Data is subject to change.  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 Hotbird 13G satellite at 13° E since mid-July 2024.  Readings are taken every five minutes, and X-axis times are in UTC.  The four outputs are used to feed the three main receivers.  Output one from the LNB is used for BAS and 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.  Outout 2 is available for HVS-3 tests, and output for general tests.

Multiple receive PCs are fed from the Traffic LAN ports of the Ayecka SR 1 IP BAS/HVS-1receiver on a private LAN (192.168.10.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 #1 receiver takes both BAS and HVS-1.  HVS-1 is received and processed by PC Kiruna, and received by PC Lund, processed by PC Penguin...

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.
