General information (setting up microHAM and N1MM logger)
In this document information is gathered about setting up the
freeware contest program N1MM logger with the microHAM MK2R+ SO2R
controller and Station Master banddecoder.
The original text from Joe, W4TV has been used as a start for
this document and updated
with texts from Pete, N4ZR his SO2R-only document. Also
the N1MM and microHAM reflector are used and of course own trial and error.
This document has multiple sections. The information decribed is
being used at the stations PA1T (Timon) and PA1M
Choices have been made depending on the equipment used at these
stations (PC, Radios etc). As an example: My PC has only 1 serial port
so there is room for 7
virtual ports in uRouter in combination with N1MM logger. The shack PC
has 3 serial
ports, so only 5 virtual ports are left to use and the LPT port is
I’d like to thank all who have written about the
combination with N1MM
logger. Especially I’d like to thank Joe, W4TV and Pete, N4ZR
have put on the web, reflectors and in personal e-mail to us. Thanks to Tom, N1MM for
adding the microHam protocol to N1MM logger.
This information is placed on the web in the hope that
it may help others in setting up the microHAM MK2R+ SO2R
controller. The setup below is working for us but
might not work at your place. The MK2R+ is a very complex
hardware/software combination as it can be set up in so many different
Firmware updates and router versions
It is neccesary to have loaded the CORRECT firmware version for each version of Router.
Each Router install file includes a firmware file. However, Router will only
prompt for to load firmware if the installed version is OLD (reverting is
not expected). Comparing the change logs for Router and the firmware
for the MK2R, Router 7.1.5 requires firmware 4.2 Whenever firmware is changed, new "Power-up settings" must
be saved to the interface (except USB II) and power must be cycled in
order to properly initialize the controller in the interface. The
firmware gets loaded to the interface - leaving the file on the computer
does no good. Having a mismatch between firmware and Router will almost
guarantee problems with PTT and switching.
Router tells the firmware of the MK2R at the bottom of the router Screen. Just before the Winkey rev.
The exe file (download) is the same for update or fresh install.

Proposed Virtual Port numbers
Note: The absolute port numbers do not matter. The key is consistency -
the same port number must be used for a specific function every time it
is used. The port numbers below will be used (as proposed by Joe, W4TV).
|COM 3 - WinKeyer
||(it is best to assign WinKey
to the lowest port to
avoid loss of CW if
another port is activated for CW)
|COM 4 - Radio #1
||(PTT and Footswitch is optional on this port)
|COM 5 - Radio #2
Footswitch is optional on this port)
|COM 6 - Digital #1
and PTT for
Radio #1 (assign Radio 1)
|COM 7 - Digital #2
Radio #2 (assign Radio 2)
|COM 8 - MK2R
The porposed ports below are used at PA1M where PA1T does not have COM 3 and also uses the LPT port.
Clean up your Com Ports
for those who want to clear out those low number ports that don't need
to be cluttering up your Device Manager listing anymore, you can follow
1. Click Start
2. Click Run
3. Type cmd.exe in the textbox and click OK
4. Type set devmgr_show_ nonpresent_ devices=1 and hit ENTER
5. Type cd\windows\system32 and hit ENTER
6. Type start devmgmt.msc and hit ENTER
7. When the device manager opens, click the View menu
8. Click Show Hidden Devices

73, Bob W5OV
Ouch it's not working - please check
a.. Confirm that you have selected the correct soundcard for audio in N1MM and microHAM Router.
b.. Confirm that you have selected the correct wave file path in N1MM Logger.
c.. Confirm that you have the correct audio connections between microKEYER and the soundcard (all three cables).
d.. Double-check the preamp setting (jumpers) in the microKEYER (enabled for dynamic mic, bypassed for electret mic).
e.. Confirm that any wave files are being played back on the left channel of the soundcard (microKEYER uses left only).
For debugging purposes it is very convenient to connect a set of
powered computer speakers in parallel with the soundcard "Line Out"
(microKEYER SOUNDCARD OUT jack).
b.. If you hear the proper audio but it doesn't reach the radio, the issue is in microKEYER's audio switching ...
c.. if you do not hear the right audio the issue is in the software (N1MM Logger or Windows).
