- 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:
- 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
-- PF Prodelin 3.7 m AZ/EL type 1374-990 RX --
-- external high-frequency unit --
- 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 ---
--- Mark 1 defines the status of data carrier / f = 12 000 L ---
--- two other supporting data, which are present in the spectrum ---
--- quality analysis ---
--- locked carrier data transmission ---
