10/19/03 13:35-14:55 Station was 'down' per GOES data. Visited site: still running but old SE110 transmitter at 2W output. Swapped in repaired SE120 and station back on air. SDR/Metppf retrieved and merged in later in day. Kh2oV at ~0v however we had lots of rain overnight and drizzle while there so we didn't consider it a problem. DCOM332 - EVE problem? after 'starting' when replacing goesid (ie from s05_0110.xmt to s05_0120.xmt) the bootup failed claiming: 'unable to open krypton.dat' even though it was there. Played around a bit and had to perform a 'reboot' using the hard-pulled reset line low. That worked. ie teardown note: this cpu may have some intermittent on the ramdisk. I'll slap in a note on the notes.
An analysis of the noise inducing effect of the GOES transmissions, as is apparent from examination of high-rate data. The location of the antenna were changed for some stations, generally from the South leg to either the West leg or to a Post, located west of the west leg. The date of the change is noted. The intensity of the GOES spikes are indicated: S strong M medium Weak Station Antenna Location Changedate Signal PP O3 T Tsfc Comment Stn 1 Yagi S leg (Needs moving) - Stn 2 Yagi S leg 10/14 S W leg w Sucessful Stn 3 Yagi S leg - Stn 4 uStrip W leg - Stn 5 uStrip S leg - Stn 6 uStrip S leg - Stn 7 uStrip S leg - Stn 8 uStrip S leg 10/15 Post Sucessful Stn 9 uStrip S leg -
Site visit to station 7, Sept 18; Kurt Arrived at site 1440 GMT R&R transmitter, still no transmission. R&R cables & antenna, still no good. Tried multiple combinations of transmitters, cables and antenna and finally got station to transmit. Suspect intermittent cable from SE 110 transmitter to EVE front panel, but have no replacement at this time. Need to watch station for possible transmit failure. Will test suspected bad SE 120 transmitter at base. Kurt tested SE 120 transmitter at base, 9/20/03. Transmitter is toast. KH2O output = 452 mV at 1641 GMT Lowered mast 1642; cleaned KH2O, output = 718 mV @ 1650 Raised mast 1648 Cleaned radiometer Dowloaded fastout and local data storage Qsoil = 29.75 % @ 1708 Took soil sample @ 1710 Trime readings @ 1715: 17.8 % @ 45 deg angle (no pilot tool needed) 28.2 % @ 60 deg angle 24.0 % @ 30 deg angle (this looked like 3 cm depth)
