The ARRL Contest Results Database serves as a centralized repository for official scores and detailed breakdowns from numerous ARRL-sanctioned operating events. This resource typically features comprehensive listings of participants, their submitted logs, and final standings across different categories, modes, and bands. It allows hams to review their performance, compare results with other operators, and analyze contest trends over time, providing valuable insights into competitive amateur radio. Historically, the database has showcased the efforts of thousands of contesters, from single-operator entries to multi-operator, multi-transmitter stations. While the current status indicates scores are not immediately available, the database's primary function is to archive and present the outcomes of events like the ARRL DX Contest, Sweepstakes, and Field Day. This historical data is crucial for tracking individual progress, identifying top performers, and understanding the competitive landscape within the amateur radio community.

For radio amateurs seeking to verify contacts or identify stations from Tajikistan, the _Tajikistan EY Callbook_ serves as a dedicated online resource. This callbook, compiled and maintained by Irage M. Tursoon-Zadeh, _EY8WW_, offers a focused database of callsigns within the EY prefix region. It provides a practical utility for DXers and contesters aiming to confirm QSLs or prepare for operations involving stations in this specific geographic area, streamlining the process of identifying active hams. The resource's utility is particularly evident for those engaged in award programs like _DXCC_ or _WAZ_ where accurate callsign verification is crucial for credit. Unlike broader, worldwide callbooks, this specialized listing ensures high relevance and accuracy for its target region, reflecting the local expertise of EY8WW. Its direct focus on Tajikistan makes it a valuable, albeit niche, tool for operators with specific interest in Central Asian DX.

This online project guide details the construction of a homebrew boom microphone system. It details the assembly of a microphone shell from a 3/4" PVC pipe section and an end cap, requiring a drilled hole for a snug fit of the electret or condenser mic element. The internal wiring schematic specifies a **2.2 K** resistor and a **47 uF** polar capacitor for signal conditioning, with a circuit diagram provided for integration with IC-706 series transceivers. The guide outlines the use of CAT-5 cable for internal connections, incorporating strain relief at the rear of the mic shell, and an inline 3.5 mm jack to facilitate an external _PTT_ line, designed for a foot-mounted switch. Further construction involves fabricating a microphone shock mount from a 2-inch PVC connector, detailing the creation of four "fingers" and the insertion of screw-eyes for attaching elastic bands, which are twisted 180 degrees for tensioning and vibration isolation. A foam wind screen is also incorporated into the microphone assembly, secured with adhesive. The boom arm itself is repurposed from an articulated architect lamp, with the original lamp assembly converted into a **60 watt** resistive load for testing power sources. Microphone cabling is secured to the boom arm using wire ties, ensuring sufficient slack at hinge points to maintain articulation. The boom base is mounted to a bookshelf, requiring specific positioning to achieve proper microphone placement in front of the operator. Performance evaluation of the microphone system is conducted through on-air audio signal reports from other amateur radio operators.
