The Mobile-Portable Reflector serves as a dedicated discussion platform for amateur radio operators interested in mobile and portable operations. It facilitates the exchange of information and answers questions specifically related to operating amateur radio from vehicles, temporary field locations, or while walking. The platform is not intended for general amateur radio discussions; its scope is strictly limited to mobile-portable topics. Subscribers can access prior postings to review historical conversations and solutions. The list is administered by _dick at k7vc.com_ and operates on Mailman version _2.1.12_. Subscription requires email confirmation and offers optional privacy password protection, with an option to receive daily batched emails.

Presents the VHFDX.EU web cluster, a specialized resource for VHF, UHF, and microwave DX spotting. It details the cluster's functionality, including real-time spot aggregation and a DXCluster Map interface for visualizing activity. The resource highlights its integration with the MMMonVHF backbone, ensuring a robust data flow for monitoring band openings and propagation events across higher frequencies. It also references reviews of the ON4KST and N0UK chat systems, which are frequently used in conjunction with VHF DX operations. The platform offers a mobile-optimized view for on-the-go access to DX spots, catering to portable and mobile operators. It further provides daily ES (Sporadic E) spot summaries, a critical feature for VHF operators tracking this specific propagation mode. The cluster serves as a central point for operators to share and receive information on rare grid squares, contest activity, and general band conditions above 50 MHz.

The ARRL Contest Results Database serves as a centralized repository for official scores and detailed breakdowns from numerous ARRL-sanctioned operating events. This resource typically features comprehensive listings of participants, their submitted logs, and final standings across different categories, modes, and bands. It allows hams to review their performance, compare results with other operators, and analyze contest trends over time, providing valuable insights into competitive amateur radio. Historically, the database has showcased the efforts of thousands of contesters, from single-operator entries to multi-operator, multi-transmitter stations. While the current status indicates scores are not immediately available, the database's primary function is to archive and present the outcomes of events like the ARRL DX Contest, Sweepstakes, and Field Day. This historical data is crucial for tracking individual progress, identifying top performers, and understanding the competitive landscape within the amateur radio community.
