Well,

I just caught the following fragment, but mostly it's garbage. I've got a
large standing carrier near 503.5 (coming from my ADSL modem!) and that may be affecting things. I can see the lines on the waterfall display during QSB
peaks.

Thanks for that John,

Thats quite usefull , looks to be better than the psk31 , how much of the
'qsb' cycle is it printing  ?

As a rough guess , thats  2 mins of text , which I think is over the qsb
period -60/90 seconds ? , in which case the mode is quite effective on this
band ,
only problem is , it transmitts tones in pairs and needs a linea system .

Tnx

Graham .
