AO-51 schedule for September

Drew, KO4MA, AMSAT-NA Vice President of Operations described the AO-51 Satellite Schedule for September.

Drew said, "We are currently running 370 mW on TXA (435.150) and 630 mW on TXB (435.300). Power levels will
continue to increase as eclipses get shorter, leading up to 10 weeks of continuous sun in early 2008."

Drew continued, "These are going to be interesting times. Keep in mind that anytime we have something other than telemetry running on TXA (i.e. L/U repeater), we may have to interrupt it occasionally for telemetry and satellite maintenance. Our lead command station, Gould WA4SXM,
has been doing an outstanding job of squeezing every last drop of power for the downlinks."
