Remember Isabella? The 8 year old made news thanks to a #HamRadio contact with aboard the ISS last year.
Well she is still interested in radio and is dreaming of a career in the space industry!
The graphic below has all the latest thanks to her dad .
ARISS is aware of intermittent changes in received power levels in today's SSTV signals. Problem is being looked into. Look for updates here and at our FB acct at Amateur Radio on the International Space Station (ARISS) on changes in the operation status.

Great photo of the ISS taken the night of Aug.19 by ham operator and amateur astronomer Kevin Parker VK4BKP as the ISS passed over Mackay Queensland Australia.
Amazing resolution for an 8" SCT. Guess Kevin really knows how to set up a telescope for astrophotography.
Congratulations to . She participated in #AmateurRadio VE testing last month and recently received her call sign!
Here’s a frequently asked question, so let’s get opinions from the group. What’s the best handheld for working the ISS on voice? Photo is Owen Garriott’s HT for reference.
ARISS SSTV event update:
It appears yesterday's intermittent image signal problem is no longer an issue.
Your posts at the ARISS SSTV Gallery look great!
All the Best and Keep up the posting.

We're excited for tomorrow's SSTV experiment with the Teacher's Institute just after 4 PM ET.
An ARISS ground station will send the SSTV images several times to the TI students via the repeater.
Please give way on the repeater uplink, & enjoy the download!
MAI-75 SSTV experiment event is planned where images
are downlinked during orbits over Moscow on June 9 and 10. Radio enthusiasts in the orbital path should have the opportunity to capture these images. Schedule at our FB at Amateur Radio On The ISS (ARISS)

The ARISS repeaters are back online following yesterday's spacewalk according to online reports at amsat.org/status/
Thanks to the crowd for keeping this up to date!
The status page is showing 13 recent reports of crew operating the #HamRadio on the ISS.
If you want to give it a try, remember it's a crossband contact. Set your downlink to 437.800 and your uplink to 145.990 and PL of 67 Hz.

It was a great year for ARISS, including our 1,500th student contact and first student contact in Antarctica!
Was the #ISS in your log this year?
Amateur Radio on the International Space Station (ARISS) plans to have its ARISS InterOperable Radio System (IORS) in crossband repeater mode for ARRL Field Day. For more details visit our website at ariss.org or on FB at Amateur Radio on the ISS (ARISS).
Remember in your #AmateurRadio license studies you were told to use "only the power necessary" when transmitting?
This is especially true when using the ARISS repeaters aboard the space station!
I received a report from two sources that Kjell Lindgren was heard earlier today, June 15, using the ARISS D710 radio in repeater mode to talk with hams around 4:30 ET this afternoon. It might pay to listen in for more random contacts during passes over your area.
The Amateur Radio on the ISS (ARISS) Program is seeking education institutions to host an Amateur Radio contact with astronaut on board the ISS. New Proposal Window is Oct 1, 2021 to Nov 24, 2021. Details are at our Facebook at Amateur Radio On The International Space Station.
Enjoy the experiment!

Last week a ham asked, "Why didn't a crew member answer when I called NA1SS (or OR4ISS) on the last pass?"
Just like you, the ISS crew does #hamradio in their spare time, which is very rare on the .
Here's how to listen for the crew. Share your other tips below!
ARISS SSTV Event Update:
Concerning the ARISS SSTV Event that opens today April 11 and runs through April 13, SSTV diplomas will be available at ariss.pzk.org.pl/sstv/ . More details on this are at our FB at Amateur Radio on the ISS (ARISS).
Great question from social this week asking about what equipment do we recommend for our ARISS educational contacts?
Check the graphic below and read why those items are important in the PDF on ARISS.org.

Listening for a school contact or ready to work the ISS on the next pass? Here are the frequencies you'll need to be successful.
After engaging several sources, it appears ISS packet is currently working again. No replacement gear has been delivered to the ISS yet, so we are still working with the current gear. We may still experience off times until equipment is replaced.
