This shortcut overloaded the UPS and the entire equipment (ROGUE SNR-8, Rb frequency standard and others) was switched off and some of them damaged, mostly fuses. We are now in the process of installing the new TurboRogue SNR-12 GPS receiver and trying to get the RB frequency standard under control. In the meantime the GPS-receiver is installed and is connected to an own built crystal oscillator with a rather stable frequency. We are collecting the data and checking it on the reliability. As soon as we think that the data can be released we will do it immediately. A new stationlogsheet will be submitted to the IGSCB consequently. We really regret that this happened and were never aware of the weakness that a UPS could be overloaded and could damaging other equipment. If there is similar experience at other stations pse let me know and inform me about precautions. [Mailed From: vanloon/geo@geo.tudelft.nl] [Mailed From: Robert Liu ]
