From: Boudewijn Ambrosius (DUT) Subject: [IGSMAIL-1093] IRKT H-maser status and site log Date: Tue, 24 Oct 1995 10:20:10 PDT ****************************************************************************** IGS Electronic Mail Tue Oct 24 10:20:10 PDT 1995 Message Number 1093 ****************************************************************************** Author: Boudewijn Ambrosius (DUT) Subject: IRKT H-maser status and site log After the announcement of the new Irkutsk station IRKT, I received word that the H-maser connection is not operating yet. The 5 MHz line is available, but there appear to be some difficulties in configuring the TurboRogue receiver properly. We are currently trying to resolve these problems in cooperation with the people in Irkutsk. Attached to this message is the (delayed) site log, reflecting the CURRENT situation where the receiver is operating from its internal clock (with clock steering). This form has also been submitted to the IGS Central Bureau. Boudewijn Ambrosius. ********************************** SITE INFORMATION FORM ********************************** 0.
