I am one of the developers of QtRadio which is a software defined radio programme able to interface with many of the popular SDR's like Softrock, HPSDR, Perseus etc. and it runs under Linux. To set the radio to interface with CQRLOG, set your preferences/TRX control as follows ...
Radio one/two desc: as you prefer (I use QtRadio)
Device: to 127.0.0.1:19090
RIG ID model: to 2
Poll Rate: to 500
To operate a software defined radio with its spectrum view and frequency versatility coupled with an excellent logging program is a huge operating convenience and advantage.
