So far, I have been unable to use the current issue of Fldigi. Everything seems to work except the waterfall image. Also, I have a consistent beat, beat, beat sound, like a clock ticking seconds. I can't get rid of that. I have used Older versions of Fldigi, which I can no longer locate, and I have used the version loaded with Puppy. Are these problems unique to my machine? I'll appreciate any suggestions. Donald Corley, WA5KTX
