AO-51 repeater mode to support JOTA operations
AO-51 Command Station Mark Hammond N8MH, said that the AO-51 Operations Team will configure the satellite to support the Jamboree-On-The-Air (JOTA) for Scouting
AO-51 FM Repeater, V/U
Uplink: 145.880 MHz FM (no PL tone)
Downlink: 435.150 MHz FM
No transmitter power or antenna restrictions usually associated with the QRP mode of AO-51 operation on this repeater apply to JOTA stations. Use good amateur practice during your operations.
Non-scouting users are asked to use 10 watts or less, and omni-directional or handheld antennas on this repeater. Last minute schedule changes may be required due to the power budget aboard AO-51. Also non-scouting stations please give way to JOTA stations or QSOs with JOTA stations
The 2010 Jamboree-on-the-Air, or JOTA, will begin on Saturday, October 16, 2010, at 00:00 hours local time, and end on Sunday, October, 17, 2010, at 23:59 hours local time.
This is an annual Scouting and amateur radio event sponsored by the World Scout Bureau of the World Organization of the Scout Movement. Thousands of amateur radio stations around the world participate.
In the United States, Cub Scout dens and Boy Scout patrols visit a local amateur's ham shack during JOTA. Amateurs set up stations giving Scouts and leaders a chance to exchange greetings with Scouts from other areas. The exchanges typically include information such as Name, QTH, Scout rank, Hobbies, and Age. Full details from the World Scout Bureau can be found on-line at:

Scouts and Amateur Radio operators may also find the ARBONET III high altitude balloon launch for JOTA interesting. ARBONET has published full details of their mission on-line at:
