    This is short extract from a last week's programme.

    It is interesting, that exactly on the 16th of November (but in 1924) they started RADIO broadcasting in my city, which was the capital of Ukraine then....

    On this weekend World Service also broadcasted this programme:

    Hi Alex S


    It also can be cosidered as a wonderful sense of being in touch of the world. We can listen to the voice of people. However we have'nt got pictures there. Only audio. No Video.

    I listen to the BBC NEWS brodcasted through Local Radios.

    I listen to the BBC NEWS brodcasted through Local Radios.   I guess you listen using Ultra Short Waves. On those waves (and frequencies) you really can receive only nearby stations. Have you ever saw Short Wave receivers? You are not very young - you may remember... Do you live in Colombo? By the way, have you ever heard about Sir Arthur C. Clarke?

    We can listen to the voice of people the voices, to the music, to the singing, to the... sounds! Look back - try to find my thread "AUDIO vs VIDEO" and read what I wrote there.... I'm going to return to the discussion there some day...

    However we have'nt got pictures there. Only audio. No Video   Do you know the difference between TV broadcasting and Radio broadcasting?

    Hi Alex

    I can go to Colombo within one and half hours. It is about 55 km away from where I live.
    Sir Arthur C Clarke lived in Sri Lanka. His office " Arthur C Clarke centre" was adjacent to the Faculty of Engineering at the Unversity of Moratuwa. He was the (emeritus) Chancellor of that University. His name was very popular in the world.
    He died in 2008. I too studied Diploma in Civil Engineering from the Univesity of Moratuwa those days.

    Radio only transmitts audio, while, TV, transmitts audio and video.

    Best regards

    Well, it is a PHILOSOPHICAL issue! smiley - biggrin You may say that PAPER "transmits" only TEXT, while BOOK "transmits" both PICTURES and TEXT, but is it really so? For the paper it "doesn/t matter" what you print on it - picture or text. It depends how we PRESENT and INTERPRET information! The same is with the ELECTROMAGNETIC WAVES - for them it doesn't matter what signal to carry - audio or video. They "don't know" it. It depends how we PROCESS and present the signal.... TV virtually is the same "RADIO" which is presenting some part of a signal as pictures.... Especially now, when all signals are mostly digital and it is possible to "listen" to the video signals and watch audio waves - I often use it in my videos - I hope you have seen it....

    It is great, that you heard about Arthur Clarke. Do you know that it was his idea to put a satellite into a geostationary orbit and transmit signals using it? Now we are watching thousands TV channels from all over the World using such satellites. We may point our dishes to just one point in the sky! I am listening to the BBC World Service from the Hot Bird satellite. I also can watch TV programmes of course... using the SAME receiver! The frequency of the basic signal is so high (GigaHertz), that it can transmit lots of audio channels on the same carrier!

    Hi, Nimsara!

    It seems you are online. (At least I see two those asterisks smiley - biggrin)

    So - RADIO as a "way of trasmitting information" may transmit everything - audio, video, pictures....

    But RADIO as a device (Radio Set or Receiver) is a tool for coverting electromagnetic signals into AUDIO (sound) vaves! It is interesting, that the light which we see is absolutely the same electromagnetic waves, that uses radio as a "transmitter" - the only difference is.... FREQUENCY!

    But to hear information we need waves in the AIR! Something completely different!

    There is also one amazing feature of the radio RECEIVER - TUNING! And especially in the Short Wave receiver! We do not have this feature neighter in the Internet, noe even in the Satellite Receivers!
