Having a problem with CubicSDR in linux, and I'm not sure if the problem is with software functionality or with what is sitting between the keyboard and the back of the chair. Here's what I have: IC-7410 with IF tap to HupRF PAT70M installed. RTL-SDR2832U Panadapter CubicSDR Before getting too far, everything works as expected in Windows using HDSDR, so I know that there is no hardware problem. In Linux (both Fedora 30 and Ubuntu 18.04.03 Bionic Beaver), however, I am using CubicSDR. Since my goal was to reduce/eliminate my dependency on Windoze I'd like to continue using it if I can get things working. Here are my problems: First, LSB and USB appear to be backwards. If I want to listen to traffic using LSB, I have to tune to USB in CubicSDR in order to do so. For traffic using USB, I have to use LSB in the software. I 'could' live with that if I absolutely had to. However, the main problem is with rig control and tuning. In both Ubuntu and Fedora I can tune into an audio stream in the waterfall. If CubicSDR is controlling the rig, and when I click on a stream, the tuner on the rig changes to the frequency I clicked on and the whole band in CubicSDR shifts along with it, at which time the stream I clicked on moves as well. If Rig control is not enabled and I use the audio-out on the laptop, everything is fine. It appears that there is some kind of setting or offset that I need to configure, but I have not been able to figure it out. Is this a problem with the CubicSDR software, or is there something I am simply doing wrong?
