher frequencies. The best reception under these conditions is obtained on the higher metre bands.

During 1964/65 solar activity will be low and the best reception is likely to be obtained on the 25, 31, 41 metre bands during the day and the 31, 41, 49 metre bands during the hours of darkness. After 1965 it is predicted that the amount of solar activity will increase as a new sun spot cycle commences. In general the best time to listen to S.W. international transmissions is during the evening and night hours.

Since S.W. transmissions rely on the bouncing of radio waves from the continually changing ionosphere the transmitters are beamed to cover particular predetermined areas, and the frequencies of the transmitters are changed to allow for changes in the ionosphere. A world map and the chart (diag. 3) will therefore be a useful guide in helping you to explore this fascinating new world.
