Lage collection of 6 Meters and 2 meters QSOs, recorded in real audio format by OE3MWS

Presents a dedicated online callbook for Romanian amateur radio operators, compiling an extensive database of YO callsigns. It details information sourced from the _Agentia Nationala de Comunicatii_ (ANCOM) and user submissions, including callsigns, names, postal addresses, email contacts, and even photographs. The resource currently lists **10,768** YO callsigns, with **4,987** authorized by ANCOM, offering a centralized lookup for the Romanian amateur radio community. This platform also includes special event callsigns like _YR8D_, acknowledging their importance for QSL information sought by international DXers. It provides categorized lists of YO hams by county, a section for SWLs (radioamatori receptori), and a directory of YO radio clubs and associations. Users can submit updates or corrections via an online form, with validation typically processed quickly, often within minutes, ensuring the database remains current.

The _Egyptian Amateurs Radio Association (E-ARA)_ provides a directory of its members, detailing callsigns such as SU1AL and SU1ER, along with their full names and QSL routing instructions. Each entry typically includes a postal box or street address in cities like Giza, Cairo, and Port Said, facilitating direct QSL card exchange. Specific entries indicate QSL via home call for operators like SU1BH (A71BH) and SU1DZ (9K2DZ), while others, such as SU1MR and SU1SR, route QSLs through SU1ER. The list also contains details for operators with international home calls, including SU2RS, who QSLs via OE6EEG. This resource serves as a basic callbook for the Egyptian amateur radio community, offering essential contact information for local and international hams seeking to confirm contacts or establish communication.

Shortwave listeners and amateur radio operators interested in _numbers stations_ can engage with this mailing list, which serves as a platform for discussing the enigmatic transmissions. The resource facilitates the exchange of information regarding these unusual broadcasts, often associated with intelligence agencies, by allowing members to share observations, decode attempts, and theories. It provides a community space for those who monitor the HF spectrum for these unique, often automated, voice or digital signals. Participation on the list enables members to contribute to a collective understanding of numbers station activity, including changes in frequencies, broadcast schedules, and message formats. While specific technical analysis or signal processing techniques are discussed by members, the primary function is information sharing. The list is administered by csmolinski at blackcatsystems.com, and prior postings are archived for reference, allowing new members to review historical discussions and data.
