Voices from the Sky, Monitoring the ISS

This is a video I took Februray 21, 2008. Eyharts FX0STD a French astronaut aboard the ISS has been in contact with a French school with the help of some ham operators F6KFA. Since I was in southern Germany can not hear the sound of the ISS. I was just using my Yaesu VR500 receiver equipped with a Nagoya NA-636 antenna. Sorry for the bad quality, I took this using my cell phone. Rabbit Mathilda, a Korean artist experimnental includes audio of this videothe theme "Boarding Pass", visit their MySpace www.myspace.com. J'Ai prisons cette video 21/02/2008 him. With the help of amateur radio club F6KFA FX0STD Eyharts, French astronaut aboard the ISS responded to questions from elementary school student. I was in Southern Germany at the time ou J'Ai this video PRIT, CE fait the understanding that in the ISS. The EST receiver using a simple Yaesu VR-500 with an antenna Nagoya NA-636.

A scanner is a radio receiver that can automatically detect or scan, two or more discrete frequencies, stopping when it finds a signal A scanner is a radio receiver that can automatically detect or scantwo or more discrete frequencies, stopping when it finds a signal on one of them, and then continuing scanning when that frequency is silent. Many scanners cover the non-band radio propagation between 30 and 951 MHz with FM, but there are models that cover most of the radio spectrum and use other modulation types. Early explorers were slow, cumbersome and expensive. Today, modern microprocessors have enabled scanners to store thousands of channels and monitor hundreds of channels per second.Newer models can monitor radio systems with shared resources and decode APCO-P25 digital transmissions. The two models of laptop and desktop are available. Scanners are often used to monitor police, fire and emergency medical services. Scanners developed from earlier tunable and fixed frequency radios that received one frequency at a time. The non-distribution systems of radio, such as those used by public safety agencies do not transmit continuously. With a fixed radius on a single frequency, much time can pass...
