Hi all,  I saw the spectrum plot Alberto provided of Valerio's wolf
transmission. What an ugly sight.    It takes between 15 and 20 Hz of
specytum space.
        With 30 sec dots I can receive and separate a station every 250
millihertz.  In other words In the space of one wolf transmission  60 to
80 QRSS stations could be trying to have QSOs.   I do not doubt the fact
that the wolf experiments are worthwhile from a testing of technology
point of view.  I feel, however, that wolf as currently configured is
not a worthwhile mode for general amateur operation in the small 136kHz
band.  I especially resent the attitude of VA3LK that he would transmit
regardless of potential QRM to others as stated in one of his emails.
       Current transmissions above 137.5 kHz will not cause much
trouble.  As interest in the band grows and more  countries get on the
band,  We will have to very carefully choose modes of operation which
provide the best combination of bandwidth consumed compared with
communication efficiency, coupled with ease of use.   So far I vote for
DFCW and QRSS.  I  looked last night but saw nil.
