8. PRINCIPLE OF OPERATION
micro KEYER ("MK") is a all mode interface between computer and transceiver.
Computer sound card is connected to MK usingthree (3) standard audio cables and USB port USB A-B
cable. All these cables are included to the MK pack.
Transceiver and MK is connected bysingle radio cable terminated on one side byDB37Mand on the other
side byvarious plugs dependingon the transceiver model. Cable carrypower for MK and all interfaced
signals includingaudio, computer CAT port and all kinds ofkeying. An independent cable comingfrom the
DB37 connects the transceiver front panel microphone jackand MK.
The remainingconnectors at the rear panel ofthe MK are dedicated for external accessories as footswitch,
paddle, microphone ...
MK works in two modes - with computer or without computer. Switchingbetween these modes is
automatical.
Ifcomputer is not connected or not running, MK works usingthe "default" settings. Those settingcan be
customized. In this mode MK provide PTT sequencer controlled byfootswitch or hand mic PTT, drive all
PTT outputs and works as a CWmemorykeyer.
Ifcomputer equiped with Windows OS is connected and "microHAMUSB Device Router" program is
running, MK works as before plus as an Interface. It transfers all digital and analogsignals generated by
computer loggingprogram to the transceiver and back. Compatibilitywith loggingsoftwares is ensured by
usingvirtual serial ports created byRouter program. Router continuouslymonitors these virtual ports, logs
everyevent on them and transfers all these events via USB to the MK. MK is parsingthese data and
resends them to the physical ports oftransceiver as CAT, FSK, CW, and vice versa.

EXTERNAL KEYBOARD
MK offers the possibilityto generate FSK and CWsignals from directlyconnected PS2 keyboard. For
playingbackstored CWmessages the numeric PS/2 keypad is sufficient.
Keyboard input has two modes, CWand RTTY. Power up default mode is CW. User can switch between
modes usingthe "CAPS LOCK" key.
CWmode allows to playthe characters, play/record messages from/to internal memories, set the WPM
speed, tune function and the side tone. It has two submodes for playingand recording. Duringrecording
mode it is possible to record characters written on the keyboard or played on the paddle.
Keyfunctions in CW playing mode:
Num Lock - Start CWrecordingmode
Num [1- 9] - Playmessage stored in memory(keynumber means memoryindex). Ifnumber
immediatelyfollows the key"num del" it redefines the repeat interval
Num Del - Repeat message (default interval is 1 second, it can be changed bypressingthe
number ie. 1.3 means MEM1 in cycle 3 second)
Num + - Increase WPMspeed (step is defined in configuration from USB Device Router)
Num - - Decrease WPMspeed (step is defined in configuration from USB Device Router)
Num Enter - Retrieve WPMspeed accordingto speed pot
Num * - Tune (can be canceled bykeys NUM0 or ESC, also bypaddle)

11. AUDIO SETTINGS
There are three parts ofaudio settings:
1. Computer sound card mixer settings
Howthe sound card is handled depends on logger programs capabilities. Some loggers can directlydrive
sound mixer controls and settings, several also in conjunction ofcurrent state ofoperation. In general keep
this advices:
2. USB Device Router Audio Switching
MK is verystrongin audio handlingand switchingbetween computer and transceiver. For description
please lookat chapter 12, USB Device router / Audio.
3. MK and transceiver level settings
There are two knobs for adjustingaudio drivinglevels.
1. First marked as "COMPUTER" serve for adjustingaudio signal level comingto computer Line In input.
2. Second marked as "RADIO" serve for adjustingaudio signal level comingto transceiver AF IN or MIC IN
input. Because transceiver AF IN and MIC IN inputs handles different levels, correctlyattenuated level
for MIC IN must be adjusted byspecial "trimmer". On the bottom PCB at the right side next to the
15
PLAYBACK
1. Open Windows Mixer settings and choose
Playback settings
2. Check"Volume Control" and "Wave"
3. Move sliders to the one halfofway
4. Be sure that the controls are not muted.
RECORDING
1. Open Windows Mixer settings and choose
Recording settings
2. Check"Line In" and "Microphone"
3. Move sliders to the one halfofway
4. Select Line In

