S21DX IOTA, 2026
S21DX AS-127 Islands on the air
Announcement:
We regret to inform you that our planned S21DX IOTA (AS-127) expedition scheduled for the end of this month has been postponed to a later date in 2026.
This decision was made after careful consideration of several factors, including:
1) Current logistical challenges and operational constraints in the region
2) Adequate resource availability concerns
We will announce the new activation dates once we have confirmed all necessary arrangements and resources. We appreciate your understanding and continued support.
73 de S21AM and S21RC
S21DX activated AS-127 back in 2009, and as the last 3 activations (2021, 2022 and 2024) ware from AS-140 with more than 35,000 QSO in the log, this time we are planning to activate from Kutubdia Island, Islands on the Air AS-127 and World Lighthouse on the Air (Lighthouse 1127)
We will try to operate the stations at least 18 hours a day (Depends on Generator Fuel fund and number of operators)