Refer to the Set-up Guide for microKEYER and N1MM Logger for Router
configuration information and the N1MM Logger manual for N1MM
e.. microKEYER/N1MM Set-up Guide is available through the "Download Documents" link in Router's "Help" menu.
Q. Where are the MK2R settings stored
A. Using Router version 5 and up: C:\Documents and Settings\All
Q. How to set up WYH on the MK2R
A. When WYH is selected it simply switches the headphone feed to the
USB Audio CODEC andrecords 'what you hear'. The audio
settings selected by the RECORDING/DIGITAL LEFT/RIGHT controls are
ignored. WYH is designed to be able to record 'what you hear'.
WYH is headphone audio and will be effected by the radio volume
Q. How to setup SSB
What kind of microphone are you using and how is it connected?
You MUST set the jumpers correctly on the Live mic preamp
based on the type of microphone and you must configure the soundcards
correctly in Router.
If you can play a wave file via USB Voice CODEC, the CODEC
installed (it is built into Windows and not a microHAM driver).
However, N1MM Logger REQUIRES that the Audio Settings tab (in N1MM
Logger) is set up properly to select the correct inputs.
Further, if your computer has a motherboard soundcard that uses the
RealTek HD audio chipset (or an add-in soundcard by SoundMax with the
RealTek HD audio chipset), N1MM Logger will often select the wrong
input unless USB Voice CODEC is the Windows Default sound device (bad
idea) because of issues with the non-standard RealTek driver.
Finally, MK2R+ MUST be in VOICE mode and the audio switching must be
correct so that the microphone is switched to the sound card when you
are recording ... there are three possibilities depending on whether
you are trying to record on air or not and whether the logger activates
MK2R+ audio switching should be CmCmA or CmCmCm and you should not
press the PTT while recording. Radio(s) must be in SSB mode and Router
must know that (black box around the VOICE switching
Q. My TX audio is not working anymore
Uninstalling and reinstalling Router will not change a thing with the
CODECs. You are wasting your time.
Confirm that the microphone is connected correctly, the proper
microphone input (front or back) selected, the correct CODEC assigned
to the Voice and Digital/Recording sides of Router, and the proper
CODEC assigned in the audio switching.
It is very easy to overlook the subtle difference between Voice and
Audio CODEC in both the Audio Switching tab and the Audio Mixer tab.
I would also confirm that Windows has not done something strange like
install another audio device, or change the order in which the CODECs
are installed. Click on the Get ID buttons and be sure that Wave IN ID
= Wave Out ID = Mixer ID. Confirm that the "Soundcard name in the "Get
ID" box is the one you expect (that it matches the selected soundcard).
Q. TX Mic pull down does not offer "microphone" as a selection option. My laptop only has only mic in and line out.Q What is the "blinking Busy light"
A. If the TX Mic select box on Router does not offer a microphone
chose, the sound card does not support echoing the microphone to the
speaker/headphone output and you will not be able to route the
microphone through the laptop sound card or change DVK messages "on the
You will still be able to record and playback messages with the N1MM
Logger DVK but you will not be able to record while doing so. Configure
your audio switching for ACA ... this connects the mic directly to the
radio "at rest" and when the hand mic or footswitch is pressed and
connects the DVK
output to the radio when the computer PTT is active. When recording a wave file, do not press the hand mic PTT or footswitch.
"blinking Busy light" is a "same band lockout." It will happen any time
MK2R/Router loses CAT data from either radio and is a safety to prevent
manually putting both radios on the same band (protect the rig front
end). Check (and reset) your presets to find out which one has a
bad radio configuration.
Q. I couldn't find an "Apply" button or similar.
A. If you make a change, the change is applied immediately. If you want
to save that change to the preset, use "Preset | Save As" to update
(over write) the existing preset.
Note, you will probably want to set the
VOICE/DIGITAL box on the Audio Switching TAB to "Use Voice Settings"
for this weekend. Since TenTec does not include an AFSK mode in their
radios/CAT command set, Router must determine Voice/Digital mode by
operating frequency. By default operation between 7030 and
7045 is considered to be "DIGITAL" (AFSK).
