This week, we’re looking at a few items that touch on practical station improvements and some interesting receiving setups. There’s a clever Arduino project for those running Icom 7700/7800 rigs, letting you command an external tuner remotely – something that comes up often when optimizing feed lines for various bands. We also have a piece on building a phase-controlled receiving array, which is always worth revisiting for weak signal work, especially on the lower bands where noise can be a real challenge. For the vintage gear enthusiasts, a collection of ‘boatanchor’ photos might spark some nostalgia or inspire a restoration project. And for those curious about specific receiver performance, a detailed review of the ICOM IC-R9000 offers insights. Finally, a look at a KiwiSDR operating from Iraq provides a unique listening post, and a homebrew QRP transmitter build offers some solid construction tips.
This article presents an Arduino-based solution for Icom IC7700 and IC7800 transceivers. It enables a remote tuner
call command, beneficial for operators using external tuners like the MFJ 998RT to manage antenna impedance.
This resource details the construction of a phase-controlled receiving array. It's designed for QRP low band
fox hunting, offering improved noise reduction and enhanced reception of weak signals for operators in challenging RF environments.
This website is dedicated to 'boatanchors,' a term for classic tube radio equipment. It features numerous pictures of popular vintage radios from manufacturers like Hallicrafters and Heathkit, appealing to collectors and restorers of historical amateur radio gear.
This is a comprehensive review of the ICOM IC-R9000 receiver. It covers the unit's specifications, performance characteristics, and features, providing valuable information for operators considering this high-end receiving platform.
This entry highlights a KiwiSDR online receiver situated in Baghdad, Iraq (locator LM23fh). It allows users to listen to HF communications across multiple bands (10-80 meters) using an MLA 30+ antenna, offering a unique remote listening experience.
This resource details the construction of a GM3OXX OXO QRP transmitter. It focuses on practical aspects like using FT-243 crystal holders and enclosure considerations, providing guidance for homebrew enthusiasts building low-power rigs.
