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.

A 500-watt mobile antenna project details the conversion of an old 10m hamstick into a highly efficient, multiband "bugstick" for HF operation. The core modification involves replacing the original coil with 25 turns of 6 turns-per-inch, 1.5-inch diameter coil stock, fabricated from #14 wire. This design, intended for a 3-magnet mount on a vehicle cab, achieves resonance on multiple bands by shorting out specific turns on the coil, similar to a **bugcatcher** antenna. Measurements taken with an MFJ-259 analyzer on a GMC pickup show 0 turns shorted for 20 meters (14.2 MHz), 10 turns for 17 meters, 16 turns for 15 meters, 19 turns for 12 meters, and 23 turns for 10 meters. The construction emphasizes using UV-resistant tie-wraps and #14 solid wire with crimp lugs for robust RF connections, bypassing the fiberglass rod for current flow. A bonus section details a 40-meter version, utilizing 48 turns of 8 TPI, 2-inch diameter coil stock.
