Fort Hays Tune Up Trip, Nov. 2015

Following the August 2015 trip to the Fort Hays radar, it was noticed that the East radar appeared to be less sensitive than the West radar. Prior to the August trip, it was believed that this might be due to operating on fewer antennas on the East radar as compared to the West radar. However, with the major repairs done to replacing the antenna feeder cables during the August trip this reason would not apply. So a trip was made by Kevin Sterne to test other a few other theories on why the East radar was less sensitive. As well, during this trip efforts would be made in making measurements to understand the time delays through the electronics. These efforts would help the radars begin to collect sensible elevation angle data.

Kapuskasing Coaxial Upgrade - Oct. 2015

As part of an outstanding project to upgrade accessibility to the array as well as to improve the performance of the radar, the Kapuskasing radar had two major projects completed within the last couple of months. The first of these projects was improving the current road from the radar building to the main array road as well as creating a brand new road from the main array road out and along the interferometer array. The second project was replacing the aged coaxial cables that carry signals from the antennas to the radar building which was performed by Kevin Sterne and Mike Ruohoniemi in mid- to late-October 2015.

Goose Bay Riometer Installation - Oct. 2015

Over the Summer 2015 in talks between VT SuperDARN and University of Calgary groups, it was noticed that there was a gap in riometer coverage in the Labrador area. The University of Calgary group was interested in installing a riometer at the Goose Bay SuperDARN site in order to fill in this gap. After a few months of planning and coordination, a trip was made by Kevin Sterne (from VT) and Craig Unick (University of Calgary) to the Goose Bay site to install the riometer.

Fort Hays Antenna Array Trip - August 2015

After a decrease in sensitivity on the Fort Hays radars, Kevin Sterne and Mike Ruohoniemi made a trip the week of August 16th to the 22nd 2015 to Hays, KS in order to assess parts needing repairs and perform what repairs could be completed. In the weeks prior to this trip, FHSU student intern Ryan White reported a few wires hanging down along the antenna arrays as well as problems with the antennas. Also, in the weeks or up to a month before the trip, one of the computers at the site began locking up.

Quick trip to Blackstone to install transmitters

A quick day trip was made by Kevin Sterne and Deven Chheda on March 27th, 2015 in order to install some repaired transmitters and give a look at the site to see how things were going. This trip was originally planned after an extended network outage as well as a fear that one of the computers at the site had gone bad. However, in the days leading up to the trip the network connection as well as the issue with the computer were corrected. This left us with smaller but also important issues to complete during this trip. One of these was to install two of the four transmitters that were being worked on in the Blacksburg lab. These two had been repaired and were ready to be installed back at the site. As well, a range calibration was performed during this trip as it was noticed that sometime in mid-September, the radar's range appeared to be off. As well, this would be Deven's first trip to a SuperDARN site, so the operations and systems were explained to Deven.

Wallops Island Transmitter Overhaul - March 2015

Early in March 2015, Kevin Sterne and Mike Ruohoniemi of Virginia Tech and Drew Knuth and Ethan Miller of John Hopkins University's Applied Physics Lab met at the Wallops Island SuperDARN site to assess the electronics and the condition of the site. This trip would serve to prepare for a larger trip during the summer where more effort will be put into enabling elevation angle data to be collected by the radar. As well, this trip would take care of a few outstanding issues including a check of the transmitters and radar control electronics.
