An advanced ham radio logger based on Firebird database. Provides radio control based on hamlib libraries (currently support of 140+ radio types and models), DX cluster connection, QRZ callbook (web version), a grayliner, QSL manager database etc.
CQRlog is the logger I was waiting for on Linux. As it has matured my motivation to really integrate with LoTW and now eQSL kicked into high gear. This program is well worth a look and then getting to know well.
