The site frequently updates with news, event schedules, and technical information, reflecting an active and engaged amateur radio community.

A 200 kHz bandwidth digital transmission system for image transfer in the Amateur Service is under development, specifically targeting VHF allocations. John B. Stephensen, KD6OZH, leads this project under an FCC Special Temporary Authority (STA) valid until September 10, 2006, authorizing emissions up to 200 kHz bandwidth in the 50.3-50.8 MHz segment. Current regulations typically limit bandwidths to 20 kHz on VHF amateur bands, making this STA crucial for testing wideband digital modes. The modem, a modified **OFDM** (Orthogonal Frequency Division Multiplexed) unit, was initially tested on the 70-cm band. It splits a high-rate data stream into multiple low-rate subcarriers to mitigate multipath echoes. The system uses a DCP-1 card with a Xilinx XC3S400 FPGA and Oki Semiconductor ML67Q5003 microcontroller. The transmitter, located at 36d 46m 30s N, 119d 46m 22s W, generates 150 WPEP into an 8 dBi gain vertical antenna, while the mobile receiver uses a Ham-stick. Three data formats for 50, 100, and 200 kHz channels are being tested, with encoded data rates of 96, 192, and 384 kbps. Verilog code for the VHF OFDM modem is 95% simulated, with modifications from the UHF version including increased filter coefficient precision and a change from Ungerboeck **TCM** to BICM for improved performance over fading paths. Final tests will involve one-way over-the-air measurements of bit error rates and coverage area.

The HA8TKS VHF DXCluster is an essential online resource for amateur radio operators focusing on VHF and higher frequencies. This platform provides real-time information on DX spots, allowing users to track and engage in two-way radio communications effectively. The integrated map mash-up feature enhances the user experience by visually displaying the locations of DX stations, making it easier for operators to plan their contacts and optimize their antenna setups based on geographical data. In addition to the DXCluster functionality, the site offers various HAM tools, including a QRB calculator, which helps operators determine the distance to DX stations based on Maidenhead grid locators. The platform supports multiple modes of operation, including CW, SSB, RTTY, and digital modes like FT8 and JT65. With a user-friendly interface and comprehensive data, the HA8TKS VHF DXCluster is a valuable asset for both novice and experienced operators looking to enhance their DXing and contesting activities.

This resource documents numerous QRP (low power) portable amateur radio operations conducted by W1PID, Jim Cluett, primarily from various outdoor locations in New Hampshire. The content includes detailed accounts, photographs, and operational specifics for over 350 individual "QRP Adventures," often involving hiking, biking, or kayaking to remote sites. Each entry typically highlights the location, date, bands and modes used (frequently CW on HF), and notable DX contacts made with minimal power, sometimes as low as 200mW WSPR. The site serves as a chronicle of practical QRP field operation, demonstrating successful DXing and contesting from challenging environments. It showcases diverse operating scenarios, from mountaintops like Cannon Mountain and Knox Mountain to lakeshores, riverbanks, and even marine mobile operations.

The EA8ALP personal page, hosted on QSL.net, is currently inaccessible, presenting a 404 "Page Cannot Be Found" error. This resource was intended to feature Adelto, an amateur radio operator from the Canary Islands, likely detailing his station, operating activities, or other personal ham radio interests. The QSL.net platform, which hosts over 30,000 amateur radio websites, provides free web and email services to operators and organizations, relying on donations for support. While the specific content of EA8ALP's page is unavailable, the platform's structure suggests it would typically include information relevant to **DXing** and **contesting**, common interests for operators in geographically desirable locations like the Canary Islands. Users encountering this error are advised to contact the website owner directly or use an internet search to locate the intended content, as QSL.net cannot assist with individual site content issues.

The World Radiosport Team Championship (WRTC) is a unique on-site ham radio competition, typically held every four years, bringing together top operators globally. Unlike traditional contests where participants operate from their home QTH, WRTC competitors travel to a designated location and operate from identical stations under field conditions, ensuring a level playing field. Past events have taken place in diverse locations such as Seattle (1990), Slovenia (2000), Russia (2010), and Italy (2023), showcasing the international scope of this **radiosport** challenge. Because each WRTC event is organized by a dedicated, volunteer-driven committee, historical information and results often become dispersed across various online platforms.
