Hi Alex
Can you describe a bit more on how you do your calibration?
It works for me, but I had to do it for each satellite and then hit
"Change/Store Data File", the hit the button under Store "Uplink
Calibration".
It mostly works but I might still have to touch it up from time to time.

Yes, but I've also had experience with expensive transceivers and
transverters desensing on FM and SSB when I transmit.
It's a common issue, especially if the uplink is on VHF and the
downlink is on UHF (3rd harmonic).

Scott actually used an eclipse timing and corresponding loss of carrier to
prove to himself that he was detecting that LES-5.

I think you may be confusing the satellites mentioned in the article.
The article claims that Transit 5B-5 was nuclear powered, which
matches the NASA record. But Scott claims to have identified LES-5 by
eclipse times. LES-5 is a completely different bird than Transit 5B-5.
Scott found Transit 5B-5 a couple years ago, and he found LES-5 just
last month.

The command team has had a few requests for camera mode on AO-92 over the
last few weeks, and it's been a while, so let's take some pictures next
week.
Next Tuesday morning, April 28th, we'll attempt to command the camera on at
approximately 1440Z and 1612Z. We'll also try the 1750Z pass. If we can't
command on the 1750Z pass, we'll find a suitable pass later in the week for
the west coast.
Take a look at
https://www.amsat.org/foxtelem-software-for-windows-mac-linux/ for a guide
on how to set up FoxTelem, and https://www.amsat.org/tlm/showImages.php?id=4
for near-live images as we go. Remember, the more stations submitting
telemetry during the event, the better the chance of complete images!

The clock is important to be as accurate as possible. Also make sure that
you are using as accurate a latitude and longitude setting in Observer
setup. Even just using two decimal places after the Lat/Lon value may not
be adequate especially on high passes even if the clock is accurate. These
two settings will make all the difference.

Have you checked your system clock? Try https://time.is which is very
accurate. Some computer clocks can drift badly, and this can cause the need
for constant tweaking, even with very stable satellites.

Long-Lost U.S. Military Satellite Found By Amateur Radio Operator
Scott Tilley, VE7TIL, has made the news once again for tracking down
yet another "zombie" satellite. Scott was the subject of a report
broadcast on National Public Radio on Friday, April 24.
This time, he managed to identify signals from LES-5, an experimental
military UHF communications satellite built by the Massachusetts Insti-
tute of Technology's Lincoln Laboratory and launched in 1967. Even
though the satellite was supposed to shut down in 1972, it's still go-
ing. As long as the solar panels are in the sun, the satellite's radio
continues to operate.
In 2018, Tilly found a signal from a NASA probe called IMAGE that the
space agency had lost track of in 2005. With Tilley's help, NASA was
able to reestablish contact. He has rediscovered several other long-
forgotten birds, including Transit 5B-5, a nuclear-powered U.S. Navy
navigation satellite launched in 1965.
Scott announced his findings on LES-5 through his Twitter account,
@???????????? on March 24. The full NPR story may be found at:

Let's Take Some Pictures
The command team has had a few requests for camera mode on AO-92 over
the last few weeks, and it?s been a while, so let?s take some pictures
next week.
Next Tuesday morning, April 28th, we?ll attempt to command the camera
on at approximately 1440Z and 1612Z. We?ll also try the 1750Z pass.
If we can?t command on the 1750Z pass, we?ll find a suitable pass
later in the week for the west coast.
Take a look at

for a guide on how to set up FoxTelem, and
https://www.amsat.org/tlm/showImages.php?id=4 for near-live images
as we go. Remember, the more stations submitting telemetry during
the event, the better the chance of complete images!

