1296 MHz Beacon
Frequency: 1296.905 MHz
Heading: 45° and 135°
Location: Slieve Annora
Keeper: Gordon Curry GI6ATZ
The 1296 MHZ Beacon uses the Next Generation Beacon hardware: - http://www.rudius.net/oz2m/
The reference 10 MHz Oscillator is derived from the GPSDO already in use for the 144 MHz beacon: -
The Beacon has a final RF power level of 12 watts.
The beacon transmits JT4G on the even minutes and CW on the odd minutes in the following sequence: -
00:01 – 00:51 GB3NGI IO65VB in JT4G mode
00:52 – 01:00 GB3NGI IO65VB in CW
01:01 – 01:29 Plain Carrier
01:30 – 01:40 GB3NGI IO65VB in CW
01:41 – 02:00 Plain Carrier
The sequence then repeats
To decode the JT4G, tune the carrier to obtain a tone of 800Hz with the receiver set to USB, and the dial frequency reading 1296.9042. The JT4G will then be tuned in correctly.
The antennas used for the 1296 MHz beacon are a pair of Wimo PA23R panel antennas:-
The antennas are connected to the transmitter using Andrews LDF 6-50 cable. The antennas are 10 metres above ground level.
