I dont think that will work. There has to be a tone, say 400 Hz that is
then AM modulated at 3.25 Hz. The 400 Hz or so lets it get through your
transmitter audio circuits, and then the 31.25 Hz AM modulation of that
tone is what looks like PSK31 carrier.
Both PSAT and PSAT2 both have an audio PSK31 telemetry down around 300 Hz
(I need to look them up) so we need to avoid those areas so as not to
interfere with telemetry. And not go above say 500 to avoid being in the
area where the SSTV tones are.

PSAT2 has plenty of power all the time to support the PSK31 and SSTV HF/UHF
transponder because it lost its VHF xcvr. So this mode will be around a
long time with plenty of power. Same goes for PSAT since most of the time
its VHF xponder is off.
And I looked up the PSAT PSK31 telemetry is at 312 Hz and the PSAT2
telemetry is a 374 Hz, so any pilot tone between about 400 and 800 Hz
should be fine and not interfere with the SSTV.

AMSAT Receives PPP Funds During COVID-19 Pandemic
On March 31, 2020, AMSAT's Board of Directors authorized the
organization's leadership team to pursue relief afforded by the
Coronavirus Aid, Relief, and Economic Security Act (CARES Act).
Pursuit of this relief was in accordance with the Directors'
fiduciary duty to pursue all funding sources available to sustain
AMSAT's operations.
AMSAT has received funds under the CARES Act's Paycheck Protection
Program (PPP). Participation in this program gives us certainty that
AMSAT will be able to continue uninterrupted service to our members
during these uncertain economic times. It helps AMSAT offset cash
flow losses due to the pandemic and avoid dipping into our reserves.
Using reserves at this time would incur substantial realized losses
due to fluctuating investment market conditions. Receiving the PPP
funds also allows AMSAT to continue paying Martha, AMSAT's Office
Manager of over 40 years, even though our physical office remains
closed.
Although AMSAT remains in a healthy financial position with a strong
balance of cash and reserves, the current economic situation and loss
of events like Hamvention and Ham-Com will likely continue to
negatively impact donations and membership renewals.
AMSAT's senior leadership team continues to pursue avenues to reduce
operational costs such as the recent successful roll out of the Wild
Apricot membership management portal.

HuskySat-1 Transponder is Open
Drew Glasbrenner, KO4MA, AMSAT VP - Operations reports that after a
week of testing, the transponder on HuskySat-1 is enabled and open
for use and testing. HuskySat-1 carries a V/u inverting transponder
with a 145.910 to 145.940 uplink, 435.810 to 435.840 downlink. The
telemetry beacon runs 1200 baud BPSK at 435.800
It's fairly sensitive, and 5-10 watts is plenty most of the time.
There are some fades due to satellite orientation and some passes
are definitely better than others. The operations and engineering
teams are also watching a few anomalies. For those with spectrum
scopes, lease keep an eye on the beacon during transponder
operations. Strong signals may impact the beacon strength. Reports
and observations are welcome to the amsat-bb mailing list.
HuskySat-1 is the Husky Satellite Lab at University of Washington's
first cubesat, and the first mission with AMSAT's linear transponder
module (LTM-1), a V/u transponder and integrated telemetry beacon and
command receiver. UW recently completed their Part 5 operations and
have graciously let AMSAT's Part 97 transponder operations commence.
This transponder module is available for use in educational cubesat
missions willing to enable the transponder for worldwide use. Contact
Drew Glasbrenner or Jerry Buxton, VP Engineering Jerry Buxton for
additional details.
Congratulations to Husky Satellite Lab, and to the entire AMSAT
Engineering team for keeping amateur radio in space. Thanks to Dr.
Mark Hammond, N8MH for commissioning and operations support.

