Phone Conference Summary  July 13, 1998
       ===========================================

Attending: Scott, Shepherd, Mundy (Mark Hodges sitting-in)

  There was a very short discussion of the A-array 
and Wildcard memos. Since Mel, Ed, and Nick were not
present, we will seek their feedback next time. In
response to Mel's email questions, Steve said that
only one of the remote pads is visible from Highway 395
and they propose to move that one so that is is not
visible. Steve and Mark will measure the z-height of
the proposed pads; Lee will see about including that in
the modeling (Debra said that her programs did not allow
for z).

   Steve reported on the progress of the site survey. They
have done a first pass marking the pads at the end
of the star and all remote pads except for the two to the north.
Their measurements involve an iterative procedure since the realtime
readout must be corrected after-the-fact to yield absolute
positions. They plan to have a second iteration and perhaps a
third. The hope is to complete the measurements by the end of
this week (July 17), or first of next week. 

   Steve said that there were some difficulties fitting the star 
in with the detailed geography (trees, hills, etc). They may need 
to shorten certain arms by 50 meters or bend the ends of the arms a 
little. Steve and Mark will chose alternative positions where 
necessary; Lee and Debra will evaluate the alternative pad positions 
and select the best options.

   The possibility of a more compact array than the D-array was discussed.
Leo requested that we look into the details of such a configuration
and it was generally agreed that we will. Debra suggested that we call 
it the S-array, rather than the E-array, so that it wouldn't be 
confused with an Equatorial array -- thus was born the Short-spacing 
array, S-array. The details of roads and the movement of antennas
need to be considered at some level in the S-array. Lee will have
a first look at possible configurations and pass along suggested
configurations to Debra. 

   We all thought that we would try to keep the Wildcard proposal in 
the plan even if the S-array is explicitly included in the EIS. If 
the S-array is spelled-out, the proposed number of wildcard pads can 
be reduced -- perhaps to 3 to 5.  Steve agreed that the exact pad 
locations for the S-array are NOT on the critical path for on-going 
site work since they will be contained within the proposed 
Wildcard area.

Action Items:
=============

1. Steve and Mark complete the site survey and produce a list of
   pad locations, and alternative locations as necessary. Target
   date for list of pad locations: July 17 to 20.

2. Lee and Debra will evaluate the measured pad locations and suggest
   the best configuration. Target date for completion: July 27.

3. Lee and Debra will make a cut at the S-array. They will produce a
   memo in time for the August 3 call.


!! Next Proposed time: August 3, 11 PST !!
