    Default Scanners, Pagers & Satellites?


    After browsing this section, I never realised that I could use my scanner and pc to decode all those beeps from various frequencies.

    Have been reading etc and am going to be 'messing around' with the software tonight.

    Has anyone got any good links for newbies in this decoding field.

    Would like to view weather satellites if possible?

    Have a Yupi, so it should be able to receive the correct frequencies.?

    can receive pager messages now with the software cosmicma recommended.....does anyone know what frequencies weather satellites work on.?

    here is a bit of information on weather satalites i have found and as soon as i get a decent antenna i will have a bash at doing something with em myself

    Receivers and Antennas for Weather Satellites

    The polar orbiting satellites (NOAA, Meteor) transmit their APT pictures in the 137 MHz band [1], while the geostationary
    satellites (Meteosat, GOES) can be found at 1.7 GHz. It is common practice to use a converter for the microwave frequency
    with an output at 137 MHz. This way one receiver can be used for both satellite systems.
    Equipment is sold by several commercial companies, but can also be homemade [2-6].
    The tramsmission frequencies are:

    Satellite Frequency/MHz Polatization
    NOAA 137.500, 137.620 rhc
    Meteor 137.850, 137.300 rhc
    Resurs 137.850, 137.300 rhc
    Sich 137.400 rhc
    Okean 137.400 rhc
    geostationary 1691.0; 1694.5 linear

    The RF carrrier is frequency modulated with a deviation of +/- 17 kHz (NOAA). While the Meteor satellites transmit with a
    similar deviation, the Sich and Okean satellites have less FM deviation. Meteosat uses an FM deviation of 9 kHz.
    A turnstile (137 MHz cross dipole for right-hand circular polarization with a reflector) looking straight up is an effective and
    simple antenna for the polar orbiting satellites [7, 8]. A more sophisticated set-up uses a high gain rhc-polarized antenna and
    an azimuth/elevation rotor system. For the geostationary satellites a Yagi-Uda antenna with 30 elements [9] as well as a
    parabolic dish [7] can be used.

    To avoid interference the receiver and especially the antenna should be located away from the computer. Furthermore the
    computer must be sufficiently shielded.
