TR4W is a contest logging software package supporting over **180** amateur radio contests. The program operates on Windows 7 to windows 11 operating systems. It supports CW keying via serial port, LPT port, or Winkey, with CW speeds ranging from 1 to **99** WPM. Paddle input via LPT port enables the program to function as a keyer, with paddle input aborting computer-generated CW. PTT support includes programmable delay. The software incorporates automatic super check partial and call checking, along with an expanded .DTA database format for names, QTH, grid, and SS check information. A band map displays color-coded aging data. The software features a built-in telnet DXCluster interface, automatically inserting spots into the band map. It supports RTTY operation via the MMTTY engine and includes WAE QTC support for both European and non-European stations. TR4W provides radio interfacing for Elecraft, Icom, Japan Radio, Kenwood, Ten-Tec, and Yaesu transceivers, utilizing serial or USB-to-serial adapters. Networked multiple-rig operation is supported through a client-server model using TCP/IP protocol. Integrated two-radio support (SO2R) is present. The program includes on-the-fly MP3 recording and log backup to USB drives or selected HDD folders. It uses the standard CTY.DAT file for country and beam heading data.

The PG7V Contest Calendar provides a curated listing of significant **HF contests**, with a particular focus on events relevant to European amateur radio operators. It details contest specifics such as start and end times in UTC, eligible bands (e.g., 80 meters, 40 meters, 10 meters), and required exchange information (e.g., serial number, CQ-zone, DOK, locator, age). The calendar includes diverse modes like CW, SSB, PSK63, RTTY, and FT4, catering to various operating preferences. Featured contests include the RSGB 80m Club Championship, WW WPX Contest, IARU Region 1 Fieldday, and ARRL International Digital Contest. Each entry links directly to the official contest rules for detailed information. The calendar also notes specific participation rules, such as the 1 KHz QSY requirement in the HA3NS Memorial Contest or the 24-hour single-operator time limit in the ARRL International Digital Contest. This resource is updated regularly, ensuring timely information for upcoming **contest operations** over a four-week period. It serves as a practical tool for hams planning their contest activity.

When planning your operating schedule, a reliable contest calendar is an essential tool for any serious contester. This DARC-maintained resource compiles current contest announcements for both HF and VHF/UHF operations, making it straightforward to identify upcoming opportunities for competitive radio sport. My own experience has shown that having a centralized, well-organized calendar saves significant time, especially when targeting specific events like the Clubmeisterschaft Classic (CMC) or the KW-Pokal. The DARC calendar highlights these German and European scoring contests in yellow, providing immediate visual cues for participants. HF contests are clearly marked in blue, while VHF/UHF events appear in red, simplifying band-specific planning. Beyond the major international contests, the calendar emphasizes regional events, which can be particularly useful for those aiming to improve their standing in local club competitions or explore less common contest formats. Special activity periods, such as those spanning multiple days, are also noted with a green background, ensuring operators are aware of extended operating windows.
