7. A Compact and Stealthy Field Portable Antenna

   Antennas/Portable
   In the quest for an ideal field portable antenna, the author recounts experiments involving various wire configurations. While a previous candidate, a 41ft random wire, proved effective but lacked stealth, the search led to a surprising rediscovery of a design previously rejected—the Rybakov Antenna. With a focus on simplicity, rapid deployment, and multiband capability, the author explores the versatility of a 26ft Rybakov, avoiding the halfwave trap. The article delves into the antenna's performance and its potential as a discreet, resonant solution for field operations, addressing the challenges encountered during a POTA activation. Additionally, the Unun/Balun design used in conjunction with the Rybakov Antenna is discussed, providing insights into achieving a balanced system.

8. IC705 GoBox: A Portable Windows-Based Solution for All-Digital Modes

   Technical Reference/Ham Radio Go Kits
   This project details the creation of a portable GoBox housing an IC705, Windows 11 PC, and Bluetooth microphone. The robust setup, enclosed in a weatherproof Hofbauer Explorer Case, ensures stability and functionality for QRP and emergency radio activities. The aluminum-mounted devices minimize RF interference, and a built-in LifePO4 battery powers the 10.1 TFT touch LED monitor, providing approximately 12 hours of use in receive mode. With a focus on grab-and-go versatility, this GoBox stands as an efficient solution for outdoor ham radio operations.

9. Understanding Impacts of 75-ohm Devices in 50-ohm Systems

   Technical Reference/Coax Cables and Connectors
   This article explores the implications of using 75-ohm devices, common in TV setups, within 50-ohm systems. While mismatched cables and connectors may lead to minimal consequences in receive-only setups, potential losses and reduced isolation in splitters and taps are examined. The article concludes that, for general applications, inexpensive TV-type components can offer reasonable performance with some trade-offs

10. Enhancing Frontend Performance with Optimized Band Pass Filters

    Technical Reference/Filters
    This article explores the nuanced design challenges of Band Pass Filters (BPF) in radio receivers, balancing low insertion loss, high stop band rejection, and narrow bandwidth. The focus is on the "Series-Trap, Shunt-C" topology, resonator count impact, and meticulous layout design for superior stop band performance across various frequency bands
