9/2/2015 2:00:00 PM General Switched MUX back over from Acument to Cellular Modem Ping
9/2/2015 1:00:00 PM SiteUp Site back up for about 5 days, troubleshooting power issues.
8/24/2015 1:19:00 PM SiteDown Site down due to power issues
8/13/2015 4:00:00 PM General Switched batter configuration from 2x2 12V in series-parallel to 4x1 6V series to troubleshoot power issues.
8/11/2015 1:00:00 PM General Switch unique mode to 300sec to address lingering residualized steelhead in field.
7/9/2015 1:00:00 PM SiteDown Operational but experiencing intermittent read success during early morning hours only from 7/9 until 7/21/2015. Site began experiencing combination of power issues and buffer overruns associated with 'camped-out' PIT-tagged residual steelhead in the antenna field. Buffer would become over-run betwen 4AM and 5AM each morning. Then site would be down from an average of 6AM through around 3AM the next morning but to both power issues and buffer issues; however unique tags were read during brief 1-3 hour periods during this time.
