As during this trip, the antenna arrays were checked out for any damages or possible places where attention made needed in the future. In addition, 3 phasing cards were installed for the interferometer array but the interferometer antennas were not connected to the phasing cards as no limiters were on hand. Limiters on these RF paths will help protect the sensitive phasing cards from being damaged by induced signals from the main arrays as well as electrical storms. However, SWR readings were taken on the interferometer antennas and all of the antennas are properly tuned up and working.

Following the trip from April/May 2013, a persistent problem developed with the QNX computers network interface cards. The cards would randomly lock up and not accept any new connections on a time scale of 12 hours to a couple of days. To bring the Fort Hays radars back online, a hard reboot was performed. However, after several months of this type of treatment, the linux computer failed.
During this trip, a new linux computer was taken out to the site and successfully installed. This computer is using radar operating software provided by Jef Spaleta's (University of Alaska Fairbanks) github repository. Using the github software development, future changes to the code will be tracked and implemented at the radar site. |
