Hi Nick.
My suggestion would be to have a look at the SPF5043.
http://eu.mouser.com/ProductDetail/RFMD-Qorvo/SPF5043Z/?qs=p6lVfQR1GSoUob90DTn
CEA%3D%3D
Probably a little more than 10mA, but a nice device. Needs a good LPF as it
has gain from 50MHz to 4GHz
Thanks
David G0MRF
The satellite team at the University of Louisiana is look for a VHF preamp
design to fly in a sat. The amp should have
1. Gain > 20 db
2. NF < 1 db
3. DC volts 3.3 vdc
4. Current ~ 10 ma
Any help is appreciated

Thank you all so much for such prompt replies!! I am happy to say that we
have recieved news of beacon reception from various sources and this can
confidently say that the satellite is active an finctioning! Though we
havent been able to hear anything on our ground station but are trying
regularly for the same. We request you all to kindly keep tracking our
satellite and if possible try receiving the downlonk telemetry with the
following specs:
Modulation: FSK
Frequency: 437.455 MHz
Transmitted power: 60 mW
To be switched on over India and France
Please do reply to us if you receive anything. We really appreciate all
your help. Thanks a lot.

Kind regards,
Team Pratham.

Gearing up for a VP5 visit and operation Oct. 16 - Nov. 2. Will be part of
VP5DX CQWW SSB team but still have time for portable SAT operations. I
worked 9 stations in a practice run from the University of Florida campus a
few weeks ago. I should be able to operate SATs from Oct. 19-28.
Equipment will be a FT-817 and arrow II. Will also have a TH-D7A as a
backup for the FM birds. Practice runs were on AO-73 and FO-29 using the
FT-817.
I will have another practice day on Sunday Oct. 9th. Please mark your
calendar and work me that day from EL-89tp. My signal will be readable but
not strong, which I am sure you will not mind when I am the DX station you
are chasing. I will use that day as a teaching experience for the Gator
Amateur Radio Club student members. You can see photos from our last event
on their Facebook page. Feel free to friend me as well.
I have been told it has been ten years since there has been a SAT operation
from VP5. My operation will not be from Provo (FL31) but from Middle
Caicos (FL41cu). Check out the QTH on the VP5DX QRZ page. Do any AMSAT
members have FL41 in their log?
Looking forward to working you from FL41cu.

About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the Center for the Advancement of Science in
Space (CASIS) and National Aeronautics and Space Administration (NASA).
The primary goal of ARISS is to promote exploration of science, technology,
engineering, and mathematics (STEM) topics by organizing scheduled contacts
via amateur radio between crew members aboard the ISS and students in
classrooms or informal education venues. With the help of experienced
amateur radio volunteers, ISS crews speak directly with large audiences in a
variety of public forums. Before and during these radio contacts, students,
teachers, parents, and communities learn about space, space technologies,
and amateur radio. For more
information, see www.ariss.org, www.amsat.org, and www.arrl.org.
Thank you & 73,

I was not sure yesterday evening, with MOVE-1, Duchifat and AO-73 all
around, but no doubt, PRATHAM is definitely alive. Congratulations !
The CW speed is fairly high, a little bit chirpy, all as we like. No
? :-) As I decode with my poor little human ham ears, I don't know
exactly, but I would say 40 wpm, something like that. A piece of my
record of the pass over western Europe, orbit nr 43 this morning at
about 1030 UTC, is here (with a GPA in the attic, the good old FCD-Pro+,
Debian-Linux, Gqrx/GPredict):
http://f5yg.pagesperso-orange.fr/incoming/PRATHAM_orb43_29sep2016.mp3
text is, of course, "VU2BUG PRATHAM IIT BOMBAY STUDENT SATELLITE"
repetitively.
The 2016-059C tle was used to compensate the Doppler drift and, as
you can hear, it's still not so accurate for the moment. But anyways...
Have a nice day, 73 !

I, JE9PEL received the very weak Pratham CW beacon on 29 Sep 2016.
Because I was not able to be imaged these fast speed signal, I have to
cooperate imaging to JA0CAW. So I confirmed to be a signal from Pratham
in the figure below.

Connect AGW Online Kiss (http://www.dk3wn.info/software.shtml) via tcp

Good luck and let me know if you have any further questions.

I've recently joined this group and I want to thank the moderator for
allowing me be here. I have been reading lots of threads as I am on a Sat
diet lately. My first Qs were done recently from YN land this past summer
and mainly using SO-50 (thanks to those who've made it possible). Now I am
all thirst for more :)
The wait is over....My new Leo-Pack arrived on yesterday! I am looking
for any tips on the setup of it, or mainly, what should I watch for.
I opened the box to spread the parts out and ...
- It is not like setting up a A4S or F12 10-40- Took me a few minutes to
decipher the Dimension Sheet - Realized the need to were globes...I got that
aluminum dust on my hands- Downloaded a English to Metric software to
convert the inches into metric (it is easier and more precise)
This antenna will go on top of an existing F12 (at roof top) using Yaesu
G-5500 with other plug and play devices. LMR600 coax 60' x 2 attached to
rig FT-847 / SatPC32 / Orbitron, etc.
I was told my Robert at M2 to place it 5' higher than the F12 and to hope
for the best :( Here in DC towers are no-no.
Again, thanks for any tip anyone can provide. My email...

I'm going to do a mini grid expedition Friday Sept 30 on the FN13/14
line, only the following passes:
FO29 at 1456, 1639 & 1829,
AO-7 at 1709,
SO-50 at 1857
Note: I will be calling KI4RO at the beginning of the SO-50 pass.
Please give him some room, then I'll work as many others as conditions
permits.
Thanks and 73,
Ken Alexander

All,
Detailed doppler measurements show that Pratham is object 41791,
2016-059J.
This is based on the most recent TLE sets, that were published by
the JSpOC. Unfortunately the collection of TLE sets for the PSLV-C35
launch is not stable yet. The JSpOC continues to cross-tag TLE sets
and to make major changes to some of the TLE sets. So some further
changes may be expected in the coming days.
The JSpOC has not yet identified any of the objects from the PSLV-C35
launch. It seems quite obvious however that ScatSat is object 41790,
2016-059H.
73,

It appears that AO-7 switched to Mode A between 0400 and 0600 UTC today.
That suggests that the satellite is now in constant sunlight and receiving
enough power from the solar cells for the 24 hour timer to stay on
throughout it's entire orbit. Expect daily mode switches between A and B to
occur for the next three months or so.
As AO-7's orbit precesses and the periods of constant sunlight become fewer
and fewer, there will be less of an opportunity to use Mode A on a yearly
basis, so enjoy it while it lasts!
If you don't have a 10 meter antenna up to receive the downlink, try
whatever you can. I have used my AlexLoop Walkham Portable Magnetic Loop
with adequate results.
