Demonstrates the _SQUIRL Field Day Logger_, a specialized software tool designed for efficient contact logging during the annual ARRL Field Day event. The resource details its core functionality, which includes real-time logging to easily readable text files, with filenames structured by callsign, band, and mode (e.g., K8DAA-20M-SSB.txt). It highlights features such as a real-time history grid of previous contacts, a dynamic USA and Canada map displaying contact locations, and a duplicate checker that provides audio notifications and pre-fills class/section data for previously worked stations. The software also includes an ADIF export function, enabling users to transfer logs to other general-purpose logging programs. The software's design emphasizes simplicity and ease of use, allowing for rapid on-the-spot training, as noted by users like W4CMB. It supports various operating systems, including Windows 98 through 8, and has been successfully run on Linux via _Wine_. Key usability enhancements include a "double-size" feature for improved readability and a "Space Mode" for quick field navigation. The version history indicates continuous development from 2001 to 2013, with significant additions like the real-time Field Day Map in 2003 and ADIF export in 2004, which allows for seamless integration with other logging platforms.

Demonstrates the construction of a custom programming cable for Yaesu VX-7R and VX-5R handheld transceivers, enabling computer interfacing for memory management and frequency coverage adjustments. The resource details a six-transistor circuit design, powered by the computer's RS232 interface, utilizing readily available and inexpensive discrete components. It includes a complete bill of materials, specifying transistors like the _2N2222_ and _2N3906_, diodes, and resistors, along with a matrix board layout for compact assembly within a 75x50x25mm enclosure. The guide provides practical tips for working with matrix board, such as scoring and snapping, track cleaning, and component soldering order. It outlines the specific connection requirements for both the VX-7R (via Yaesu's CT-91 breakout lead with a 2.5mm stereo jack) and the VX-5R (via CT-44 or a four-section jack), detailing signal and ground pinouts. The author successfully tested three circuits, documenting the one with complete two-way communication, allowing users to program their rigs with software like _VX-7 Commander_ and achieve capabilities beyond commercial cables, including band adjustments.

VE3BDB's personal page serves as a dedicated resource for members of the Radio Amateurs of Canada (RAC) residing in the Ontario South Region. Bob Cooke, VE3BDB, previously held the position of Director for this region, offering localized support and information pertinent to the RAC's activities and initiatives within Ontario South. The page likely covered regional news, events, and specific guidance for local hams, reflecting his role in facilitating communication and engagement among the amateur radio community in that area. While the page is no longer active and Bob Cooke has transitioned from his regional director role to RAC Vice President for Field Services, its original purpose was to centralize information for Ontario South hams. The content would have been tailored to address regional concerns, promote local ham radio activities, and provide updates relevant to RAC members in that specific geographic area, directing users to the main RAC website for current information.
