The switch was prompted by the faltering Trimble 4000 SSE receiver original to the site. The retrofit was accompanied by a site tie to PVE2 (~10m away) two days prior to and after the hardware change. Another marked change is the extraction of the fiberglass antenna enclosure; the antenna is currently "naked", but will be installed with a new SCIGN antenna dome when they become available. The sitelog will reflect the recent changes at the station. Images of the station are available at: http://www-socal.wr.usgs.gov/galetzka/images/PVEP/ Thanks for your attention, John Galetzka Network Coordinator Southern California Integrated GPS Network (SCIGN) USGS-Pasadena galetzka@gps.caltech.edu 626-583-7230 [Mailed From: John Galetzka ]
