S21WD – Bangladesh DXpedition
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.
