one per transponder on a single channel fm satellite. as two transponders are active, you can make one contact on v/u and one on l/u.

Drew, Would the "one QSO per satellite" rule apply for each channel of AO51? Or is it just one QSO for the bird, period?

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! Drew KO4MA AMSAT VP Operations