Be sure to UNCHECK the "Mute mic on supported radios" box on the N1MM
Logger Configurer "Other" tab. N1MM expects to run DVK via the AUX
connector on the Orion. MK2R uses the mic input.
Q. How can I record SSB- and/or CW-QSOs in N1MM with
SO2R/1R-configuration and MK2R+?
A. On CW, you can do it by selecting the USB Audio CODEC in N1MM's
configurer|Audio tab. On SSB you have to choose between the N1MM DVK
and recording, because the Audio tab in the configurer does not allow
you to set a different soundcard for recording and DVK purposes
Q. Function keys in SSB: Should I use the N1MM-DVK or the
MK2R+ - DVK? Which is better?
A. I would use the N1MM DVK because it allows for full integration
between N1MM functions and the DVK, and use a separate recording
Q. Which sound card driver to select in Windows
Q. I'm missing some virtual serial ports, can't select them, can;t create them
Windows automatically selects any newly installed audio device as the
default device for Sound Playback and Sound recording. This is
undesirable as Windows Sounds would be played through MK2R+ and onto
For Windows 2000 or Windows XP. right click on the
Speaker Icon on the task bar and select "Adjust Audio Properties" or
open "Sounds and Audio Devices" in Control Panel and reset the Default
device for Sound Playback and Sound Recording to your computer's
primary sound device.
For Windows Vista, right click on the
Speaker Icon on the task bar and select "Playback Devices” or open
“Sounds” in Control Panel and reset the Default Playback device to your
computer's primary sound device.
A. First try to delete all virtual ports from within router and create them again.
this does not help remove all virtual ports from within Windows (System
from within the Configuration screen), after deleting all ports they
will be automatically created again (and hopefully also the lost ones).
It worked here..
Q. Do I have the Realtek sound card driver problem?
A. Select "microHAM CODEC" in the Audio Mixer tab and click, "Get ID". If
Wave IN ID <> Wave Out ID <> Mixer ID (ie. they do not have all the same number) you have the "Realtek
problem" where the application is using the Mixer ID instead of the
WAVE IN ID to select audio input.
Q. Using CAT and 2nd CAT ports
A. As two programs CAN NOT under any circumstances look at the same port
simultaneously. That is the reason for the CAT and 2nd CAT ports in Router
... the primary logging/control program looks at the CAT port to control the
radio and the secondary program (e.g., CW Skimmer, Spectravue, PowerSDR,
etc.) looks at the 2nd CAT port for Icom "transceive" broadcasts, Kenwood IF
data or slow speed (< 500 msec) polling with older Yaesu rigs to get
the operating frequency for synchronization.
Q. Where are router's settings and presets stored?
settings and presets are stored in the Windows registry. The stored
settings are updated when Router is closed. Any "registry
protection" or "registry backup/restore" program will prevent saving
the settings (by restoring the previous state). In addition, if
Router does not close properly, the settings will not be saved.
Q. How works the virtual serial ports
A. The Eltima virtual serial port is a software interface e.g.,
it provides software equivalents to the various buffers and registers
of an 8250 compatible UART - for OEM specific hardware and software.
For Router, the Eltima VSP code provides an interface compatible with
the Microsoft Communications Toolbox. The data to/from the foreign
applications is transferred to Router which reformats it into a
microHAM proprietary multiplexed data stream (Radio_1 CAT, Radio_2 CAT,
Control - which includes the various PTT, Footswitch, audio routing,
and PC generated CW flags - and WinKey channels) and sends it via a DLL
interface at 230Kbps through the USB port and the FTDI UART in the
interface to the microcontroller in the specific interface.
microcontroller then demultiplexes the data and distributes it to the
appropriate process in the controller. CAT and WinKey data is put in
standard ASCII form and handled by UARTS in the controller. The various
control flags are acted on by the firmware to generate the necessary
internal or external controls.
If Router and the microHAM
interface are not running, the VSP should either not exist (Router not
running) or return an error (interface not running).
ports created and defined by Router can only be used to communicate
with or control devices that are attached to a microHAM interface. Just
as with a "real" port, only one program at a time may open a virtual
serial port and no two ports (virtual or real) may have the same
address (COM number).
