Hi Mike,
If you're using AF in Foxtelem (meaning, not IQ...), I suggest you try to
get the carrier frequency around 1400-1500 at AOS. It shows up in very
light grey text, between the two "wave forms"...if you look carefully,
you'll see it. These details are only as good as the TLE data! So
update frequently, especially now right after launch (maybe every couple of
days?).
Currently, here is what I use in SatPC32--but it varies by radio to get the
1400-1500 Hz carrier!
For my TS-2000x:
HuskySat-1,435799.8,145950.0,USB,LSB,REV,0,0,Telem Beacon
For my IC-9700:
HuskySat-1,435798.4,145950.0,USB,LSB,REV,0,0,Telem Beacon
Hope that helps with both specifics as well as strategy!
73,
Mark N8MH

AMSAT NEWS SERVICE SPECIAL BULLETIN
ANS-036
The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT North America, The Radio Amateur Satellite
Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio
satellites.
The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.
Please send any amateur satellite news or reports to:
ans-editor at amsat.org.
You can sign up for free e-mail delivery of the AMSAT News Service
Bulletins via the ANS List; to join this list see:

From AMSAT HQ KENSINGTON, MD.
DATE February 5, 2020
To All RADIO AMATEURS
BID: $ANS-036.01
Clayton Coleman, W5PFG, Elected AMSAT President
At a special meeting held via teleconference, the AMSAT Board of
Directors elected Clayton Coleman, W5PFG, President. Coleman previous-
ly served as a member of the Board of Directors from 2017-2019 and
also served as AMSAT's Secretary during this time. He has also volun-
teered in several other capacities for AMSAT, including chairing the
2016 AMSAT Space Symposium held aboard the cruise ship Carnival
Liberty.
Coleman?s first introduction to amateur radio in space was with SAREX
and Mir. An interest in setting up an AX.25 BBS and nodes led to him
trying out the Mir Personal Message System (PMS) and digipeater to
make contacts in the early 1990s. It wasn?t until a visit from a
friend in 2011 that Coleman was bitten by the OSCAR bug and began his
AMSAT journey chasing operating awards.
Having held other leadership roles in his community, nonprofits, and
critical infrastructure, Coleman?s desire is working with constituents
to improve organizational processes and align them with strategic
goals. Professionally, Coleman works in the industrial process con-
trol sector as both a consultant and business development manager. He
resides in the North Texas area with his spouse and two children.
AMSAT members will have the opportunity to meet Coleman at the Orlando
HamCation on Saturday, February 8th. He will hold a meet and greet at
the AMSAT booth from 9:30am-10:30am and 2:00pm-3:00pm. He will also
make remarks at the AMSAT Forum, which will be held at 12:30pm Satur-
day in Room CS III at the Lakeside Pavilion.
[ANS thanks the AMSAT Board of Directors and AMSAT President Clayton
Coleman, W5PFG for the above information]
In addition to regular membership, AMSAT offers membership in the
President's Club. Members of the President's Club, as sustaining
donors to AMSAT Project Funds, will be eligible to receive addi-
tional benefits. Application forms are available from the AMSAT
Office.

Perhaps your update process went awry? I just double checked and HuskySat-1
is at the very end of nasabare.txt lines 595-597
Check other entires in nasabare.txt. The epoch field for most spacecraft
should be within a day of 20030.00000000
e.g:
AO-07

and if you need it
HuskySat-1

I attempted to use AO-92 in L/v today at ~1900 UT. I couldn't hear myself
but I could hear the announcer. Perhaps I have an issue with my 23cm setup.

What are all all the computer controlled stations using for doppler
adjust interval? I had previously tried 100ms, and was getting about 45
frames per decent pass. I just had a 50deg pass and increased the
interval to 500ms, and got almost 70 frames. I wonder if there is a sweet
spot?

Kevin bring up an interesting point about the validity of HuskySat-1
elements and their "freshness". Usually element sets are good for a week
or more, at least for ham purposes where we have fairly wide beam widths.
The exception is the ISS, the only spacecraft we have in nasabare.txt that
maneuvers, and we keep its element sets "fresh" by applying updates from
Johnson Spaceflight Center several times per day. Husky-Sat 1 will be
testing a thruster early in its mission, and endeavors to demonstrate a
delta-V of 100m/sec or more. This could cause the accuracy of element sets
to degrade more quickly than usual. Do we know if the University of
Washington people are doing any orbit estimation/determination?
Also, I updated nasabare.txt with the fresher elements Kevin posted.
Given that he has more than 2500 packets received, I'll use what he is using.

Hi Roy!
I use Orbitron on Windows and the best I can do there is one refresh per
second.
I've not tried FoxTelem w/ HuskySat-1 on linux, but the nice thing about
GPredict is that you can get smoother doppler adjustments by using a
shorter update interval. I use 1/2 second for doppler tracking w/ GPredict
most of the time.
I guess use what is producing the best result for you, but I've never
noticed that the update interval was a critical factor with various
telemetry decoding efforts. Much more impactful with HuskySat-1's BPSK
signal is to keep that audio output centered around the 1500 Hz mark.
Fine-tuning your signal during a pass to keep it as close to center as
possible in your 3k passband will produce best results, I think.
