Graham,

There is no single s/n figure or specified BW i= n=20 which to measure it.
WOLF works by building copy up over a period of tim= e,=20 and assuming good
frequency/phase stability, a half hour or more is=20 practical.

The data rate is fairly fast, 10 b/s, with a 960 bit messa= ge,=20 so that a
complete frame of data is sent in 96 seconds. You get three qu= ick=20
reports in the first 96 seconds, and then decodes every 96 seconds=20
after. Each message is 15 characters, with no rules about callsign=20 format.

Tests done some years ago show it roughly equivalent to QRSS6= 0 in=20 terms
of signal level. It does give some clues as to whether a signal ha= s=20 been
locked-in, and has the possibility of partial copy, unlike some "al= l or=20
nothing" modes. Fifteen characters in a half-hour is of course much=20
faster than QRSS60 would permit. 2-way QSO's are fairly easy with some=20=
advance agreement on what to do with the 15 characters.

The downs= ides=20 are the need for a linear transmitter system (as this is
PSK),=20 receiver/transmitter stability and frequency accuracy. It works at
600=20= meters, but is fairly useless at 160 meters and up.

The newest versio= n is=20 by DL4YHF, and may be found at:
http://www.qsl.net/d/dl= 4yhf//wolf/=20 .

Note that this version has 5 b/s and 20 b/s variations. Testing has= =20
shown that the program tends to provide copy in the same amount of time,= =20
so there's no overriding advantage to either.
