Icom 7300 N1MM Logger Plus Setup


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.

Hello Richard

i see several of your videos about ic7300
i am using on 1er computer (windows XP)DX4WIN+MTTY and MMTTY+N1MM WITH MY IC756PRO3
i had no problem with MMTTY + DX4WIN or mmtty+N1MM on FSK mode
I have the 2sd PC with WIN7 PRO
like you i am using two port one for CI-V and other for rx tx cw
with my trx IC7300 i am enable to made FSK
i read several of your video but no fsk here
when i use MMTTY only is ok on fsk mode
but when i am using it with DX4WIN or N1MM on RTTY MODE FSK have only a tune
Tnx for reading my message

Do I understand that if you want to do CW keying with n1mm logger you need the CI-V cable? Or is the CI-V cable Just for cat control or the USB cable for CW keying?

Rich, I found the same thing with the cable in the link you provided. I bought an FTDI version and it’s fine. I’ve been through a lot of discussion on the N1MM group on groups.io–the consensus–or at least loudest–opinion seems to be that the CI-V cable is superfluous at best. I have CW working withou it (just the USB cable).

What is your rationale for the 2-cable setup?

Hi Richard Ive followed your directions to get N1MM up and running unfortunately when in cw mode my radio puts a continuous cw signal that cannot be switched out from the radio controls any suggestions would be appreciated.
Many thanks for all your posts they very useful especially for new IC7300 owners

Is it possible to use the spectrum scope in n1mm, using a usb cable and ci-v cable on a IC-7300 in rtty mode?

If so, how do you setup everything? I’ve saw several youtube videos on the IC-7300 and n1mm but nothing on the above question.

I’m curious about the details of how you have the CI-V cable connected between the IC-7300 and your computer. Are you connecting the IC-7300 remote jack directly to a USB port on your computer, or are you using an interface device such as the Icom CT-17?

I was able to get MMTTY working using FSK, but am now working on getting N1MM Logger+ working as well.

Thank you!

I will definitely give the VSPE software a try. I also have a second monitor that could be hooked up just to show the N1MM spectrum display.

Thanks again!

Got VSPE installed and have N1MM Logger+ working with MMTTY now with the full screen spectrum display. Will try to find some time to make a few contacts later this week.

How do you “pair” a virtual port with the physical port that is installed by Icom drivers My software is VSPM, it is easy to create virtual ports and pair them but , for example, if the Icom 7610 or 7300 is on Com Port 6 and you want a SECOND application to share frequency read out, how do you do this? Example Commander and CW Skimmer (Omni Rig) both communicating frequency info to/from the ICOM ?

Can I use this logging software “together” with my Icom RSBA1 software?

Hallo Rich ,
ich habe den IC7300 und N1MM Logger in Betrieb . Dazu ist ddie USB Schnittstelle mit wsjT-X beschalten . Die QRG wird über die Remote Schnittstelle übertragen . Hier ist auch FSK CW installiert .
Nun möchte ich aber die QRG auch noch in meiner PA Auswerten für die Bandumschaltung .
Dazu brauch ich aber eine CI-V Schnittstelle ..
Hier liegt aber mein Problem … Eine weitere VI-V Schnittstelle ! ???

Allow me to help with Udo’s post – It reads:
Hi rich
I have the IC7300 and N1MM logger in operation. For this purpose, the USB interface is wired with wsjT-X. The QRG is transmitted via the remote interface. FSK CW is also installed here.
Now I would also like to use the QRG in my PA for band switching.
For this I need a CI-V interface ..
But here is my problem … Another VI-V interface! ???

Would love your thoughts, please comment.x
