Broadcastify currently hosts 7,266 live public safety radio feeds, providing real-time scanner audio for police, fire, and EMS operations. The platform aggregates transmissions from various emergency services, allowing users to monitor local dispatch and response activities across numerous geographic areas. It functions as a centralized hub for streaming publicly accessible radio traffic, distinctly separate from amateur radio operations or traditional _DXing_ pursuits, focusing instead on unencrypted public safety communications. The resource primarily focuses on public safety radio systems, which typically operate on VHF/UHF frequencies, often employing trunked radio system architectures. It does not involve amateur radio bands but rather provides direct access to publicly available emergency service communications. The content is organized into categories like Top Feeds, New Feeds, and Official Feeds, facilitating navigation through its extensive catalog. Broadcastify's utility stems from its efficient aggregation and streaming infrastructure, offering a direct link to local emergency dispatch and response. The platform also details its operational mechanics and lists official providers, indicating a structured approach to content sourcing and distribution.

The homemade CW paddle key design, inspired by a QRP homepage, utilizes soldered PC board material for its construction. The builder, DL5NEJ, modified an existing design to achieve a smaller footprint, preferring a compact setup for portable operations. This paddle was specifically built to complement a Wilderness Radio SST20 QRP transceiver kit, demonstrating its suitability for low-power operations. The project details suggest a straightforward assembly process, with the primary components being readily available PC board scraps. The design emphasizes simplicity and functionality, aiming to provide a reliable keying experience comparable to commercial paddles like the Bencher. Performance evaluations indicated the simple paddle operates effectively, prompting further exploration into similarly minimalist QRP rig designs. Additional construction details for a similar paddle are available from PA0CMU.

Over 70 international contests are supported by YPlog, a Windows-based logging and radio control program designed for amateur radio operators. This software integrates with various digital mode applications like _WinPSK_, _HamScope_, and _MMTTY_, facilitating partially automated log entry for modes such as PSK31, CW, and RTTY. It provides comprehensive logging capabilities including QSL label printing, beam headings, and dup-checking, alongside award tracking for DXCC, ITU/CQ zones, IOTA, Grid Locators, and Counties. The program offers advanced contesting features, including multi-multi or multi-2 networked operations with automatic log data sharing, multiple Cabrillo submission formats, and configurable CW keyboard layouts. Device support extends to TR-compatible CW keying, SO2R control with Top-Ten devices like the DX-DOUBLER, and internal W9XT digital voice keyer integration. YPlog is notable for its support of the _OK1RR DXCC_ country resolution files, providing a robust historical DX compendium. Beyond logging, YPlog includes two freeware utilities: one for computing design parameters for coaxial traps and another for displaying and printing azimuth and Mercator maps from the operator's QTH. The software runs on Windows 95/98/ME/NT/2K, with a recommended screen resolution of 1024x768. Registration costs **$50.00 US** to unlock all features, including full contesting capabilities and rotator control.
