_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 *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 *FT8 and MSK144: NA VHF Contest Mode* to enable generation and
auto-sequencing of messages using four-character grid locators in
place of signal reports, as required for most North American VHF
contests.
- 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.

// UDPDaemon - an example console application that utilizes the WSJT-X
// messaging facility
//
// This application is only provided as a simple console application
// example to demonstrate the WSJT-X messaging facility. It allows
// the user to set the server details either as a unicast UDP server
// or, if a multicast group address is provided, as a multicast
// server. The benefit of the multicast server is that multiple
// servers can be active at once each receiving all WSJT-X broadcast
// messages and each able to respond to individual WSJT_X clients. To
// utilize the multicast group features each WSJT-X client must set
// the same multicast group address as the UDP server address for
// example 239.255.0.0 for a site local multicast group.
