_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.
|
2016-09-08 18:53:48 +00:00
|
|
|
|
|
|
|
- *Aggressive decoding level* sets the threshold for acceptable
|
2016-09-08 19:03:29 +00:00
|
|
|
decodes using Deep Search. Higher numbers will display results
|
|
|
|
with lower confidence levels.

|
|
|
|
2016-09-08 19:03:29 +00:00
|
|
|
- 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_
|
|
|
|
|
2016-09-08 19:03:29 +00:00
|
|
|
- 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.
|
2016-09-08 18:53:48 +00:00
|
|
|
|
|
|
|
- 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.
