Following the March 2018 day trip to Blackstone, it was noticed that about 5 to 6 transmitters were not on or running for various reasons. As time did not allow of any kind of electronics checks during the previous trip, this trip was made by Kevin Sterne and Dr. Mike Ruohoniemi to review and make repairs on the electronics inside of the building. It was hoped that any outdoor work on the antennas could be performed during this trip, but logistics did not allow for making it worth renting a high-lift. In addition, the newly installed wireless hop system would be re-checked to see about improving the connection as it was still experiencing some minor problems despite staying up for the majority of the time.

Following an extended period of problems with the network connection to the site, a trip was planned after some new equipment was purchased to replace the aging wireless bridge system. The network connection has been a problem since the site was constructed, and in particular since the installation of new radios in 2011. However, through late 2017 and early 2018, the network connection was mostly down leading to long backlogs of data. To resolve this problem, new antennas, mounting hardware, and Ethernet cable were taken out to the site along with replacement radios that were in the lab. This trip was made while Mike and Kevin were coming back from Wallops Island in the two days prior. Of course, upon arriving to the site, the network connection was working.

After examining the condition of many of the radars, it was determined that a major effort should be put into repairing the antenna array at Wallops Island. This effort also follows work done by Mike and Ethan along with Rob Pfaff to get the grounds around the antenna arrays cleared out and maintained in late 2016 and 2017. During this trip, Mike and Kevin took stock of what exactly needed to be repaired on the antenna arrays and get some order sheets going. With additional time, the RF performance of the transmitters and antennas would be measured to quantify the amount of repairs needed. Dr. Ethan Miller and Dr. Patrick Dandenault from APL joined us for a day to review the antenna array repair project.

Following the May 2017 trip, the west main reflector array still needed to be rebuilt with a little over half of the wires still needing to be strung up. This trip would also serve as the last tune up of the radar prior to the Great American Solar Eclipse of 2017.

Following an ice storm in January 2017 and an assessment trip in Feb. 2017 a major trip was made to make repairs to the West main antenna array reflector so that the west radar was fully functional well prior to the August 2017 solar eclipse.

Following the November 2016 trip, the correct size (5/8” rod) of CADweld mold was ordered in order to complete the grounding work that had been long overdue. However, winter cold and wet set in and so the work could not be completed until better temperatures arrived. In the month prior to this trip the internet connection to the site had been out for several days if not weeks at a time going on 3 to 4 weeks. So with these issues, a trip was planned to take care of these issues and make sure the radar was running fairly well (with known issues on the antennas).
