Is Husky-1 transmitting telemetry every pass? I could hear it yesterday OK
but it was a high elevation pass a few min ago & heard nothing.
Secondly, if someone posts up a good audio recording we should be able to
replay it with our own FOX-1 s/w and decode frames, is that a correct
assumption?
Thanks everyone!

Yes, it is in a mode where it is transmitting telemetry continuously. It
has been very reliable for me (I have a beam that tracks it) that every
pass I've watched, I've seen the downlink. That said, there are a lot of
reasons why you might not get a good decode, chief among them a
somewhat weak signal and FoxTelem very slightly off in frequency, maybe due
to an old set of keps.

Yes, a good audio recording should decode, especially if it is recorded
directly from, say, HDSDR. I don't know about recording it with a
microphone/speaker or even hardwired from a radio. Anyone have any
experience with doing it that way?

Paging KG4AKV...... How did you record the audio from your 706MKIIG? (John
posted a youtube video of him decoding a recording successfully, but not
sure how he recorded it).

I record the audio from the external speaker port on my Icom
IC-706MKIIG into a Sony audio recorder in the wav format. Then I
transfer the file to my computer and play it in Audacity and use a
virtual audio cable to feed it to FoxTelem.

Mike, regarding your question about using a known good recording, you
could probably pipe my YouTube video into FoxTelem and decode it, and
for sure you can use my actual recording:
https://www.dropbox.com/s/sqme37lajuqrrci/2020-02-02_-_1832_UTC_-_HuskySat-1_K
G4AKV_FM05.wav?dl=0
Mine is not a great recording compared to ones that had automatic
frequency control to accommodate Doppler shift, but I did get 49
packets out of it! Make sure you disable "Upload to Server" in
Settings > Decoder Options, before you decode it or else you'll get
credit for my "work" ;-) Also, the recording only has useful audio
after the 6 minute mark.

Note, you can also let FoxTelem open the wav file directly. No need
for a VAC. The main reason I piped it was so I could play it back real
time to make a video.

Warning - TMI (too much info! ...but as an engineer who sees things in
numbers...)
Turns out I went from 200 lbs down to 160 in 4 months as tumor grew and was
finally removed 0.1" larger than a basketball! They still cannot identify
it!
In recovery. Lesson is push Dr's for reports and scheduling. One week
delay between each of 22 Dr procedures adds up over 4 months, and 3
surgeon team over 8 hours. And 8 days in hospital... I cannot imagine the
cost! So glad to have insurance.
No emails please. It is 8th day in hospital and 1st time to to look at
computer and 8 day backlog. Things are looking uup!

Subject: [amsat-bb] amsatLink - a proposed cross-linked satellite
communications network
Message-ID: <1055884481.106118.1580798960686@????.?????.???>
Content-Type: text/plain; charset=UTF-8
I wanted to take a moment of your time to share a project proposal I am
working on, called amsatLink ? an open source nanosatellite constellation
that enables cross-link communication and multipoint scientific measurements
??
amsatLink is a proposed three-phased program to ultimately establish a
constellation of nanosatellites, linked in a peer-to-peer voice
communications network for amateur satellite service.? As a wireless ad hoc
network, future satellites can be added to the network and ground stations,
moving in and out of individual nanosatellite node footprint can easily join
and depart the network.
??
In addition, as a constellation of nanosatellites orbiting the Earth,
AMSATlink allows? for the multipoint collection of space weather
measurements, which contribute a unique and invaluable scientific data set
for scientific and educational analysis.
??
While the idea of cross-link communication between satellites is not new,
amsatLink hopes to continue the progression of NASA?s PhoneSat, EDSN
constellation, and NODES missions.? amsatLink differentiates itself by (1)
expanding the network to include ground-based nodes, (2) demonstrating the
use of voice over internet protocol communications, and (3) organizing nodes
into clusters, where each cluster consists of one nanosatellite node and all
visible ground nodes.
? ?
Phase 1 will focus on designing and building working prototypes of both
nanosatellite and ground nodes as a proof of concept and system
integration.? Testing will include a terrestrial-based simulation and a
high-altitude (60,000 ? 105,000 feet ASL) simulation as a payload aboard
high-altitude HAB launch.
??
In Phase 2, we will build two 1.5u nanosatellite nodes and launch them from
the ISS as a technology demonstrator of a peer-to-peer communications
network.? Due to the ISS-launched orbits being only 400km-415km, we expect a
short mission lifetime of only one to two weeks.
??
Phase 3 will begin with the initial deployment of a three 1.5u nanosatellite
formation at an optimal orbital altitude.? Subsequent launches will add
nodes to the network, greatly expanding the cross-link coverage area.
??
In addition, amsatLink will continue NASA?s design philosophy by strictly
utilizing commercial-off-the-shelf hardware and keeping the design and
mission objectives as simple as possible.? Estimated total hardware cost per
satellite is $5,000. Proposed ground stations will also use commercial off
the shelf equipment with a total estimated cost of less than $150.
??
The amsatLink program is just getting started.? You can follow along by
visiting the GitHub page https://ke4al.github.io/amsatLink/ and GitHub
repository https://github.com/KE4AL/amsatLink.? In addition, I have set up a
Twitter account (https://twitter.com/Amsat_Link) to share day-to-day efforts.

Hello, everyone!
On Feb 12, several CubeSats are scheduled to be deployed from the ISS into
orbit. Among them is the Phoenix CubeSat, which is a 3U CubeSat developed
by Arizona State University to study the effects of Urban Heat Islands
through infrared remote sensing. Following deployment, our operations team
would appreciate as much help as possible with identifying the spacecraft
and verifying that it is operational!
Phoenix is scheduled for a deployment time of *8:30 UTC.*
In addition, I would also like to call special attention to the fact that
two CubeSats being deployed on this date operate on the same frequency.
Both Phoenix and QARMAN share the frequency of *437.35 MHz*, and and
utilize an AX.25 9600 baud protocol with GMSK modulation. Both CubeSats
will also be deployed within 1.5 hours of each other, and will therefore be
close to each other in orbit. If you intend to track the CubeSats on this
upcoming deployment, please be mindful of this situation, and if you have
any doubt about the CubeSat that you are receiving from, please feel free
to get in touch with me with any questions or concerns.
To read more about the Phoenix CubeSat, it's transmitter characteristics,
and how you can decode the signal, please see our website at

Is there a website that I can get a AMSAT graffiti to put on a poster
board????? I will be at a grade school, 7QP and Field Day demonstrating
satellite operations and the hobby.
I was thinking a poster board of 16" by 24" minimum so the file maybe

Hi!
AMSAT will be at the Yuma Hamfest, which is also serving as the 2020
ARRL Southwestern Division Convention, on Friday and Saturday, 14-15
February 2020. The hamfest will be at the Yuma County Fairgrounds,
along 32nd Street, across the street from Yuma International Airport
and Marine Corps Air Station Yuma, south of Interstate 8. More about
the hamfest is available at:
http://www.yumahamfest.org/
WD9EWK will be on the satellites during the hamfest, demonstrating
satellite operating. If you hear WD9EWK on a pass, please call and join
in the demonstration. The hamfest site is in grid DM22, in Arizona's
Yuma County. QSOs made during the hamfest will be uploaded to Logbook
of the World, and QSL cards are available on request (please e-mail me
directly with the QSO details).
I will tweet updates from the hamfest using my @?????? Twitter account.
If you do not use Twitter, you can see the tweets in a web browser at:
http://twitter.com/WD9EWK
In addition to the AMSAT presence in Yuma, AMSAT member Dave
Bartholomew AD7DB will give a presentation "Getting Started on FM
