Hardware Status as of 1. July 2011
Electronics:
Nearly everything working.
All RCU modules plugged in.
High Band Antennas:
All tiles are working
Low Band Antennas:
No oscillating dipoles.
Some (even-numbered) dipoles show little to no power in the spectrum (like as if the LNA is not working). The problem is not always consistent: some seem to recover without active intervention, some seem to recover after pulling and re-connecting the RCU.
