<DIV><FONT face=Arial size=2><SPAN class=665054220-21072004>The reason for the
request is that ARINC, Inc.(see <A
href="http://www.arinc.com">www.arinc.com</A>) has applied to the Federal
Communications Commission for a license to operate airborne mobile earth
stations in the Fixed Satellite Service band (14.0 - 14.5 GHz). To
properly protect NRAO sites we are entering into an agreement to cease
transmitting when approaching line-of-sight to your active observatory
sites. While we have the exact coordinates of those sites, we need to
account for their elevations in order to provide proper protection for
lower observatory look angles. </SPAN></FONT></DIV>
