RWP, C1 Operational

NSA
KAZR, C1 Operational
  1. RDS1 power supply was replaced and the signal processor is operational.
  2. The system will be taken out for maintenance for a short time to replace a fan.
KASACR, C1 Not Operational
  1. Refurbished DSAs installed
  2. Azimuth axis is still not functional.
  3. Not operational, but undergoing tests.
  4. Chiller is not functional.
  5. Refurbished servo amplifier will be shipped to the site in the second week of October.
WSACR, C1 Not Operational
  1. Refurbished DSAs installed
  2. Azimuth axis is still not functional.
  3. Not operational, but undergoing tests.
  4. Chiller is not functional.
  5. Refurbished servo amplifier will be shipped to the site in the second week of October.
XSAPR, C1 Not Operational
  1. Spare motors shipped back to Parker for refurbishment.
  2. Elevation servo amplifier not functioning.
  3. New servo amplifier (different model) under testing for RCP8 upgrade being done.
RWP, C1 Operational

ENA
KAZR, C1 Operational
KASACR, C1 Operational
  1. Mentor will visit site to perform calibrations.
  2. Pedestal is operating with the refurbished servo amp.
  3. We will continue to monitor its performance for any software bugs.
WSACR, C1 Not Operational
  1. Radar is down because replacement chiller has been in customs since December 15, 2016.
  2. Repaired parts for the chiller have been shipped.
XSAPR, C1 Testing
  1. Vendor is working with site operations to debug and repair the radar.
  2. Currently operating. There are still a few issues to resolve before we start the 24x7 test:
    • Potential leak in the waveguide that makes the dehydrator run a lot.
    • Phase lock alarms on stable local oscillator (STALO).
    • Temperature alerts in the antenna mounted electronics (AME) enclosure.
RWP, C1 Operational

AMF1
KASACR Operational
  1. UPS has been installed, but we are seeing error reports on the UPS.
  2. Pedestal servo amplifier went through extensive failure analysis and the vendor is going to ship the repaired servo amplifiers. Based on the analysis, it appears that faulty capacitors were used in production. Servo amps will be replaced in all pedestals with the repair performed as we get the repaired ones back from the vendor.
WSACR Not Operational
  1. Transmitter is faulting.
  2. There is no signal in the receiver.
  3. Pedestal servo amplifier went through extensive failure analysis and the vendor is going to ship the repaired servo amplifiers. Based on the analysis, it appears that faulty capacitors were used in production. Servo amps will be replaced in all pedestals with the repair performed as we get the repaired ones back from the vendor.
WACR Operational
  1. Transmitter faults occasionally.
KAZR Operational
RWP Operational

AMF2
KAZR In Transit
XSACR In Transit
  1. Radar is being packed for transit.
  2. Pedestal servo amplifier went through extensive failure analysis and the vendor is going to ship the repaired servo amplifiers. Based on the analysis, it appears that faulty capacitors were used in production. Servo amps will be replaced in all pedestals with the repair performed as we get the repaired ones back from the vendor.
KASACR In Transit
  1. Radar is being packed for transit.
  2. Pedestal servo amplifier went through extensive failure analysis and the vendor is going to ship the repaired servo amplifiers. Based on the analysis, it appears that faulty capacitors were used in production. Servo amps will be replaced in all pedestals with the repair performed as we get the repaired ones back from the vendor.
MWACR In Storage
  1. Work on the transceiver has begun at PNNL.
  2. Transmitter tube (EIK) needs to be repaired and refurbished.
RWP Operational

AMF3
KAZR Operational
  1. Analysis on-going.
  2. We are experimenting with a clutter fence. A temporary fence is added to see the affect on clutter.
KASACR Operational
  1. Calibrated noise sources were installed.
  2. Refurbished DSA (digital servo amplifier) were installed.
WSACR Operational
  1. Refurbished DSA (digital servo amplifier) were installed.
RWP Operational

Other
CSAPR2 Functioning
  1. To minimize pedestal damage due to high winds we will follow the following procedure:
    • Weekdays (except when site is closed for holidays): The pedestal shall be put in stow position no sooner than 4:00 PM with exception when there is inclement weather. Site operations perform a daily round (just visual inspection till we have a detailed daily round like CSAPR)
    • Weekends and holidays: The pedestal shall be stow position. The on-site operator perform a quick visual inspection of the CSAPR pedestal, trailer, and antenna.
CSAPR Unavailable
  1. System disassembled and not in functional state.
KASACR Unavailable
  1. System at PNNL for complete characterization.
  2. Pedestal servo amplifier went through extensive failure analysis and the vendor is going to ship the repaired servo amplifiers. Based on the analysis, it appears that faulty capacitors were used in production. Servo amps will be replaced in all pedestals with the repair performed as we get the repaired ones back from the vendor.
XSACR Unavailable
  1. System at PNNL for complete characterization.
  2. Pedestal servo amplifier went through extensive failure analysis and the vendor is going to ship the repaired servo amplifiers.
