"The first observations of cosmic radio emission were made by the American
engineer Karl G. Jansky in 1932, while studying thunderstorm radio disturbances at a frequency of 20.5 MHz (14.6 m). He discovered radio emission of unknown origin, which varied within a 24-hour period. Later he identified the source of this radiation to be in the direction of the centre of our Galaxy. From: http://encyclozine.com/science/astronomy/radio I understand that the frequency "varied within a 24-hour period". It is the "diurnal effect". And what about the 365 days period (annual effect)?

S* It is not the frequency that changed, but the intensity. And not a 24 hour period, but 23 hours, 56 minutes, thus proving that the noise was not generated or varied by the earth's rotation. http://www.enotes.com/karl-jansky-reference/karl-jansky |

So if the distant transmitter is an FM broadcast station you will hear a brief burst of audio from that station. If you are listening on an amateur radio band you will hear a brief exchange between two stations either in audio (SSB probably) or in Morse code (maybe high speed) or in a data transmission format. No sounds of the universe, just ordinary radio sounds but over an unusually long distance and a little spooky cos of the doppler and ionization distortion. depending upon the frequency in use and the 'strength' of the ionization caused by the meteor the duration of the reflection path can be long enough for a complete real time over-over QSO to take place where callsigns and signal strength reports can be exchanged between the two amateur radio stations. The 50MHz and 144MHz allocations are good places to listen for this. |

"His" transmitter "produced" many frequencies. But Karl G. Jansky was the pioneer in Radio Astronomy. Now are the spacecrafts. They use the two frequencies. I have found the link: http://chaos.swarthmore.edu/courses/...er_Anomaly.pdf ""It is also possible to infer the position in the sky of a spacecraft from the Doppler data. This is accomplished by examining the diurnal variation imparted to the Doppler shift by the Earth's rotation. As the ground station rotates underneath a spacecraft, the Doppler shift is modulated by a sinusoid." Probably in this paper is also the answer for my question: "And what about the 365 days period (annual effect)? Unfortunately I am not an expert in radio. Do you know the answer? S* |

He loves to ask questio0ns, get answers, and then tell all of us that any science newer than 100 or 150 years old is incorrect. Even when the scientist in question changed his original theory due to newer and better evidence. It will happen. Just wait a bit. tom K0TAR |

It seems to me that today's astronomers are wrong because in physics are still null result. So I am looking for the result from communication with the spacecraft. S* |

Even when the scientist in question changed his original theory due to newer and better evidence. In each textbook is wrote that we can detect the angular motion of the Earth but the orbital not. It will happen. Just wait a bit. To you know the best evidence (the frequency variation from the spacecraft in the annual period)? S* |

He doesn't like new results. Ever. And if you provide evidence that he doesn't like, such as spacecraft comm results that will likely not be what he likes, he will dispute it and point back to the deprecated experiments. It never ends. He is the ultimate troll. Ok, the ultimate troll isn't him, it's another that hasn't shown up here lately, but he's very close. tom K0TAR |

In today's physics is opinion that we can detect the angular motion (Sagnac effect) but it is impossible to detect the linear motion. Who and when deprecated the famous null result? S* |
