This data is taken from PCs fed
by Ayecka SR1 IP
and TBS receivers. The RF
feeds are shown in red. The antenna is
pointed to the EUTELSAT 10A satellite at 10°
E, to change to EUTELSAT
10B in July-2023. Readings are taken every five minutes, and X-axis times are in UTC. From
late September 2017 the main RF feed has been changed to have a 4-way splitter -
there's enough signal to allow this, otherwise an in-line amplifier could have
been added. The four outputs are used to feed the three main
receivers. Output two from the LNB is used for BAS/HVS-1, three is used
for HVS-2, and output four
allows direct access to the LNB for polarisation tests, which would otherwise
interfere with routine reception.
Multiple receive PCs are fed from the Traffic LAN ports of the Ayecka SR 1 IP receivers on
a private LANs (192.168.10.x/20.x) via GS605 Netgear
switches, with 1 Gbps network cards added to
the receiver PCs. An Edimax
USB2.0-Ethernet adapter is an alternative because of the need to use
USB or better
drivers. Ayecka SR1 #2 receiver takes both BAS and HVS-1. BAS
is received by PC Oslo. HVS-1 is received and
processed by PC Kiruna, and received by PC Lund, processed by PC Penguin.. From Feb-2017 PC Lund monitors
HVS-1 & HVS-2 with a single-cable TBS6903
dual-tuner PCIe card, but this arrangement had to be abandoned when HVS-2
was switched to a transponder with a different polarisation in late 2022..
The Ayecka SR1 Management ports are connected to the
existing 192.168.0.x house LAN, through
which management access is possible from any local PC.
