Presents the construction and performance characteristics of the _Moxon Rectangle_ antenna, a compact, directional HF antenna design. It details the antenna's physical structure, emphasizing its robust build and ease of erection compared to traditional Yagis. The resource provides specific dimensions for building Moxons for the 10m through 40m bands, derived from _W4RNL_'s work, and discusses the critical element spacing for optimal performance. It also covers feeding the antenna with a simple choke balun and achieving a low SWR across the band. Compares the Moxon's performance to a two-element Yagi, noting its superior wind resistance and compact footprint. The author, _VK3BCY_, shares personal experiences with a 20m Moxon, reporting SWRs below 1.3 across the entire band and strong signal reports from DX stations with only 100 Watts. EZNEC Pro modeling data is included to illustrate gain and front-to-back ratios, confirming the antenna's high-performance claims. The article also briefly explores multi-band possibilities and reversible configurations.

Learn how to improve reception on the hf bands by setting up a noise cancelling system that nulls out local interference. This article describes a system using a 'Main Station Antenna' to receive a wanted signal and associated QRM, and an 'Auxiliary Antenna' to pick up unwanted interference. Gain and phasing controls are used to reduce/remove interference, leaving only the wanted signal. Tips are provided based on the author's personal experience, applicable to commercial noise cancelling products, kit form, or homebrew setups. Discover the importance of configuring the 'Auxiliary Antenna' to optimize your system and improve readability of wanted stations.

A friendly group of amateur radio enthusiasts based in Mutsch St. Lavington NSW Australia

DX Pedition to Galapagos will be active from October 26th to November 7th, from 6 to 160 meters (including Warc bands) on CW, SSB and Digi modes with at least 4 stations on the air at the same time.

The Ukrainian Contest Club (UCC) website details contest activities, including a March 2026 contest calendar compiled by _UW3WF_ that excludes specific "exotic" tests, mini-tests, sprints, VHF competitions, and events organized by Russian entities. It lists major contests such as the ARRL International DX Contest, Stew Perry Topband Contest, and CQ WPX SSB Contest, providing dates, times, modes, bands (e.g., **10-160m**), organizers, log submission methods, and deadlines. The resource also highlights Ukrainian participation in various international contests, noting specific callsigns that represented the UCC, and acknowledges new Ukrainian records, such as UW5Y's new record in the ARRL DX CW Contest. The site presents contest results and rankings, including the top 20 Ukrainian contesters in the World Amateur Radio Contesting Association (WARCA) rating for 2019-2024, with _UW1M_ ranked #18 globally and #1 in Ukraine with **26,490.32** points. It also details the club's 12th place finish among 155 clubs worldwide in the CQ WPX Contest 2024 (CW + SSB). The resource includes information on WRTC 2026 participants from the club and lists members excluded due to collaboration with adversarial entities, reflecting the current geopolitical context.

Learn how an experienced ham radio operator designed and built a compact shack in their motor home. Discover the considerations, challenges, and solutions involved in setting up a radio station in a small space without damaging the vehicle. Find out which radios were chosen for VHF/UHF scanning, HF communications, and QRP operations. Get insights on cabinet design, speaker placement, and radio cabling for a functional and portable ham radio setup on the road.

Demonstrates the construction of a portable 2-meter repeater system utilizing a **Yaesu DR-1X** transceiver, configured for both analog FM and C4FM digital voice operation. The design emphasizes portability, robustness, and effective thermal management, incorporating a "wind tunnel" airflow system with a fan to maintain transmit module temperatures at 38 degrees Celsius during continuous operation. The system integrates a diplexer, control head, and is housed in a compact, lightweight case weighing under 8kg, designed for single-person deployment. Covers practical considerations for field deployment, including power sources, antenna types, and the overall system architecture for public service events and emergency preparedness. The resource details the modular "wrap around" construction, showing how components like thermal switches for fan control and Anderson Powerpole connectors are integrated. It highlights the system's ability to provide reliable communications support for club activities and emergency communications.
