Optimizing antenna portability for QRP field operations often involves trade-offs between efficiency and physical footprint. The PAC-12 antenna project addresses this by presenting a **multi-band portable vertical** design, specifically tailored for amateur radio operators who travel frequently and utilize compact QRP transceivers like the Elecraft K1/K2 or Yaesu FT-817. This design emphasizes ease of homebrewing using readily available hardware store components, allowing for customizability and repair in the field. The project details the construction of a sectional aluminum rod base, interchangeable loading coils for various HF bands, and a telescoping whip. Key components include 1/4-inch aluminum rod, PVC risers for coil forms, and a BNC feedpoint insulator. The design prioritizes a breakdown length of 12 inches or less, making it highly packable for travel, while still achieving competitive efficiency, as demonstrated by its first-place finish in the HFPack antenna shootout at Pacificon 2001 against a 1/4-wavelength wire vertical. Comprehensive instructions cover whip preparation, **loading coil construction** with specific dimensions for bands from 40m to 10m (with an untested 80m approximation), base section fabrication, and feedpoint insulator assembly. The resource also includes guidance on radial deployment, threading aluminum rod, and showcases various PAC-12 builds by NJQRP Club members, illustrating its adaptability and widespread adoption among QRP enthusiasts.

The _Sci.Electronics FAQ: Repair: RFI/EMI Info_ document, authored by Daniel 9V1ZV, provides a detailed analysis of computer-generated RFI/EMI, focusing on its impact on radio reception. It identifies common RFI sources such as CPU clock rates (e.g., 4.77 MHz to 80 MHz), video card oscillators (e.g., 14.316 MHz), and even keyboard microprocessors, all of which generate square-wave harmonics across HF and L-VHF regions. The resource outlines a systematic procedure for pinpointing RFI origins, including disconnecting peripherals and using a portable AM/SW receiver with a ferrite rod antenna to localize strong interference sources. The document categorizes RFI mitigation into shielding, filtering, and design problems, offering practical solutions for each. It recommends applying conductive sprays like _EMI-LAC_ or _EMV-LACK_ to plastic casings of radios, monitors, and CPUs to create effective Faraday cages, emphasizing proper grounding and avoiding short circuits. For filtering, the guide suggests using line filters, ferrite beads, and toroids on power and data lines, and small value capacitors (e.g., 0.01 uF for serial/parallel, 100 pF for video) to shunt RFI to ground. It also discusses the use of bandpass, high-pass, low-pass, and notch filters on the receiver front-end or antenna feed to combat specific in-band noise.
