2002 4/9/2002 12:00 PM 1/1/2003 12:00 AM This was the first year of operation. The Oregon Shore ladder at MCN watered up on 3/8/02. The production PIT tag interrogation platform began operation at the McNary Oregon Shore adult ladder (and counting window) on 04/09/2002 around 14:00 PDT. Data from coils 03 through 12 was collected between 4/3/02 16:00 and 4/9/02 14:00 and submitted in interrogation file MC102099.S. Data from the counting window, coils 01 and 02 may precede this. NOTE: date/time stamps associated with fish records collected prior to 14:00 on 4/9/2002 relate to the time that data was retrieved from the transceivers and NOT the time that the fish transited the ladder.


Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active.

6/4/2022 8:25:28 AM ErrorsCleared There was a short period of noise on 02. PSMFC went to the site to investigate the cause but unfortunately when we arrived the noise had subsided. The counting window and the area around the antenna were inspected for possible sources but none were found.
6/3/2022 7:31:09 AM ErrorsCleared It appears that there is noise on the system at this time. We have been investigating this occurrence but have not located the source. The system is detecting at 100% efficiency at this time.

Checked and tuned transceivers.

CW 02 had slightly elevated noise on arrival. Unplugged LED lighting and noise was gone. Plugged it back in and it was still gone. Move LED lighting P/S further away from antenna. Air conditioners in PIT tag room weren't working. Bottom AC is on and not running. Top AC had GFCI tripped. Reset and AC is running but sounds like it's about to fail. Rattling and groaning. I'll let Bobby know.

5/30/2022 9:55:38 AM ErrorsCleared The system had 3 noise events where noise was present for 6-7 hours. The noise levels reach as high as 50% during these events. We'll monitor to see if the noise continues and investigate the site if it does.
