Japan IRLP Nodes at-a-glance


Node 8200 was the first IRLP node in Asia. Node 8200 operates on the JR1VI repeater licensed to the Tokyo Intl. Amateur Radio Association. The JR1VI repeater uses a Diamond X510 groundplane (8.3db gain).

The brain of the node is an IBM Aptiva JDA (133 mhz., 1.6 GB HDD), running Linux Red Hat 6.2 connected to a 100Mbps NTT B FLETS fiber optic circuit. Power for most of the node/repeater computer and communications equipment is routed through uninterruptible power supplies for emergencies.
