ARLS008 ARISS to Celebrate 20th Anniversary with SSTV Event

The Amateur Radio on the International Space Station (ARISS) program
is planning a slow-scan television (SSTV) event starting on
Thursday, July 20, and continuing for 2 days, to commemorate its
20th anniversary. Transmissions, set to get under way around 2125
UTC, will feature 12 images from past and present ARISS activities.
The SSTV signal should be available nearly anywhere on the globe at
some point during the event.

"Starting with our first meeting in November 1996, our joint
operations on Mir, becoming the first operational payload on ISS in
November 2000, to our [more than 1,100] school contact (so far),
ARISS's accomplishments have been tremendous," ARISS International
Chair Frank Bauer, KA3HDO, said, in first announcing the SSTV event
last. "We have touched the lives of many and inspired and educated
countless students to pursue science, technology, engineering, and
math careers."

The event plans to use a computer on the ISS Russian Segment, which
stores images that are then transmitted to Earth using the onboard
Kenwood TM-D710 transceiver, the ARISS announcement explained. Those
receiving the images can post them for public viewing.

SSTV signals will be transmitted on 145.80 MHz using FM. The SSTV
mode is expected to be PD120, with PD180 as a possible second
option. Free SSTV decoder software is available on the Internet.

ARISS asked educators to consider ways in which they might use this
opportunity to inspire their students by having them take advantage
of this chance to capture images directly from space to their

All ARISS events are dependent on other activities, schedules, and
crew responsibilities on the ISS and are subject to change at any
