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. 73 de John VE1ZJ
