39.0°E Hellas Sat 3

    • Offizieller Beitrag

    I can not be sure but this may be Hellas Sat 3 39E. It is between Turksat 42E and Athena Fidus 37.8E. There are 4 or more 800kHz wide data signals and one 300kHz wide. There is a carrier on 18717.8MHz and possibly 2 other weak carriers nearby. The weak ones could be spurii.


    Polarisation is circular but received on a linear feed. No other signals visible between 18.5 and 20.5GHz
    A peak was visible on Crazyscan but the individual signals were not separable or lockable.


    The frequency accuracy is +/-100kHz
    1.2m Offset

    Circular left spectrum. (19575 looks like an home-made problem - appears on several positions...)

    Nothing here on that frequency.
