XW-2A Satellite Decays

The popular linear transponder satellite XW-2A has decayed from orbit. Launched on September 19, 2015 on the maiden flight of the CZ-6 rocket from Taiyuan Satellite Launch Center along with several other amateur radio satellites, including XW-2B, XW-2C, XW-2D, and LilacSat-2, XW-2A was a 25 kg microsat. Two other amateur radio satellites, XW-2E and XW-2F, rode piggyback on XW-2A. After launch, XW-2E and XW-2F deployed and XW-2A performed an orbit lowering manuever.

The record distance achieved on XW-2A was a transatlantic QSO between EA4NF in Spain and VE1CWJ in Nova Scotia in August 2022 - a distance of 4,751 km.

Telemetry of the MSC "ORBICRAFT-ZORKIY" -

Conditions: within 6 days, the satellite will broadcast 6 (six) different images in Robot 72 mode. To receive a diploma, at least 3 (three) of any images must be received and decoded. Each image must be received at least 70% and have an acceptable quality, the logo and call sign of the satellite must be distinguishable.

For image decoding, it is recommended to use RX-SSTV or Robot36 software. Received images must be in their original state and resolution.

Registration of an application for a diploma
An application for a diploma is sent to e-mail. mail and should contain:

Call sign (if available, if not, indicate “no call sign”);
Date and time of receipt (UTC) of each image;
City and country of reception;
Return address for sending a paper version of the diploma (or a note that the diploma can be sent electronically)
Type of hardware and software used;
Accepted images;
Applications will be accepted during the duration of the program (May 07-12, 2023), as well as a day after the end of the broadcast - until May 14, 2023 00:00 UTC.

Please note that submitting an application means your consent to the processing of personal data specified in it.

Diplomas will be sent within 30 days after the deadline for applications, delivery to recipients will depend on the speed of postal services :).

PS There will be special prizes for those who accept all 6 images in good quality ;).

We wish you all good luck!

73! Team Sputniks!

Changes to AMSAT-NA TLE Distribution for March 31, 2023

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

SSS-2B NORAD Cat ID 56184 (uncoordinated frequency: 435.8000 MHz). Thanks to Nico Janssen, PA0DLO for the identification of the above satellite.

The following satellite has decayed from orbit and has been removed from this week's AMSAT-NA TLE distribution:

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.

Quick list of scheduled contacts and events:

Council Rock High School South, Holland, PA, direct via KC3JND (***)
The ISS callsign is presently scheduled to be NA1SS
The downlink frequency is presently scheduled to be 145.800 MHz
The scheduled crewmember is Steve Bowen KI5BKB (***)
The ARISS mentor is AB1OC

Contact is go for: Mon 2023-05-01 12:43:15 UTC 79 deg (***)

Watch for Livestream at

The crossband repeater continues to be active.  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.

Comments on making general contacts

I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts.  First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk.  Also, one needs to be aware of their normal daily schedule.  I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts.  Hopefully this will help you better schedule your opportunities.

Typical daily schedule

Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours

The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well.

SSTV events are not that often.  So please check out for the latest information or watch for the ARISS announcements.

And don’t forget that the packet system is active.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

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. An email message received after a recent presentation:

"I really enjoyed Clint's presentation last night. The fact that he had taken the time to research and know something about his audience and welcomed interaction made it very informative and enjoyable. This was a refreshing change from many canned YouTube presentations I've tried to watch, which were poorly done, fuzzy video or muddy audio, or a badly prepared presenter stumbling his way through, with any valuable info lost along the way. Thanks for hooking this one up."
