During tests it was determined that this is much more reliable. The theory is that the first packet of a burst was frequently not detected because the squelch opened too late if the channel was very noisy. Unfortunately, the squelch now opens very often even if no signal is present. This will be improved in the future. |

Hamnet70: IP-based Networking on the 70cm Amateur Radio Band
This project seeks to implement a wireless networking system that can transfer Internet Protocol (IP) packets at high speed. In spirit, it is somewhere at the intersection of Packet Radio, Hamnet and Wireless LAN.
Documentation
The documentation is written in AsciiDoc and can be found in the doc directory. It describes the packet formats, used modulation and channel codes, timing and so on.
Implementation
The project is implemented in C and uses the liquid-dsp library for large parts of the signal processing. The whole modulation, synchronization and demodulation process is implemented in software. This allows to use generic SDR hardware to transmit and receive packets. Currently, only the HackRF One is supported.
You can find the code in the impl directory.
