Interrogation Site Metadata

Site operations for 2023 came to an end on 6/2/2023 after the TEG had run out of fuel and batteries powering the MUX were completely discharged.  The site was visited on 6/9/2023 to uninstall and remove all components.

Site visited to assess operations, replace TEG fuel tanks and to download MUX buffer.  Site operating normally upon arrival.  Both antennas tuned and tested prior to leaving the site.  

Site visited to assess operations, replace TEG fuel tanks and to download MUX buffer.  Site operating normally upon arrival.  Both antennas tuned and tested prior to leaving the site.

Site visited to assess operations, replace TEG fuel tanks and to download MUX buffer.  Site operating normally upon arrival.  Both antennas tuned and tested prior to leaving the site.

Site visited to check operations replace TEG propane tanks.  Upon last visit (4/19/2023) TEG had run out of fuel and batteries completely discharged.  The site was down temporarily from 4/18/2023 through late 4/19/2023 due to the fuel outage.  Site operating normally upon arrival during this visit.  Fuel tanks replaced, data collected from MUX buffer, antennas tested and tuned prior to leaving site.

Site visited to exchange propane tanks for the TEG, download MUX buffer and to assess site operations.  Fuel tanks empty and TEG not operating upon arrival at the site.  Batteries completely discharged and MUX not operating.  Propane tanks were exchanged and TEG was restarted.  Site will be revisited asap to check on operations.

Site visited to exchange propane tanks for the TEG, download MUX buffer and to assess site operations.  Site operating normally, both antennas tuned and tested prior to leaving site.

Site visited to exchange propane tanks for the TEG, download MUX buffer and to assess site operations.  Site operating normally, both antennas tuned and tested prior to leaving site.

Site visited to exchange propane tanks for TEG, download MUX buffer and to assess site operations.  Site operating normally, both antennas tuned and tested prior to leaving site.

Site visited to check operational status and confirm that the TEG was still operating normally.  Antenna 02 (downstream) had a low exciter voltage alarm and very low read range so it was replaced with another 10' antenna with better read range.  Both antennas tuned and tested prior to leaving site, operations normal.

Site visited to check on site operations.  TEG was not running upon arrival at the site.  TEG was restarted and operating normally upon leaving the site.

Site infrastructure installed on 2/27/2023 and spring operations initiated.  Both antennas tuned and tested prior to leaving site, operations normal.

Returned to site to remove the TEG, TEG enclosure and job box from the site.  All components now removed from the site and will be reinstalled in early 2023 to resume array operations.

Site visited to terminate operations for the year and to uninstall components from the site.  The MUX was powered on and had operated until 6/4/2022 at 11am PST before voltage fell below the threshold and it shut down, effectively ending the operational period for PWA during 2022.  Both antennas were uninstalled, removed from the stream channel and brought back to Clarkston.  Will return as time allows to remove the TEG, TEG enclosure and job box/electronics box from the site.

Site visited to change out propane tanks and check on operations.  TEG not operating (out of fuel) upon arrival at the site.  The battery bank voltage had fallen below 24v and MUX was also powered off upon arrival at site.  Propane tanks were replaced and the TEG restarted without issue.  Once the TEG was outputting enough power to turn the MUX back on, it was determined that MUX had operated until approximately 8am that morning of 5/18 and had only been down for two hours.  Both antennas tested and operating normally prior to leaving the site.

Site visited to replace TEG propane tanks, download MUX buffer memory and to assess site operations.  Site operating normally upon arrival.  Both antennas tuned and tested prior to leaving site. 

Site visited to replace propane tanks for TEG.  TEG was not operating (out of fuel) upon arrival at the site, however the batteries were still outputting 24.7v and the MUX was powered on with both antennas operating normally.  The propane tanks were replaced and the TEG restarted without issue.  Both antennas tested and operating normally prior to leaving the site.

Site visited to replace propane tanks for TEG and to check on operations.  TEG was not operating (out of fuel) upon arrival at the site, however the batteries were still outputting 24.6v and the MUX was still powered on and operating both antennas normally.  Fuel tanks replaced and TEG restarted without issue.  Both antennas tested and operating normally prior to leaving the site.

Site visited to replace propane tanks for TEG and to check on operations.  TEG outputting 28.5v and operating normally.  Both antennas tested and operating normally.

Site visited to replace propane tanks for TEG and to check on operations.  TEG outputting 28.5v and operating normally.  Both antennas tested and operating normally.

Site visited to replace propane tanks for TEG and to check on operations.  TEG outputting 28.5v and operating normally.  Both antennas tested and operating normally.

Site visited to replace propane tanks for TEG and to check on operations.  TEG outputting 28.5v and operating normally.  Both antennas tested and operating normally.

Returned to site after 24 hours of operation to check status.  TEG still ouputting 28.5v and operating normally.  Exciter 2 alarm present (low current on antenna 02), antenna 02 tested and still reading tags within an acceptable range (approximately 18").

All site components installed and operations initiated for PWA.  TEG started without issue and outputting 28.5v once up to temperature.  Both antennas max tuned and tested prior to leaving site.
