The most common problems are radio control related and seems mostly to be a hamlib issue. I noticed that hamlib issues reporting mostly Ubuntu users. Hamlib is an awesome piece of software providing support of > 150 different types of radios, transceivers and rotators which is a heroic effort, isn't? The idea that the developers are supplied with every brand new type of radio is totally false, they must find a Linux user who is an owner of particular radio(s) and is willing to contribute, at least with testing and bug reporting.
we are pleased to develop the program and share our experience with you. You are helping a lot with your input (comments, suggestions and bug reports). Like any other software, there are lots of questions appearing again and again, regardless of the detailed help and many previous comments. Unlike others, we are not intended to say the usual RTFM (Read The Fantastic Manual) but to reply with a particular solution tailored to your situation.
There are some complaints concerning lack of eQSL.cc support. To my best knowledge, CQRLOG can be used with eQSL.cc, however it seems a bit risky to introduce another option which will be considered as 'confirmed'. Now, the confirmation methods uses 'Q' for contacts confirmed with usual paper QSL and 'L' for LoTW confirmations. There is also possible to choose 'Confirmed only' stats for the usual (paper) way, 'LoTW only' for contacts confirmed exclusively via LoTW and both methods together.