Changes to AMSAT-NA TLE Distribution
Last week's AMSAT News Service Weekly Bulletin (ANS-110.01) contained
a news item entitled "Receiving SMOG-P and ATL-1 Nano Satellites With
an RTL-SDR" from Zoltan Doczi, HA7DCD.
Please note that on December 19, 2019 AMSAT designated SMOG-P as
Magyar-OSCAR 105 (MO-105) and ATL-1 as Magyar-OSCAR 106 (MO-106).
In the AMSAT-NA TLE Distribution, the TLEs for these two Hungarian
satellites are shown as follows:
MO-105 is NORAD Cat ID 44832 (SMOG-P)
MO-106 is NORAD Cat ID 44830 (ATL-1)

The W4AMI Award and How to Obtain One
Just a little history, Robert W. Barbee Jr., W4AMI, was a very prolific
operator and in his honor this certificate was created and the first
certificate was issued to him on June 27, 1994. He has since become an
SK and his local club has taken over his call sign. The award was
originally the W4AMI Satellite Operator Achievement Award. The local
club asked me not to use their call sign for the award. I changed the
award to The Robert W. Barbee, Jr. W4AMI Satellite Operator Achievement
Award. And here we are today, finally having issued over 100
certificates and over 30 of the 5,000 certificates.
This award is for making 1,000 contacts with any station any time. You
can say hello to your friend on every satellite on every pass every day
and count those contacts. That being said, any contact you log counts.
The award has endorsements for making 1,000 more contacts up to 4,000.
Another 1,000 contacts will earn a special W4AMI 5,000 certificate.
To submit for the award, please email me an extract from your log either
in Microsoft Excel XLS(X) format or ADI(F) format. Either will work just
fine. Then wait for me to get back to you notifying you to go online and
make your payment. I need nothing from LoTW, confirmed contacts are not
an issue, this award is for simply making a contact.

ARISS News
ARISS lets students worldwide experience the excitement of talking
directly with crew members of the International Space Station, inspir-
ing them to pursue interests in careers in science, technology,
engineering and math, and engaging them with radio science technology
through amateur radio.
Northern Virginia Schools Group, Woodbridge VA, Multi-point telebridge
contact via AB1OC is scheduled for Thursday, April 30. The ISS call-
sign is presently scheduled to be NA1SS, and the scheduled astronaut
is Chris Cassidy, KF5KDR. The contact is go for 13:35:00 UTC at a max-
imum elevation of 62 degrees. Stations in the eastern U.S. should be
able to listen in on this contact on 145.80 MHz FM. A multi-point tele-
bridge contact means that each student will be on the telebridge from
their own home.
The ARISS team continues to test and firm up a plan to transform ARISS
contacts and how ARISS interacts with youth and education institutions.
ARISS will provide distance learning with every student and staff mem-
ber in their own homes (even quarantined).

+ Happy 30th anniversary, Hubble! The Hubble Space Telescope was laun-
ched into LEO on April 24th, 1990 aboard Space Shuttle Discovery
STS-31 launch video). Featuring a 2.4 m mirror and optics that are
smooth to 10 nanometers (but were in the wrong shape until corrected
by the first of five servicing missions in 1993), Hubble takes images
of the Universe with never-before-seen quality. The telescope may
work into the 2040s, hopefully being joined by its more-advanced sib-
ling, the JWST, next year. Take a moment to browse some of Hubble?s

+ SpaceX launched 60 more spacecraft Wednesday to join the Starlink
fleet. The successful launch Wednesday marked the 84th flight of a
Falcon 9 rocket since June 2010. That makes SpaceX?s Falcon 9 the
most-flown orbital-class U.S. launcher currently in operation, ex-
ceeding the 83 missions performed by the Atlas 5 rocket built by
rival United Launch Alliance. With Wednesday?s launch, SpaceX has
delivered 422 Starlink satellites to space. The company is seeking
regulatory approval to fly 4,400 of the satellites in the project's
first phase. SpaceX?s next Starlink launch after Wednesday could
happen as soon as early May on another Falcon 9 rocket mission. That
will be followed by SpaceX?s first launch with astronauts on-board ?
scheduled for May 27 ? to begin a test flight of the company?s Crew
Dragon spaceship to the International Space Station.

ning lances down, sprites leap up. They can reach all the way to the
edge of space 90 km or more above Earth?s surface.
