Instant Callsign Intelligence Over APRS

Finding accurate callsign information during on-air operations shouldn’t require a web browser or database lookup. 9M2PJU-6 APRS Malaysia Callsign Bot brings real-time Malaysian callsign intelligence directly onto the APRS network, accessible from any APRS-capable radio or client.

Built specifically for the Malaysia amateur radio community, this APRS bot delivers fast, reliable callsign lookups—entirely over APRS messaging.

What Is the 9M2PJU-6 Callsign Bot?

9M2PJU-6 is an APRS-IS–connected service station that listens for APRS messages and responds with official Malaysian amateur radio callsign details, including:

• Operator name
• License expiry date

The bot also transmits a periodic APRS beacon, ensuring it remains visible and reachable on the network at all times.

No apps. No websites. Just APRS.

Built for Speed and Reliability

Speed matters on-air.

The bot uses a preloaded, in-memory callsign database containing 10,000+ Malaysian callsigns, enabling:

• Near-instant responses
• Zero external lookup delays
• Consistent performance during peak usage

Every lookup is processed locally, ensuring predictable and reliable replies.