microHAM© 2004 All rights reserved
transformer there is a small white "screwdriver" trimmer. You can access this trimmer bya small hole
located at the right side ofthe top cover. With this trimmer you can select a portion ofthe audio level
from main MK front panel RADIO pot for radio MIC IN. This portion oflevel is applied when audio routing
"C" is selected in the Router - Audio Switchingtab. Followingapproach is recommended:
a) Select MK RADIO pot to about three o'clockpossition.
b) Select routing"B" for transmitingfrom computer (audio goes to rigAF IN) and usingwindows mixer
sliders adjust appropriate (not overdrived) level.
c) Select routing"C" for transmitingfrom computer (audio goes to rigMIC IN) and usingtrimmer and
transceiver MIC GAIN adjust appropriate (not overdrived) level.
This approach allowyou to use front MK RADIO pot for both routingB 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 selectingintegrated
preamplifier inserted between attached microphone to RJ45 MIC jackor EXT MIC jackand computer
MIC IN input. Turningpreamp ON is not neccessaryfor electret microphones as are used with Icoms
radios. Turn this preamplifier ON for Kenwoods and Yeasus original dynamic microphones (also Heil).
Bydefault factorysettings, this preamplifier is bypassed.

12. USB Device Router
MicroHAMUSB Device Router (router) is a program that provides configuration tool for MK and software
interface to another applications in the form ofvirtual serial ports.
To use the MK with anyWindows based loggingprogram (and configure it) it is necessaryto have installed
its driver and run the router.
Set up and Operation
Router can handle several devices (micro Keyers or microHAMUSB interfaces) simultaneously. Each
device has its own tab (page) in the main notebookcontrol. Content ofa device page depends on device
type. For example, USB interface has a simple page with onlyseveral controls that allows to associate the
interface with virtual serial port(s). On the other hand, micro Keyer has more complexcontrols organized in
several subpages that allows also to change keyer configuration. Device tab is created when a device is
first time detected byrouter and remains in router even though device is disconnected. Automaticaly
generated device name (displayed on tab) can be changed usingthe menu command "Device/Rename". To
remove the page ofdisconnected device use menu command "Device/Delete".
User can specifyifrouter has to be started at system start-up and ifit starts minimized. See the menu
"Router". This menu contains also item "RT priority". Ifit is checked the router run with real time priority.
Check it only if you experience that your logging program does not correctly pass the CWsignal.
After adjustingall the settings use the router minimized to system tray.
Virtual serial ports
First ofall it is necessaryto create several virtual serial ports (COM) because this is the onlywayhowthe
applications (loggingor control softwares) can access microHAMdevices.
One or two COMports will be enough for one microHAMUSB
interface. It depends ifloggingsoftware supports keying(CW/PTT)
on the same port as radio control. Ifnot, router give you the
possibilityto use this software with onlyone microHAMUSB
interface.
MK will need more COMports because it integrates more channels
(radio control, FSK, WinKey, CW, PTT, foot switch feedback).
Use menu command "Virtual Port/Create" to create virtual COM
ports. It is possible to select more ports at once. Don't select the
name ofsome real COMport that is present in the system to avoid
conflicts. Select onlyCOMports that are supported bylogging
software you intend to use. Creatingofvirtual port maytake a long
time (several tens ofseconds) on Windows 98/ME, be patient. It is
possible to delete anyvirtual port at anytime in the future.
17

