Since March 10, 2001 DOY=69 the IGS station NTUS is out of operation
again. We discovered after a long period of testing that the
steering feature of the internal clock of the TurboRogue receiver S/N 224 
is failing again after several repairs at Allen Osborne Associates. This
also occurred at this station with receiver S/N 229 at the time it was
installed there. This receiver has now been moved to station KOSG where it
is operating quite well connected to an external frequency standard and
the internal one disabled.
We are now seeking either for a similar solution for NTUS or replace it
temporarily by another one during its repair or replace it by a complete
different instrument. We are in discussion with AOA and await their
suggestions. We hope to bring NTUS as soon as possible into operation again.
We really appologize for this inconvenience.
