Coordinamento del radioascolto``Official website, in italian

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.

Operating magnetic loop antennas requires careful consideration of RF safety, particularly regarding near-field magnetic field intensity. This resource presents calculations for magnetic field strength (H-field) at various distances from a magnetic loop, emphasizing that the H-field is significantly higher than the E-field in the near-field region due to the inductive nature of the radiating element. It provides specific formulas and examples for determining safe operating distances based on power levels and loop dimensions, crucial for compliance with RF exposure limits. The analysis compares calculated H-field values against FCC and ICNIRP maximum permissible exposure (MPE) limits for controlled and uncontrolled environments. It demonstrates that even at QRP power levels (e.g., 5W), the H-field can exceed MPE limits within a few feet of the antenna, necessitating greater separation distances than often assumed for electric field considerations. The practical application of these calculations helps amateur radio operators configure their stations to ensure personnel safety and regulatory compliance when deploying compact, high-Q magnetic loop antennas.

For radio amateurs seeking to identify or verify callsigns from Bosnia and Herzegovina, an online callbook service offers a direct search utility. This resource focuses exclusively on the _T9_ prefix, allowing users to input a specific callsign and query a dedicated database. It serves as a historical reference for contacts made prior to its last update. The utility provides a straightforward interface for callsign lookups, presenting results based on data compiled up to _July 31, 2000_. While the information is static and not current, it remains useful for confirming older contacts or for historical research within the amateur radio community. The service is maintained by _Boris Knezovic, T93Y_, offering a focused resource for this specific geographic region.
