| Date | Time | General Notes | |||||||
| 28/09/14 | NOV received. | ||||||||
| 04/10/14 | System firmware rewrite. | ||||||||
| 08/10/14 | 20:00 | System on test into dummy load. | |||||||
| 10/10/14 | System on test into dummy load. Several internet connectivity outages due to router configuration issues. | ||||||||
| 13/10/14 | 12:00 | System running on temporary low level antenna (¼ wave @ 2 MAGL within building). | |||||||
| 17/10/14 | 18:00 | System running on temporary external antenna @ 6 MAGL. TXCVR O/P power reduced to -6 dBW by the inclusion of a 6dB attenuator in the antenna feed line. Secondary client bridge router 5v power supply now taken from systems internal 5v regulator. An approximate 2 hour outage was experienced during the alterations detailed above. | |||||||
| 18/10/14 | 14:00 |
Several short outages whilst 1) the TXCVR
Configuration was amended, & 2) the SVXlink firmware configuration
was amended. Changes made were to improve system behaviour in terms of both CTCSS encode and decode – CTCSS encode is now disabled in SVXlink and enabled on the TXCVR, whilst CTCSS decode is enabled in SVXlink and disabled on the TXCVR. |
|||||||
| 30/10/14 | 13:00 | Short outage whilst replacing the controller enclosure. | |||||||
| 26/11/14 | 21:00 | USB port on system controller forced to 12Mbps data rate (USB1.1) - trial to reduce slight noise on tx audio. Although this seems to have had little or no effect on tx audio, the USB port has been left at the lower rate to keep system overheads to a minimum. | |||||||
| 27/11/14 | 20:30 | Change default UID 1000 username & password, disable remote access to username ROOT, finally restart system and start fetchmail daemon. | |||||||
| 23/12/14 | 12:30 | Secondary router placed into DMZ off primary router - secondary router now run outside of the primary routers firewall, leaving security to the secondary router. | |||||||
| 31/12/14 | 11:30 | Short outage (~3 hrs) due to loss of internet connectivity. | |||||||
| 05/03/15 | 16:30 | Temporary loss of Echolink access, Meteorological reporting, and VHF lift condition reporting - due to internet outage. | |||||||
| 16/05/15 | 19:45 | Temporary loss of Echolink access, Meteorological reporting, and VHF lift condition reporting - due to internet outage. | |||||||
| 28/07/15 | 12:00 | Temporary loss of Echolink access, Meteorological reporting, and VHF lift condition reporting - due to internet outage. | |||||||
| 07/09/15 | NOV renewal application submitted. | ||||||||
| 10/09/15 | NOV renewal received. | ||||||||
| 01/11/15 | 11:00 |
Logic system restart - after primary router restart
and change of public IP address. Implement internet timekeeping synchronization. |
