MultiKeyer is a dedicated computer keying program designed for amateur radio operators engaging in specialized operating activities such as Earth-Moon-Earth (EME) and Meteor Scatter, as well as general contest operations. It provides distinct modes for both CW and Phone transmissions, enabling automated message sequencing and playback of pre-recorded audio files. The software's interface shares a similar "look and feel" to the popular WSJT Meteor Scatter/EME program, facilitating ease of use for operators familiar with that platform. For CW operations, MultiKeyer offers an EME Auto mode for sending timed messages crucial for EME and Meteor Scatter, alongside a Contest mode that handles automatic CQ calls and preprogrammed messages. On the Phone side, it features a Sequenced Phone mode for transmitting prerecorded .wav files during Meteor Scatter events and an Auto Phone mode for contest use. The program leverages serial COM ports for CW and PTT signaling, and the soundcard for .wav file playback, with configurable PTT interrupt options. MultiKeyer integrates with TRX-Manager for PTT and CW keying, and can send callsigns for logging. It also supports WSJT-style "callsign.txt" files for lookups and adheres to the SO2R protocol for parallel port connections. Designed for Windows 98 and NT, it generally functions on Windows 95, ME, XP, and 2000, requiring a 133 MHz Pentium-class processor.

RadioQTH's Vanity Calls service provides a utility for US amateur radio operators to locate available vanity callsigns, specifically focusing on the shortest possible options. The system filters through all potential callsigns within a user's license class and presents only those currently unused, with results weighted by either their actual character length or their equivalent length in _Morse code_. This approach assists hams in securing memorable and efficient callsigns for CW operation. The service also lists recently granted vanity callsigns, sorted by prefix, offering insight into current FCC assignments. It clarifies the common misconception that callsigns are granted on a first-come, first-served basis, explaining the random selection process for applications received on the same day. The platform updates frequently, providing current data on available 1x2, 2x1, 2x2, 1x3, and 2x3 callsign formats, which are highly sought after by _Extra Class_ and _Advanced Class_ licensees.

IC706 Specifications by universal radio inc

Applying for an FCC vanity call sign requires navigating the _Universal Licensing System_ (ULS) database to identify available call sign blocks and specific desired combinations. The process involves submitting an online application via the FCC website, ensuring all instructions are meticulously followed to avoid rejection. Typical processing time for a vanity call sign application is approximately **18 days**, after which the ULS database reflects the updated license grant. Operators often seek vanity call signs for various reasons, including aligning with a new license class, desiring a shorter call sign for CW efficiency, or simply preferring a more memorable phonetics. The resource emphasizes self-application to avoid third-party service fees, directing users to verify availability through tools like Vanity HQ. Key steps include selecting a primary call sign and several alternates, ensuring the chosen call sign conforms to FCC rules for the operator's license class. Payment can be made online or via check, with prompt submission critical to prevent application dismissal.
