7/31/2019 1:34:34 PM General Remotely rebooted the primary PC at ~0950 to get the M4 file creation times back to on the hour.

1/18/2019 9:11:04 AM General We were informed by YN biologist Charlie Strom the site was populated with fish on Monday and Tuesday 1/14 and 1/15/19.
5/18/2018 12:00:00 AM SiteDown ESJ down Channels were walked fish cleared.
4/11/2018 7:00:00 AM General For unknown reasons, the primary PC closed and submitted file ESJ-2018-101-P-002 after approximately one minute. Meanwhile the PC continued to interrogate to file ESJ-2018-101-P-002, then closed and submitted it at the next automated interval. The second version of the file was rejected due to identical names. File ESJ-2018-101-X-002 was created from the second file and compared to data from the secondary PC for accuracy. PTAGIS will continue to monitor, no further problems to report.
4/9/2018 3:54:39 PM General The platform was remotely rebooted for M4 file maintenance. File ESJ-2018-099-X-014 was created on the secondary PC and covers the gap in time the primary PC was down. No problems to report.
3/19/2018 7:29:00 AM General PSMFC was on site to investigate the cause for the transceivers poor efficiency. It was discovered that the transceiver had been placed into "standby" mode on Friday afternoon. There was no activity from PSMFC staff to make this occur and all indications show that the action came from the transceiver. This has never happened at any of the acclamation sites in the Past so PSMFC will be keeping a close eye on future operations to ensure that this does not occur again.
3/15/2018 12:22:00 PM General PSMFC was informed yesterday by Charlie Strom that the screens were pulled and the volitional release has begun for this season.