Q. MK2R+ and Vista / Windows 7
works with Vista. However, since Vista no longer allows an application
(Router) to control the audio endpoints, it is more difficult to
set-up. In effect, the user needs to use the Vista Volume Mixer to
select each device/endpoint and set the level of that endpoint for each
individual application (e.g., separate settings for Writelog, N1MM,
WinTest, DX4Win, MMTTY, DXLab Suite, etc.).
Vista / Windwos 7 you will need to make "USB Voice CODEC" (headset
microphone) the default input device for the OS and "USB Voice CODEC"
("headset speaker") the default output device for the OS. Disable all
Windows sounds and replace the default "ding" with "silence.wav" Then
set the N1MM Audio device to "default."
Q. No microphone audio - what to check..
1) what microphone are you using?
2) is it connected to the front or rear mic jack of the MK2R+?
3) is the front panel switch in the correct position?
4) if the microphone is an electret mic do you have the soundcard preamp bypasses?
5) if the microphone is a dynamic mic is the soundcard preaamp enabled?
6) Do you have the correct soundcard (USB Voice CODEC) selected for
voice operation (left side of the audio mixer tab)?
7) Did you click on the "REC MIXER" button, confirm that that the mixer
for the correct soundcard is opened and the microphone is not muted?
8) you should not press the PTT/footswitch when setting the REC MIC
level and "On Air Recording" should not be selected on the DVK tab.
Q. Reset MK2R/Microkeyer/Digikeyer settings
Save Power up settings to reinitialize the EEPROM in microKEYER, close Router to save the settings and then restart Router.
FSK or CW messages
PTT ON/OFF is not supported as an embedded command in the MK2R. Use the F10
key from the PS/2 keyboard.
RF problems with my MK2R
The bypass modification for the microKEYER II has not been evaluated for the MK2R+. However, due
to the layout it will not be as simple as the microKEYER II version. Circuit
grounds for the USB "core" and the balance of MK2R+ are separated and there
is no conveniently located place for field installable bypasses.
Difference uRouter K3 VS Patched K3 two radio settings?
is a difference in the way the two settings behave when the radio is
turned off. The "K3" setting will buffer polling data from a connected
logging program as long as it runs. The "patched" setting will discard
polling data if the K3 does not respond (is turned off).
"PTT line" (usually
RTS) on a serial port
One note with regard to N1MM Logger (and other logging/control software) ...
DigiKeyer and other microHAM interfaces responds to the "PTT line" (usually
RTS) on a serial port. The interfaces do not respond to "PTT via command."
In using N1MM with microHAM Router, it is best to set the PTT delay
in N1MM slightly longer than the PTT Lead (microKEYER, microKEYER II,
MK2R/MK2R+) or PTT Delay (DigiKeyer) parameter. N1MM Logger will begin
producing audio (AFSK or Voice macro) when its delay time expires. If
Router's PTT Lead/PTT Delay is longer, the transceiver will not have
N1MM Logger starts generating audio. A good starting point
is to set N1MM Logger PTT delay to 20 msec and Router's PTT Delay to 10
msec. If the particular configuration does not require a delay for receive
antenna switching (LNA PTT) and the logging/control program provides its own
PTT delay (like N1MM), it is even possible to set Router's PTT delay to
Always uncheck "PTT via command" when using microHAM Router. If "PTT via
Command" is used, the PA PTT and/or LNA PTT outputs on the microHAM
interface are not usable because Router and the keyer have no way of knowing
that N1MM Logger has commanded the radio to begin transmitting.
PTT delay setting in N1MM Logger and the PTT lead or PTT delay settings in
microHAM Router should be adjusted for the particular installation. The PTT
Lean/PTT Delay setting in Router should be less than the PTT delay in the
logging program. Router's PTT Delay will control the delay between PA
PTT/LNA PTT activation and the activation of the transceiver PTT. The logger
PTT will control the delay between activation of PA PTT/LNA PTT and the
start of RF.
If the PA relay was very slow one might set PTT delay
in N1MM Logger at 40 mSec and set PTT Lead/Delay in Router at 30 mSec.
