APRS Passcode Generator

by pd2hsb

Description

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

Installation

Upload the plugin files to the /wp-content/plugins/aprs-passcode directory, or install the plugin via the WordPress plugin screen directly.
Activate the plugin through the ‘Plugins’ screen in WordPress.
Use the shortcode [aprs_passcode] in any post or page to display the generator.

Faq

Is this plugin secure?

Yes. The callsign never leaves the browser. The passcode is calculated locally using JavaScript.

Can this be used to log into APRS-IS servers?

Yes, this plugin generates the same passcode used by most APRS software clients. However, you still need valid credentials and must follow APRS-IS network rules.
