# These tests investigate what happens when the wrong model is used for
# decoding. A (1800,1000) LDPC code with 3 check per bit is used.
# Testing is done by transmitting random messages. Decoding is done using
# a maximum of 100 iterations of probability propagation.
#
# The first set of tests compares decoding of messages sent through an
# AWGN channel using the correct AWGN model with sigma=0.90 to decoding
# using AWGN models with incorrect values for sigma and to decoding
# using AWLN models with varying width parameters for the logistic noise
# distribution.
#
# A second set of tests compares decoding of messages sent through an
# AWLN channel using the correct AWLN model with width=0.50 to decoding
# using AWLN models with incorrect values for width and to decoding
# using AWGN models with varying sigma parameters.

_JT65 decoding parameters_
- *Random erasure patterns* logarithmically scales the number of
pseudo-random trials used by the Franke-Taylor JT65 decoder. Larger
numbers give slightly better sensitivity but take longer. For most
purposes a good setting is 6 or 7.
- *Aggressive decoding level* sets the threshold for acceptable
decodes using Deep Search. Higher numbers will display results
with lower confidence levels.
- Check *MSK144 Contest Mode* to cause generation and auto-sequencing
of MSK144 messages with four-character grid locators in place of signal
reports.
- Check *Two-pass decoding* to enable a second decoding pass after
signals producing first-pass decodes have been subtracted from the
received data stream.
_Miscellaneous_
- Set a positive number in *Degrade S/N of .wav file* to add known
amounts of pseudo-random noise to data read from a .wav file. To
ensure that the resulting S/N degradation is close to the requested
number of dB, set *Receiver bandwidth* to your best estimate of the
receiver's effective noise bandwidth.
- Set *Tx delay* to a number larger than the default 0.2 s to create
a larger delay between execution of a command to enable PTT and onset
of Tx audio.
IMPORTANT: For the health of your T/R relays and external
preamplifier, we strongly recommend using a hardware sequencer and
testing to make sure that sequencing is correct.
- Check *x 2 Tone spacing* to generate Tx audio with twice the normal
tone spacing. This feature is intended for use with specialized LF/MF
transmitters that divide the audio waveform by 2 before further
processing.
