Page 4: Important Warnings
© 2010 All rights reserved 2 - IMPORTANT WARNINGS If you power micro KEYER from an external power supply, ALWAYS check the polarity of the 13.8 V power supply. If you use micro KEYER with more than one transceiver, ALWAYS be sure the proper microphone is connected to the RJ45 jack BEFORE connecting the DB37 RADIO cable. -

PTT. With an external PS/2 style keyboard MK also provides keyboard generated CW and RTTY. If a Windows PC running the "microHAM USB Device Router" program is connected, MK also functions as a computer interface. It transfers all digital and analog signals generated by computer applications between the computer and transceiver. -

Page 11: Configuring Microham Usb Device Router
To configure and use microKEYER with Windows compatible application programs it is necessary to have installed the USB driver, started the Router, and applied power to microKEYER (turn on the radio). Router must then be configured to match the requirements of the application (logger or digital mode) software. -
Page 12: Creating And Using Virtual Serial Ports
© 2010 All rights reserved Creating and Using Virtual Serial Ports microHAM Router provides a set of virtual serial ports which allow Windows applications (loggers and digital software) to work with microKEYER just as they would work with "real" (hardware) serial ports. -

(Not used with microKEYER) Options | DVK: Voice message time limit: maximum time for each voice message up to 120 seconds. -
Page 14: Menu: Preset
Each preset contains the settings for all devices connected to, and controlled by, Router. For example, if Router controls a microKEYER, a CW Keyer and a USB Interface, each preset remembers the settings for all devices including the assignment of COM ports and the contents of all sub-tabs except the FSK/CW Messages and DVK tabs. -

TIP: When you upgrade Router, the upgrade will include the latest firmware file. The new firmware will be automatically uploaded to microKEYER when the new version of Router connects for the first time, you have just to allow the upgrade when prompted. -
Page 17: Menu: Help
There are seven (7) tabs for configuring microKEYER. Each tab controls part of microKEYER's functions. Except for the CW/FSK Messages tab, any change is applied immediately to microKEYER. Changes in the Messages are only applied in response to the Store or Store All buttons. -
Page 18: Ports Tab
© 2010 All rights reserved PORTS TAB The virtual ports must be associated with a specific function or device channel (e.g., radio control, CW, PTT, etc.). These assignments should match that of the application. Ports should be assigned first in Router then in the application (e.g., logging or digital mode program). -
Page 19: Nd Cat
© 2010 All rights reserved CAT PORT & 2 CAT PORT The CAT channel is used by the application software to control transceiver frequency, mode, T/R switching and many other parameters. The application communicates with the radio using a serial protocol. Although most modern radios implement some form of serial control, nearly every radio implementation is different. - Page 20 Tracking: This function allows an external receiver to track the transceiver attached to the microKEYER . NOTE: The transceiver attached to microKEYER must be properly interfaced and CAT must be functioning properly. Tracking does not work for “no radio” choices.
- Page 21 Icom), split mode must be initiated and ended by only one application and manual split control (from the front panel of the radio) should not be used. NOTE: Despite extensive testing using various combinations of applications for the CAT and 2 CAT ports, microHAM cannot guarantee proper operation with every potential combination of applications.

"right channel" for its audio source and should be configured to use the 2 FSK port for its FSK output. NOTE: microKEYER supports only one audio channel. There is no connection between the audio output from the second receiver and the sound card. To decode audio from the second receiver, it is necessary to build a small audio isolation network (transformer) and use custom audio connections. -

© 2010 All rights reserved WinKey PORT WinKey is a unique external CW processor developed by Steve Elliot, K1EL. This CW processor supports paddle input like any other electronic keyer, offers many configuration options, and in addition converts ASCII data from the computer to Morse characters. This unique property assures perfectly timed CW output from the computer regardless of OS load. -
Page 26: Audio Switching Tab
© 2010 All rights reserved AUDIO SWITCHING TAB microKEYER allows customizing the audio configuration to meet the needs of a specific logging program or operating style (VOX, foot switch, computer generated transmit/receive switching, etc.) for each operating mode. Router recognizes four operating modes for the radio: CW, VOICE, DIGITAL and FSK. There are separate configurations for routing audio among the microphone, sound card and transceiver inputs for CW, Voice and FSK/DIGITAL. - Page 27 © 2010 All rights reserved 2. The transceiver is switched to transmit by PTT on virtual serial port or by WinKey generated PTT. This setting is displayed in the MIDDLE picture and indicated by the second letter in settings scheme (ACA).
- Page 28 © 2010 All rights reserved Audio Switching Router generally selects the proper audio configuration based on the mode, and optionally frequency, reported by the transceiver in response to polling by the application (logger) and/or Router. If Router is not able to read the operating mode from your radio (radio does not have computer control port or does not report usable mode information), you can select one of four fixed “no radio”...

It is absolutely important to prevent ground currents from flowing to the common ground point by way of the signal cable. If you use a microHAM "keyer," a good test is to remove the DB15/DB37 connector and USB cable from the keyer and measure the resistance from the shell of the DB15/DB37 to the shell of the USB cable. -
