APRS Passcode Generator

This lightweight plugin lets ham radio operators calculate their APRS-IS passcode from a callsign. It uses a simple algorithm to compute the passcode locally in the browser using JavaScript, so no data is sent externally.

Features:

• Generates passcode for APRS-IS (used in Xastir, YAAC, etc.)
• Easy to use shortcode: [aprs_passcode]
• Fully client-side (JavaScript only)
• No external API calls or database usage
