For Field Day this year AO-51 will be in a dual repeater mode, with the 
following frequencies:

L/U repeater
Uplink 1268.700 FM, no PL tone
Downlink 435.150 FM

V/U repeater
Uplink 145.920 FM, no PL tone
Downlink 435.300 FM

As a reminder, both the AMSAT and now ARRL Field Day rules state only one 
completed QSO per FM repeater satellite. Please adhere to this rule so that 
others may have an opportunity to make a QSO. Also, all stations are asked 
to please only transmit when they can hear the satellite, and please use 
full duplex (with headphones) as a courtesy to the other users. Those 
stations planning on using circularly polarized antennas please remember the 
435.150 downlink is left hand circular polarization (LHCP), and the 435.300 
downlink is right hand circular polarization (RHCP). Stay tuned to AMSAT ANS 
bulletins or the AO-51 News page 
http://www.amsat.org/amsat-new/echo/ControlTeam.php for practice sessions of 
this mode to be scheduled several times between now and Field Day.

73 and Good Luck!
