Most people see the static between radio stations as empty noise, but for the amateur radio operator, that static is a vast, invisible frontier waiting to be mapped. The thrill of catching a faint signal from halfway across the globe is only surpassed by the professional satisfaction of documenting that contact with surgical precision.

The Philosophy: Mapping the Airwaves

Amateur radio, or "ham" radio, is a hobby built on the intersection of technical skill and social connection. A CQ log is more than a list of numbers; it is a historical record of your station's reach and the atmospheric conditions of the moment. This template moves your logging from a paper notebook—where ink fades and search is impossible—to a digital archive that can be sorted by frequency, location, or signal quality in seconds.

The Blueprint: Signal Architecture

The structure of this log is designed to capture the technical DNA of every transmission.

  • The Spectral Grid: Fields for frequency and modulation are the baseline. Whether you are operating in NFM, AM, or the classic rhythmic pulse of CW (Morse code), you have a dedicated slot for the technical specifics.
  • The Identity Layer: Capturing the callsign and name of the contact is the social core of the hobby. Memento’s text fields allow you to note the qth (location) of the distant station, allowing you to build a geographical map of your transmissions over time.
  • Categorical Classification: The type field allows you to segment your activity. You can distinguish between routine ham contacts, monitoring avia (aviation) bands, or tracking emergency frequencies during a storm.

Usage Scenarios: The DX Contest

You are participating in a long-distance (DX) contest over a weekend. The bands are crowded, and contacts are happening fast. You don't have time for complex data entry. You enter the frequency, tap the modulation (USB), and quickly type the callsign. You hit the on air boolean to confirm the connection. Weeks later, when you receive a physical QSL card in the mail, you use the search function to find that specific date and confirm the contact for your award application.

Power Feature: Rating for Signal Quality

The rating field (1-5) acts as your personal assessment of the contact's clarity. By grouping your library by this rating, you can identify which frequencies and qth locations provide the most reliable signals for your specific antenna setup. It turns a collection of individual logs into a powerful tool for station optimization and antenna tuning.
