We will rerun the pass predictions for the upcoming #SSTV activity scheduled for 03/10/25 - 06/10/25 to see if this reboost of the #ISS has also affected the passes over the #GX4WAW clubhouse in #IO81qk

Check our website for updates probably from 02/10/2025

in the past we have activated former Light Vessel 56 now the Cabot Cruising Club's base of operation in Bathurst Basin in Bristol as #GB0CCC

Sadly we can't do that this year but there should be a few hundred lighthouses being activated around the world

Oooh! More #ISS #HamRadio excitement

Much more specialised than the recent #SSTV activity there will be some people with the capability to receive the test signals and report so if you can please do

ARISS - Amateur Radio on the International Space Station @arissintl.bsky.social · Jul 24

The installation of HamTV is on the ISS work schedule for next week. Successful completion could mean test transmissions going out beginning on Tuesday.

Check the graphic for more info.

The image shows a HamTV unit, part of the amateur television system on the ISS, with a schedule for installation on Tue, 29-July, from 07:55 to 09:55 UTC (3:55 to 5:55 AM ET). A successful install should have the unit active and transmitting a carrier. Reception reports are requested via social media. HamTV uses MPEG-2 video with DVB-S protocol, transmitting on 2395 MHz (2.395 GHz), primarily for educational contacts. More info is available on the BATC wiki, ARISS discussion, Discord, and live feed when available. (2014 NASA photo of the HamTV unit in the ISS Columbus module.)

With the SSTV event finishing yesterday, the ARISS radios are back to "norminal" operation. Enjoy!

The image provides an update on the ARISS (Amateur Radio on the International Space Station) radio status as of July 21, 2025.

- **Columbus Module Radio**: Configured as a crossband voice repeater with a downlink of 437.800 MHz and an uplink of 145.990 MHz (PL 67 Hz).
- **Service Module Radio**: Configured for simplex packet operations (APRS) with an up and downlink frequency of 145.825 MHz.
- **Casual Crew Activity**: Unscheduled amateur radio contacts may occur, and listeners can expect to hear the crew on the crossband voice repeater.

The image also includes a NASA photo of astronaut Randy Bresnik mounting one of the ARISS ham radio antennas during STS-129 in 2009.

It is worth reading fully

ARISS - Amateur Radio on the International Space Station @arissintl.bsky.social · Jul 22

Yesterday, ARISS-USA filed a petition to the FCC to deny AST & Science’s application to operate in the 430-440 MHz spectrum.

For the entire statement, read the PDF at the FCC website:
www.fcc.gov/ecfs/filing/...

The image discusses a petition from ARISS-USA to the FCC to deny AST & Science's application to use the 70 cm amateur radio band (430.00 to 440.00 MHz). ARISS-USA argues that their operations, including those on the ISS and SpaceX Dragon, rely on this band, and AST's use could interfere with communications, especially for deep space missions to the Moon and Mars. They highlight the potential for interference with their ground stations, including the Bluebird network, and the ISS crew's communications. The petition is signed by Frank Bauer, KA3ADO, ARISS-USA Executive Director.

Check your ISS passes! There are just 24 more hours in the Series 28 SSTV event.

Listen in on 145.800 MHz for the transmissions. They are sent from the ISS on a two minutes on - two minutes off schedule.

Given that this authored or edited by the ARRL Handbook editor, it is probably going to have a USA bias. But it'll probably translate well enough to be of interest

So the good thing about this #SSTV activity period from the #ISS is that it is at a civilised time, the bad thing is that there's a lot more local noise than in the small hours of the morning

G4WAW: South Bristol ARC @sbarc.co.uk · Jul 10

I've just looked back at the original data and I'm not sure we have lost a pass, we might have put an early one in before the original start time in error

Have to say this is a more civilised timing (yes I know orbital trajectories are fixed) than the last activity period over IO81QK
