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.  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 purely for HVS-1, three is used for HVS-1 and HVS-2 in a single-cable, dual-tuner arrangement, and output four allows direct access to the LNB for polarisation tests, which would otherwise interfere with routine reception.

Two 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 better drivers.  PC Penguin is fed from a TBS5927 USB 2.0 box.  Ayecka SR1 #2 receiver takes only HVS, received and processed by PC Kiruna.  From Feb-2017 PC Lund monitors HVS-1 & HVS-2 with a single-cable TBS6903 dual-tuner PCIe card.

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.
