Site ID:   HOLM
DOMES No:  40148M001
Location:  Holman (Victoria Island), Northwest Territories, Canada
Agency:    Natural Resources Canada (NRCan), Geodetic Survey Division

Advisory:  HOLM receiver replaced 2003-04-03 (DOY 093)

As previously noted in IGSMAIL #4316, we have replaced the Ashtech uZ 
receiver at HOLM with another using upgraded firmware. It is expected 
that the new firmware will resolve the periodic data loss experienced 
at this site. The receiver switch took place between 17:00 and 17:45 
UT on 2003-04-03 (DOY 093). A new site log has been forwarded to the 
IGS CB.

It has also been noticed by us and the AIUB Analysis Center that data 
from HOLM is of poorer quality than that from our other sites using 
the same receiver and antenna combination. We plan to investigate, 
and hopefully resolve, the problem when we visit the site this 
Summer. A faulty antenna or bad antenna cable are suspected. We 
apologize for any inconvenience this problem may cause.
