System Considerations

CW Keyer can be used with a wide variety of application packages. The capabilities of those packages will
have significant impact on the level of computing power needed to utilize CW Keyer.
When used with Windows based contest logging applications like N1MM Logger Plus, Win-Test, and
WriteLog or Windows based general logging applications like DXBase, DXLab Suite, DX4Win, Logger 32
and others, the microHAM control and interface application "microHAM Router" must run with the
application. Since both the logging program and microHAM Router are real-time applications, system
performance will be dependent on both CPU speed and the amount of available RAM.
While microHAM Router may run on slower computers, the minimum tested system is a 1.8 GHz Core2Duo
processor, Windows 7, 1 GB RAM, CD-ROM, and USB 1.1 port. Whether Router can run as designed on
slower machines with less memory and leave enough resources for application programs has not been
determined. microHAM Router is not supported on any 16 bit version of Windows (95, 98, ME, SE).
In order to provide sufficient performance for simultaneous operation of microHAM Router, a logging
application, Internet connectivity and other accessory programs, the recommended system is a 2 GHz or
faster multi-core CPU with Windows 8.1 or later, 4 GB RAM, CD-ROM, root USB 2.0 port, and a transceiver
with supported control protocol and logger, control, or digital mode software.
