The event will run from approximately 1600 UTC 02 Jan to 0345 UTC 03
Jan. We ask that all amateur radio stations give this short time window
to promote satellite operations with kids. If not actually showing a kid
how to make contacts via AO-51, then providing a station to contact, or
stepping aside to allow others to make contacts with the kids. During
the event please limit contacts to stations that are operating with kids
at the microphone.

AO-51 ECHO LOW POWER STATION (QRP) REQUIRMENTS:
To attempt to keep this simple a low power station will be defined as a
station which can deliver no more than 10 watts to a vertical or
handheld
antenna.
Some examples of Low Power Stations:
1) Using an HT (barefoot, no amplifier) with 10 watts or less output
into
any type of vertical whip antenna (rubber duck, etc) or handheld beam
antenna (arrow type).
2) Using a mobile station with 10 watts or less output into car mounted
mobile whip antenna(s).
3) Using a base station at 10 watts output into a vertical
omnidirectional
antenna on the side of the house.
Examples that are NOT Low Power Stations:
1) Any type of high gain beam antenna, KLM, M2, Cushcraft, etc.
2) Any station transmitting over 10 watts into any type of antenna.
How well we operate the satellite within these guidelines will determine
how much we can run this mode in the future. So lets try and do this
right!
