RS 12/13 Preliminary Transponder Frequencies Are Provided

AMSAT-NA has learned from Ron Broadbent, G3AAJ, that the launch of RS 12/13 is
imminient.  This information was made available from reliable Russian sources
familiar with amateur satellite activities in the Soviet Union.  It is felt by
G3AAJ's colleagues in the Soviet Union that the launch of RS 12/13 will occur
sometime in June.  AMSAT-NA urges all OSCAR enthusiasts to monitor the planned
beacon frequencies for both RS 12 and RS 13.  The following table is a
"preliminary" list of frequencies for RS 12/13 as AMSAT knows them today.
