CQRLOG is an advanced ham radio logging application based
on a MySQL database. It provides radio interfacing utilizing the hamlib libraries
(currently support for 140+ radio types and models), DX cluster
connection, band map, QRZ.com/HamQTH.com callbook (XML access),
ClubLog and Logbook of the World support, IOTA support, a
grayliner, propagation indicator, xplanet support (maps in azimuthal projection centered in
your QTH), OK1RR free QSL manager database etc.
CQRLOG is intended mainly for seriously HF DX minded operators
but can be used for any ham logging purpose, also by casual operators.
It is equipped with probably most accurate DXCC country database
available, providing not only the country resolution but also state,
province, region, district etc. It resolves also antarctic bases,
special event stations, contest callsigns and much more.
CQRLOG has its own web site at
Find news, changes, latest additional files and howtos there.

The Radio Control interface is provided using hamlib
a set of libraries, which is a development effort to provide a
consistent interface for programmers wanting to incorporate radio
control in their programs. hamlib
is not a complete user
application, rather, it is a software layer intended to make
controlling various radios and other shack hardware much easier.
Most recent amateur radio transceivers allow external control
of their functions through a serial interface. Unfortunately, control
commands are not always consistent across a manufacturer's product line
and each manufacturer's product line differs greatly from its
There's no standardized protocol to remotely control one's
rig, be it a Ham radio transceiver, a SWL receiver, any kind of scanner
or other mobiles. However, many manufacturer have designed their
own proprietary protocol, implemented in some of their product family.
Therefore, each rig family will require a hamlib
backend to set
the VFO frequency, change mode and passband width, get current signal
strength, etc. The actual list of supported radios can be found on Hamlib website
Ubuntu users can use a repository on Launchpad
. To add the repo, open a terminal and copy&paste
sudo add-apt-repository ppa:ok2cqr/ppa
sudo apt-get update
sudo apt-get install cqrlog
Only Ubuntu 14.04 and Ubuntu 16.04 are officially supported but there are also builds for other
versions of Ubuntu on Launchpad
Debian users can simply install using the package manager
sudo apt-get install cqrlog
For other distributions, you can use binaries located at
Some of them, like Fedora and Arch, have their own repositories for CQRLOG - Fedora: https://apps.fedoraproject.org/packages/cqrlog
If upgrading, no important file will be overwritten. Anyway, backup your log
before you begin any
- HamLib - must be installed even if you don't want radio control. The sources are available
at http://hamlib.sourceforge.net/, however
precompiled packages are available for almost all major Linux distributions.
- MySQL server and client - The MySQL client must be installed,
without this the program will not work at all. A MySQL server must be reachable,
either on the local machine or via a network.
- libssl-devel needed if you want to use LoTW and/or online log upload
