AMSAT Mail Alias Service to End August 31, 2024
A long-standing member service, the AMSAT Mail Alias Service is scheduled
to end on August 31, 2024. A mail alias on AMSAT.ORG permitted people to
send an email to members without knowing their actual internet email
address. They just needed to know their amateur radio callsign.
Unfortunately, the unchecked rise in domain name hacking and email account
high-jacking has made it impossible to sustain this service at a
cost-effective level. The number of callsign ＠ amsat.org email accounts that
had been hijacked and converted to zombie spam accounts over the years had
led many internet service providers and gateway centers to ban all @
amsat.org email addresses, including those business accounts of AMSAT
officers and officials. The tireless efforts of AMSAT’s all volunteer IT
staff has worked for years to repair much of the damage, but AMSAT still
get complaints from members who are not getting their personal emails, ANS
bulletins or AMSAT-BB posts because of persistent delivery problems.
It has come to the point where the AMSAT volunteer IT staff can no longer
keep up with the maintenance requirements to keep the alias mail list clean
and to work with email gateways to remove blocks. And, after considerable
investigation into alternative paid email services, AMSAT leadership
decided that the money required to keep an email alias system alive would
be better spent on building and flying satellites for its members.
Persons using the Mail Alias Service should begin to migrate to different
email accounts so they do not lose receipt of personal emails, AMSAT News
Service Weekly Bulletins, AMSAT-BB posts, or official messages from AMSAT
itself. Members are especially asked to make sure they are NOT using a
callsign ＠ amsat.org as their registered email address in the AMSAT
membership portal. Members can easily change their registered member email
address by logging into the portal and updating their profile.

Tevel Satellites Nearing Re-Entry
The Tevel series of satellites is approaching re-entry, with Tevel-5
already re-entering on July 18th.
The Tevel mission consists of 8 satellites developed by the Herzliya
Science Center in Israel, each carrying an FM transponder. The satellites
were built by 8 schools in different parts of Israel and launched in
January 2022 on the SpaceX Falcon 9 Transporter-3 mission.
A number of other satellites with amateur radio payloads are also
re-entering shortly. A list of satellites approaching re-entry can be found
at http://lu7aa.org/decay.asp

AMSAT-OSCAR 7 in Continuous Sunlight
AMSAT-OSCAR 7, soon to celebrate its 50th birthday on November 15, 2024, is
now in a period of continuous sunlight through May 22, 2027.
While in continuous sunlight, the satellite's internal timer is expected to
switch between the two transponders - Mode A (29 MHz downlink and 145 MHz
uplink) and Mode B (145 MHz downlink and 29 MHz uplink) every 24 hours.
Post reports and check current status on the AMSAT Live OSCAR Satellite
Status Page <https://www.amsat.org/status/>. After a few days in continuous
sunlight, it should be possible to determine the actual or approximate time
the satellite switches.

Changes to AMSAT TLE Distribution for July 19, 2024
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
The following satellites have been removed from this week's AMSAT TLE
distribution:
MESAT1 remains on this distribution. No signals have been detected from any
other amateur spacecraft launched as part of NASA's ELaNa 43 mission.
ELaNa 43 OBJECT A NORAD Cat ID 60203 No amateur signal detected
ELaNa 43 OBJECT B NORAD Cat ID 60204 No amateur signal detected
ELaNa 43 OBJECT C NORAD Cat ID 60205 No amateur signal detected
ELaNa 43 OBJECT D NORAD Cat ID 60206 No amateur signal detected
ELaNa 43 OBJECT E NORAD Cat ID 60207 No amateur signal detected
ELaNa 43 OBJECT F NORAD Cat ID 60208 No amateur signal detected
ELaNa 43 OBJECT H NORAD Cat ID 60210 No amateur signal detected
Zhou Enlai NORAD Cat ID 43156 Decayed from orbit on or about 17 July 2024
TEVEL-5 NORAD Cat ID 50998 Decayed from orbit on or about 18 July 2024
The following satellites have been added to this week's AMSAT TLE
distribution:
GRBBeta NORAD Cat ID 60236 IARU coordinated downlinks on 145.935 MHz,
436.785 MHz and 2405.000 MHz
ROBUSTA-3A NORAD Cat ID 60241 IARU coordinated 9k6 GMSK with AX.25 downlink
on 436.750 MHz
Thanks to Nico PA0DLO for identifying the two new spacecraft.

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.
*Aznakaevsky district schools of the Republic of Tatarstan, Tatarstan
Russia, direct via TBD*
The ISS callsign is presently scheduled to be RSØISS
The scheduled crewmember is Aleksandr Grebyonkin RZ3DSE
The ARISS mentor is RV3DR
Contact is go for Sat 2024-07-27 13:45 UTC
*Arizona Science Center, Phoenix, AZ, telebridge via AB1OC*
The ISS callsign is presently scheduled to be NA1SS
The scheduled crewmember is Matthew Dominick KCØTOR
The ARISS mentor is K4RGK
Contact is go: Sat 2024-07-27 18:24:08 UTC 41 deg
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.
The crossband repeater continues to be active (145.990 MHz up {PL 67} &
437.800 MHz down), If any crewmember is so inclined, all they have to do
is pick up the microphone, raise the volume up, and talk on the crossband
repeater. So give a listen, you just never know.
Note, all times are approximate. It is recommended that you do your own
orbital prediction or start listening about 10 minutes before the listed
time.
The latest information on the operation mode can be found at
https://www.ariss.org/current-status-of-iss-stations.html

Upcoming Satellite Operations
A growing number of satellite rovers are currently engaged in sharing their
grid square activations on https://hams.at. By visiting the website, you
gain easy access to comprehensive information about the operators
responsible for activating specific grid squares. Additionally, you have
the ability to assess the match score between yourself and a particular
rover for a given pass, while also being able to identify the upcoming
satellite passes that are accessible from your location.
*N8MR* will be in *EN57*, with roves to EN67 from Aug 2 thru Aug 10. Icom
9700, Arrow and Alaskan (IO-117) antennas. Listening for Europe on linear
eastern passes, at least two of these on CW. Can operate CW for NA ops, if
anyone wants it. I can rove to EN56, only if needed. Posting passes to
http://hams.at <https://t.co/VDIY566ji4> a day in advance. All QSOs to LoTW
as N8MR.

AMSAT Ambassador Activities
AMSAT Ambassadors provide presentations, demonstrate communicating through
amateur satellites, and host information tables at club meetings, hamfests,
conventions, maker faires, and other events.
AMSAT Ambassador Clint Bradford, K6LCS, says,
"Think a 75-minute presentation on "working the easy satellites" would be
appropriate for your club or event? Let me know by emailing me at
k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!"
Clint has NEVER given the exact same show twice: EACH of the 150+
presentations so far has been customized/tailored to their audiences.
