Reception of AubieSat-1 at K5QXJ
John Klingelhoeffer, WB4LNM, AubieSat-1 Technical Mentor at Auburn University Alabama reports that the satellite has been successfully commanded to change the transmission mode.
John says “A short message was received Saturday evening indicating that uplink commands sent to AubieSat-1 were properly received, decoded, and initiated additional telemetry downlink data. AS-1 has been in orbit for about 9 months. Stations are asked to continue to monitor the downlink and pass any received telemetry to the group here for dissemination.”

AubieSat-1 was launched from Vandenberg AFB, California in October, 2011. The CubeSat is an undergraduate built satellite developed by Auburn University. Over the weekend of June 9-11 the AubieSat-1 controllers changed the transmission mode of the satellite to increase the quantity of telemetry. The increased telemetry rate will provide data to indicate how well solar cell protection is working. It should also provide additional onboard housekeeping information.
AubieSat-1 transmits with a power of about 800 milliwatts on a frequency of 437.475 MHz. The beacon signal, along with telemetry, is sent using A1A continuous wave Morse code at 20 words per minute. Additional telemetry from the onboard science experiment will use CW transmissions up to 60 WPM.
