Ladies and Gentlemen

The ASHTECH Z-XII3T (ASHTECH Model Z-12
Metronome WP103) in the PTBB GPS Permanent
Tracking Station used the external frequency from
the H-Maser prior 2003-10-02.

Since 2003-10-02 the ASHTECH Z-XII3T is
connected to the external frequency from the
Cesium Frequency Standard CS2.

Yesterday I got this information. Please excuse me
for the delay of this information. 

With best regards
Rudi
