NEW: M17 Bridge - Protocol Conversion between M17 and AX.25

A GNU Radio module for bridging between M17 digital radio and AX.25 packet radio protocols.

Features

Protocol Support

• M17 Digital Radio: Complete M17 protocol support with audio encoding and data packets
• AX.25 Packet Radio: Full AX.25 support for I, S, and U frame types with KISS TNC interface
• APRS Integration: Position reporting and messaging support
• FX.25 FEC: Forward Error Correction for noisy channels
• IL2P Protocol: Modern replacement for AX.25 with data whitening for error correction optimization

Bridge Capabilities

• M17 ↔ AX.25 Conversion: Seamless protocol translation
• Callsign Mapping: Automatic address translation between protocols
• Mode Switching: Dynamic protocol selection
• Data Format Conversion: Automatic payload adaptation

Error Correction Features

• FX.25 FEC: Forward Error Correction for noisy channels
• IL2P Protocol: Modern replacement for AX.25 with data whitening for error correction optimization with improved reliability
• Frame Validation: Automatic frame integrity checking
• Retry Mechanisms: Automatic retransmission for failed frames
