Group,
Thanks to Dean, Joe and Steve (GW4BLE) I determined that I had to go
into the windows sound system and select the 2 channel option as
described below. Both instances of MMTTY are now receiving the proper
signal and demodulating correctly.
Now on to the transmit issue which I'll tackle this evening. I have a
sneaking suspicion that it has to do with the way I have my com ports
setup. I'll report back when I get it resolved.
After I get all of this working, I'll look at installing OCX
Thanks

Welcome to the twilight zone. Been there. Many times.
To see the way the sound cards are set-up within your system - click
on the Audio-switching tab of MK2R+. then click on "soundcard" - over
on the right 2/3 down the window.
Even though the MMTTY plugin works, I would suggest that it might be a
good idea to actually use the "OCX" set-up guideline as this is a more
modern driver with the possibility of also using "2tone" as an
alternative to MMTTY.
if you're setting audio from the left channel in both windows - 1st
make sure the buttons on MK2R+ are set correctly. That's the top right
section of MK2R. If that is correct then you need to go to windows
sound system - right click on the "speaker logo" in the system tray.
Choose recording devices. in the recording devices double-click the
USB codec. Then choose "advanced" tab - extreme right top of the new
window. You will then see a drop-down with "default format" - this is
where you need to choose a stereo option. Your current default is
probably a mono option.
I choose 2 channel, 16 bit 44100Hz (CD Quality) and this has always
worked for me but I am almost sure it can be a much much lower quality
- others with more expertise may jump in and help with guidance here.
Finally after clicking the necessary "OK" etc. return to the two MMTTY
windows and just confirm that left channel has been set up for your
radio 1 and right channel for your radio 2.
Hmmm... you may also want to go back to router as well and under audio
switching tab re-confirm that the "use line out channel" has also been
set for radio one and radio 2. both may be set as "left".
you should now be good to go as far as dual receive.
let's get that going and then check the tx side of the equation.
73 and best regards,

This is a cross post to Writelog and Microham.
I've been working on configuring an MK2R+ SO2R controller with a
pair of K3's and my Win 7 Pro computer.
I've been able to get SSB and CW to work properly.
I'm hung up on RTTY using MMTTY. I've downloaded the setup guide
from Microham and have setup two directories and two instances of
MMTTY, I also have the MMTTY plug in for Writelog installed.
If I select the test button for FSK on the MK2R+ ports tab for rig
1 I get diddling same goes for rig 2.
While in Writelog I've followed the setup instructions by first
selecting rig 1 and starting MMTTY from the appropriate directory,
same for rig 2. However, I can't get either to diddle.
In addition, both instances of MMTTY appear to be getting the same
audio from rig 1 from the phone jack. I've selected the right and
left audio source on the misc tab while in TNC setup.
On the sound card tab in TNC setup I've selected Reception:
Microphone (3 - USB Audio CODEC) and Transmission: Speakers (3 -
USB Audio CODEC)
How does one determine which device identifier to select on the
misc tab in tnc setup? I thought it would be 3 but I'm obviously
incorrect. I want to to use the line out on the rear of the K3's
to grab the audio since it's fixed and won't be affected by the
volume control of either K3.
The frustrating part is that I had this MK2R+ working just fine on
RTTY with one K3, adding the 2nd K3 has been a challenge. Is
there an updated setup guide specifically for Win 7?
I'm half tempted to dust off an XP Pro laptop and give that a try,
Win 7 makes things very challenging.
Thanks in advance for any assistance.
