|
== NAME
|
|
|
|
wsprd - is a decoder for K1JT's Weak Signal Propagation Reporter (WSPR) mode.
|
|
|
|
== SYNOPSIS
|
|
|
|
*wsprd* ['OPTIONS'] ['FILE']
|
|
|
|
== DESCRIPTION
|
|
|
|
*wsprd* - The program is written in C and is a command-line program that reads
|
|
from a .c2 FILE or .wav FILE and writes output to the console. It is used by
|
|
WSJT-X for wspr-mode decoding.
|
|
|
|
|
|
== OPTIONS
|
|
*-a <path>*:: Path to writeable data files, default="."
|
|
|
|
*-c <file>*:: Write .c2 file at the end of the first pass
|
|
|
|
*-e x*:: x is transceiver dial frequency error in Hz
|
|
|
|
*-f x*:: x is transceiver dial frequency in MHz
|
|
|
|
*-H* :: do not use, or update the hash table
|
|
|
|
*-m* :: decode wspr-15 .wav file
|
|
|
|
*-q* :: quick mode - does not dig deep for weak signals
|
|
|
|
*-s* :: single pass mode, no subtraction (same as original wsprd)
|
|
|
|
*-v* :: verbose mode, shows duplicate decodings
|
|
|
|
*-w* :: wideband mode - decode signals within {plus}/- 150 Hz of center
|
|
|
|
*-z x*:: x is fano metric table bias, default is 0.42
|
|
|
|
The FILE can be either .wav or .c2, for example:
|
|
|
|
-----
|
|
./wsprd -wf 14.0956 140709_2258.wav
|
|
-----
|
|
|
|
*NOTE* for .c2 files, the frequency within the file overrides the command
|
|
line value.
|
|
|
|
== FEATURES
|
|
* By default, *wsprd* reports signals that are within {plus}/- 110 Hz of the
|
|
subband center frequency. The wideband option (-w) extends this to {plus}/- 150 Hz.
|
|
|
|
* *wsprd* maintains a hashtable and will decode all three types of wspr
|
|
messages. An option (-H) is available to turn off use of the hashtable.
|
|
|
|
* The symbols are decoded using Phil Karn's sequential decoder routine, fano.c
|
|
|
|
== NOTES
|
|
. This program attempts to maximize the number of successful decodes per transmit
|
|
interval by trying to decode virtually every peak in the averaged spectrum.
|
|
The program also implements two-pass decoding, whereby signals that are successfully
|
|
decoded are subtracted one-by-one during the first decoding pass. Then, the
|
|
decoder is run again. In many cases the subtraction process will uncover signals
|
|
that can then be successfully decoded on the second pass.
|
|
|
|
. There will be occasional duplicate decodes when two closely spaced
|
|
peaks come from the same signal. The program removes dupes based on callsign
|
|
and frequency. Two decodes that have the same callsign and estimated frequencies
|
|
that are within 1 Hz will be treated as decodes of the same signal. This
|
|
dupechecking is turned off with the -v flag.
