Update April 6, 2026: OQRS on ClubLog as well as free of charge LoTW for everybody is available now.

The team is still processing log requests via email and will reply to them shortly.

Thanks for your support before and during the DXpedition!

Update April 5, 2026:  The S21WD DXpedition has successfully concluded operations from IOTA AS-140, with the team safely returning to Dhaka after completing its primary objective.
During the 12-day activity period, the team reached a total of over 73,000 QSOs, exceeding the initial target of 70,000 contacts. This marks a strong operational result under challenging environmental and technical conditions.

The team had the privilege to operate from Char Kukri Mukri, located in the very south of Bangladesh. Reaching this remote location required extensive logistics, including approximately 18 hours of travel one way within the country, using a combination of speedboat, tuk-tuk, cargo tricycle, ferry, and moped.

Prior to the DXpedition, all necessary permissions were formally secured. Licenses and approvals were granted by the Bangladesh Telecommunication Regulatory Commission (BTRC) for both individual operators and the group DXpedition license for IOTA AS-140. In addition, approvals were obtained from the Ministry of Environment and Forest of Bangladesh and the Bangladesh Police, ensuring full regulatory compliance for the operation.

A special thank you goes to Apon S21ABO and Anup S21TV for their outstanding involvement and commitment throughout the project. Their local support was essential for both preparation and execution.

Following the return to Dhaka, the team is currently regrouping at the hotel. Additional updates regarding the QTH setup and further impressions from the island will follow shortly, including selected photos from the operation.

The team will now begin processing log requests. Once completed, the full log will be uploaded free of charge to LoTW, and OQRS via ClubLog will be opened for all QSL card inquiries, as outlined on the expedition website.

Further updates and a final summary will follow.

Update March 22, 2026:  The S21WD team has successfully arrived in Bangladesh and is now active from IOTA AS-140, marking the transition from logistics to on-air oper-
ations.

On March 17, Jamie M0SDV arrived in Munich, where the team completed final preparations. The evening was dedicated to last packing activities, coordination with local supporters, and a joint dinner before departure.

On March 18, the team departed from Munich via Istanbul to Dhaka with Turkish Airlines. Despite the significant amount of heavy and oversized baggage, check-in procedures were handled efficiently with excellent support from airline staff. All flight segments and the transit in Istanbul were uneventful. Crucially, all equipment arrived in Dhaka complete and
without damage.

Customs clearance had been pre-coordinated with local amateur radio contacts, allowing for a smooth and efficient entry process. Upon arrival, the team received a warm welcome from local operators. After regrouping, equipment was repacked and expedition supplies were collected, as the team operates fully self-sufficient. A short breakfast in Dhaka was followed by final supermarket purchases. Special thanks go to S21ABO for preparing essential items in advance, which significantly eased logistics during the Eid Mubarak period.

The onward journey to the QTH required a multi-stage transport operation. After navigating through Dhaka’s busy old town, approximately 600 kg of equipment and supplies were loaded onto a ferry for an overnight crossing of around 12 hours. During the crossing, the team had an interesting exchange about amateur radio with the owner of the ferry company. After arrival, the journey continued by minibus for about one hour, including a stop for a local breakfast, before transferring to a final boat. At this stage, additional cargo was loaded, including around 500 kg of drinking water and a 10 kVA generator. Following arrival on the island (AS-140), a final 20-minute tuk-tuk ride brought the team to the QTH.

Immediately after arrival, work began in parallel on site exploration, shack setup, and antenna construction. The first signal as S21WD was transmitted on March 20 at approximately 17:00 UTC.

Initial operations revealed a much higher than expected level of local man-made noise, which had not been present during earlier site visits. In parallel, frequent grid power outages made it necessary to bring the expedition’s generator online early. The generator has been operating reliably since commissioning. However, one grid failure resulted in the loss of an amplifier and a power supply. Repair attempts have so far been unsuccessful.

Antenna deployment has progressed steadily. The 5-band Spiderbeam installed on the roof is performing well. The 3-band WARC Spiderbeam could not be deployed at the planned location and therefore had to be relocated to a green area in front of the house.

Further progress was achieved on March 22 with the installation of two large lowband verticals for 80m and 160m. Initial tests are very promising, particularly towards Europe. In combination with a receive flag antenna, which has shown clear improvements in signal-to-noise ratio, the first encouraging results on 80 meters have already been observed. Long beverage antennas are currently under preparation, and additional systems, including a 60m vertical and a QO-100 station, are planned for deployment shortly.

We have already been present during openings towards North America; however, current conditions combined with the local noise limitations have so far resulted in limited success.

Operational capacity is currently slightly reduced, as three operators are temporarily affected by health issues, limiting both antenna construction and operating activity. At the same time, strong support from local amateur radio operators has been instrumental in maintaining progress, and the team is very grateful for this assistance. The hospitality and catering provided by local hosts have been excellent throughout.

With the main antenna systems now largely in place and stable power ensured via the generator, the setup phase is nearing completion. The focus will now shift towards full operating mode, with top priority on locating and eliminating the noise source, followed by attention to openings towards high-demand regions such as North America and further optimization of lowband performance.

Further updates will follow as operations continue from AS-140.

Update March 6, 2026: Final Testing Phase Completed

During the past two weekends, the S21WD team carried out our final hardware and systems test at our logistics headquarters hosted by DG8MG. The objective was to assemble the complete station as planned for Bangladesh, operate all components in parallel, and validate stability under realistic multi-operator conditions.

Both Spiderbeam Yagi antennas, covering 12/17/30 meters and 10/12/15/17/20 meters, were fully assembled, mechanically aligned, and tuned. SWR and overall performance were verified across all bands. The antennas performed as expected and confirmed our operational concept.

For the low bands, we installed and verified functionality of our RX loop, BOG (Beverage on Ground), and Beverage antennas. Noise characteristics, directionality, and switching behavior were evaluated in detail to finalize our receive strategy. The internal RX distribution system was assembled and tested to ensure stable multi-receiver operation without interference or noise ingress.

Our QO-100 satellite station, provided by DXPatrol, was fully assembled and commissioned. Uplink and downlink performance, frequency stability, and integration into our logging and network infrastructure were success- fully verified. The satellite system is ready for deployment.

A key milestone was the full high-power “smoke test” of the RF chain. Three stations were operated simultaneously using our sponsored ACOM amplifiers, including two ACOM 1200S and one ACOM 500S. We tested all low-power and high-power bandpass filters as well as our triplexer configurations for 12/17/30 meters and 10/15/20 meters. The three stations were intentionally run in parallel using all triplexer ports at the same time. The system remained fully stable, with no inter-station interference or unexpected behavior. This confirms the robustness of our filtering and isolation design.

On the IT side, six laptops were configured according to our operational requirements. Operating systems were updated, required software installed, and all configurations tested in advance. In addition, we performed a network load test simulating more than 300,000 QSOs through our logging system. The network handled the load without performance degradation, and synchronization between stations remained stable.

Throughout this phase, we are in daily contact with our local team members in Bangladesh to ensure a smooth arrival and coordinated setup on site. Logistical details, infrastructure preparations, and operational planning are closely aligned. We are very pleased to have them on board. Their support and local coordination play a major role in the success of this project and are an essential part of the overall execution strategy. We are very much looking forward to finally meeting them in person very soon.

As part of the integration process, several smaller improvements were identified and implemented, including cabling optimizations, clearer labeling, and refinements to transport preparation. While none of these adjustments were critical, they contribute to higher reliability during field deployment.

Many local helpers supported us during both test weekends, contributing significant time and effort to setup, testing, and dismantling. Over the past months, a substantial number of man-hours have gone into engineering, logistics planning, and preparation. A DXpedition of this scale is only possible through coordinated teamwork behind the scenes.

We are now in the final phase of packing all equipment for transport. Our departure is scheduled for 18 March, now less than three weeks away. With the successful completion of this final integration test, we move into the execution phase with confidence in our technical setup.

Update February 15, 2026:  The countdown is on for S21WD – Bangladesh 2026.

Our team is scheduled to arrive at our QTH on March 20th, with on-air activity expected to begin shortly after arrival. We plan to remain active through April 1st, giving us a full 12 days of operation from IOTA AS-140.

During the activity period, we also intend to participate in the CQ WPX SSB Contest in a Multi-Operator category, operating as S21WD.

We are now in the final preparation phase. Equipment logistics, licensing, station configuration, and operational planning are essentially completed. The remaining steps focus on final checks, packing, and deployment readiness.

S21WD is a youth-driven initiative under the umbrella of the Next Generation DX Club e.V., combining technical ambition with international cooperation and on-site engagement.

We look forward to working you from Bangladesh!

Update February 2, 2026: Yesterday, a small team of local supporters met at our logistics HQ to build and test the 60 m vertical antenna for our upcoming Bangladesh operation.

The antenna was built from scratch and the results were convincing: during testing it performed exceptionally well, allowing us to work plenty of DX with ease. The smoke test was a clear success.

In parallel, we invested significant time into coax cable verification. Around 600 m of coax in various lengths were measured, checked, and problem spots resolved - because without reliable coax, there are no signals on the air.

Simple as that.

We also upgraded our antenna patch panel, keeping the design simple but improving grounding for better robustness and RF performance.

Preparation is key - and this was another solid step forward for S21WD.

Update January 26, 2026: We have officially received our LoTW certificate recently. Another important building block is now in place, and the project is coming together very nicely.

A big thank you to the ARRL for providing the certificate, which enables us to upload all QSOs daily and free of charge to LoTW for the global amateur radio community.

Update January 20, 2026: With around two months remaining before departure to Bangladesh, preparations for the S21WD – Bangladesh 2026 DXpedition are now well advanced.The team plans to operate from IOTA AS-140 (Khulna / Barisal Region group) at the end of March 2026.

During the past months, many evenings and weekends were spent at DG8MG’s QTH, which serves as the main preparation and logistics location. All major antenna systems were assembled and carefully tested there. These tests helped confirm correct assembly procedures, transport concepts, and overall system reliability well before departure.

We would like to thank our local radio friends who supported the team during these preparation sessions once again. They spent many hours assisting with equipment tests and sharing their experience and knowledge. Their contribution was essential and made the current level of readiness possible.

As departure is getting closer, the focus has moved from antennas to station infrastructure. Work is ongoing on power distribution, station layouts, cabling, networking, and backup concepts. Full system tests of the complete stations – including radios, amplifiers, filters, and software – are planned for the coming weeks.

The DXpedition will be active for 12 days and operate on 160 through 10 meters, including 5 MHz (60 m), using CW, SSB, RTTY, and FT8. In addition, activity via the QO-100 satellite is planned using CW, SSB, and FT4.

The Team

The project is organized by the Next Generation DX Club e.V. and carried out by an international team:

Philipp Springer (DK6SP, 28) – Team Lead
Sven Lovrić (DJ4MX, 23) – Co-Lead and QSL Manager
Team Members:

Jamie Williams (M0SDV, 25)
Leon Hellmich (DL3ON, 21)
Rudranil Sarker Apon (S21ABO, 23)
Anup Kumar Bhowmick (S21TV, 46)
The average age of the team is approximately 27 years, combining youth driven DXpeditioning with experienced local participation.

Around 400 kg of equipment are currently being prepared and packed. Most of the equipment will be transported by the team as additional checked luggage on the flights. This requires careful weight planning and standardized packing, while allowing direct control over all critical equipment.

Following the successful DXpeditions 8R7X – Guyana 2024 (more than 73,000 QSOs) and V73WW – Marshall Islands 2025 (more than 103,000 QSOs), the team is highly motivated to continue this success with S21WD – Bangladesh 2026.
