Pulling my hair out. Nothing online has helped. I am NOT a Linux expert. I have installed Linux on this machine a few years ago, and removed it. I have since reinstalled. I am trying to get FLDIGI to run my Icom 7300. I have it working perfectly through Windows. Linux, however, absolutely will not talk to the radio. I have done the "dialout" thing, but I am totally confused about what that is. First time I tried to do it, I was told that it had already been added -- but I don't remember ever doing that, unless I added it under a different version of Linux 2 years ago? I stupidly chose a basic name for my Linux username install, and I wonder if someone else somewhere had added that to dialup, so that's why it does not work for me? I just get 0 rig control at all. Sound card seems to work fine on Rx into FLDIGI, otherwise. It won't transmit. The numbers on the rig and FLDIGI differ. Completely clueless here. I have tried the rig description file for the 7300. I have tried Rigcat and have it set up per online instructions. I have tried Hamlib, and that does nothing. HELP.
