A 1:1 current balun by N5ESE

This article describes a simple, inexpensive, dipole antenna that will rival the performance of a ten-meter beam.

The terminated tilted, folded dipole T2FD is a little known antenna that performs excellently. Compact in size compared to a half-wave dipole the T2FD provides signal gain, wide frequency coverage, and exceptionally low noise characteristics.

NuMorse 2.20.0.0 for Win 7/Win 8/XP/Vista/Win 10 A complete rewrite of the original NuMorse used by thousands of radio amateurs to gain and upgrade their licenses. NuMorse offers an intermediate feature set that is somewhere between the lean and mean NuCode program and the vast array of features supported by NuMorse Professional. But NuMorse is no cut-down program. It has several unique features not found in other Nu-Ware products as well as a compact and intuitive set of controls that you will be able to learn quickly.Product is no more developed and out of support.

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.

BroadWave Streaming Audio Software facilitates the broadcast of live and pre-recorded audio content over the internet, operating as a server on Windows PCs. It supports streaming from over 40 audio formats, automatically converting files for optimal delivery. The software allows for up to 8 separate live audio streams from a single PC and can serve up to 500 simultaneous listeners, contingent on available internet bandwidth. Listeners access streams directly through standard web browsers, eliminating the need for specialized client software. The free version, available for non-commercial applications, includes most features and does not expire. It supports recording live audio streams to WAV files and displaying the number of connected users. The professional version offers additional capabilities such as custom banner displays and integration with Zulu DJ Software for live mix streaming. System requirements specify Windows 7/8/8.1/10/11, with older versions compatible with earlier Windows OS releases. The application is designed for internet radio broadcasting, podcasting, and sharing live events, providing a direct method for **audio distribution** to a global audience without complex setup.

W5ALT Indoor Vertical Antenna is a base loaded vertical antenna that can be tuned on almost all HF bands by adjusting a big coil. Operating a ham radio station from an apartment in Maracaibo, Venezuela, the author demonstrates effective communication with over 100 countries using a custom-built indoor vertical antenna. Addressing common misconceptions, the design uses a balanced approach with radials and a base-loaded vertical element made from affordable materials. The antenna fits discreetly indoors, covers 6 to 40 meter bands, and achieves acceptable SWR with an MFJ tuner. Despite limited space and typical apartment challenges, the setup enables reliable DX contacts, confirmed by numerous QSL cards, proving indoor antennas can perform well in constrained environments.
