System Considerations - microHAM microKEYER II User Manual

TIP: When you start to create your own presets, always begin by selecting the "default" preset. This
will configure the audio levels to the proper state before starting any customization.
22. Select the DVK tab in Router and set the REC MIC slider to the same level as the REC MIC on the
Audio Mixer tab. Set the TX MASTER and WAVE sliders to the same level as the TX
VOICE/DIGITAL sliders on the Audio Mixer tab.
23. Record a message and adjust the REC MIC slightly if necessary so that the REC MIC VU Meter
does not peak into the red.
24. Play back the message and adjust the WAVE slider so that the transceiver ALC meter peaks at the
top of the ALC zone (the same level as steps 9 and 11).
microKEYER II can be used with a wide variety of software. The capabilities of those packages will have
large influence on the level of computing power needed to utilize microKEYER II.
When used with Windows based contest logging applications like CTWin, N1MM Logger, Win-Test, and
WriteLog or Windows based general logging applications like DXBase 2007, DXLab Suite, DX4WIN,
Logger 32 and others, the microHAM control and interface application "microHAM Router" must run along
side the application program. Since both the logging programs 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 will run on slower computers, the minimum tested system is a 450 MHz Pentium III
or Celeron, Windows 2000, 256MB 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. It has not been, and won't be a priority, to make it run on clunkers or discontinued
operating systems.
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 1.6GHz PC
compatible computer with Windows XP Home or higher, 512 MB RAM, CD-ROM, root USB 2.0 port, a
transceiver with supported control protocol and logger, control, or digital mode software.
