Icom 7610 N1MM One Cable RTTY FSK CW – How To

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 Richard and the group

Am I reading this correctly, that I no longer need any type of interface???
Right now I use a home brew level converter that’s worked perfectly with my Icom IC-7600.
The 4 programs I use are N1MM, DX Labs including winwabbler and WSJT-X along with JTAlert

I do want to use true FSK

Hi Rich

OK on N1MM, I do have rig control, radio receives rtty ok, radio does go to transmit when a macro is pushed but no dittles. any ideas with that

With DX Labs commander, nothing, no rig control at all

Would you be available for a team viewer session???/

Hi Rich

More progress made today, in N1MM I do have dittles and it does key the radio, I have no power out on the radio, Am I missing a setting

On DX Labs I do have rig control but no power out on RTTY also.

What am I missing here????

Thank you in advance for your help

Yes radio is in RTTY mode
with power at 100% I have no power output
The scope shows that it is transmitting
Power meter =0
SWR meter =0

Hi Rich,
Just opened my new IC-7610 and watched all your videos.
I am experienced for 2 years with IC-7300.
In your video you say:
“As a prerequisite, always install the Icom 7610 USB driver before connecting the USB cable”
I cannot find nowhere this f… driver
When I connected the USB cable, my device manager reports COM6 & COM7 (in your video is 4 & 5).
Do I need a driver?
The MMTTY does not make TX on the transceiver.
The whole setup is OK.
Please for any kind of answer…Thanks Alex SV2BXA

Does the 7610 provide on screen decoding of CW?

I used your video to setup my new 7610 and N1MM but now the 7610 goes into Transmit mode after about 5 seconds after power up and no matter what I have tried I can’t get it to stop other than powering get down. It was something in the setup because it worked fine before I started making the changes you suggested in the 7610 to use with N1MM. I really don’t want to do a factory reset to lose all of my settings on the 7610 but I may have to. It is now unusable. Help!

My version of mmtty does not have EXTFSK64 only EXTFSK. I assume that EXTFSK will work ok or do I have to download the EXTFSK64.

Rich,

I gave up Win4IcomSuite. It’s radio control screen is much better than HRD but I would rather use the radio itself. Much more fun. I see what you mean. Win4IcomSuite ties up the first com port (A) for rig control when you can use a Ci-V cable with HRD. Win4Icom does not support CI-V.

Followed all your steps screen by screen, field by field and have N1NM working with MMTTY now. I was never able to get it to work with my Yaesu FTDX 5000.

Thanks a bunch. I really appreciate the videos.

So what are we going to do with that second blue USB port on the back of the rig?

I tried DM780 FSK, it modulates a RTTY signal but it sounds funny. Not sure if I should run reverse or not. Have not made any contacts but it is early afternoon Sunday and the bands are quiet.

I once say a video that said the waterfall has to be set at 2120 or something close to work????

CW did work.

I made a DM780 RTTY FSX qso. The waterfall has to be set at 2210 and it stays there. You tune using the VFO, not via the waterfall because the 2210 waterfall setting will change. Yes, “Reverse” on because all of HRD’s apps are USB upper and RTTY is lower.

Rich,

I thought I posted this comment already so my apologies if it shows twice. I was able to male a RTTY FSK QSO using DM780. The trick is setting the water fall to 2210 and tuning with the VFO. Yes, the reverse button needs to be on because all DM780 programs are written for USB.

Thanks,

Brad

Yes, it sounded good to me, especially after I made a contact.

Do other programs like Fldigi allow clicking on a waterfall or do you tune the VFO like DM780?

I setup MMTTY to work standalone. I found that I had to change the USB Send menu such that USB-1 B is set to RTS to get MMTTY to modulate. Your video had it set to USB-1 A to RTS.

I don’t understand how you got N1NM and MMTTY to modulate because extfsk64 offers settings for just one com port. In my case port 7. I think it is 5 for you.

Want to make sure I understand.
One cable does both FSK Keying AND rig control?
