Get the drivers from the Icom website.
After installing the drivers, connect the USB cable. There will be 4 devices
created:
* The first COM port will be for CAT. Point N1MM+ to it as (probably) Radio 2
(after you enable SO2R), with the recommended settings. PTT via CAT.
* The second COM port will be for "data" (think it's for DSTAR work; not
relevant to N1MM+)
* One "USB Speakers", which is for AFSK/soundcard digital output
* One "USB Microphone", which will receive audio from the 7100
Configure whatever combination of MMTTY and 2Tone you use to use those new
sound devices.
The 7100 is capable of FSK, but you need a separate interface to achieve that.
If you do AFSK... the last time I checked N1MM+ wasn't handling the 7100 quite
right.
For AFSK, configure N1MM+ to set mode=LSB for RTTY. You will have to manually
tell the 7100 to enable LSB-D (pay attention to that each time you do a band
change). Also, you'll have to manually configure the 7100 to accept audio from
the USB port (Set > Connectors > DATA MOD > USB).
The DATA MOD setting is not sticky, by the way; you will probably have to reset
it after each power cycle. There is a request to get this changed in N1MM+ in
the queue, but (the last time I checked) it's not percolated up yet. (I think
I'm one of the few 7100 users who have been given the development team input.)
You'll also want to spend some time configuring the filters on the 7100 for
AFSK work. For that, the manual does a better job explaining than I can.
And, if you try it AFSK, remember to watch your audio levels, and don't forget
that the 7100 isn't designed to be key-down at full power for significant
lengths of time.

Subject: [RTTY] ic-7100
I'm getting more confused. My main radio is a Flex 5000 and I have successfully
connected it to N1MM so I'm not a total neophyte at this but I'm still not
sure how to proceed. I was wanting to add the 7100 as a second radio in order
to try some SO2R.
I never tried connecting the USB cable as I thought there was no way to
interface USB to N1MM directly. But a friend of mine suggested that maybe once
I do connect via USB that a new COM port will appear and then I can interface
with N1MM. I'm going to try that this afternoon.
My intent was to use FSK and I have already tested that part of the connection.
It is the CAT functions I can't figure out.
Jim's post really has me confused. Jim, if you have time, could you please
contact me off list and tell me how you have your radios set up?
I guess I don't understand about the internal sound card. I knew the radio can
decode RTTY directly but how does 2Tone process the audio if the soundcard is
inside the radio?
Thanks,
Mark K5XH
