Yes I use that also. For Transmit.
I was using FL-Digi for recv, but the single channel I know I was
missing people calling me.
I tried some of the others that use a multi trace capability. but wasn't
too happy with it.
But just now tried ACDS, and was quite impressed on it's working. The 34
seperate ummm channels or passbands? anyway,the being off freq, or freq
sweeping too fst will not it seems to be a problem with that program.

I am just curious.
For those of you active on NO-84, The PSK-31 Machine part, I am curious
as to what you are are using for stations?
10 meter Transmitter?
10 Meter Antenna
10 Meter transmit power
435 reciever
435 ant
435 pre amp?
Rec software using?
What is your level of success on NO-84 with the above setup,
And what would you change if you were to change anything?

Hello.
I have heard Yuri on AO-07B at 17:47 TU. His signal was very low and in the
noise, I have call him, and I think he respond me but I?m not sure. I
haven?t his locator.
Somebody have heard Yuri on this pass ?

Hello All;
an update from our good friend Jari, OH2FQV in Helsinki:
He reported on Twitter that Yuri, UT1FG, would be departing today & that he
had gotten the needed coax and stuff needed to set-up his ship board
station. I believe he said give a week to get everything installed.
The reported speed of the CHESTNUT appears to be slower than previous ships
he has been on so the crossing time may be longer than we have seen in the
past.
The "night-shift" begins soon!
Good Luck All & Good SatDX!!

I don't know of any such list but I do visit the AMSAT status page from
time to time to see calls that might be working the birds in recent
history. I also listen for those calls on close passes.

Now that I have managed to convert to the LVB tracker I find myself with two
Trak Boxes. If any one is interested in giving them a home other than on my
"I'm not using this any more shelf" e-mail me.
Never could get the LVB to work with the suggested Yaesu GS-230 selection.
Always got a note saying TLE-new.exe not found. However did get it to run
almost perfectly when I selected Saebert box. I did the calibration
procedure several times. However when I selett 179 degrees it comes up short
about 30 degrees. By the time I get over to 270 it is correct.

After having been off the satellites for a while due to life stuff, I am
almost ready to get back on again, I hope. I have a little space on the
mast under my miniquad where I can mount a small dualband end mounted
yagi. I have been looking at the Jetstream 2m/70cm since it is cheapest
and should fit there fine. It has 3 elements on 2m and 5 elements on 70cm.
Will that good enough on the satellites? I have used a Cushcraft 5/5
dualband yagi before with good results.
I hope in another year or so to have the parent's estate finally settled
and money for a real satellite station again, but am hoping this will do in
the meantime. Anyone else tried a yagi this size?

Get Your Iridium Fix Before It?s Too Late!
The shock and dazzle of Iridium flares will soon be a thing of the past.
Here's
how to make the most of seeing them before a new generation of spacecraft
replaces the Iridium satellites.
Each of the approximately 66 Iridiums in orbit have three door-sized
aluminum
antennae treated with highly reflective, silver-coated Teflon for
temperature
control.
When the angle between observer and satellite is just right, sunlight
reflecting
off an antenna can cause the satellite to surge from invisibility up to
magnitude ?8.5 in a matter of seconds. If you've never seen one, the searing
brilliance may make you recoil instinctively. On rare occasions, flares can
reach magnitude ?9.5. That's 100 times brighter than Venus!
Sadly, that era will soon draw to a close. On January 14th, SpaceX?s
Falcon 9
delivered the first 10 of a new generation of Iridium NEXT satellites to
low-
Earth orbit, starting the process to replace the older units in a maneuver
called slot-swapping. While the new birds will provide faster data rates and
enhanced global communications, their antenna design is completely
different and
not expected to produce significant flares.
Heavens Above is one of the easiest sites to get you looking in the
right place
at the right time. The Heavens Above website allows for easy figuring and
finding of Iridium flares.
Just sign in and give it your location, then click the Iridium Flares
link under
the Satellites heading on the left side of the homepage. A table will
pop open
with a week's worth of passes that includes pertinent information like
brightness, altitude, and magnitude of the flare at flare center, the
brightest
possible magnitude for a particular pass. Clicking on the date will
produce a
map showing the flare's path and ground track where the flare will appear
brightest. When that path passes near or over your location, you'll see a ?8
dazzler. If not, you can use the map to drive to the sweet spot and
await the
display.
The transition to the Iridium NEXT generation will be gradual but
certain, so
make the most of the opportunities that remain. If you're a teacher, do your
homework and plan an outing to show a daytime flare to your science class.
Anything that gets people talking more about the sky is a good thing, and I
guarantee those kids will never forget the sight.

