FreeCall

Using this VOIP program, you can call landline numbers in any country for FREE.

FreeCall is still a Freeware app but you only get 300 minutes a week.

To bypass this restriction:

Keep the setup.exe. Freecall's protection system is quite flawed, when the program announces you cannot use any more minutes = Uninstall and reinstall and it will reset your 300 minutes which only takes a moment.

A)You MUST make an account with the program when it loads up. Then when your logged in (it will say at the bottom: 'The client is logged on')

B)Go to the dial pad TAB, ignore the on screen buttons, at the bottom type in your number and remember you need to add country codes at the beginning - NO spaces in the number either.

C) And it does do all countries for free - i've used it from NZ to england, USA, Spain and Aussie and they used it back.

D) If it didn't work, you need to check your firewall settings etc, this is an obvious but a program like this needs full access.

Radio

Radio is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Early speculation that this required a medium of transport, called luminiferous aether, were found to be false. Information is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude or their frequency. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.

James Clerk Maxwell, a Scottish scientist, developed the theoretical basis for explaining electromagnetism. He predicted that electric and magnetic fields can couple together to form electromagnetic waves. Heinrich Hertz, a German scientist, is credited with being the first to produce and detect such waves at radio frequencies, in 1888, using a sparkgap transmitter in the Ultra High Frequency range.

In 1893, Nikola Tesla, in America, first demonstrated the feasibility of wireless communications. Guglielmo Marconi, an Italian inventor, was one of the first to develop commercial workable radio communication. It is supposed that he sent and received his first radio signal in Italy in 1895.
