This online tool is a specialized web-based utility for orchestrating multi-operator HF contest and DXpedition activities. This tool, _Rig2Cast_, assists station managers in meticulously planning operator shifts, ensuring adequate rest periods, and crucially, preventing operational conflicts such as assigning a single operator to multiple radios concurrently. It integrates support for SO2R operations and offers real-time simulation of operator requirements, a feature I've found invaluable in pre-event planning. The scheduling engine incorporates five distinct algorithms: greedy fairness balancing, round robin, maximum coverage, simulated annealing, and a fatigue-aware model. These algorithms enforce critical constraints like minimum/maximum shift durations and mandatory rest times across all radios, which directly impacts operator performance over long events. My field experience confirms that such robust constraint management is essential for maintaining peak efficiency during intense operations. Key features include distributed multi-station support, printable per-operator cards, flexible band activity windows, and real-time editable operator slots. The drag-and-drop shift management, coupled with full cross-radio swap support and smart constraint feedback (valid targets in green, invalid in red), streamlines complex scheduling tasks. The system's design ensures user data privacy, as no information is stored on the server; schedules are saved and reloaded locally.

The ZL1WTT resource details an experimental software-based Digital Amateur Television (DATV) system, demonstrating the multiplexing of up to six standard-definition (SD) and one high-definition (HD) channel utilizing _h264 compression_. The author encountered peak data rates reaching 32 Mbit/s, necessitating a shift to Freeview and Sky settings (22.5M Sym/s 3/4FEC) to manage bandwidth. The setup employs four networked computers, with a laptop functioning as the multiplexer to re-code PIDs for various inputs, including looped MPEG2 playlists, MPEG2 encoder card input from a VCR, satellite feeds, and an off-air UHF receiver. The system highlights the inherent flexibility of the DVB transport stream, supporting diverse formats such as MPG2, h264, AC3, and AAC. A significant advantage of this software-defined approach is the absence of video quality degradation from stored MPEG2 files to the displayed output, coupled with the ease of reconfiguring settings for MPEG2 encoder cards (e.g., size, bit-rate, frame rate, video input, coding format) and satellite receiver cards (e.g., frequency, LNB volts, symbol rate, FEC). The author also discusses the development of a new graphical user interface (GUI) using _Gambas_ for Linux, aiming to simplify configuration for this DATV project. Specific hardware components mentioned include Hauppauge WinTV PVR-150 and Nova-S plus cards, with a focus on optimizing analog video input via Y/C (S-video) to minimize frequency roll-off. The resource also provides insights into data rates for HD (1080i) content, recommending 8 to 12 Mb/s for optimal performance. Software utilized includes _Ubuntu Studio 10.04_, WinFF, VLC, and TMPGEnc Editor, underscoring the project's reliance on open-source tools and a foundational understanding of LAN networks and DVB transport streams.

QRZ Label is a Windows application designed for amateur radio operators to generate QSL labels using _Zebra (ZPL)_ label printers. It interfaces directly with QRZ.com to retrieve callsign and address details, and can import QSO log data from the QRZ Logbook. The software then formats this information into various label types, including standard address labels, envelope labels, greeting labels, and multi-QSO confirmation cards, all featuring an on-screen tabbed preview. The application supports the creation of QR-code labels, specifically a "QRZ Link" type, which can streamline the QSL process by providing a scannable link to the contact's QRZ.com page. This functionality enhances the traditional QSL card exchange with modern digital convenience. Developed by K7CTV, QRZ Label offers a practical utility for hams managing their QSLing workflow, providing a **free** solution for printing professional-looking labels directly from their station data. The software is distributed as a signed Windows installer.

QSL cards remain the preferred method for confirming QSOs, especially when received free via bureau. They capture the personality of the station operator and offer varied designs.

Despite modern alternatives, QSL cards retain their charm, but ensuring compliance with bureau requirements and understanding international practices is essential.

How to record the full contest audio into .mp3 file(s). t is possible to record the receiver's audio through the USB sound card in the radio (USB Audio CODEC), but only the transmitted SSB audio can be recorded, unfortunately not the CW.

Demonstrates an **Arduino-based** solution for the Icom IC-7300 transceiver, specifically addressing the operational inconvenience of switching between a CW paddle and a straight key. The project leverages the IC-7300's **CI-V bus** (Computer Interface 5) to provide instant keyer type selection and two preset power levels, bypassing the rig's menu system which otherwise requires eight button presses. This implementation utilizes the 3.5mm CI-V connector, leaving the USB port free for CAT control and the internal soundcard, a critical design choice for integrated station setups. The system's utility is particularly evident for CW operators who frequently alternate between keying methods during contesting or general operating. The article details the hardware setup, including an Arduino Nano, a 3.5mm jack for CI-V, and pushbuttons for control. An update in 2023 expanded the project to incorporate an 8-button Nintendo controller, enhancing user interface flexibility and demonstrating the adaptability of the initial design for further customization and feature integration.
