Successful Launch of BY70-2 With FM-to-Codec2 Transponder

Wei Mingchaun, BG2BHC, reports on Twitter that BY70-2 was launched on
July 3 at 03:10z from Taiyuan Satellite Launch Center on a CZ-4B launch
vehicle. BY70-2 will serve as a replacement for BY70-1, a 2U CubeSat
which launched on December 26, 2016. Due to a booster failure, BY70-1
was placed in an elliptical orbit with a low perigee and the satel-
lite's orbit decayed in February 2017.

Unlike BY70-1, which carried an FM transponder, BY70-2 carries an
FM-to-Codec2 transponder similar to the ones on board LO-90 and
Taurus-1. More information about working this type of transponder can
be found in an article entitled "Digital Voice on Amateur Satellites:
Experiences with LilacSat-OSCAR 90" by Paul Stoetzer, N8HM, in the
January/February 2019 issue of The AMSAT Journal. The article can also
be found on the AMSAT website at https://tinyurl.com/ANS-166-BY70-2.

BY70-2 is in a sun-synchronous orbit with an altitude of approximately
500 km. As a replacement, the satellite is sharing BY70-1's IARU coord-
ination and ITU API notification. The uplink frequency is 145.920 MHz
and the downlink frequency is 436.200 MHz.

AMSAT Responds to Allegations of Unauthorized Legal Expenses

The Radio Amateur Satellite Corporation (AMSAT) has been made aware of
public comments alleging financial mismanagement in the form of
“unauthorized” legal expenditures. AMSAT takes these allegations very
seriously and in full disclosure, has investigated these claims for
many months.

AMSAT’s corporate records give a full accounting of all expenditures
and are provided to its Directors upon request, in compliance with our
governing documents and law of the District of Columbia (D.C.) Our
office remains closed due to COVID-19, where those documents reside.
Furthermore, AMSAT complies with IRS rules for 501(c)(3) disclosure of
public financial documents, such as the Form 990 available on the
AMSAT website. Financial review and accounting services from a third-
party firm of Certified Public Accountants are utilized by the
corporation to ensure governance to best practice and law.

The Corporation vehemently denies false statements alleging
“unauthorized” expenditures.

On behalf of AMSAT,

Clayton Coleman, W5PFG
President

Virginia Air and Space Center Discontinues KE4ZXW Demo Station

The Virginia Air and Space Center in Hampton,Virginia has ended its
twenty-five year relationship with the KE4ZXW Amateur Radio Demonstra-
tion Station. Robert Griesmer, Executive Director and CEO of the Vir-
ginia Air and Space Center has directed that the KE4ZXW Amateur Radio
Demonstration Station located at the Virginia Air and Space Center
(VASC) be disassembled and removed from the Center by June 30.

In his June 5,2020, update Mr. Griesmer advised the following to the
KE4ZXW group : “I am writing to you to inform you that, after careful
consideration, we have decided to discontinue the Ham Radio Station Ex-
hibit effective July 1st upon the re-opening of the Center.” Randy
Grigg, WB4KZI, president of the Amateur Radio group, thanked the volun-
teers who have supported and operated the station for the last 25 years.

The station has spent the last quarter of a century demonstrating  the
use of Amateur Radio, its applications as a STEM Activity, communica-
tions skills  and communications through amateur satellites to school
groups. The station also made contacts to the International Space Sta-
tion.

The KE4ZXW Amateur Radio station's equipment has found a new home with
K4KDJ, the Virginia Tech Amateur Radio Association in Blacksburg, Va.

CAS-6 Becomes TO-108, Confusion Ensues

At the request of CAMSAT and the CAS-6 team, Drew Glasbrenner, KO4MA,
AMSAT VP Operations & OSCAR Number Administrator announced last week
that CAS-6 (TQ-1) would receive the official designation of TQ-OSCAR
108 (TO-108).

Since that designation, TO-108 was added to the AMSAT Live OSCAR Satel-
lite Status Page at https://www.amsat.org/status/  However, an entry
for CAS-6 also remains on that page. Further, AMSAT TLE distributions
continue to list the satellite as CAS-6 (NORAD Cat ID 44881).

