The 2000 CQ WW Multi-Multi operation by the GM0B contest group from Benbecula, Outer Hebrides, Scotland, is documented, providing insights into a significant **DX contest** effort. This resource outlines the station setup, operational strategies, and team composition for a large-scale, multi-operator, multi-transmitter entry. It details the logistical challenges and technical solutions employed to achieve competitive results from a remote island location, a common scenario for **DXpedition**-style contest operations. The page offers a glimpse into the practical application of contest rules and the coordination required for a successful multi-operator effort. It serves as a historical record of the GM0B team's performance in a major international contest, allowing other contesters to compare operational approaches and understand the scale of such an undertaking. The information can be useful for those planning similar contest expeditions or studying past contest strategies.

Win EA6DDlog is a freeware logging application for Windows, developed by EA6DD Biel. It integrates features from existing software like Swislog, Urelib, Logger, and HamRadio Deluxe, presenting a Multi-Document Interface (MDI) similar to Logger. The program prioritizes simplicity, practicality, and operational speed, allowing functionality even on less powerful PCs. It does not require a formal installation; users can run it directly from a portable drive or any directory. This logging utility supports CAT control through Omnirig by Alex Shovkoplyas, VE3NEA, which is automatically installed if not already present on the system. It also offers QSL printing capabilities and connections to online callbook services such as QRZ and HamQTH for contact information. EA6DDlog includes an automatic update mechanism that checks for new versions upon startup, requiring internet access. For Windows Vista users, disabling User Account Control (UAC) is recommended for proper update functionality. The software is part of a broader development effort aiming for cross-platform compatibility, with future versions planned for Windows Mobile, Linux, and macOS.
