Operating Aids : Beginner's Guides
  • Operating Practice - ON4WW - A must read guide for all new and old operators. This document was originally written with the prime focus on DXing and pileup behavior. Suggestions by proofreaders have been implemented; the document is not as narrowly focused anymore as originally intended. It contains hints, tips and tricks for newcomers as well as old-timers. Additionally there are VHF/UHF operational matters, DX Cluster ethics, COPS, Conflict Situations and more.

Technical Reference : HF Radios
  • Stingray Marine Transceiver - Recently, at the Ballarat Hamfest, the author acquired an old Marine transceiver for just $10, charmed by its sturdy construction and waterproofing. Made by Findlay Communications in Sydney, this crystal-controlled transceiver had been dormant but was reinvigorated with minor fixes. A manual was sourced, and further repairs were made, including an ingenious crystal oscillator replacement using an Si5351a controlled by an Arduino. The refurbished radio, complete with a fresh coat of paint and added customizations, is now operational for 160m AM and 30m SSB. A successful and cost-effective restoration.

  • RF-Quiet Solar PV for Ham Radio - This article discusses the potential for solar power systems to coexist harmoniously with amateur radio, challenging the notion that they are inherently incompatible. Drawing from personal experience, the author emphasizes the importance of selecting RF-quiet components, focusing on series-string Sunny Boy grid-tie inverters. The article also highlights considerations for system design and limitations based on roof orientation, shading, and array size. Overall, it presents a valuable perspective on creating a radio-friendly solar PV setup.

Technical Reference : Vector Network Analyzer
  • miniVNA PRO Modifications - The mini Radio Solutions miniVNA PRO is the only affordable vector network analyser (VNA) I know of that offers remote wireless operation. This is very interesting because it allows to measure the input impedance of HF antennas installed at height without having to deal with coax cable lengths, baluns nor common mode suppression chokes. However, to render the miniVNA PRO truly field proof, it requires a number of significant modifications.