Operators should be aware that the designations CAS-6 and TO-108 both
refer to the same satellite, and should be on the lookout for changes
in the naming on websites and in TLE distribution sets. It many take a
week or two before consistent naming filters through all systems.

Frequencies for the intended radio amatuer mission are:
• CW Telemetry Beacon: 145.910 MHz
• AX.25 4.8kbps GMSK Telemetry: 145.890 MHz
• U/V Linear Transponder Downlink: 145.925 MHz, 20 kHz bandwidth
• U/V Linear Transponder Uplink: 435.280 MHz, Inverted

Operator reports indicate that the transponder is active only for brief
intervals of about 2 seconds, spaced approximately 5 seconds apart. With
patience, and quick transmissions, QSOs have been completed.

San Diego Microwave Group Discusses ARISS Possibilities

Participants in the San Diego Microwave Group's (SDMG) 29 June 2020
Zoom meetup discussed the possibility of the AREx broadband digital
microwave design being potentially deployed on the International Space
Station (ISS).

Since the project has focused heavily on high earth orbit, geostation-
ary orbit, and the lunar opportunity with Gateway, the challenges of
low earth orbit (ISS) now need to be addressed. This will be an ongoing
process. Here's what participants recommended at SDMG:

Since there are LEO constellations up to and including Ka band, the
tracking and doppler have been done. It's just a question of learning
the requirements, design patterns, limitations, and techniques.

Since the project already incorporates the near-space communications
recommendations from Consultative Committee for Space Data Systems
(CCSDS), little has to be done in that regard.

HamTV on ISS is at 2.4 GHz, which while lower than the projected 5 GHz
and 10 GHz, has all the other aspects of broadband digital. There is
plenty to be learned from those experiments, and meetings are being
set up to begin to collaborate with the principals of HamTV on deeply
appreciated advice & next steps.

There was strong advice to eliminate antenna pointing. Use of an anten-
na system in space and on the ground that does not require tracking
would dramatically increase adoption. With Adaptive Coding and Modula-
tion, all sorts of systems can be accommodated. However, a ground sta-
tion that does track can use a directional antenna with a lot more
gain, and get a much higher bitrate, while a station with a 120 degree
field of view would get a lower bitrate, but would not have to track
at LEO. This needs thorough link budgeting.

There are several link budgets in Jupyter Notebook in progress at
https://github.com/phase4space/payload-dmt  Others interested in help-
ing here are most welcome.

Testing for human rated spacecraft incurs a substantial increase in
engineering, paperwork, and time requirements. Putting the equipment
outside instead of inside does not eliminate the testing requirements.
This is going to require advice/direction from ARISS.

Space heritage of this type, where equipment is an external payload
only requiring power, makes hosted payload options easier to negotiate.
There are 5-6 GEO missions going up in the next 3 years that could be
targeted.

Doppler is a factor here, and SDMG participants received strong recom-
mendations about talking with particular ARISS team members with exper-
ience. SDMG will be learning from and incorporating their advice in the
very near future.

Directors, for the above report]

ARISS NEWS

Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.

Scheduled contacts and events:
   Don Bosco Haacht Technisch en Beroepsonderwijs, Haacht, Belgium,
   Multi-point telebridge via AB1OC. (A multi-point telebridge contact
   means that each student will be on the telebridge from their own
   home.) The ISS callsign is presently scheduled to be NA1SS, and the
   scheduled astronaut is Chris Cassidy, KF5KDR. The contact is go for
   Friday, July 10 at 10:49:51 UTC (27 degrees maximum elevation).

ARISS is very aware of the impact that COVID-19 is having on schools
and the public in general. As such, we may have last minute cancella-
tions or postponements of school contacts.

Satellite Shorts From All Over

+ There has been further work on trying FT8 for EME, this time on 1296.
  It turns out that, contrary to the original news item, the Doppler
  spread on the lower bands is not an issue, since the energy distribu-
  tion of the EME signal is mainly concentrated in a much narrower
  spectrum than the maximum total Doppler spread. This means that it
  can work probably with little degradation on bands up to and includ-
  ing 1296, under most circumstances. For a writeup of this work please