microHAM© 2004 All rights reserved
Routing
Once virtual ports are created theycan byassociated with some device channels (e.g. FSK channel in MK).
Use subpage "Ports" ofMK page or device page ofUSB interface for this purpose. These "routing" settings
need to correspond to settings ofloggingsoftware.
USB interface has four channels:
- serial channel for radio control (uses serial data signals RX and TX)
- output signal CW(uses DTR)
- output signal PTT (uses RTS)
- input signal Foot Switch feedback(uses CTS)
All these channels can share the same COMport, because theyuse different serial port signals.
MK has sixchannels:
- serial channel for Radio control (uses serial data signals RX and TX)
- serial channel for FSK (uses serial TX data)
- serial channel for WinKey(uses serial data signals RX and TX)
- output signal CW(uses DTR or RTS)
- output signal PTT (uses DTR or RTS)
- input signal Foot Switch feedback(uses one ofCTS, DCD, DSR or RING)
Serial channels (radio control, FSK and WinKey) have to be associated with different COMports but I/O
signals (CW, PTT, Foot Switch) can share the COMport with anyofthem.
18

microHAM© 2004 All rights reserved
Device Settings
MK contains internal configuration. Default configuration is loaded from internal non-volatile (EEPROM)
memory. These settings cannot be changed without connection to the computer.
When MK is connected to the computer (with runningrouter), settings are overridden bysettings from the
router.
Anychanges ofthese settings on subpages "Audio", "PTT/FSK", "CW/WinKey" are applied immediatelyto
MK. Default settings stored in EEPROMare not altered in this way. It means that ifmicro Keyer will be next
time powered without connection to computer it will use the old settings stored in EEPROM. To change
these default settings use button "Store as Default" placed on all related subpages or use menu command
"Device/Store Settings as Default".
Last subpage "Messages" allows to set the WinKeymessages that can be stored to EEPROMofmicro
Keyer. These messages can be used in operation without computer. Theycan be played (and modified)
usingexternal keyboard or num pad. Messages are NOT a part ofthe settings that are applied
automaticaly. To store them use buttons "Store" or "Store All".
Settings and messages ofindividual devices can be stored to file too. Use menu commands "Device/Save
Settings to File" and "Device/Load Settings from File". Settings are described in detail bellow.
Firmware
Thanks to the FLASH core technologyofthe internal
CPU, changingfirmware is as easyas installingnew
version ofthe computer software. You will not need
anyspecial HWor SW, firmware can be downloaded
from our website and changed directlyfrom the router.
MK firmware can be upgraded usingmenu command
"Device/Upload Firmware".
Presets
Requirements ofthe loggingor control programs are different and it is hard to find universal settings for all
your favorite loggers. One is good for SSB contesting, another is better for digital modes another for FSK
RTTY etc. For easyswitchingbetween loggers, router has built-in configurable presets. You can store
different keyer settings to these presets, rename each preset and switch between presets in a second
simplybytouchingthe preset button.
Each preset contains settings ofall devices (without messages ofmicro Keyers) and routingsettings
(assignment ofCOMports to device channels) too.
19

microHAM© 2004 All rights reserved
To create, modify, rename or delete a preset use commands from
menu "Preset". Number ofpresets is limited to twelve (12).
There are several ways to applysome preset. You can use
command from menu "Preset" where all created presets were
added as menu item. Also pop-up menu invoked byright clickon
the system trayicon when the router is minimized contains these
items. The another wayis to push the preset button. To show
preset buttons the menu item "Preset/ShowButtons" must be
checked. Buttons are placed above the status bar and contain
control lamps that indicate which preset is currentlyapplied.
Presets are stored to the registryat program exit together with the
current router state.
Audio
With MK you can define audio switchingfor each preset. MK can route three audio lines from/to computer
sound card (LINE IN, LINE OUT and MIC IN) and three lines for transceiver AF IN, AF OUT (radio rear
panel) and MIC IN (radio front microphone input). You can define position ofaudio switchingfor each
operation state.
States can be:
1. RX = receiving
2. TX - PTT = transmitting(anyPTT event except foot switch or hand mic PTT event)
3. TX - Foot switch = transmittingwith pressed foot switch or hand mic PTT (foot switch event)
Switchingpositions are:
A- Audio output from radio goes to sound card Line In. Audio output from
computer is disabled and microphone is connected to the radio front mic
jack.
B- Audio output from radio goes to sound card Line In. Audio output from
computer is enabled and goes to rear radio AF In. Microphone is
connected to the computer sound card mic jack.
