KIDDER Node Information

Location: Wolverley Park, 1 mile North of Kidderminster town centre, co-sited with GB7PZT BBS. Maps etc. can be found on G8PZT's Site
Purpose: User access and local / national / international linking
NGR / QRA: SO 829,781 IO82VJ
Height ASL: 46 metres
Propagation: The site is on a promontary intruding into the Stour valley, and the ground falls away on all sides except to the west, where it rises sharply. Kidderminster is surrounded on all sides by hills, so line of sight coverage is limited to 2 or 3 miles. However, the hills refract signals so overall propagation is good to the south, moderate to north and east and poor to the west.
Service Area: North Worcestershire and south-west Birmingham
In service since: 1988 as a 24h digipeater, converting later to a KA-node, then BPQ late 1990, and XRouter in early 2000
Operated by: Paula G8PZT @ GB7PZT
Reports / Contact: G8PZT
Data Hardware: 33MHz 486 PC, assorted Tiny2 and DL TNCs, RUH modem boards, hardware watchdog.
Software: XROUTER multi-protocol router / chat server / APRS digipeater etc.
