N1MM Logger+ Spectrum Monitor

Have you seen the N1MM Logger+ Spectrum Monitor? Not too long ago N1MM came out with a spectrum monitor for a limited number of radios. Fortunately the IC-7300 is included in the list of supported radios. The N1MM Logger+ Spectrum Monitor, sometimes called Spectrum Display, is a nice addition to N1MM Logger Plus and it works very well as I discovered during a RTTY contest.

Even if you don't contest N1MM Logger+ can be used as a general logger. I like using it and MMTTY for RTTY (FSK).

Icom 7300 Menu Settings for N1MM Logger+ Spectrum Monitor

I try to keep it consistent and the Icom 7300 menu settings stay pretty much the same. So whether you are using one cable or two, these will work.

BTW, for this setup I am only using the USB cable. Here are some screen shots of the Icom 7300 menu settings under MENU>SET>Connectors.

If you ever have a question about this or if it's not working for you, please shoot me an e-mal or comment below.

2. Windows 10 Pro device manager and COM port properties
3. N1MM Logger and Configure ports.
4. Spectrum Monitor and various settings.
5. I forgot, but hold down the Ctrl key while clicking in the waterfall and it will put you in SPLIT mode!

I hope you find this informative and useful. Please comment below. Best 73 and good DX. - Rich, K0PIR

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

Hi Rich,
Thanks for the answer!
“Window->Digital Interface” really works ).
But I mean a little different: I have only 2 modes columns (with the bands) at the main N1MM window – CW, PH.
And CW, PH, RTTY, PSK are on the video.
How can I get at least RTTY? )))

Dear friend, I bought an ICOM 7610, my English is very weak, I watched the videos you posted here via YOUTUBE. Even though I’ve seen your video several times, I still can’t set it up. So that it’s communicative together, I mean MMTTY who walks me alone (MMTTY) but not with N1MM. Also N1MM + FL DIGI, and logger 32 also doesn’t work with support (cabel usb1)
It’s stuck there. Please send a more detailed setting manual within (FSK) -RTTY, FL DIGI in some way.
Thank you for any help 73! Petr OK1MGA Czech Republic
my email is petr@ok1mga.com
PS:Your videos are nice and instructive, I try to get information there leading to a successful setup, but I’m not doing well yet.
