This article describes the development of two tunable antennas each consisting of three interconnected small loops and capable of providing excellent DX performance. The aerials are home-constructed, and located in a very small garden with a minimum of visual impact on the neighbours and are low enough in height to avoid the attention of UK planning authorities. -

Operating the UoSAT-2 (OSCAR-11) satellite, launched in 1984, presents unique challenges due to its age and current eclipse schedule. This resource provides a historical archive of news, telemetry data, and specialized software for decoding its 145.826 MHz FM beacon. It includes tools like _CTERM_ for terminal emulation and capture, and U2TM for processing ASCII telemetry, enabling hams to analyze the satellite's health and performance. The site also offers audio samples of the beacon and S-band signals, along with details on hardware and software decoders. Reception reports are actively solicited for the satellite's intermittent transmissions, which occur for less than an orbit every 21 days during its eclipse period. The site details how to process raw telemetry data, including instructions for skipping initial frames to improve decoding accuracy with U2TM. It also provides software like SATILL for predicting solar eclipses and tools for determining the satellite's spin period from magnetometer or solar array telemetry, offering insights into its operational status despite its advanced age. -

The MFJ-971 portable antenna tuner, as stock, lacks a bypass switch and sufficient inductance for efficient 1.8 MHz operation. This modification addresses these limitations by integrating a DPDT switch for direct signal bypass, enhancing operational flexibility. Furthermore, the guide details the addition of a T130-2 iron powder toroid, wound with **29 turns** of enamelled copper wire, to augment the tuner's internal inductance. This increases the maximum inductance from approximately 17µH to around **27µH**, enabling effective impedance matching on the _160-meter band_. The modification involves cutting the wire after the 'L' tap on the original inductor and inserting the additional toroid, ensuring the entire original coil plus the new inductance is engaged when 'L' is selected. This preserves the functionality of other inductance settings while extending low-band performance. The article also highlights a potential RF burn hazard from the variable capacitor nuts on the MFJ-971, even at QRP power levels. -

Operating where independent media is suppressed, _Radio Free Europe/Radio Liberty_ (RFE/RL) delivers news and information in 27 languages to audiences in 23 countries. This resource primarily functions as a news portal, focusing on geopolitical events, regional conflicts, and human rights issues, particularly in areas like Ukraine, Russia, Iran, Afghanistan, and Central Asia. It features articles, videos, podcasts, and photo galleries, covering topics such as international relations, energy politics, and the impact of conflict on civilian populations, often highlighting the perspectives of local journalists and freelancers in challenging environments. The content frequently addresses the operational context of shortwave broadcasting, though the site itself is a digital news platform. For example, it details the implications of long-distance strikes and regional military capabilities, which are relevant to understanding the strategic importance of various communication methods. The resource also provides insights into the challenges faced by populations in areas with limited access to uncensored information, underscoring the role of independent news organizations in providing alternative narratives.