John,
My satellite 'battle station' uses a three-element 2m Yagi and a six-element
70 cm Yagi, both based upon the antenna set found in the July/August and
September/October 2006 issues of AMSAT Journal. I've used them for many
QSOs on the FM birds and they should work fine on the transponder birds,
too.
I would imagine that the antennas you've described should work fine. I
presume you will be placing them on an AZ/EL mount? I've read that if you
can only have an azimuth rotator, you can place the antennas at a fixed
elevation of 15 degrees. You'll experience fading if the satellite passes
directly overhead, but that doesn't happen too often.

Dear All of AMSAT India
The delegate of Radio Amateur Society of Thailand under the patronage of
His Majesty the King (RAST) has provided us with AMSAT India contact
information in conjunction with our plans to launch a CUBESAT amateur radio
satellite in the near future. Perhaps, I should begin with a brief
introduction and an outline of our project to launch Thailand's first
amateur radio satellite. RAST is the national non-profit society for
amateur radio enthusiasts in Thailand which qualifies as a charitable
entity pursuant to a Thai Ministry of Finance declaration while the society
is also a member of the International Amateur Radio Union.
RAST has joined three Thai institutes of technology to support the first
Joint Academy Intelligent Satellites for Amateur Radio of Thailand
(JAISAT-1) project which has received funding from the Broadcasting and
Telecommunications Research and Development Fund for the Public Interest
(BTFP), which is under Thailand's regulator, the National Broadcasting and
Telecommunications Commission (NBTC). The three academic institutes are all
in the King Mongkut's Institute of Technology group, being King Mongkut's
University of Technology of North Bangkok (KMUT-NB), King Mongkut's
University of Technology Thonburi (KMUTT) and King Mongkut's Institute of
Technology Ladkrabang (KMITL).
In a meeting on July 22, 2015 the NBTC committee approved state funding for
RAST's JAISAT-1 project over a two-year period: 2016-2017. In my capacity
as the JAISAT-1 project leader in charge of building the satellite along
with a technical team from RAST, I am writing to you with a humble request
for assistance. We currently face the challenge of finding an appropriate
rocket for the launch of the CUBESAT satellite, one that will be within our
limited budget and we are interested in India's Polar Satellite Launch
Vehicle or PSLV rocket.
In addition to our JAISAT-1 satellite there are two other CUBESAT projects
that have received funding in Thailand, including a KNACKSAT satellite to
be built by the King Mongkut Institute of Technology of North Bangkok
(KMUT-NB) and a SPACEBOX satellite to be built by the King Mongkut
University of Technology Thon Buri (KMUTT) as part of a project to "Explore
the World" using remote sensing with these satellites being equipped with
cameras. But RAST 's JAISAT-1 satellite will be for amateur radio
communications for which we are designing and building a linear transponder
ourselves in Thailand and we would like to seek your recommendations to
help us to get in touch with someone who can provide a PSLV rocket to
launch the CUBESAT satellite at a special rate one that we will be able to
afford. We would very much appreciate any assistance, advice or
recommendations that you can make for us to help our project achieve all
its goals.
With deep respect. Sincerely,
Tanan Rangseeprom, HS1JAN
JAISAT-1 Project Leader Manager

Greetings Mac,
Thanks for this!
The AMSAT ftp site isn't updated frequently enough for the deteriorating
orbit and a single precision PLAN13 implementation on the ATmega1280.
As an example here's the CELESTRAK output:
BY70-1
1 41909U 16083C 17029.24424671 .00506735 24288-5 70240-3 0 9991
2 41909 97.5768 109.7306 0160558 244.2616 114.2002 15.85900257 5044
Here's the AMSAT record sampled from the same time.
BY70-1
1 41909U 16083C 17026.84471594 .00329730 24344-5 49404-3 0 9999
2 41909 97.5781 107.0760 0167800 253.3870 105.1424 15.83446051 4663
As expected, atmospheric drag has the largest effect on the semi-major axis,
eccentricity, and argument of perigee. Alas it won't be long now. Still
haven't gotten a confirmed QSO!
Best
Todd