HuskySat-1 Designated OSCAR 107 (HO-107)
On November 2, 2019, the HuskySat-1 cubesat launched on the Cygnus
NG-12 mission from Wallops Island, Virginia, USA. The satellite was
constructed by the Husky Satellite Lab at the University of
Washington, and utilizes an AMSAT-constructed radio system for
primary communications. Deployed from the Cygnus vehicle on
January 31, 2020 after departing the ISS, HuskySat-1 began a 3-month
educational mission. Upon completion of that mission, the satellite
began operation of a V/u linear transponder in Amateur Radio Service.
At the request of the Husky Satellite Lab and AMSAT teams, AMSAT
here-by designates HuskySat-1 as HuskySat-OSCAR 107 (HO-107). We
congratulate the Husky Satellite Lab, thank them for their
contribution to the Amateur Radio satellite community, and wish them
continued success on this and future projects.

fulfill the second part of our mission statement to continue active
participation in human space missions.
The LTM represents the primary work AMSAT is doing to "support a
stream of LEO satellites developed in cooperation with the
educational community and other amateur satellite groups". Five
Fox-1 satellites have been completed. HO-107 is just the first of
many more missions that will help us to Keep Amateur Radio in

ARISS Continues Test of MultiPoint Telebridge Contact via
Amateur Radio
ARISS completed the second test of the new-style radio contact
called Multi point Telebridge Contact via Amateur Radio. The concept
was developed for distance learning when schools closed worldwide due
to COVID-19. The virus eliminated all opportunities for ARISS radio
contacts at education organizations.
The radio contact was completed on May 15 with ISS Commander
Chris Cassidy, KF5KDR. A new ARISS telebridge ground station was
operated by John Sygo, ZS6JON located near Johannesburg,South
Africa. The telebridge linked to the astronaut and each youth tied
in from home via their telephones. Each student took a turn asking
their question of the astronaut. Their families, faculty and the
public could also listen from home.
The youth taking part in ARISS's second test belong to the Airdrie
Space Science Club in Airdrie, AB, Canada. Prior to COVID, the
students had participated in space and radio communications lessons
such as balloon launches with ham radio payloads and building model
rockets to launch. Brian Jackson, VE6JBJ, one of the five club
leaders related, "During this pandemic, our opportunities to develop
kids' interest in space has been interrupted. This ARISS contact gets
them looking back up, towards the sky, and imagining themselves as an
astronaut one day."

AMSAT-EA Receives IARU Coordination for Two Satellites
AMSAT-EA recently received frequency coordination from the IARU for
two pocketcube satellites expected to launch in 2020.
Hades is a 1.5 p pocketcube satellite offering radio amateurs a
linear transponder for SSB/FM/CW and digital modes. It will also
test the platform for future amateur satellites. A downlink on
436.888 MHz and an uplink on 145.925 MHz have been coordinated.
A regenerative transponder for FM/FSK/ASK and 0.05kbps-125kbps
ASK/FSK/PSK telemetry, store&forward and data transmission from
ground stations is also planned. A camera is expected to fly as an
experimental payload.
EASAT-2 satellite is Hades virtual twin with a downlink on
436.666 MHz and an uplink on 145.875 MHz. Both satellites will be
launched into a 400/500 km polar orbit together with Sanosat-1 and
others in a Alba Orbital cluster 3 launch.

AO-7 Delivers Stunning Contact
On Sunday, May 4, 2020, AO-7, a forty year old satellite, produced a
stunning contact. At 17:20 UTC a contact was completed between
Diego Fiel, LW2DAF in Buenos Aires (GF05rk) and Tom Ambrose, ZS1TA in
Cape Town (JF95fx). The contact scanned a distance of 4329 miles
(6927 km) across the South Atlantic with both stations aiming at
only 2 to 3 degrees on the horizon.
Both stations had been watching the orbit predictions for several
weeks and the suitable opportunities only occurred occasionally with
both stations seeing the AO-7 satellite at the same time. Electrical
noise particularly in Cape Town hampered the efforts with only small
snatches being heard from time to time. That morning, however, the
noise levels were low and a perfect contact was possible with full
call signs and reports being exchanged.

I'd appreciate a pointer to where to get an SSB preamp repaired. Failed

or repair.

About ARISS:
?
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS).? In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.
