Automatic Outage: Radials older than 12 hours. Operator should investigate.
Outage cleared automatically. Radial files have caught up since initial reporting.
(TGU) GPS monitor reported antenna shorted, plugged in new Garmin antenna, same warning, replaced the GPS board in the receiver (#2005127) with the board from receiver #2004111 and this fixed the problem. Checked loop resistances at back of rx: loop 1 3055 ohms, loop 2 2979 ohms.
2026-04-17 14:39:54 GMT rwsadmin (TGU) checked site, drone APM at 400 meters, swapped out backup data disk
2026-04-21 14:16:13 GMT rwsadmin (TGU) GPS monitor reported antenna shorted, plugged in new Garmin antenna, same warning, replaced GPS board B11859-46006 0422 in the receiver (#2005127) with GPS board 12118-27023 0645 taken from receiver #2004111 and this fixed the problem. Checked loop resistances at back of rx: loop 1 3055 ohms, loop 2 2979 ohms.
2026-04-21 15:45:02 GMT rwsadmin (TGU) opened base of rx antenna, checked the loop 2 cable with 50 ohm resistor, looks good, all cable connections are correct at base, cleaned out spider webs, attempted walking APM, but could not see the transponder signal
2026-04-23 20:01:08 GMT rwsadmin (TGU) Today the GPS monitor is reporting some intermittent problems with satellite tracking. I turned off the transmit drive control for GPS not ready, the PLL unlocked and GPS Unsynced are still turned on. Will check for any problems with interference.
2026-04-24 14:55:18 GMT rwsadmin (TGU) major interference in spectra first appears at 9:30 UTC and very strong by 11:00 UTC, changed max speed in FOL from 280 cm/s to 50 cm/s temporarily to reduce impact on radials
2026-04-27 15:29:27 GMT rwsadmin (TGU) set the max current in FOL settings to 250 cm/s
2026-04-27 15:33:25 GMT rwsadmin (TGU) did not see any other interference of same type and intensity as the interference on Apr 24, which appeared around 9:30 and was gone by 16:30 UTC, did not see any interference from other CODAR systems, check range display in SS Acq to confirm peaks in same locations as before
