Presents the design and construction of the OK2FJ Bigatas, a portable, automatically tuned vertical antenna covering 80 through 10 meters. It details two distinct control systems: one utilizing BCD band data from Yaesu FT-857/897 transceivers, and another employing voltage level sensing for the Yaesu FT-817. The resource provides specific instructions for building the antenna's radiating element, loading coil with switchable taps, and the control circuitry, emphasizing the use of readily available components. The article outlines the physical construction of the antenna, including the use of duralumin tubes for the radiator and a PVC tube for the coil form. It specifies coil winding details, tap points, and the integration of radial wires for ground plane operation. The control electronics section provides schematics and component lists for both the BCD decoder (using a 74LS42 IC) and the voltage comparator (using an _LM3914_ bargraph driver), enabling rapid, automatic band switching without the minute-long tuning delays common in other systems. Crucially, the antenna achieves rapid band changes, with typical SWR values centered on common operating segments, such as **3.7 MHz** for 80m SSB. It also discusses modifications for CW operation on 80m and the trade-offs between antenna efficiency and full-range automatic tuning on higher HF bands, where manual adjustment of radiator length is suggested for optimal performance on 15m, 12m, and 10m. The resource includes construction photos and a discussion of cable requirements for reliable operation.

A 15-pin data switch, typically a rotary-knob type designed for DB-25 connectors, forms the basis for this microphone selector project. The resource details the conversion process, which involves replacing the original DB-25 connectors with **RJ-45** or **RJ-12** jacks to accommodate modern amateur radio microphones. It specifically addresses wiring for radios like the Icom IC-706 series (including the IC-7000 and IC-703) and Yaesu transceivers such as the FT-857, FT-897, FT-817, FT-7800, FT-7900, FT-8800, FT-8900, FTM-100, and FTM-400. The design ensures all microphone lines are switched straight through, with separate contacts for external speaker/headphone jacks, allowing simultaneous switching. The project emphasizes the practical application of switching between a headset for net control and a hand mic for rag-chewing without repeatedly plugging and unplugging cables. It highlights modifications to the original concept, such as eliminating a separate PTT jack by integrating PTT into headset cables and building the external speaker cable directly into the selector. The article provides guidance on managing the non-color-coded wiring often found in these data switches by soldering wires one by one from old to new connectors, ensuring correct pin alignment. This approach simplifies the conversion, making it accessible for hams seeking a functional and cost-effective mic switching solution.

Tracing the foundational work of Guglielmo Marconi, this article details his early laboratory experiments in 1895, where he successfully transmitted wireless signals over 1.5 miles. It highlights his 1896 patent for a wireless telegraphy system in England and subsequent demonstrations, including signal transmissions up to 6.4 km (4 miles) on Salisbury Plain and nearly 14.5 km (9 miles) across the Bristol Channel. Marconi's work built upon the mathematical theories of _James Clerk Maxwell_ and the experimental results of _Heinrich Hertz_, proving the practical feasibility of radio communication. The resource further chronicles the formation of The Wireless Telegraph & Signal Company Limited in 1897 and Marconi's relentless efforts to popularize radiotelegraphy. A significant milestone was the 1901 transatlantic reception of the Morse code letter "S" from Poldhu, Cornwall, at St. John's, Newfoundland, using a kite-supported wire antenna, defying contemporary mathematical predictions about Earth's curvature limiting range. This achievement underscored the global potential of radio. The article also touches upon Marconi's later discoveries, such as the "daytime effect" concerning atmospheric reflection of radio waves, and his 1902 patent for a magnetic detector, which became a standard wireless receiver. His contributions earned him a Nobel Prize in 1909.
