1. CONCLUSIONS



An interference study considering all existing, proposed and prior coordinated microwave
facilities within the coordination contours of the proposed earth station demonstrates that
this site will operate satisfactorily with the common carrier microwave environment.
Further, there will be no restrictions of its operation due to interference considerations.

2. SUMMARY OF RESULTS


This minor coordination notice is for the addition of digital emission designators to Call
Sign E920588. The transmit power for the digital carriers will be -13.01 dBw/4KHz. This
power is 12 dB lower than the existing power for the analog carriers. The satellite arc and
frequency ranges remain unchanged. All potential interference cases will be 12 dB lower
than the cases for the existing parameter.

Due to the minor nature of the notice, this information is for your records only and no
response is required.