In that case PA PTT would activate as soon as the operator pressed an
F-key while the radio PTT would activate 30 mSec later and RF (audio/CW)
would start 10 mSec after the transceiver PTT. With hand mic PTT, the
amplifier would still receive its PTT command 30 mSec before the transceiver
to allow time for the (slow) relay to switch and settle.

Relays Station Master (Rotator interface adding a Tailtwister rotator)
All of the relays in Station Master are Forward model N4100HS3DC12. The
specification on the case says: 3A/125VAC/30VDC.
Tailtwister is specified at 2.25A operating, remember that the starting
surge will be higher and there will be a substantial voltage "kick" on when
the relays. The relays in the Station Master won't handle the currents required by the
Tailtwister, so it was necessary to use some SPDT power relays with 20A
contacts and 12V coils that I obtained at a local electronics surplus outlet
to buffer the Station Master relays. The power relay NO contacts were simply
wired across the CW, CCW and Brake switches in the Tailtwister control box.
The SM Analog Input was taken directly from Terminal 3 of the control box
and the Analog Ground was wired directly to Terminal 1 of the box. Below in detail how to add a Tailtwister rotator.
got my Station Master working great controlling a Tailtwister. You MUST
use three 12V coil external relays with contacts rated for 10A or
better to interface with the Hy-Gain box. The currents involved,
especially with the brake circuit, are far too high for the SM relays
to handle. Here's how you want to connect the thing up:
the first relay, the Brake buffer relay, with its normally open (NO)
pair of contacts directly across the NO contacts of the Brake switch in
the Hy-Gain box. You can just put the relay contacts in parallel with
the wires that are already on the Brake switch.
2. Wire relay number
2, the CW buffer relay, with its NO contacts across the CW Rotation
switch. Connect the common of the relay to the 24VAC line at terminal 2
of the terminal strip on the rear of the control box. Connect the NO
contact of the relay to terminal 6 of the control box terminal strip.
Wire relay number 3, the CCW buffer relay, with its NO contacts across
the CCW Rotation switch. Connect the common of the relay to the 24VAC
line at terminal 2 of the terminal strip on the rear of the control
box, or just connect it to the common of the CW rotation buffer relay.
Connect the NO contact of the relay to terminal 5 of the terminal strip.
With the buffer relays taken care of, it's now time to wire the
controls for the relays from the Station Master. How you do the
interconnect is up to you. I made a "dongle" using a DB9 female
connector that protruded from the rear of the control box and then
built a mating control cable with a DB9 male connector on the control
box side and a DB15 male connector that connects to the Station Master
5. The positive side of all three buffer relay coils
should be wired to the +12V supply from the Station master that is
provided on Pin 1 of the DB15.
6. Wire Pin 3 (CW-COM), Pin 6
(CCW-COM) and Pin 12 (AUX-COM) to Pin 9 (Power Ground) at the DB15
connector plug. Also be sure to ground the shell of the DB15 connector.
If your relays don't have them built in, wire snubber diodes across the
relay coils. Connect the diode cathode to the positive coil terminal
and the diode anode to the negative coil terminal. General purpose
diodes such as 1N914, 1N4148 or rectifier diodes such as 1N4001, etc.
will work equally well. We need these to protect the relay contacts in
the Station Master from the inductive spike generated when the buffer
relays are switched.
8. The negative terminal of the Brake buffer relay coil should be wired to Pin 4 (AUX-NO) of the DB15.
9. The negative terminal of the CW buffer relay coil should be wired to Pin 10 (CW-NO) of the DB15.
10. The negative terminal of the CCW buffer relay coil should be wired to Pin 13 (CCW-NO) of the DB15.
The Analog In at Pin 15 of the DB15 connector must be wired DIRECTLY to
the high side of the rotator position pot at terminal 3 of the terminal
strip on the rear of the control box. Try to keep this wire short and
route it well away from the large 24VAC power transformer in the
control box. This transformer is a fierce radiator of 60Hz, and we
don't want it getting into the Station Master's sensitive sensor input.
