- on 25th April 2009 I made the first measurements of the spectrum from satellite Chinasat 9 to 92.2 ° E in the KU band
for the purpose of identifying the data carrier transmission for f = 12 000 MHz spectrum in a circular wave vector L.
Place of reception was city of Lučenec-central Slovakia with the following satellite set:

  1. Prodelin center antenna with a diameter of 3.7 meters at fixed attached / AZ/EL type 1374-990 RX /

     2.  External high-frequency unit, which was formed: SMW WDL Digital Type E, mechanical polarizer Hirschmann
          CSP 1210 C , depolarizer SMW XD-12
    

     3.  Depolarizer SMW XD-12

- followed by a detailed analysis of the spectrum with the L wave vector expressing the quality of income data for the
carrier frequency f = 12 000 MHz, which was broadcast in compression MPEG-2 / format DVB-S

                                        ---  range of frequencies from 11 840 to 12 000 MHz ---
