S21DX team member lineup is ready for their 2024 IOTA DXpedition. Many youth operators are participating this time who will gain substantial know-how of operating, antennas and propagation. Mainly they will have the start of doing DXing and handling pileupS. YL Raka who was volunteer for the last two S21DX activations in 2021 and 2022 will join this time as an operator, her callsign is S21YLJ. Pictures show a few team members busy making new antennas for low band DXing and the team – [tnx S21RC].


  • [AUGUST 18] –

Dates: December 13-19, 2024. Proposed team for Dhal Char, IOTA AS-140 2024 activity is: S21RED, S21YLJ, S21AM, S21FIA, S21TG, S21ACP, S21MK, S21D, S21DW, S21OM, S21MOB, S21RC, S21TQ, S21BK and S21OD. Check here for rigs, antennas, stations and more. 

  • [JUNE 29, 2024] – 

We are planning to activate another IOTA in this December. Our main goal this year is to focus on hands on training and capacity building for the local HAMs to understand different types of HF antenna, Propagation and Pileup handling. We hope in coming days we will see more HF station doing DXing from S2.

After checking all the islands in the two groups, considering Logistics, Transport and Cost we have decided to do the IOTA from the same island as before (Dhal Char, AS-140). The other nearby island is not suitable due to antenna orientation problem and also drinking water is not available in all of them, some are not inhabited.

Why not join the team – see details here (last date for application is 31st July). DX-World is very happy to once again be official news outlet for S21DX. Check out the 2022 activity documented below:
