The TY0RU DXpedition to Benin in 2022 achieved over **100,000 QSOs** from Cotonou, IOTA AF-051, operating across 160m through 6m bands using CW, SSB, and FT8 modes. The operation involved a team of 12 operators, including _F5RAV_, _F4WBN_, and _F1TCV_, utilizing multiple stations with transceivers like the Icom IC-7300 and IC-7610, paired with amplifiers and various antennas such as verticals, dipoles, and a 4-square array for 40m. The expedition's log is available on Club Log, supporting OQRS for both direct and bureau QSLs, with F5RAV serving as the QSL manager. The site details the team's travel, setup, and operational challenges, including local conditions and equipment deployment, offering insights into the logistical complexities of activating a rare DXCC entity. Donors are acknowledged, and a photo gallery documents the activity.

Presents the S21WD DXpedition to Bangladesh (IOTA **AS-140**) scheduled for 2026, organized by the Next Generation DX Club e.V. It outlines the project's progress, including final hardware and systems testing, and the team's successful arrival and activation from the target location. The resource provides a concise summary of Bangladesh, covering its geography, cultural aspects, and economic landscape. The page includes the Clublog Most Wanted ranking for Bangladesh, categorized by continent and mode, as of January 2026. The DXpedition aims to achieve over 70,000 QSOs across CW, SSB, RTTY, and FT8 modes, with a specific focus on RTTY (targeting over 2,000 QSOs) and **lowband** operations. The team plans a Multi-Single entry in the ARRL CW 2026 contest. QSO data will be uploaded to Clublog and LoTW, with Clublog livestream and daily free LoTW uploads anticipated, contingent on stable internet connectivity. The S21WD callsign corresponds to CQ Zone 22 and ITU Zone 41. Further details include a preliminary bandplan, FT8 operating guidelines using MSHV software, a VOACAP DX Prediction link, and an azimuthal map centered on Bangladesh. QSL services are managed by DJ4MX via Clublog OQRS, offering direct, bureau, and LoTW options, with daily LoTW uploads expected.
