2012 October 15 -- October 17: Maintenance Visit
Menno Norden and Henri Meulman visited from ASTRON to work on the station
Updates etc. in the Container:
- RCU modem firmware upgrade to version V12. This removes the DC from the communication line when it is not used.
- Upgrade of the firmware of the TBB boot-loader. This is to improve the stability of the boards. (Less TBBs stuck in "not available" and needing a 24V reset.)
- RCU number 10 replaced, it had low gain in LBH
LBA work:
- replaced the antennas number: 4, 6, 19, 22, 27, 34, 35, 36, 37, 38, 39, 41, 43, 46, 52, 65, 69, 74, 75, 76, 82, 89, 92 (to get the RCU number multiply by two)
HBA work:
- Replaced several broken HBA frontend modules.
Tests
- Tested all antenneas and elements with a test transmitter.
