This is currently a demonstration interface. Real APRS-IS connectivity requires server-side implementation with proper rate limiting and regulatory compliance.
🇮🇳 India (VU) Specific Requirements:
- • Valid VU2/VU3 amateur radio license required
- • APRS 144.390 MHz, Bengaluru / Karnataka — listed by the Indian Institute of Hams in its circular of 14 June 2026 as the APRS simplex frequency covering Greater Bengaluru
- • APRS 144.630 MHz, Maharashtra — cited by hobby operators in Maharashtra
- • The WPC has not assigned an APRS channel. Both frequencies are cited by hobby operators in their own areas rather than allocated by any authority, so check locally before operating somewhere new.
- • Follow WPC/ARSI regulations - no encryption, no commercial use
- • Licensed control operator must supervise automated stations
📡 Technical Limitations:
- • RF delivery depends on bidirectional IGates in your area
- • 67-character message limit (APRS protocol)
- • Rate limiting required (~30-second dupe window)
- • Messages may not reach RF users without TX-capable IGates

🔧 Technical Notes

💡 For Production Implementation:
A real APRS chat system requires server-side APRS-IS connection with proper authentication, rate limiting, message queuing, and retry logic. Consider using established APRS software like Direwolf, APRX, or Xastir for reliable operation.
