Administrative Circular CA/3				18 January 1994


TO ADMINISTRATIONS OF MEMBERS OF THE ITU AND 
OTHER MEMBERS OF THE RADIOCOMMUNICATION SECTOR


Subject:	Invitation to participate in the work of
		the Radiocommunication Study Groups in
		the study period 1994-1995

	The Radiocommunication Assembly, in November, 1993, approved 
revised work programme, structure and working methods for Radiocommunication
(ITU-R) Study Groups for the 1994-1995 Study Period (See Annexes 1, 2 and 3).
This Circular invites participation of Administrations and other members of
the Radiocommunication Sector in the work of the Study Groups and their
component Working Parties and Task Groups.  From 31 March 1994, the list of
participants and document requirements will be newly established on the basis
of replies to this Circular.  

	The Chairmen and Vice-Chairmen of former and new Study Groups, in
a meeting from 22 to 23 November 1993, in consultation with the Director,
established the calendar of meetings for 1994 and provisionally for 1995
(see Annex 4).  It should be noted that former Study Group 12 has been
renumbered Study Group 2 as of 16 November 1993  (see Annex 3).  Other
changes in the Study Group structure and chairmanships are effective at
the close of  Study Group meetings to be held in March 1994.  The meetings
calendar is fixed for all activities, except Working Parties of the new
Study Group 3, which are shown in block.  During the March meetings of
Study Groups, specific dates will be assigned in the block.   

	Names and addresses of Study Group Chairmen and Vice Chairmen are 
given in Annex 5. 

	Attention is particularly invited to the Working Methods (Resolution
ITU-R 1) given in Annex 1. These establish procedures and deadlines for
contributions to Radiocommunication Study Group work.  Documents for
consideration in meetings held after March 1994 will be numbered in the
new 1994-1995 series.  In accordance with Resolution 59 of the Plenipotentiary
Conference, Nice 1989, relating to the use of working languages of the Union,
reciprocal interpretation among the working languages of the Union may be
provided at Study Group meetings, within the resources available.  Ninety
(90) days advance notice is requested from the Member requiring interpretation.
Due to limited resources, Working Parties and Task Groups are encouraged to
use only one of the ITU working languages. 

	Annex 6 gives a list of ITU-R Resolutions in force from 16 November
1993. Texts approved by the Assembly are in preparation for publication
according to the contents shown in Annex 7.   A separate Circular invites
subscriptions to purchase these volumes.

	Annex 8 provides a form  for announcement of intention of Adminis-
trations or other members to participate in specific Study Groups, Task
Groups or Working parties and to receive documents. If you wish to modify
your existing request of documents  presently on file, please return this
form as soon as possible, preferably not later than 28 February taking into
account that your new request will erase and replace all orders currently on
file for your Administration/Organization.
