This webpage allows you to create custom QSL cards (confirmation of radio contact) as PDFs for printing. You can personalize them with images and information. The cards are standard size (5.5" x 3.5") but can be adjusted slightly for easier printing on regular paper. You'll need Adobe Acrobat Reader to view the PDFs. There's also an option to create a free account to save your information for future cards.

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 California QSO Party (CQP) is the premier state QSO party held every year on the first weekend of October. The Northern California Contest Club (NCCC) has sponsored CQP since 1974.

The **HamRacer** voice keyer, a Windows-based application, is showcased in this video, illustrating its utility for radio amateurs participating in SSB contests. It functions as a synthesized PC-based voice keyer, specifically designed for HF and VHF SSB contest operations, allowing operators to transmit pre-recorded or text-to-speech generated messages during rapid-fire exchanges. The demonstration includes actual recorded QSO examples from a contest, featuring contacts with stations such as SP6OWA, S57O, OK1IEI, 9A1DL, OE1PAB, OK1GTH, and 9A1E. These examples highlight the software's practical application in a live contesting environment, demonstrating how it facilitates contest participation for operators who might otherwise face challenges with traditional voice keying. The resource provides a direct look at the software in action, emphasizing its role in promoting inclusivity within the amateur radio contesting community. It details the use of Windows SAPI for speech synthesis, a core component of HamRacer's functionality.

The Club Radio Amateur de Québec (CRAQ) is a prominent amateur radio club based in Québec, Canada, dedicated to fostering interest and participation in amateur radio. It provides a platform for local hams to connect, share knowledge, and engage in various radio-related activities, including **DXing**, contesting, and technical experimentation. The club supports its members through regular meetings, technical presentations, and organized operating events, aiming to enhance their skills and enjoyment of the hobby. CRAQ also plays a role in public service communications, often collaborating with local authorities for emergency preparedness and response. CRAQ's activities include operating club stations, organizing **field day** events, and offering training sessions for new licensees. Members frequently participate in provincial and national contests, contributing to the club's competitive standing.
