The Amateur Radio Association of Bahrain (ARAB) was established in 1970 to support the amateur radio community within Bahrain, operating under the **A92C** callsign. This organization provided a central point for local hams, fostering activities and representing their interests for several decades. Its historical presence is noted, even though it is no longer active. Unfortunately, due to unforeseen circumstances, ARAB ceased its operations. However, a new amateur radio society has since been formed in Bahrain, continuing the tradition of supporting local hams. Interested individuals can contact Fawaz, **A92AA**, for details regarding membership and the new society's activities, ensuring continued amateur radio presence in the region.

The 60-page PDF document, "Antenna Systems and Theory For The Non-Technical Ham" by Jim Abercrombie, N4JA, provides a foundational understanding of antenna systems. It explains basic antenna theory, including how antennas work, electromagnetic wave polarization, and the role of frequency. The resource details various antenna types such as flat top dipoles, inverted-V dipoles, shortened loaded dipoles, G5RV dipoles, Carolina Windoms, and end-fed configurations. Vertical antennas, including ground-mounted trapped verticals and inverted-L verticals, are also covered. Directional beam antennas like monoband Yagis, cubical quads, and log-periodic arrays are discussed. Propagation modes, including ground-wave, direct wave, and skywave propagation, are explained in detail, with specific attention to the D, E, and F layers of the ionosphere and their effects on HF communication. Technical concepts such as standing wave ratio, decibels, resistance, and reactance are defined, along with calculations for half-wave resonant dipole lengths. The document addresses feed-line radiation, balun applications, and critical antenna and tower safety considerations. It aims to dispel common antenna myths and educate hams on making informed antenna choices.

Operating RTTY digital mode, this resource provides access to various versions of the _2Tone_ software engine, specifically designed for decoding and encoding RTTY signals. It details the evolution of the software, highlighting a significant technical requirement change where versions 24.09b through 26.01a necessitate a PC CPU with the AVX instruction set, a crucial detail for operators considering system compatibility. The page lists numerous historical and current releases, enabling users to select a version compatible with their hardware and operating environment. The utility of 2Tone lies in its ability to interface with established amateur radio programs such as _N1MM Logger+_, WriteLog, and QARtest, enhancing their RTTY capabilities. While specific performance metrics like decoding accuracy or WPM limits are not quantified on this page, the availability of multiple versions, including those without AVX requirements, suggests a commitment to broad user accessibility. The software's integration with major contest logging applications indicates its primary application in competitive RTTY operations, where reliable decoding is paramount for achieving high scores.

eHam user reviews of the Yaesu FT-450 HF+6m t ransceiver

During a club's "Filetto Day" event, a comparative field test was conducted between a **Buddipole** antenna and a homemade 20/40-meter wire dipole. The author, IW5EDI, performed this personal evaluation from a mountain top at 1500 meters above sea level, utilizing a Yaesu FT-857D transceiver to switch between antennas. The observations on the 20-meter band indicated that the wire dipole consistently delivered significantly stronger signals compared to the Buddipole. Additionally, the Buddipole exhibited higher levels of **QRM** during the listening tests. The commercial Buddipole, known for its multiband capability and compact size with a self-supporting tripod, was contrasted with the simpler, larger wire dipole, which required a fiberglass fish pole for support. This direct comparison highlights practical differences in performance and deployment between a popular portable commercial antenna and a basic wire antenna in a real-world operating environment.