The Analog Ground at Pin 8 of the DB15 connector must be wired DIRECTLY
to the control box common at terminal 1 of the terminal strip on the
rear of the control box. Don't be tempted to connect it the control box
chassis. The (rather poor) design of the Hy-Gain control box returns
the substantial brake solenoid and motorcurrents to the power
transformer via the chassis, and connecting the sensor common anywhere
but directly to the rotator position pot wiper at terminal 1 will
create a ground loop and cause 60Hz position measurement noise. Use as
short a wire as possible for this connection as well.
hookup will work fine. I've been using mine for several months now with
no problems. There is one oddity of interfacing the Station Master this
way: The CW and CCW direction LEDs on a Tailtwister control box front
panel will NOT illuminate when the rotator is turning. This is because
the normally closed contacts on the rotation switches in the control
box short the LEDs.
I hope this information is useful. If there
is any interest I will be glad to post a drawing in the group Files
area detailing the interface schematically.

Cahange the setting or deselect when not used. Dont forget to Store this information to the Station Master...
Antenna lock out between Station Masters.... NO
With two Station Master controllers, one unit does not know which antennas
are selected by the other controller. There is no provision for sharing
rotors between the units - but the firmware/software continues to evolve.
Networked resource sharing of rotors, SteppIR antennas, etc. are features planned for Station Master Deluxe.
With the present software, rotor control is tied to selection of an antenna
on the rotor. There are two "solutions" - first use a separate RS-232
interfaces rotor controller with the "auxiliary" port or second define all
antennas as being on the rotor.
Antenna rotor resources are not shared among multiple Station Master
controllers. The rotor control, SteppIR control and amplifier control
are bound to the Station Master and transceiver to which it is
connected. Antennas are shared using a Double Ten Switch with each
Station Master controlling one "side" or set of outputs.
Station Master can interface with a stack switch by defining each
configuration as a separate antenna. However, if you do that you will
need to design an external relay network to switch the stack switch
control lines between the two Station Master controllers so that the
"active" Station Master is controlling the stack switch.
Timing is controlled entirely by the transceiver. PA PTT is a copy of
the PTT IN signal, LNA PTT is a copy of the PTT IN with a release delay
set by the PTT Tail parameter. As relay keying is rather slow,
always (when possible) enable solid state keying instead of relay
keying (it could solve hot switching ).

the inhibit inputs (make sure they are not enabled if you do not have
hardware that supports inhibit) and make sure you do not have any other
frequency dependent device that might be "out of range."
No audio on line in
CAT noise : Buzzing sort of doo doot sound in
the background of the record
This is CAT polling noise. The K3 has RF chokes in the ground leads of
the RS-232 port, the ACC port and the mic return. This results in common
mode noise if the ground ring of the Foster mic connector is not tight and
the KIO3 board is not seated properly. The polling noise is particularly
significant if the rear panel (3.2mm) mic input is used because there is NO
chassis ground on that jack other than through the RF choke.
Check all your grounds! With the K3 it will help to add jumpers
between the ground/common pins of the DB9 (RS-232 - pin 5), DB15HD (ACC -
pins 5 & 12) and Foster (Mic - pins 7 and 8) connectors and the shell of
the connector. This allows the "ground" currents to reach the chassis
directly rather than see approximately 4 Ohms in the common leads.
Echo when doing SSB
Playback Line In control being un-muted (audio mixer). the computer is
almost certainly echoing Line > In to Line Out. Right click on the
task bar speaker Icon and select "open Volume Control." Select

that channel is muted (note Line IN may be identified by the
color of its jack). Update Router's presets so the Line In is
always muted on the playback side. microKEYER does not have any
ability to connect Line In to Line Out.

either press the keypad number to be programmed (0 thru 9) or rotate
VFO A for memories 10 and upwards to select the number you want and
then press V-M again.
With CAT noise in the Icom transceivers, check the ground connection on the
"Remote" jack in the transceiver and on the shell of the "Remote" plug of
the transceiver interface cable. There have been several reports in which
the ground trace on the CAT (remote) has been opened. If the CAT return
is open, CAT data will return through the ground lead of the ACC jack
and can effect the "line" input which seems to be always on in Icom radios
except the IC-7800.

