Setup guide

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 PTT.
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 configuration).
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.
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 fly."
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.
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 application.
Q. Which sound card driver to select in Windows
A. 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 the air!
