Hi Luc VE2DWE,

The SPACE CONFERENCE WARC for Space Telecommunicatiom Geneva, 1971
predates the use of  432.15 MHz for amateur satellite service (ASS)

In that Conference the decision to adopt the 435-438 MHz band  for the
amateur satellite service ( ASS ) was ratified during plenary meeting .

Is in that Conference 1971 that ASS was ,decided,accepted and added
to the ITU regulation  on  definition  84 ATA

" This is Amateur-satellite service: a radiocommunication service using
space stations on earth satellites for the same purpose as those of the
amateur service."

Is in that Geneva 1971 Space Conference that the amateur satellite service
previously confined in 144-146 MHz was allocated to the following bands:

       7000   to   7100  KHz
     14000  to  14250  KHz
     21000  to  21450  KHz
     28000  to  29700  KHz
         144  to  146      MHz
         435  to  438      MHz
        24,0  to  24,05   GHz

This constitutes a factual record of the events affecting the amateur
service during the WARC-79

OSCAR-7 was launched nov 15,  1974  and as a PARADOX  it is tree years
after the above 1971 ITU Geneva Space Conference when already the ASS
was defined and  the 435-438 MHz was allocated to it.

For more detailed informations on this matter read please the
IARU Region 1-2-3 document published August 1971