Kenwood radios you need to be aware of operating frequency and the
"Digital Band Map." If the "Voice/Digital" box is set to "by
frequency," audio and PTT settings will be set to either the Voice or
FSK/Digital settings based on the operating frequency (Digital Band
Map). In addition, most Kenwood transceivers require PTT_2 on
digital (ACC jack audio input) and PTT_1 for Voice (Mic connector).
Audio Routing C and A are appropriate with PTT_1. Audio Routing B
generally requires PTT_2 which mutes the microphone.
All other Radios
The cat data reports are also more common among
those users with non-Icom (dynamic) microphones as they generally run much
higher "mic gain" levels which increases sensitivity at the line in.
Logger will not record QSOs with MK2R+ because its
recording function can not be assigned to any soundcard other
than the one being used for DVK (USB Voice CODEC in MK2R+).
The only way to record contest audio with N1M Logger and MK2R+ (or a
second soundcard) is to use separate software (like RecALL) to do a
continuous recording of USB Audio CODEC or the second soundcard.
recording in that case will depend on the transceiver.
Some transceivers had both receive and monitor audio on their
"Line Out" others only have receiver audio. Some have only main rx
audio; some have mixed audio; some have dual audio.
would still need to use a separate application since N1MM Logger can't
select an input on any card except the one being used for the mic
input/output since it manipulates the hardware mute/select controls and
virtual audio cables can't create inputs that are not physically
present. In fact, most VACs behave exactly link the USB Voice CODEC in
MK2R+ - they are a single input/output device.
expects a line input on a single soundcard. MK2R+ has two soundcards -
one for the mic/DVK and one for digital modes (Line In/Line Out).
solution has always been to allow the user to specify an arbitrary
soundcard for the "record QSOs" function. It would also help those with
"simple" soundcards that
lack separate mic and line inputs but so far the N1MM development team have not made that change.
N1MM soundcard optionsNormally
if you are using option 1 or 2 for a single sound card and one or two
radios you would put the radio line-out to the sound card line-in and
select line-in for the radio input port. The input line would be the
microphone as would the line to mute, then plug the mic into the
microphone input so you can record messages on the fly. N1mm will
automatically switch from recording qso's on the line-in to recording
from the microphone when you do ctrl-shift-fx.
The problem comes
when you try options 3 or 4, while I think the ocx could handle
recording and so2r switching at the same time there could be some
confusion about what is being recorded. It can only handle recording
from one source at a time, so it couldn't record from the line-in for
one radio and the cd-player input for the other at the same time.... so
that is why I suspect the radio input port is grayed out for those
options... but apparently the record qso's capability wasn't turned off
and is conflicting with something.
Realtek sound card drivers and MK2R+'s USB Voice
One soundcards installed (only Realtek)
This screenshot file explains how to get around a problem
caused by some Realtek sound card drivers (used for Realtek and some
Soundmax cards and onboard audio components) when trying to use the
MK2R+'s USB Voice CODEC. I know this sounds nuts (after all,
the MK2R+ uses its own sound cards, right?), but bear with me.
Certain sound cards and motherboard sound card components made by
Realtek and Soundmax (which uses the Realtek drivers) prevent proper
operation of features such as on-the-fly recording of DVK
messages. There's a lot of magic here about ID numbers and
such, but instead of getting into that, here are some easy step-by-step
screenshots to get you going.
If you have this problem, the usual symptom is that N1MM will record an
empty file when you try to record with Ctrl+Shift+Fx.
First, in N1MM logger, go to the Audio tab in Config|Ports,other
Select the USB Voice CODEC as the Device. The only inputs it has are
Microphone. Don't worry about the Radio Input Port -
N1MM can't currently record QSOs with the Audio CODEC anyhow. Just set
it up like this.
Now open Windows Control Panel, and select the Sounds and Audio Devices
Click on the Audio tab first. Set the USB Voice CODEC as the Default
device for BOTH playback and
Recording, and click Apply, then OK out. Now click the Sounds tab.
