- identification problem on 17.10.2010 -
I have done a detailed analysis of the entire HF string, which revealed a permanent source of interference in next sequence:
secondary radiant > primary radiant > LNB > coax cable > analyzer.For obvious reasons I will not be mentioned in detail the
source of interference but was associated with the noise temperature of the secondary radiant at elevation angle of only 3°.
The result of negating the source of interference was the status : occasional lock carrier is changed to stable lock,modest gain
growth in amplitude of 0.5 dB is increased by 0.6-0.8 dB / MER.If I would not reveal the source of interference, it would not
be recorded even a 5 sec video sequence because the carrier lock was unstable without any gain margin > (FEC=7/8) !
___ reception status of 17.10.2010 ___
within a span of 8 to 10 hours in the morning on 17.10.2010 am I have identified this signal status :
stable form of locking the carrier with oscillating gain growth from MER=0.5 to 2 dB above the treshold level MER = 6.5 dB
(FEC Protocol 7/8).About once for thirty minutes, the level of gain equal to the detection level and there is an immediate
increase in uncorrected Reed Solomon blocks in the order of tens , which subsequently resulted in the detection of short
time duration in units of seconds, not minutes. Lower level than bBER error = 6x10-3 I am not recorded in measurements.
Stable reception GlobeCast packet belongs in Central Europe in the category of SAT DX with a minimum recommended
diameter of 370 to 500 cm depending on the design and setup of the high frequency chain .
