Manolis Surligas 0e0a3e0c08 Finish the AX.25 decoder and add a UDP message source block
The AX.25 decoder is now decoding the received frames.
Also, the module now provides a UDP message source block. This block
will be responsible to receive UDP packets and transform them into PMT
messages for further processing in the GNU Radio flowgraph. As the
communication with the satnogs-client will be done in the same host, we
do not have to care about packet loss.

Furthermore, the module now provides and a debug message  source block
for easy debugging.

Examples

This directory contains a set of useful examples and flowgraphs for testing and demonstrating the performance of the different components of this OOT module

Files

  • morse_ref.wav : This is a reference file containing the HELLO WORLD message. The file is sampled at 8 KHz and the audio frequency is 700 Hz. The Morse code Words per Minute (WPM) is about 20.

Flowgraphs

  • test_matched_filter.grc: Demonstrates the performance of the implemented matched filter for CW decoding.

  • morse_decoding_flowgraph.grc: This flowgraph decodes a CW signal and prints the corresponding message at the stdout. To demonstrate the capabilities of the decoder, signal and noise power GUI sliders are provided for easy testing and experimenting.
