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 theHELLO 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 thestdout
. To demonstrate the capabilities of the decoder, signal and noise power GUI sliders are provided for easy testing and experimenting.
