Amateur Radio on the International Space Station (ARISS), in collaboration with
ARRL �The National Association for Amateur Radio�[1], plans to carry out a
special slow-scan TV (SSTV) experiment from the ISS on Wednesday, July 26,
2023. During the event, the Columbus Module Repeater, transmitting at 437.800
MHz, will carry a message to be received by teachers attending the ARRL
Teachers Institute on Wireless Technology[2] professional development class.
The pass will be over the Mid-Atlantic and New England area, with transmissions
scheduled to begin at 20:05 UTC (16:05 ET) and end at 20:20 UTC (16:20 ET). If
necessary, a�backup window is scheduled from 21:40 UTC (17:40 ET) to 21:55 UTC
(17:55 ET).�

Radio enthusiasts are welcome to download the message and follow along with the
event, but it is asked that all hams refrain from using the repeater for voice
contacts during the event.�This is a special experiment conducted through ARISS
and ARRL. Regular operations of the repeater should continue to take place in
voice mode only.

The primary goal of ARISS is to promote exploration of science, technology,
engineering, the arts, and mathematics topics (STEM/STEAM). ARISS does this by
organizing scheduled contacts via amateur radio between crew members aboard the
ISS and students. NASA has scheduled the next ARISS contact for scouts at Camp
William B. Snyder in Prince William County, VA.�The ARISS radio contact is
scheduled for Friday, July 21, 2023 at 1754 UTC (13:54 EDT). Scouts will ask
their questions of Astronaut Sultan Al Neyadi, amateur radio call sign KI5VTV,
who will use the ARISS radio station on the ISS to talk. The downlink frequency
for this contact is 145.800 MHz and may be heard by listeners within the ISS
footprint.

The ARRL�Teachers Institute on Wireless Technology is a donor-funded
professional development program designed to help classroom teachers elevate
their STEM�programs through the use of wireless technology. As a part of the
ARRL�Education & Technology Program[3], several sessions are conducted each
year, and the program continues to grow.

ARISS is a cooperative venture of international amateur radio societies and the
space agencies that support the ISS. In the US,�participating organizations
include�NASA's Space Communications and Navigation program (SCaN), the ISS
National Laboratory - Space Station Explorers, ARRL[4], and AMSAT.
