The beacon is now operational at a new location, IO81VC73 with beacon keeper now G3TCT.  The NoV was issued by Ofcom on 20 June 2016. The beacon started operation on 26 July 2016.

Beacon parameters:-

Frequency

1296.870MHz.  The exciter is not GPS-locked and may be up to 1kHz off frequency. 

NEW  As from 17 Feb 2017, the exciter is based on an Arduino-controlled ADF4351 synthesiser with a 10MHz reference and should now be within 100Hz.

Mode F1  (1K50F1AAN)
ERP 20dBW east and 16dBW north, horizontal polarisation
Antenna Wimo flat plate PA-23R-16.  Power is split between Wimo and 47cm dish pointing due north.  Maximum radiation from the system is at 090 degrees.
Height ASL 218m
Antenna height AGL 15m
Times of operation

From 21 Sept 2017, 0800 to 1700UTC

The beacon is at a site that is solar and wind powered only, and also supports 2m and 70cm repeaters. In order to keep within the energy budget, the times of operation are limited and may be subject to some outages especially during winter.

Winter has been challenging with extended periods of outage, but service should improve with extended daylight.  The keyer now sends a code for the battery voltage.
