 assess  the  potential  interference  between  the  ICO  ATC  transmitters  and  MSS  systems  in  adjacent  bands  and  other  systems  in  adjacent  allocations.  For  purposes  of  the  following  analyses,  we  will 
 treat  these  limits  as  EIRP  densities. 
 19.  Table  3.2.  C  entitled  “Interference  Analysis  to  Space  Research  Earth  Stations”  in  Section  3.2  of  Appendix  C1  is  revised  to  change  the  heading  of  the  final  column  from  “ATC  AT”  to  ATC  MT”. 


 The  revised  table  reads: 
 SR/  SO  Earth  Stations  Units  ATC  BS  ATC  MT 


 Frequency  (GHz)  2.2  2.2  Range  (km)  0.82  0.09 


 ATC  Transmitter  Out-  of-  Band  Power  (dBW/  4kHz)  -100.6  -119.6  Bandwidth  Ratio  (dB)  36.0  36.0 
 ATC  Emission  (dBW/  Hz)  -136.6  -155.6  Propagation  Loss  (dB/  m  2  )  -97.5  -78.5 
 Interference  Power  (dBW/  Hz)  -234.1  -234.1  Normalized  Interference  Level  (dBW/  Hz)  -234.1  -234.1 
 Margin  (dB)  0.0  0.0 


 20.  These  errors  will  be  corrected  before  publication  in  the  Federal  Register. 
 21.  This  action  is  taken  under  delegated  authority  pursuant  to  Sections  0.51  and  0.261  of  the  Commissions  Rules,  47  C.  F.  R.  §§  0.  51,  0.261.
