Thanks for replies. I took a look at the archive and it is pretty sparse. But I am pretty committed to using Fedora so thought I'd check in. I use fldigi all the time for digital qso and for logging. So thanks for keeping the pkg in fedora. (Has it been pushed to f24? I need to upgrade one of these days and don't want to break my fldigi.) I'll check out linrad. Tho I am dubious abt hooking my rf up to my soundcard (ie MB). An unfortunate amount of ham related software seems to be mostly built in Windows. And not particularly WINE friendly. But I really do not want to install any MS on any of my machines. Better to do without. Just spent time on NAQCC sprint. Keyer and sharp filter was all the fancy stuff I ended up using. If I have any fun with SDR I'll try to post something abt it. Keith
