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. -
ax25_example.grc
: This flowgraph semonstrates the AX.25 encoder and decoder. It has two different AX.25 payload source blocks. The first one is theDebug Message Source
block that assigns as payload a predefined message, whereas the second one is aUDP Message Source
block that receives the AX.25 payload from a UDP packet.
