Dear AMSAT Member,
We would like to inform AMSAT members that they should be able to receive
telemetry transmissions from the JAISAT-1 satellite which is scheduled for
launching on July 5, 2019 by a Soyuz 2.1b rocket at 05.41 UTC together with
the Meteor M N2-2 satellite and along with a total of 34 satellites from 12
countries. for live at link: https://www.youtube.com/watch?v=cDbhjv_2UNM
JAISAT-1 There is a telemetry beacon with a downlink on 435.325 MHz The
telemetry signal formet is 4k8 GMSK Mobitex or same dstar one Sparro and
iSAT (CMX990 Mobitex Format)
in accordance with the details from the IARU satellite co-ordinator
according to the following link:
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=521
This is keplerian element from simulate orbit the following as below:
JAISAT-SIM
1 77777U 19001a 19186.41724769 .00000000 00000-0 00000-0 0 00015

All amateur radio operators capable of receiving signals from the JAISAT-1
satellite are invited to send the data by email to: jaisatonetele@?????.???
and the Radio Amateur Society of Thailand will have a SWL card to confirm
reception to everyone.
Sincerely and with respect.

Hi Nico,
Thanks for sharing the image links.
Has anyone from the LO-94 team submitted these images for APOD
consideration? Amazing accomplishment.

Patience. This is a particularly difficult day/time to get on an FM bird.
1. Holiday - Perfect for BBQ with Handheld and Arrow. So a Bajillion people
trying to use sats
2. Two different special events stations on
3. Rovers.
Be patient, pick your passes and you will do just fine.
Time your calls with the peak of your signal, it's an art and a science.

In addition to all the great advice so far, I think the answer (or problem)
could be in the technicality of using the Arrow.? It has been mentioned in
one of the AMSAT publications and few others, but consider this, if the
arrow is in phase with the downlink, the arrow's uplink is practically out
of phase, and you wouldn't be able to make it in.?? I struggled with this,
until I started keeping the arrow just out of the null of the downlink, then
everything was magical !?? Just another fun fact...?

Do not forget if you would like your groups score included in the 2019
Field Day summary, your submission must be made by 11:59 PM, Monday,
July 8, 2019. We are running a little behind last years submissions. I
even have our club in with our one contact. You do not have to have a
lot of contacts, any amount is respectable. It is the ooo's and ahhh's
that those watching said when they saw a satellite contact being made.

Don?t get discouraged! The 13 colonies stations made it tough today. I had
my 5w 817 and an arrow, and just had to be patient trying to make contacts
for the Amsat 50th event on the morning passes. Not every day is like this.

You could easily get on the linear birds with an existing HF rig and an
inexpensive transverter[1a][1b] for the uplink.
Downlink is easily handled with an SDR solution, ranging in price from
$7 to $500, depending on how many whistles you want. The rtl-sdr
dongles[2] are a cheap, easy path to get your feet wet.
If you are up for the challenge, building a 70cm DSB transmitter[3] is
quite feasible. If you have an rtl-sdr dongle, you've got a spectrum
analyzer to debug/tweak your design. There are a ton[4] of design ideas
on the 'net. Don't be afraid to experiment. That's what this hobby is
all about, and one only truly learns through error, not success.

Eh, what you describe might be inexpensive, but I wouldn't call that
easy. I already find it a pain to throw my 910H on top of my car and
connect everything to it and be anchored to my car. I much prefer my
FM setup which hangs on my shoulders and requires minimal connections.
What you describe has a LOT of components: HF radio, transverter, SDR,
computer, and all the cables required to connect all that together.
All to be assembled every time you want to operate, and disassembled
afterwards. Unless you're assuming some sort of base station, but then
what inexpensive/simple antennas will he use?
If he already has an Icom IC-706MKIIG, Yaesu FT-857D, FT-817, or
something similar, he could at least do half duplex linear, and if he
also has a Kenwood TH-D74, TH-F6A, or some other HT with VHF/UHF SSB
RX, he could do full duplex, with a lot less components. Even a 706
MKIIG + an SDR would be less complicated than the HF+transverter+SDR
setup you suggest.

Cheap, easy, fast. Pick any two. :-)
