WOLF ... good idea!
 
My TX antenna has been pushed = up again=20 tonight, and I intend to howl for a couple of hours,=20 starting 23:00 UT at 10 b/s speed. 
 
As CFH is still sitting smack in the = middle of the=20 band, I'll move close to the lower edge, squeezing into=20 a narrow HGA-sidebands gap on 135975 Hz (that is unless=20 you may have other suggestions).

Graham,

There is no single s/n figure or specified = BW in=20 which to measure it.
WOLF works by building copy up over a period of = time,=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 = message,=20 so that a
complete frame of data is sent in 96 seconds. You get = three quick=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 = QRSS60 in=20 terms
of signal level. It does give some clues as to whether a = signal has=20 been
locked-in, and has the possibility of partial copy, unlike some = "all 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 = downsides=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 = version is=20 by DL4YHF, and may be found at:
http://www.qsl.net/d/dl4yhf//= 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.
