Dayton Hamvention AMSAT Demonstration Plans

AMSAT will again have a demo station at the Dayton Hamvention this year. The station will be located outside the main entrance to Ball Arena, near the AMSAT booth.

This year, the focus of many of the demonstrations will be on the use of inexpensive software defined radio (SDR) equipment as a downlink receiver. Using an SDR like a FUNcube Dongle Pro+, SDRPlay, or AirSpy allows owners of common all-mode transceivers with VHF/UHF functionality (such as the Yaesu FT-817, Yaesu FT-857, Icom
IC-706MKIIG, or Icom IC-7100) to add full duplex satellite capability for use with linear transponder satellites at minimal cost. The receiver used will consist of a FUNcube Dongle Pro+ with a low cost 10.1″ Windows 10 tablet.

We may also use other radio combinations during the weekend.

Demos will take place during satellite passes from 8:00am (12:00 UTC) until 5:00pm (21:00 UTC) on Friday and Saturday and from 8:00am until 12:00pm (16:00 UTC) on Sunday. Please keep in mind that the RF environment at the Hamvention is challenging and the arena blocks low elevations to the north and northwest. Due to these factors, we will only be attempting passes with a peak elevation greater than 10 degrees. Please stop by for any satellite pass or at any other time if you have questions about satellite operating.

A special demonstration on SO-50 will take place during the 12:19pm (16:19 UTC) pass on Saturday May 21st. Nine year old Hope Lea, KM4IPF, will operate that pass after completing her talk at the ARRL Youth Forum.

If you are not attending the Hamvention, please call us if you hear the AMSAT demo station on the air!

CY9C DXpedition to St. Paul Island Announces Satellite Operation

The CY9C DXpedition to St. Paul Island, scheduled for August 19, 2016 – August 29, 2016, has announced that Lee Imber, WW2DX, has joined the DXpedition team and will add satellite operations, as well as 2 meter EME and 6 meter operations, to the DXpedition plans.

St. Paul Island is located in gridsquare FN97 in the Cabot Strait between Cape Breton Island, Nova Scotia and Cape Ray, Newfoundland and is a separate entity on the ARRL DXCC list. It also counts as a country for the AMSAT OSCAR Satellite Communications Achievement Award, AMSAT OSCAR Sexagesimal Award, and AMSAT OSCAR Century Award. Most of Europe and North America should be easily workable from this location. St. Paul Island has not been activated on satellite since July 1998.

For further information about the DXpedition, please see the CY9C DXpedition website.

This operation and other planned amateur satellite grid/DX operations are posted on the AMSAT Upcoming Satellite Operations page.

ÑuSat-1 to Carry AMSAT Argentina Linear Transponder – Launch Scheduled for May 30, 2016

The Argentinian earth observation satellite ÑuSat-1 will carry a linear transponder built by AMSAT Argentina. The satellite is scheduled to launch on a CZ-4B rocket from Taiyuan Satellite Launch Center in China on May 30, 2016 into a 500 km sun-synchronous orbit with an inclination of 97.5 degrees and a Local Time of the Ascending Node (LTAN) of 10:30.

The AMSAT Argentina U/v inverting transponder, named LUSEX, wiil have an uplink of 435.935 MHz to 435.965 MHz and a downlink of 145.935 MHz to 145.965 MHz. Total power output is 250 mW. There will also be a CW beacon at 145.900 MHz with a power output of 70 mW.

For more information, see the AMSAT Argentina Facebook group.

UPDATE:  A website with preliminiary Keplerian elements and further information is now live at http://lusex.org.ar/

From Stefan Dombrowski, ON6TI: 

OUFTI-1, the first D-STAR repeater in space, is currently on the launchpad in Kourou, French Guiana. The launch is scheduled for Monday, April 25th at 21:02:11 UTC.

On board this Fregat flight, VS14. are Sentinel-1B, Microscope, Norsat-1 as well as 3 cubesats participating at ESA’s “Fly Your Satellite” programme. Those 3 cubesats are:

AAUSAT-4 is an initiative of the University of Aalborg, Denmark and will have as primary payload an AIS receiver to allow tracking of ships. AAUSAT-4 will transmit on 437.425 MHz using CW and the CSP spacelink format. Further information is available on the homepage http://www.space.aau.dk/aausat4/

e-st@r-II is an initiative of the University of Turin, Italy and will transmit a CW beacon on 437.485 MHz. More information is available at http://www.cubesatteam-polito.com/operations/radio-amateurs/

Finally, OUFTI-1 is a cubesat designed at the University of Liège, Belgium. One of its payloads is a complete D-STAR repeater. The initial mode will be a CW beacon on 145.980 MHz. Technical details and the software to decode its telemetry can be found on http://events.ulg.ac.be/oufti-1/radioamateurs/
The CW beacon will transmit periodically for 2 minutes followed by 1 minute of silence.
The AX25 beacon will be turned on later, once the attitude of the satellite has stabilized.
Following timing is expected on Monday, April 25th:

Launch: 21:02:11 UTC (you can watch this live on http://www.esa.int/spaceinvideos/esalive)
Separation: 23:50:24 UTC
Activation: 00:20:24 UTC (Tuesday)

OUFTI-1 and e-st@r-II will start transmitting just in reach of Mexico. 1st pass over the US will be a few minutes later, covering around 00:32:00 UTC the whole US with a very high elevation. The next pass around 02:00:45 UTC will benefit the western half of the US.

The preliminary TLE’s for all 3 cubesats are
