[. . . ] This portion of level is applied when audio routing "C" is selected in the Router - Audio Switching tab. Following approach is recommended: a) Select MK RADIO pot to about three o'clock possition. b) Select routing "B" for transmiting from computer (audio goes to rig AF IN) and using windows mixer sliders adjust appropriate (not overdrived) level. c) Select routing "C" for transmiting from computer (audio goes to rig MIC IN) and using trimmer and transceiver MIC GAIN adjust appropriate (not overdrived) level. This approach allow you to use front MK RADIO pot for both routing B and C and have always enough margins when you change bands, modes (compressor ON/OFF) etc . . . without needs to change windows mixer settings or trimmer position. 3. Inside the MK on the top PCB, on the left side, two jumpers are located for selecting integrated preamplifier inserted between attached microphone to RJ45 MIC jack or EXT MIC jack and computer MIC IN input. Turning preamp ON is not neccessary for electret microphones as are used with Icoms radios. Turn this preamplifier ON for Kenwoods and Yeasus original dynamic microphones (also Heil). By default factory settings, this preamplifier is bypassed. 16 microHAM © 2004 All rights reserved 12. USB Device Router MicroHAM USB Device Router (router) is a program that provides configuration tool for MK and software interface to another applications in the form of virtual serial ports. To use the MK with any Windows based logging program (and configure it) it is necessary to have installed its driver and run the router. Set up and Operation Router can handle several devices (micro Keyers or microHAM USB interfaces) simultaneously. Each device has its own tab (page) in the main notebook control. Content of a device page depends on device type. For example, USB interface has a simple page with only several controls that allows to associate the interface with virtual serial port(s). On the other hand, micro Keyer has more complex controls organized in several subpages that allows also to change keyer configuration. Device tab is created when a device is first time detected by router and remains in router even though device is disconnected. Automaticaly generated device name (displayed on tab) can be changed using the menu command "Device/Rename". To remove the page of disconnected device use menu command "Device/Delete". User can specify if router has to be started at system start-up and if it starts minimized. This menu contains also item "RT priority". [. . . ] Again, all these settings can be stored to the MK memory for power up behavior, immediately applied or current setting can be stored to the presets. 22 microHAM © 2004 All rights reserved CW / WinKey In this tab you can configure internal CW keyer based on K1EL WinKey chip. Thanks to Steve, K1EL for the great product. Full WinKey manual is available at http://k1el. tripod. com/wkinfo. html. CW output is wired in parallel with CW output from computer. [. . . ]
