Page 27: Device Configuration Tabs
© 2006 All rights reserved DEVICE CONFIGURATION TABS There are ten (10) tabs for configuring MK2R. Each tab controls part of MK2R's functions. Except for the CW Messages and FSK Messages tabs, any change is applied immediately to MK2R. Changes in the Messages are only applied in response to the Store or Store All buttons. -
Page 28: Ports Tab
© 2006 All rights reserved PORTS TAB Once the virtual ports have been created they must be associated with a specific function or device channel (e.g., Control, CW, PTT, etc.). These assignments should correspond to settings of the application software and must be configured first in Router then in the application (e.g., logging or digital mode program). - Page 29 © 2006 All rights reserved TIP: If the application permits, always configure the Radio Control port to use two stop bits. Communication is a little bit slower (9%) but more reliable. Data flowing through the Control channel is indicated by two arrows. A green arrow shows data flow from the host application to the radio and a red arrow shows data flow from the radio to the application.
- Page 30 © 2006 All rights reserved Unfortunately, many radios fail to provide a separate mode for digital operation or the control protocol implemented in the radio does not report the digital mode when operating AFSK, PSK and other audio based digital modes. This is true for all Kenwood transceivers as well as many Icom and Ten-Tec radios.

MK2R. If you want to completely disable all polls, select "none" instead of the radio model in the Radio box. Warning: Always select "none" when configuring microHAM Band Decoder through MK2R. FSK PORT The FSK channel is used by the application program to send the FSK keying signal. FSK is used primarily for RTTY. -
Page 32: Ports: 2 Ports: Cw
© 2006 All rights reserved The virtual port used for FSK can also support PTT (required by MMTTY). When you use MMTTY, select the PTT box and RTS will used for PTT. Do not use the FSK port for any other function. -
Page 33: Ports: Ptt
© 2006 All rights reserved PTT PORT The PTT channel is used to control transmit/receive switching of the transceiver, Power Amplifier and Low Noise Preamplifier (LNA). An internal sequencer assures 100% protection against transmitting through the LNA or hot switching of the PA when the PTT channel is used. More information about T/R switching, MK2R PTT outputs and the sequencer is provided under the PTT/FSK tab. -

- Page 40 © 2006 All rights reserved FIXED and FOLLOW RADIO Audio Switching Router provides two modes to select the audio configuration, Fixed and automatic - Follow radio mode. TIP: If Router can read frequency and mode from your radio (Ports tab | Set) use Follow radio mode.
- Page 41 © 2006 All rights reserved When Router is able to read the operating mode, Follow Radio provides the greatest flexibility and ease of operation. The same settings are available as with Fixed Mode but switching among them is automatic based on the operating mode (and, optionally, frequency).

Page 42: Audio Mixer Tab
© 2006 All rights reserved AUDIO MIXER TAB The sound card configuration depends on the capability of your application software. Some software can directly control the sound mixer, some can not. Router's Audio Mixer tab provides exceptional control over the sound cards or codec with all level settings stored in the presets for each program (or configuration). - Page 43 © 2006 All rights reserved Note: Because Windows can reassign sound cards while in use, Router may not invoke the proper mixer. To check that the proper mixer has been assigned, click the Get ID button and confirm that the proper sound card is selected.
- Page 44 © 2006 All rights reserved If you need to adjust the transceiver drive level during operation you can use the front panel controls and leave the settings in the Audio Mixer untouched. Knob TX1 (11) adjusts the drive for RADIO1, knob TX2 (14) adjusts the drive for RADIO2.
- Page 45 © 2006 All rights reserved Some tips from Geoff Anderson, G3NPA: TIP: If you have achieved the correct settings for the transmit levels, you will see that changing from the PSK tuning tone to typing text, will make the transmitter power swing from 50% (no typing) to 100% (typing or tuning-tone) as observed on an RMS or average reading meter.

Page 46: Ptt/Fsk Tab
© 2006 All rights reserved PTT/FSK TAB On this tab you can configure operation of PTT and keyboard FSK. This defines the interactions among the multiple PTT input and the PTT outputs. PTT INPUTS MK2R has several PTT inputs available for each radio:... - Page 47 © 2006 All rights reserved PTT OUTPUTS MK2R has four (4) PTT outputs for each radio: PTT1, PTT2, PAPTT and LNA PTT. PTT1 and PTT2 are brought out to the DB37 Radio connector. PAPTT and LNA PTT are RCA jacks for connecting to external devices.
- Page 48 PAPTT will be activated immediately and PTT2 will be activated with the delay defined in PTT delay. This unique feature of microHAM products prevents hot switching during FSK operation. Because a radio in FSK operation begins to produce RF as soon as it enters the transmit mode, the application program cannot guard against hot switching.
- Page 49 © 2006 All rights reserved DIGITAL modes are: PKT, DIG and DATA. There are four available settings. PTT2 Immediate is – appropriate for applications which provide for setting a PTT lead time. PTT2 delayed should be used with applications which do not permit setting a PTT delay. PTT1 immediate should be used when radio does not have a dedicated digital mode input and you must use the microphone (or Patch) input.

Page 50: Cw/Winkey Tab
© 2006 All rights reserved Invert FSK: Unlike AFSK, an FSK signal cannot be inverted by most application programs (like MMTTY) because the UART used in a normal serial port lacks that capability. Since MK2R is a software defined interface it can be made to invert the FSK signal. When the Invert FSK box is checked MK2R changes the “at rest”... - Page 51 © 2006 All rights reserved CT space - Selects “contest” word space (six dits long instead of seven).

The second way uses microHAM command protocol via a virtual port. Note: the microHAM protocol is under refinement in conjunction with the authors of most of the leading contest logging packages. Software developers who would like to implement native control of the MK2R and MK2R+ should contact OM7ZZ@microham.com. - Page 56 © 2006 All rights reserved Each signal can be inverted if necessary. The state of the signal is represented by a RED arrow. "Follow TX focus" is a special setting that does not require separate application control. Headphone audio is selected automatically with with the transmit focus.
- Page 57 © 2006 All rights reserved Use classic auto mode: when used, MK2R does not use advanced headphone audio combinations. Headphone switching behaves the same way as classic SO2R controllers. Stored functions will be also simplified but the content of the stored scenario will be retained. This allows classic mode to be turned on/off without the need to modify the stored function (scenario).
