Icom 7300 DM780 Setup For PSK31, RTTY and CW

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.

I’m having a lot of trouble getting my IC7300 and HRD 6.4/DM780 to transmit in CW mode. I’ve been following the instructions I’ve found here and on other sites, but it doesn’t seem to work. I’ve got both the regular USB cable and a Valley Enterprises (FTDI chipset) cable hooked up between my Lenovo T430 and my rig. (The CI-V cable is in the Remote port on the back of the rig, if that helps.) When I’m in DM780 and in CW mode, I hit the Auto button and the rig goes into TX mode, but it doesn’t actually transmit anything.

My USB cable is COM3 and my FTDI cable is COM4.

I had all this set up and working fine with PSK31, but I just can’t get it to work with CW, which is why I bought the second (FDTI) cable, based on all the information I’d seen online.

I’m almost tempted to reset the rig to factory defaults and start over, just in case I’ve got something else configured wrong, but I haven’t gotten to that point yet.

Thanks.

Thank’s for a great article.
I had some trouble with my home-made CI-V cable until I realized it needed its own USB driver (PL2303).
Also encountered a problem when DM-780 started the transistor in TX mode, but it was permanently fixed by clicking start and stop (F4 and F5) in the program.
I’m 80+ and my CW has become somewhat rusty. Now a new world is open to me.

Hi Rich
I have spent most of the days communicating with PD9FER, Ferri at HRD support (he sends his regards).
As mentioned earlier, I had problems with my IC-7300 going to TX when I started HRD.
Ferry have hunted this problem and found a simple but amazing solution.
The solution was to uncheck RTS in HRD Preset (all boxes unchecked).
The amazing part was that I could send real CW without a CV-I cable (?).
With the rig in CW mode and the DM780 in CW (KY Cmd), my IC-7300 sent gorgeous CW signals and the rigs KEY SPEED and CW PITCH can control the signals.
Ferri assures me that I send CW and not MCW but I don’t know any way to check it, do you? If this is correct, I can’t quite see why one should use a CV-I cable in addition to the USB cable.

Hi Rich,

I m stuck! I m running HRD latest version with the two cables connected to the radio everything went very easy thanks to your videos. I can send CW no issues but when changing to RTTY FSK I get solid career signal but no warbling? I have check and check all steps and no joy yet, I’m sure is me doing something wrong or missing some check mark just can’t pin the issue? Please advise.

Hi Rich,

Just got an IC-7300 recently and I am trying to get the two cable approach to work. I am missing something I think. Every time I connect the data controller the rig goes into transmit and stays in transmit. Pause and stop are grayed out. I know it has to be a setting somewhere. I am using a RigTalk for ICOM CI-V to interface the C-IV remote control jack to my PC. Any thoughts??

Best Regards,

Hello Rich,
I just purchased the IC-7300 and I am trying to do CW on DM 780. I have followed all of the above steps with respect to the drivers for the 7300, HRD, and the CI-V and USB cables. HRD connect fine and reads my radio. However, in DM780 when I try to send CQ, I get the following error message:
“Error opening COM8 to send CW – Access denied.” I have the same CI-V cable with the green and red lights. Both blink. Any thoughts?
Thank you for your time.

Hello Rich,
I just tried that and it still does not work. HRD is using CI-V (COM8 on my computer) and DM780 is using the USB (COM7). However, when I try to send CW it still gives me the same error message. For some reason it wants to default to COM8.

Best,
John

Hello Rich,
I got it to work! Actually, COM8 was still selected under Program Options > Modes + IDs. So, I changed it to COM7, checked DTR and it worked. Thank you for your advise and swift help. I’ll be using my 7300 for the California QSO Party (CQP) this weekend. We’ll be using the call NK6M. Stop by if you have the time 😉

Good videos but I am told that I do not need a CI-V cable. Now that has me totally confused. Can you explain in layman’s terms what the CI-V cable does and if I do not use it why would I need a virtual com port?? Hoping you can help.

Hi Rich. I’m following all your video instruction and things are going well. I wonder if you could do a summary of your current best settings for the 7300 and HRD/DM780/WSJT-X? I have followed the settings over the years and they seem to have evolved. I, like you, would prefer to have radio settings that don’t change from mode to mode.

Also, I am using the two cable setup but dont use FSK so are two needed or better?

So what is current best practice? Thanks. Scott KI5AWX

Thanks for the reply Rich.

Currently I have settled on operating WSJT-X without HRD because HRD was causing my radio to switch from USB-D to USB after every xmission and again at the beginning of a transmission if I changed it back to USB-D between xmissions!!

So that’s what works for me. I am using two cables because that’s the way I first set it up and if it ain’t broke don’t fix it. I think I’m done setting up WSJT-X.

Hi All-

Was having same issues as above and HRD supplied me with the proper settings for both HRD and the 7300. Check them out below. Don’t forget that if you use the F2 Auto button in HRD, you’ll need to have Break-in enabled on the rig.

In your radio set:

USB SEND to OFF
USB KEYING (CW) to DTR
USB KEYING (RTTY) to RTS

Use the DTR value in the Modes & ID’s > CW page, do the same for the RTTY page, but select RTS (and the correct com port)

To operate CW you need to toggle Break-in in your Radio and set the radio in CW mode (not Data)
To operate RTTY your radio must be in RTTY Mode (not Data).

Hello – I do have RTTY FSK working w/RTS. I’m using the USB interface with VSPE connected to Win4Icom. The Win4Icom team does not advise using VSPE as their rig control program will not handle a radio command from another source.

Is there any way to connect RTTY FSK while using USB interface for rig control? It’s not possible to use CI-V for rig control since it does not support the baud rate needed for spectrum scope display.

Hi Rich – Yes, VSPE does work as far as I can tell. I discussed with support at Win4Icom and he stated that the problem is if another application attempts to control the radio on the same port. Win4Icome will not handle that…. I observed this by trying to run N1MM+ on the VSPE serial port; sure enough Win4Icom did not like that (fatal error).

Hi Rich – Yes, Win4Icom supports N1MM+ on the same usb port. You need to add virtual serial port and then set N1MM+ up to use that port. Win4Icom Setting – 3rd Party SW/HW tab and add it there. works very well! I’ll send you an email with more details as comment size limited.
