The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT North America, The Radio Amateur Satellite
Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio

The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.

Please send any amateur satellite news or reports to:
ans-editor at amsat.org.

2015 AMSAT-NA Board of Directors Nomination Deadline Approaching

It is time to submit nominations for the upcoming AMSAT-NA Board of
Directors election. Four director's terms expire this year: Barry Baines,
WD4ASW, Alan Biddle, WA4SCA, Mark Hammond, N8MH, and Jerry Buxton, N0JY. In
addition, up to two Alternates may be elected for one year terms.

A valid nomination requires either one Member Society or five current 
members in good standing to nominate an AMSAT-NA member for Director. 
nominations, consisting of the nominee's name and call, and the nominating
individual's names, calls and individual signatures should be mailed
to: AMSAT-NA, 10605 Concord St, #304 Kensington, MD 20895-2526. In 
addition to
traditional submissions of written nominations, which is the preferred 
the intent to nominate someone may be made by electronic means. These 
include e-
mail, Fax, or electronic image of a petition. Electronic petitions should be
sent to MARTHA @ AMSAT.ORG or Faxed to (301) 822-4371. No matter what means is
used, petitions MUST arrive no later than June 15th at the AMSAT-NA 
office. If
the nomination is a traditional written nomination, no other action is 
If it is other than this, i.e. electronic, a verifying traditional written
petition MUST be received at the AMSAT-NA office at the above address 
within 7
days following the close of nominations on June 15th.

Nick Lance, KC5KBO, SK

On  behalf of the ARISS-International team, it is with great sadness that
we announce the passing of long-time ARISS team member Nick Lance, KC5KBO,
SK.  Nick passed away on May 24 from an aneurism of the aorta.
Nick was  a smart, caring, considerate and helpful person that loved the
amateur radio  hobby.   As the primary amateur radio license trainer for the
ISS  astronauts, Nick played an integral role in encouraging and training
countless  astronauts (US, Canada, Japan and Europe) to pursue their amateur
radio license  and become active on ARISS.  He inspired and trained 
dozens of
NASA's  aerospace education specialists (who talk to schoolteachers
nationwide) to get  their ham tickets. He also taught a "Hamster" course to
middle schoolers, inspiring them to pursue careers in technology through 
Radio and ARISS  activities.

Personally, I enjoyed working with Nick both as a NASA  engineer and an
amateur radio operator.  I will miss his quick wit and  sense of 
humor.   Nick
will be deeply missed by many.

A Celebration of Life for Nick Lance will be held Sunday, June 14, 2015,
2 p.m. at the Gilruth Center. A map to the public entrance of the Gilruth
Recreation Center, Building 207

A flag will be flown over Mission Control and presented to Renee and the 

Our deepest  sympathy goes out to all that knew Nick, especially Renee, his
wife, and all his  family members.

Update - VP2MKV Satellite Operation June 11-20

Operators Barry/N0KV, Ken/W0ETT, Greg/W0ZA and Jim/WD0E will be active as
VP2MKV from Gingerbread Hill, St. Peters (grid square FK86), between June
10-18th. Activity will be on 80-2 meters using CW, SSB and RTTY. They will
also participate in the ARRL VHF Contest and some satellite operations
(FO-29 only on selected passes). The two primary radios will be Elecraft
K3's with 500 watt amplifiers. Antennas include a Mosley Classic 33 on
10/15/20, a folding hexbeam by Folding Antennas (Germany) on 20-10 meters,
verticals on 30 and 40 meters, a dipole on 75-80 meters, and an M2 5 element
6 meter beam. They will run 500 watts on 6m SSB/CW and FSK441. A 6 meter
beacon is planned and will be on 50.102 MHz when the station is not manned,
and the receiver will be active between beacon transmissions to listen for
calls. The primary callsign for the operation will be VP2MKV, and VP2MTT
will probably be used on 6 meters. Near 24 hour operation is planned.

Tentative satellite pass plan for VP2MKV operation: They will attempt to be
on the first two FO-29 ascending node passes June 11th through 20th. If time
allows they may be on the third ascending node those days. Those passes
happen in late morning to mid afternoon Montserrat time. On those passes
they will look first for South America when the satellite is south of them,
then North America, then Europe during the short mutual window. If there are
2 meter or 6 meter terrestrial openings during the VHF contest June 13th and
14th, they will not be on satellite at those times.

Logs will be uploaded to LoTW soon after the group returns to the US. Paper
QSLs via N0KV, direct or via the bureau. US addressees send SASE; addressees
outside the US send SASE plus 2 USDs for return postage. Use of ClubLog has
not been finalized at this time. Additional information will be posted under
VP2MKV on QRZ.com.

Planetary Society's LighSail Satellite Stops Transmitting

Excerpt from the Planetary Society's page http://planet.ly/0gVop
As of late Friday afternoon, LightSail was continuing to operate 
normally. The
spacecraft’s ground stations at Cal Poly San Luis Obispo and Georgia 
Tech were
receiving data on each pass. Power and temperature readings were trending
stably, and the spacecraft was in good health.

But inside the spacecraft’s Linux-based flight software, a problem was 
Every 15 seconds, LightSail transmits a telemetry beacon packet. The 
controlling the main system board writes corresponding information to a file
called beacon.csv. If you’re not familiar with CSV files, you can think 
of them
as simplified spreadsheets-in fact, most can be opened with Microsoft Excel.

As more beacons are transmitted, the file grows in size. When it reaches 32
megabytes-roughly the size of ten compressed music files-it can crash 
the flight
system. The manufacturer of the avionics board corrected this glitch in 
software revisions. But alas, LightSail’s software version doesn’t 
include the

Late Friday, the LightSail team received a heads-up warning them of the
vulnerability. A fix was quickly devised to prevent the spacecraft from
crashing, and it was scheduled to be uploaded during the next ground station
pass. But before that happened, LightSail’s automated chirps fell 
silent. The
telemetry data is sent on a downlink of 437.435 MHz, AX.25, 9600 bps 
FSK. The
last data packet received from the spacecraft was May 22 at 21:31 UTC 
(5:31 p.m.

29 MHz – the forgotten frequency for amateur radio satellites

Hans van de Groenendaaal ZS6AKV writes in the EngineerIT magazine about the
potential for 29 MHz as a satellite uplink band.

Universities and other scientific research institutions are using 
portions of
the amateur spectrum for their CubeSat’s which has caused the 145 and 
435 MHz
amateur-satellite band segments to be very crowded, leading to an increasing
number of satellite builders to explore alternatives.

For many, such as those requiring single-channel bandwidth greater than
approximately 12.5 kHz, the best answer will be found in the microwave 
However, for those who can use it, the International Amateur Radio Union 
satellite frequency coordination process has now opened another 
alternative: 29
MHz uplinks.
