 100vw, 277px»>The time when AO-73 enters continuous sunlight, for the first time, is fast approaching. Current estimates show that this will commence on February 6th and last through until March 13th.</p>
<p>Obviously, the autonomous switching system that the spacecraft has been using to switch between amateur mode, with the transponder on in eclipse and educational mode with high power telemetry only in sunlight, will no longer work.</p>
<p>Already the periods of eclipse are reducing quite rapidly and we are therefore planning for manual mode switching to take be undertaken. This will start from the week beginning Jan 21st and will follow this initial plan.</p>
<p>Wednesday evening (UTC) or Thursday morning – switch to full time amateur mode – ie transponder on with low power telemetry.</p>
<p>Sunday evening (UTC) or Monday morning – switch to full time educational mode with high power telemetry only.</p>
<p>So if you are planning school demonstrations or particular DXpeditions please take this new schedule into account.</p>
<p>The team may have to flex this plan with experience as this situation was not allowed for in the original mission plan!</p>

CubeSats carrying amateur radio payloads were among the 31 satellites successfully launched on January 12 at 0359 UT on an Indian ISRO PSLV rocket.
Two of the CubeSats, Fox-1D and PicSat, carry amateur radio FM transponders, but neither is yet available for general amateur use. The PicSat FM transponder is unusual in that instead of a CTCSS tone it requires a 1750 Hz tone burst to activate it. The 1750 Hz tone burst used to be popular on IARU Region 1 FM repeaters in the 1980s and 90s before the widespread use of CTCSS.
CNUSail-1, built by students at the Chungnam National University in Korea, carries a deployable sail. The students have requested the help of radio amateurs in receiving the 437.100 MHz beacon, further information is available at https://sites.google.com/view/cnuusg
JE9PEL lists these frequencies for the satellites carrying amateur radio payloads:
Fox-1D (AO-92) 145.880 down 435.350/1267.350 up FM CTCSS 67.0Hz/200bps DUV PicSat 435.525 1200bps BPSK CNUSail-1 437.100 9600bps GMSK Canyval-X 1/2 437.200 9600bps MSK KAUSAT-5 437.465/2413.000 9600bps FSK,115k2 MSK STEP-1 437.485 9600bps FSK CW
Shankar A65CR/VU2SWG reported coping the Fox-1D satellite voice beacon on the morning pass at 30 deg elevation in Dubai using a TH-F7 with standard rubber duck. YL voice with satellite identifier. Very short burst with fluctuating carrier.
Madhu A65DE also copied Fox-1D from Fujairah, North of Dubai.
AMSAT North America has issued a statement formally designating Fox-1D as AO-92:
Fox-1D, a 1U CubeSat, is the third of AMSAT’s five Fox-1 CubeSats to reach orbit, being preceded by AO-85 (Fox-1A) and AO-91 (RadFxSat / Fox-1B). Fox-1D carries the Fox-1 U/v FM transponder, with an uplink of 435.350 MHz (67.0 Hz CTCSS) and a downlink of 145.880 MHz. In addition, Fox-1D carries several university experiments, including a MEMS gyro from Pennsylvania State University – Erie, a camera from Virginia Tech, and the University of Iowa’s HERCI (High Energy Radiation CubeSat Instrument) radiation mapping experiment. Fox-1D also carries the AMSAT L-Band Downshifter experiment which enables the FM transponder to be switched to utilize an uplink of 1267.350 MHz (67.0 Hz CTCSS).
Fox-1D was sent aloft as a secondary payload on the Indian Space Research Organisation (ISRO)’s PSLV-XL rocket as part of the PSLV-C40 mission. Fox-1D was one of thirty-one satellites successfully deployed on this launch.
Since Fox-1D has met all of the qualifications necessary to receive an OSCAR number, I, by the authority vested in me by the AMSAT President, do hereby confer on this satellite the designation AMSAT-OSCAR 92 or AO-92. I join amateur radio operators in the U.S. and around the world in wishing AO-92 a long and successful life in both its amateur and scientific missions.
I, along with the rest of the amateur community, congratulate all of the volunteers who worked so diligently to construct, test and prepare for launch the newest amateur radio satellite.

AMSAT-NA OSCAR Number Administrator