Normally, the Sound scheme will be identified as Windows Default, but
if you leave it alone, the Windows sounds (like the File not found
"clunk", for example) may wind up in your recordings or
even go out over the air. To prevent that, you need to create a new
scheme. Starting from the Windows default scheme you
select each sound in turn from the Program events list, and assign
"None" to it. Then save the resulting scheme under
the No Sounds title. Apply it and OK out.
Now go back into the Router, and make sure that the Audio
tab has CmCmCm set for Voice, and that the left channel is selected for radio 1.
That's all there is to it. Now when you record DVK messages on
fly (by pressing Ctrl+Shift+Fx), your microphone audio will
reach the Voice CODEC, and playback will work normally as well.
Probably the best place to monitor your voice level is
on the Audio Mixer tab of Router, in the left-hand bargraph. It has
much more "resolution" than the simple indicator provided in the
Info window of N1MM Logger. Enjoy!

Ok I have the realtek problem
on the software you are using to record the mic audio, Wave In ID
<> Wave Out ID can be a real problem. You have set the default
recording device to the microHAM CODEC and the default playback device
to something else. The Mixer is still somewhereelse and most amateur software can not handle that condition.
Ok I have more than 3 mixers
Windows XP mixer (SoundRec32.exe) only accepts mixers 0-3 on the
command line (the way Router calls the TX or RX mixer). When you have
at least four soundcards (five Mixers) in your system and microHAM
CODEC is the fourth or fifth mixer, it can not becalled directly with the TX Mixer or RX Mixer button.
Two soundcards installed (disable Realtek and use the other..)The issue with the RealTek HD Audio
system is that RealTek creates two separate mixers: RealTek HD Audio
Input and RealTek HD Audio Output.
Windows assigns the Audio
Output as Mixer 0 (Windows Default) and Audio Input as Mixer 1. This
results in a mismatch between the Wave In ID, Wave Out ID and Mixer ID
for not only other soundcards but also the Wave Out device. For example
a system with RealTek HD on the motherboard, Sound-Blaster Audigy 2 ZS,
microHAM microKEYER II and microHAM MK2R+ looks like this under Windows
XP (my own "testbed" system):
ID Wave Out Wave In Mixer
0 RealTek HD Out RealTek HD In RealTek HD output
1 SB Audigy 2 ZS Audigy 2 ZS RealTek HD input
2 USB Voice CODEC USB Voice CODEC Audigy 2 ZS
3 microHAM CODEC microHAM CODEC USB Voice CODEC
4 USB Audio CODEC USB Audio CODEC microHAM CODEC
5 n/a n/a USB Audio CODEC
is possible to force "normal" behavior by defining the desired
soundcard as the Windows Default (with all the issues of "Windows
sounds" impacting the radio and other software screwing with the audio
settings). However, with a RealTek sound device installed, the HD Input
Mixer will almost always take up the "Mixer ID 1" position and every
device other than the default will be impacted by the Wave/Mixer
N1MM Logger addresses the Wave In and Wave Out
devices based on the Mixer ID. In the system documented above, setting
N1MM Logger to use the microHAM microKEYER II (microHAM CODEC) results
in an attempt to use the output and input devices attached to the "USB
Audio CODEC" (the digital/recording input of microHAM MK2R+).
Attempting to "cheat" by telling N1MM Logger to use "USB Voice CODEC"
also fails because USB Voice CODEC has no "Line" input.
will function in this environment because it addresses all of the
systems inputs and outputs individually rather than through the mixer.
when having two sound cards (Realtek onmotherboard) disable the Realtek
in the motherboard BIOS. Use the other soundacrd installed and make it
Default." You can then allow Windows to access the
default card without impacting "microHAM CODEC" and N1MM Logger should
not have any problems selecting inputs since the Mixer ID will point to
the correct end-points. This is exactly what I would do to prepare my
test system for daily use (I leave the ReaTek enabled for
This situation is not restricted to
systems with RealTek hardware. It sometimes occurs with old modems that
support telephone answering/recording capabilities; they often install
just an audio output but rely on the soundcard fortheir input. The
Mixer/Wave mismatch also occurs in systems where the user has installed
a USB Audio output only device like some of the digital audio playback
"dongles." Those devices install output mixers but no input mixer.
