AMSAT NEWS SERVICE
ANS-109

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
satellites.

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.

Fox-1C and Fox-1D Include L-Band Uplink; Fox-1E Linear Transponder Announced

AMSAT Vice President - Engineering Jerry Buxton, N0JY, announced plans to
incorporate an L band receiver in Fox-1C and Fox-1D. The addition will allow
ground commanded selection of the U/v (normal Fox-1 bands) or the new L/v
1.2 GHz (23 cm) mode. Both bands will operate as FM single channel.

Rather than adding a complete new receiver, the L band "Project Downshifter"
will convert the received L band signal down to the Fox-1 uplink frequency
and feed it to the regular UHF receiver on the Fox-1 satellite. The design
will not require an additional antenna on the satellite because the existing
UHF antenna will work for L band receive as well.

In concert with the development of the satellite segment, a new group of
volunteers is working on a companion uplink station to convert UHF to the L
band uplink frequencies:

+ Bruce Herrick, WW1M
+ Dan Hubert, VE9DAN
+ Elizabeth Schenk, KC1AXX
+ Dave Smith, W6TE
+ Alfred Watts, AF5VH

The team is planning to have an affordable L band uplink ground station
available to amateurs by the time Fox-1C is on orbit.

In further news, Jerry announced the plan to construct a Fox-1E "Evolution"
variation of the Fox-1 series which will carry a Mode J linear transponder.
The transponder is planned to be 30 kHz wide and will also include a 1200
bps BPSK telemetry beacon. The purpose of the project is to test a 
design for a
linear transponder that could be made available to CubeSat builders as a
secondary, or even primary radio payload thus bringing more 
opportunities for
amateur radio in space as well as offering AMSAT's proven communications 
skills
as a telemetry option.

AMSAT has been approached for a launch opportunity for Fox-1E in 2016, but
launch details can not be shared at this time.

Jerry concluded, "It is important that we find additional resources to help
the Fox-1 Team with these new endeavors. We are looking for volunteers who
have solid RF building and testing experience to work on both the
downshifter and the transponder prototyping and construction." If you would
like to help and be a part of the success of Fox-1C/D and Fox-1E, please
contact Jerry through the AMSAT Engineering volunteer form page on-line at:

Immediate Volunteer Opening at AMSAT: Cubesat Thermal Engineering

AMSAT Vice President - Engineering Jerry Buxton, N0JY, says he has an
immediate need for a volunteer who is experienced in thermal engineering.
Opportunities include upcoming AMSAT CubeSats up to 6U in LEO and HEO, and
larger spacecraft up to 150 kg.

Jerry says Sinda, Thermica, and Patran software experience would be helpful.

If you would like to help and be a part of the success of Fox-1C/D and
Fox-1E, please contact Jerry through the AMSAT Engineering volunteer form
page on-line at:
http://ww2.amsat.org/?page_id=1121.

AMSAT at the Dayton Hamvention -- Second call for volunteers

The Dayton Hamvention is less than five weeks away!

It is time to be creating your shopping list and making your travel plans.
  If you can stay for more than a day and you want to stay at the AMSAT
hotel, contact Martha ASAP.

Last year, we had 52 people assist with the AMSAT booth at Dayton. We've
had a good response so far to our call for volunteers, but we could really
use another 10-15 people.

The interaction with AMSAT members, satellite operators, designers, and
builders makes the whole experience a lot of fun.  Meet or renew
acquaintances, exchange operating tips, and find out what antennas,
software and equipment other AMSAT members use.   We currently expect all
of the AMSAT senior officers and 5 of the 7 board members to be there too.

The 2015 Hamvention is May 15-17.  Would you consider helping AMSAT at
Dayton this year?

If you're an experienced operator, great!  We can use you and your
experience.

If you've never operated a satellite before, but want to learn more,
that's OK.  We can use your help too.

Whether you're available for only a couple of hours or if you can spend
the entire weekend with us, your help would be greatly appreciated.

Please send an e-mail to Steve, n9ip ＠ amsat.org if you can help. Thank you!

Clive Wallis – G3CWV – SK

 From Jim Heck, G3WGM, Hon Sec AMSAT-UK

It is with great sadness that I have to inform you that I have just 
learnt of
the passing of our dear friend Clive Wallis, G3CWV on 27th March 2015.

Clive has been a very staunch supporter of AMSAT from the very early 
days. Many
will recall his intense interest and loyalty in following UOSAT-2/UO-11. He
maintained a very comprehensive web site with details of the spacecraft’s
activities. He wrote many articles for Oscar News about his activities. He
attended many AMSAT-UK Colloquia.

For 17 years between 1996 and 2013 Clive produced monthly reports on 
OSCAR-11
(UoSAT-2).
The report archive is at http://www.g3cwv.co.uk/newsarch.htm

Clive’s OSCAR-11 page http://www.g3cwv.co.uk/oscar11.htm

In 1993 Clive Wallis G3CWV took over distribution of satellite related BBC
software
http://amsat-uk.org/2011/12/11/bbc-micro-and-amsat-uk-software-library/

He was awarded the Louis Varney cup for 2015 by the RSGB, and although 
he knew
of the award before his passing, the formal presentation is not until 25 
April.

His funeral is to be held on Tue 22 April 2015 at 3.00pm at Christchurch,
Bedford Road, Hitchin, Herts, UK. I am sure that his family would 
appreciate the
presence of any AMSAT members who are able to be there.

We send our condolences to his widow, Janet.

RIP, Clive.

Cayman Island on Satellites May 20-25

ZF2, CAYMAN ISLANDS. Operators Pete/N8PR and Bill/NZ5N will be active as
ZF2EM from the Cayman Islands between May 20-25th. Main activity will be
focused on 2 meter EME, but with some HF SSB and maybe JT65HF. They will
also have 2m/440 and an Elk antenna for some possible FM satellite QSOs
if the passes are at times when the moon is not up. QSL via N8PR.
