Hurricane Dennis may alter AO-51 schedule

The July AO-51 schedule has been posted on the AMSAT Web site www.amsat.org.

The mode change on July 11 may not occur on schedule due to Hurricane Dennis' expected path, which is coming right for AMSAT's command operator and station, Mike, KE4AZN. Please understand if that change is delayed by a number of days. Based on the projected path, Mike will be taking down his antennas and will be securing everything at his QTH on Saturday.

July 2005 AO-51 (Amsat Echo) Schedule

All dates are UTC. The mode change occurs normally between 0100 and 0400 UTC on the date shown. The mode will be active from the date shown until the next Mode Change date listed. Mode Configurations are listed below the schedule. If for some unplanned reason we need to work with Echo and deviate from the plan a note will be posted to the this Echo page on AMSAT.ORG.

If a specific transmitter or mode is not listed on a given day then it will be off. For example, if TXB (435.300) is not listed during a 38k4 digital mode period then the FM repeater will be off.
