The NCDXF/IARU International Beacon Project schedule provides precise transmission start times for 18 beacons operating on 14.100 MHz, 18.110 MHz, 21.150 MHz, 24.930 MHz, and 28.200 MHz. Each beacon transmits every three minutes, cycling through its callsign at 22 WPM followed by four one-second dashes. The initial callsign and first dash are sent at 100 watts, with subsequent dashes at 10 watts, 1 watt, and 100 milliwatts, enabling **propagation analysis** across varying signal strengths. The schedule lists the minute and second within each hour for the first transmission of each beacon on its respective frequencies. This resource allows **DXers** and **contesters** to accurately predict beacon transmissions for real-time propagation assessment. For example, 4U1UN transmits first at 00:00 on 14.100 MHz, followed by VE8AT at 00:10, and W6WX at 00:20, continuing the sequence. The page also notes recent hardware upgrades, such as the installation of IBP 2.0 controllers with Icom 7200 radios at some sites, and provides status updates for beacons experiencing hardware failures or those not recently heard, aiding in troubleshooting and managing expectations for monitoring.

LF Utility Stations 110-148 kHz maintained by Marco, IK1ODO

Generating Morse code audio files from text input is the primary function of _MorseGen v1.2_, a utility designed for amateur radio operators. The software allows users to specify the tone frequency and words-per-minute (WPM) speed for the generated CW. A key feature is its ability to create a WAVE audio file containing the Morse code, which can then be used in various applications. The program also supports repeating the generated CW sequence at user-defined intervals, making it particularly useful for creating station identification signals or beacons. The practical application of this tool extends to automated station identification, especially for repeaters or digital mode gateways that require a CW ident. By producing a standard _WAVE file_, the output is compatible with most audio playback systems and software. This functionality provides a straightforward method for integrating custom Morse code messages into existing amateur radio setups, eliminating the need for external hardware keyers for simple identification tasks. The adjustable parameters offer flexibility to match specific operational requirements or personal preferences for CW characteristics.

This web article by VK3BLG details the construction of an experimental 70cm (432 MHz) circularly polarized patch antenna, intended for satellite communication. The resource provides dimensions, feed point specifications, and impedance matching considerations for a single patch element, with discussion extending to array configurations for circular polarization. Construction involves a copper patch element on a dielectric substrate, fed via a coaxial cable. The design is based on information derived from AO-40 satellite antenna specifications, focusing on achieving circular polarization for satellite reception. The article includes specific dimensions for the patch and feed points, along with impedance values. Validation is implied through on-air satellite reception reports, with initial signal reports of **1 S-point above noise** for AO-40 beacons using a grid reflector, improving to **3-4 S-points above noise** with a 2-turn helical feed. The author references a _NanoVNA_ for impedance measurements and discusses the relationship between slot and dipole antennas in the context of patch design.
