[. . . ] 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. 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. Check it only if you experience that your logging program does not correctly pass the CW signal. After adjusting all the settings use the router minimized to system tray. Virtual serial ports First of all it is necessary to create several virtual serial ports (COM) because this is the only way how the applications (logging or control softwares) can access microHAM devices. One or two COM ports will be enough for one microHAM USB interface. [. . . ] If not checked, PTT will not be applied until PTT from computer or WinKey will not be released. Restore CW = if checked state of CW from computer will be copied to the CW output according to its settings. If not checked it will be not applied until PTT from the computer will not be released. Restore FSK = if checked state of FSK from computer will be copied to the FSK output according to its settings. [. . . ]
