The Icom IC-7300 is a popular HF transceiver among amateur radio operators, known for its advanced features and performance. This modification guide focuses on enabling extended transmission capabilities, specifically for MARS and CAP frequencies. The instructions are based on the work of PA2DB and include detailed steps for removing specific diodes to unlock additional frequency ranges. Before proceeding with the modification, users are advised to take necessary precautions, such as ensuring the radio is powered off and using ESD protection. The guide emphasizes the importance of using appropriate soldering techniques and tools to avoid damaging sensitive components. A video demonstration is also provided to assist users visually in performing the mod. While this modification can enhance the functionality of the IC-7300, it is crucial to note that it may void the warranty and should be undertaken at the operator's own risk. The guide serves as a valuable resource for those looking to expand their operating capabilities with this versatile transceiver.

How to build the Quickie Pneumatic Antenna Launcher

A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables. Many hams connect the center conductor of the coaxial cable to one side of the dipole, and the shield to the other. Wrong!

The circuit is based on two AD8307 log amplifiers, which are connected to the forward and reflected ports on a directional coupler

Over 47 full-screen maps are available within _NAOMI_ (North American Overlay Mapper), a free Windows program designed for US and Canadian amateur radio enthusiasts. This mapping suite includes 9 backgrounds such as CQ Zones, ITU Zones, and ARRL Sections, along with 16 foreground layers like Counties, Areacodes, and Grid Locators. Users can calculate distances and bearings, track real-time mouse positions with continuous Grid-Locator data, and integrate with APRS for live station tracking via the FindU database. For a global perspective, the _Global Overlay Mapper_ (GOM) provides a world map, 8 continental maps, and 29 sub-continental maps, all with 12 active layers including Country Outlines, CQ/ITU Zones, and Prefix information. Both NAOMI and GOM offer feature-locate systems to jump to positions based on prefixes, capital cities, or Grid Locators, and provide customized beam headings and distance displays. The site also features _LogView_, a post-contest log visualization tool that analyzes Cabrillo-format logs by plotting QSOs on maps, supporting over 30 major contests like CQWW and ARRL DX, and allowing comparison with published results.
