Compiles a detailed calendar of RTTY contests, providing essential information for digital mode enthusiasts. It lists contest dates, links to official rules, and often includes historical results and records, enabling operators to plan their contesting schedule and review past performances. The resource covers a wide array of RTTY events, from major international contests like the _ARRL RTTY Roundup_ and _CQ WW RTTY_ to smaller, regional competitions. Operators can quickly identify upcoming RTTY contests, review specific rules for each event, and access historical data to gauge competition levels. For example, the site details the _BARTG RTTY Sprint_ and the _SARTG New Years_ contest, offering a centralized hub for RTTY contesting information. This resource is particularly useful for those aiming to improve their digital contesting skills or track their progress against established **records**.

TACLog offers a distinct approach to contest logging for **VHF/UHF/SHF** operations, diverging from the rigid input formats often found in other logging applications. This software prioritizes operational freedom, allowing contesters to input data in a sequence that suits their workflow during a fast-paced event, rather than being constrained by predefined field orders. It's particularly tailored for those participating in contests governed by **Region 1 rules**, ensuring compliance with established regulations. The program's design focuses on practicality for serious contesters, providing a robust platform for managing contacts. Its support for the EDI format is a significant advantage, streamlining the process of submitting logs to contest committees and facilitating data exchange within the amateur radio community. My experience with various logging tools confirms that flexibility in data entry can dramatically improve efficiency during multi-operator or high-rate single-operator contests, where every second counts.

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.

This document serves as a reference guide for pilots interpreting the symbols used on Instrument Flight Rules (IFR) Enroute Low and High Altitude Charts for both the United States and Alaska. It focuses on six key categories of information critical for safe IFR navigation and it includes a section dedicated to Oceanic Route Charts for the North Atlantic and North Pacific regions.

Outlines the essential steps for successfully activating a **Summits on the Air (SOTA)** peak, providing a structured approach for amateur radio operators participating in this popular award program. It details crucial pre-activation planning, including navigating the SOTA website, setting up a SOTA Data account, and consulting the **Association Reference Manual (ARM)** for specific regional rules and peak information. The guide also covers using mapping resources like adventureradio.de and lists ofjohn.com to identify suitable summits and check access conditions. The document emphasizes safety during the activation, advising operators to monitor weather, carry rain gear, and plan ample time for the ascent and descent. It specifies the **4-QSO minimum** requirement within the Activation Zone and recommends calling "CQ SOTA" on traditional QRP or VHF calling frequencies. The guide also suggests using local 2m FM repeaters for safety communications and spotting, while clarifying that repeater QSOs do not count for SOTA points. Post-activation activities include submitting logs to sotadata.org.uk, uploading trip reports to share experiences with future activators, and promoting SOTA participation on various reflectors. The guide highlights the program's appeal through its awards system for both activators and chasers, encouraging new participants in North America.
