Site visited to replace the Can BUS cable that serves the node for antenna 04.  Once installed, the node was reconnected to the MTS and antenna 04 was tuned, tested and now operating normally.  The site is now 100% operational with all 6 antennas operating normally.

The source of the short circuit has been found in the CAN Bus line from the downstream junction box that serves the ACN for antenna 04.  The damaged CAN Bus line has been disconnected from the junction box and the CAN Bus lines that serve antennas 03, 05 and 06 have all been reconnected.  A replacement CAN Bus line for antenna 04 will be built and installed asap.  All antennas with exception of 04 are now operating normally at the site.  All five working antennas were tested and tuned prior to leaving the site.

A new CAN Bus cable has been installed that runs from the Master Controller to the downstream junction box that serves antennas 03-06.  Once the new CAN Bus cable was installed and connected to the Master Controller the same short circuit issue that was present with the previous cable returned.  More trouble shooting is required to determine the source of the short and until that time antennas 03-06 will be down as they have been since July.  Antennas 01 and 02 (North Fork and South Fork) continue to operate normally at the site.

Antennas 05 and 06 have been anchored back into their former positions after being unburied and removed from the stream channel in July 2023.  Both antennas have been connected to their nodes and should operate properly once the downstream CAN Bus cable running from the Master Controller to the downstream junction box (antennas 03-06) has been replaced.

Antennas 03 and 04 as well as their ACN/nodes have been reinstalled in their former positions after being buried by flow events last winter and spring and subsequently unburied and removed from the stream channel in July.  Antennas 05 and 06 have not yet been reinstalled but will be in the coming weeks.  Antennas 01 and 02 (NF/SF) continue to be the only antennas operating at AFC as the CAN Bus cable that runs from the Master Controller to the junction box that serves antennas 03-06 has a short and a replacement is being procured.  

Site visited 8/21/2023 to download master controller buffer and to secure antennas 03-06 as a potential flood event may occur in the Asotin basin.  Upon arrival at the site the MC was powered off but the battery charger and switcher still had power, indicating there was likely a short in one of the CAN Bus lines running either up or downstream of the MC.  After further investigation it was determined that the short was in the downstream CAN Bus line that supplies antennas 03-06.  This damaged CAN Bus line will be replaced as soon as possible.  Fortunately antennas 03-06 are currently out of the stream waiting to be reinstalled.  Antennas 01 and 02 (NF and SF) continue to operate normally at the site.

Site visited 8/7 and 8/8/2023 to remove antennas 03, 04, 05 and 06 from their buried positions.  All four antennas were buried under inches to feet of substrate after the flow event that occurred in late December of 2022.  Each antenna was dug up and removed from the stream channel, including each node and the cabling running to them.  All four antennas will be reanchored into new positions (roughly the same) later this month.  Only antennas 01 and 02 currently operating at the site.

A replacement antenna 01 (NF) has been installed in the location of the previous antenna that was dislodged and damaged during a flood/debris event that occured on 12/30/2022.  The new antenna 01 was reconnected to its node and tuned once installed, resuming normal operations.  Currently antennas 01, 02, 03 and 05 are operating normally at AFC.  Antennas 04 and 06 are present at the site but disconnected from their nodes and buried under 1-2 feet of cobble.  The work to repair/reconnect antennas 04 and 06 will occur in Auguest 2023.

Site visited 12/30/2022 to download buffer and assess damage from an ongoing flood event that began on 12/26/2022.  Asotin creek remains too high to fully assess damage to the array, but it appears antenna 01 (NF) has been disconnected from its node and partially broken loose from it's anchored position.  Antennas 04 and 06 (mainstem, river right) have been disconnected from their nodes but appear to still be in their anchored positions and buried under several inches of rock.  Antenna 02 (SF) remains connected and operating normally.  Antennas 03 and 05 (mainstem, river left) remain connected and operating normally, however both antennas appear to be buried under several inches of river rock.  Another site visit will occur the week of 1/1/2023 to further assess damage to the array once stream flows have subsided further.

Site visited 7/26/2022 to reinstall antenna 01 (NF antenna).  Antenna 01 had been disconnected from its node and broken free of all but one anchor at approximately 11 pm on May 7, 2022 and was then removed completely from the stream channel on May 14, 2022.  Antenna 01 was reinstalled in the same location it previously resided and reconnected to its node without issue.  All six antennas now operating normally at the site once again, all antennas tuned and tested prior to leaving the site.

Site visited for general maintenance and operations check after recent and ongoing high water event in the Asotin basin.  Upon arrival at the site antenna 01 (NF Asotin) was disconnected from its node and broken free of all but one of its anchors.  Antenna 01 was removed from the stream channel, does not appear to be damaged and will be reinstalled this summer once stream flows recede.  Antennas 04 and 06 were disconnected from their nodes upon arrival at the site and appear to have been disconnected by flows/debris around 11pm on May 7, 2022.  Both antennas 04 and 06 were reconnected to their nodes and tuned.  Antennas 02-06 all operating normally upon departure from the site on May 14, 2022.

Site back up after replacing all components damaged during the Dry Gulch fire in July of 2021.  Components replaced include:  all CAN Bus cabling at the site, antennas 5 and 6, as well as the node/ACN for antenna 5.  All nodes were fully tuned and site has resumed normal operations.

The powerline supplying the site has now been replaced and power has been restored.  The previous powerline was knocked down by a falling tree during the Dry Gulch fire back in early July.  The site will remain down until the CAN Bus cabling damaged by the fire can be replaced.

Site down due to damage sustained from the Dry Gulch fire.  Based on data retrieved from the Master Controllers external USB drive, the MC powered off at 00:03 hrs PST on July 10.  Site components damaged by the fire include: antenna 05 and its node/ACN, both CAN bus cables and all other cabling at the site, the downstream junction box that serves antennas 03-06, and the power line that supplies the site was damaged by a falling tree.  Fortuitously, all other site components sustained no damage and should be completely operational once the damaged components are replaced.  Until those damaged site components can be replaced, AFC will remain down.
