Check the Status Monitor to see if the Cross-over switches and RCP IF Attenuators are at the default levels:

• At all sites, cross-over switches should be Direct
• IF Attenuator settings should be as follows
  • At Hobart:
    • S RCP : 0.0 dB
    • X RCP : 12.0 dB
  • At Katherine
    • S RCP : 15.5 dB
    • X RCP : 8.5 dB
  • At Yarragadee
    • S RCP : 3.0 dB
    • X RCP : 0.0 dB

If these values are not correct, they will need adjusting. At the moment the procedure for doing this is a bit painful. Talk to an on-call person.
