Hi,
I'm a newbie for amateur satellite stuff, and I want to gain a deep
knowledge and experience in it.
I have a 2-meter band VHF transceiver handheld radio, and has 5 watt for the
output power. Can I use the radio to communicate with any satellites that
support VHF?
And please direct me to the resource that I need to start building my first
small station. Thank you in advance.
Cheers,

Your radio may work for listening and working the ISS, and if it has PL
tones it will work for an uplink to SO-50. Maybe a few other things too.
Take a look at the AMSAT web store for "Getting Started on the Amateur
Satellites". For a very modest donation, you'll get the best primer around.
Got a callsign yet?

It's very old and hard to find, but The Satellite Experimenters Handbook
by Martin Davidoff K2UBC will give you fundamental knowledge on
satellites, orbits, tracking, antennas, feedlines, etc. The book is
old, but the laws of celestial mechanics haven't changed.

You will need to operate on two bands, to work satellite. I can't think
of any satellites offhand that operate on a single band. You will use
one band to transmit TO the bird (uplink) and a separate band to receive
sigs FROM the bird (downlink).
Can you get some 70cm gear? If you can transmit/receive both VHF 2M and
UHF 70cm, you can operate Mode-B (70cm UPlink and 2M DOWNlink) or Mode_J
(2M UPlink and 70cm DOWNlink). Some birds operate FM, some use a linear
transponder for use with CW/SSB. It's *possible* to run FM through a
linear transponder but it's frowned upon because it hits the satellite
batteries harder, not to mention bogarts the passband.
Failing this, if you have an HF rig and know CW, you could try AO-7 via
Mode-A (VHF 2M up, HF 10M down). Put a key across the PTT line of an FM
rig, disconnect the mic (no modulation of the carrier) and you have a
poor-man's CW rig on 2M. Listen to your sigs and hopefully a few
replies on your HF rig.

Well, once you have gear for two bands, you will need antennas. A
rubber duckie is workable, but far from ideal. Popular these days are
small, hand-held yagis, of various designs. But you could experiment
with other designs, such as the quadrifilar helix, the turnstile, the
lindenblad, and so forth.
How do you wish to operate? Portable, from all over the place? From
your own back yard? Out of your shack?

IMPORTANT message for all those planning to attend the special tour to the
Orlando Science Museum during the AMSAT Space Symposium in Orlando, FL on
Sunday, Oct. 28, 2012.
For those planning to attend the special Star Wars Exhibit, you must contact
Martha at AMSAT, to pay for your ticket in advance. Martha can be reached at

If you
choose to visit this exhibit, you MUST contact Martha at AMSAT, and
pay for
your ticket in advance. Martha can be reached at 888-322-6728 or 301-589-
6062). This must be done no later than Thursday, October 17 to

will be
$27.00. Please note that this fee also covers general admission to
OSC and
all exhibits, including the IMAX theater. When you arrive the tickets
will be with
your tour guide.
? Those that choose not to attend the Star Wars Exhibit may have the
opportunity of attending a feature in the IMAX Theater, providing the show
times coincide with our time schedule during the visit. Admission to the
IMAX Theater is covered under your initial admission fee. Admission fee to
OSC will be $17.00 for those not attending the Star Wars Exhibit and will be
paid at the door.

All good information from Gus however I note as an exception that you
can work ISS Unproto Packet on 145.825 with a Single band FM radio and
single antenna...There are directions somewhere for an EZ homemade beam
that another might be able to pull out the link for.

Mike,
You are probably right. I'll also try my measurement method on
those satellites. But their AFSK signals are not so suitable for
this type of measurement. In this case your method works better.
If you look at the mean anomaly and argument of perigee in the
group of 2-line element sets for these Cubesats, you can see that
there are actually two groups: 38852 and 38856 (let's say group A)
and 38853, 38854 and 38855 (group B). We know that the Cubesats
were launched in two groups at different times and at different
points in the orbit of the ISS. This means that WeWish and Raiko
must be in group A and the other three satellites must be in
group B.
So if TechEdSat is 38854, WeWish is 38856 and FITSAT 1 is 38853,
then we can conclude that Raiko is 38852 and F 1 is 38855.
So to summarise the identifications for these Cubesats:
38852 = Raiko
38853 = FITSAT 1
38854 = TechEdSat
38855 = F 1
38856 = WeWish
Obviously this is only valid if the 2-line element sets are not
re-assigned again to different object numbers. This has happened
in the first days after the launch from the ISS and it may happen
again...

Hello,
Visiting the AO-27 website i see the following "Current AO-27 Status:
Primary Bootloader", also i read about N3UC asking to don't transmit if the
analogue mode is not heard.
Can someone help me with a little bit info? Has been it working in analogue
mode recently? I wan't to give it a try today, and also durind the next
weekend, but i guess asking first will be better to avoid interference.
So, any info about scheduled operations for the next two-three days will be
very appreciated.

Hi Nico,
yes, you're absolutely right. Swapping of objects (ever with small cubesats)
is not new and it happens again and again. We saw this also with the NROL-36
objects. So we have to wait some more days and make the analysis again.
