Icom 7300 Easy Transmitter Settings For Digital Operation
Let me mention at the onset, there are many different approaches to doing this. This is a basic tutorial, simple and easy. Follow this and you won’t have any complaints about having a wide signal or using too much power.
If you have a suggestion(s), please feel free to comment below.
On the Icom 7300 we use USB-D for digital operation. It can be a little tricky at first getting in and out of this mode. Experiment some and you’ll see how it works. If you are in USB mode it’s very easy. To set: Tap the USB button on the LCD with your finger and when the “MODE” menu comes up, tap the DATA button.
In digital operation there has always been the issue of ALC causing poor signal quality. With the Icom 7300 it is less of an issue. I’ve found that I don’t have any ALC deflection most of the time and when I do, it isn’t a bad thing with this transceiver. For more information on this see Page 4-31 of the full manual. It states, “When operating in the SSB data mode, adjust the device’s output level within the ALC zone.”
Some more information on this exists at AB4OJ.com. There is no ambiguity in what he says. Good read!
Icom 7300 RF POWER
Back in the days of Windows 95 and my old Kenwood transceiver I didn’t set my output power on the radio to 100% or 100 watts. I was too scared of it, but I haven’t had any problems using the Icom 7300 and I’ve used Windows 7,10, MacOS, and Linux. I set the RF POWER on the radio to 100%. To set: Push in the MULTI knob on the radio. Tap RF POWER with your finger, using the MULTI knob again, turn it and and set RF POWER to 100%. Chances are you already have it there.
Icom 7300 Internal Menu Transmitter Settings
Under MENU>SET>Connectors there is an important transmitter setting, but let me mention a receiver setting first.
ACC/USB AF Output Level controls the amount of audio the Icom 7300 sends to your software. Mine is set to 50%. Turn it up too high and the waterfall in DM780 will have too much noise. Turn it down too low and you will have a dark waterfall. It’s worth experimenting with. When adjusting, look at your DM780 waterfall and adjust the level up or down. There is a short delay for the adjustment to appear in the waterfall. You won’t notice it as much in the WSJT-X waterfall, but you’ll see a difference in the receiver level meter in the bottom left hand corner.
USB MOD Level: This is important to your power output and having it too high will cause problems (possibly too much ALC). Too low and you won’t have any power output. Mine is 40%.
The other settings under “Connectors” will be in the video.
Operating System And Transmitter Settings
In the video below I’m using Windows 10 Pro. I almost always use two cables, a CI-V cable for rig control and a USB cable for the digital modes. However, this is not important here because we are mainly dealing with the USB cable, USB Audio CODEC and digital mode operation (audio to and from the 7300).
In Windows 10 “Playback devices” the USB Audio CODEC controls the amount of audio going to the Icom 7300. This is similar to the USB MOD Level in the radio. Too high, it’ll be a problem and too low, you won’t have power output. Mine is 40.
Let me mention “Recording devices” here also and the USB Audio CODEC. “Recording devices” controls the audio coming from the Icom 7300 to your software. This is similar to the ACC/USB AF Output Level in the radio. Set it too high, your waterfall will have too much noise, too low and it’ll be a dark waterfall. Mine is set to 40.
Ham Radio Software For Digital Operation
In the video below there are a couple of examples, WSJT-X and DM780. Setting the power output is fast and simple using just the power slider.
So, if I’m using PSK31 and have my power at 20 watts and I’m not making any contacts, it’s very easy to move the slider up and increase power to 30 watts. There is a great example of this in the video.
thanx for you you tube videos. Still having problems with my 7300 staying keyed, would appreciate suggestions. Using the pi and 7300.
I have used the Pi with Fldigi and WSJT-X. I may have had a problem with keying in the beginning and usually it is an issue with RTS or DTR. Have a look at my radio settings here:
Note USB SEND is RTS.
DATA MOD is USB.
DATA OFF MOD is MIC,ACC
Here are all of them: https://k0pir.us/files/7300screenshots/
See if checking or unchecking RTS in the software has any effect too.
I am NOT seeing the USB codecs at all when I try to set up WJST for the FT 8 mode ?
Do I need to do ANOTHER USB driver download to get these ?
Every thing was working just fine until i did the 1.20 firmware update to my icom 7300 ?
THANKS in advance for ANY help to my problem!
Steve / N7DPX / Lakeside,AZ.
Thanks for commenting. Sounds strange and I haven’t heard firmware causing that problem. If you were using it before, another download shouldn’t be necessary.
How about in Device Manager, do you see the USB Audio CODEC under Audio inputs and outputs? If it’s there, then maybe it’s just WSJT-X not seeing it.
P.S. Restarting Windows may be called for 🙂
Hello OMs .. i have the same problem .. any solution ?
73 de thomas
Nice to hear from you.
How about in Device Manager, do you see the USB Audio CODEC under Audio inputs and outputs?
Hi Steve –
On the 7300’s “Band Stacking Register”‘s screen there is a “button” “GENE” and a button “F-INP” ??
What do these button do??
Thanks, Wes AI4FH.
That’s a very good question. I’ll bet many, like myself, overlook that GENE button. It’s for general coverage. You could use it for broadcast or shortwave listening.
F-INP is to enter a frequency. You can set the frequency without rotating MAIN DIAL by directly entering it on the keypad.
Band stacking and the Memo pad are two good tools to use.
Thanks for coming by and thank you for commenting.
Merry Christmas and 73’s,
Thanks Rich, very helpful. If setting filter 1 to 3.6 & then selecting usb-D, isn’t that the same as just using USB with filter 1 @ 3.6?
Put the radio in USB-D and then change the FIL settings to 3.6K. That will leave USB alone.
It’s a slight improvement.
This may be in the same realm as Riches question. On 20 meters, the only modes that are available are USB-D and LSB. I just got the 7300 and I’m sure this is operator error but I haven’t found it as yet. Any thoughts?
Thanks in advance! Gary W4BVD
Touch the USB-D on the LCD and then touch DATA. That will put you in USB mode. Is that helpful? I’m not sure I understand the question.
It’s a little confusing at first going between the two.
Thanks Rich. I found the problem. There as a little dot next to the filter indicator. I adjusted the size of the filter and the dot went away and USB came back. HA! Lots to learn. What a fantastic radio.
Thanks so much for your kind help! Merry Christmas to you as well.
my problem is the following, I used the version rc 1 of the program when going to any of the other versions the cat stops working.
I still do not understand why, I’m using an icom 7300 and everything works perfect until I want to update to the next version. In this case 1.8
Hi Rich. I have everything set up ok but have one problem. My 7300 keys but I have no modulated output. It just sits at idle while the pgm shows the text being sent. HELP? HI-HI
Thanks for commenting and do you have DATA MOD set to USB in the radio? Do you have power output set on the radio and in the software?
What software are you using?
I am having the exact same problem as Anonymous above. I’ve gone through your YouTube Videos on setting up the IC-7300 on FT-8. Software up and running. I’m decoding stations, but when I double click on a station calling CQ, no power out from the radio, though the radio is going through the tx sequence. I’ve set up all the connection settings you have listed. I’ve run psk-31 and RTTY for years using my Kenwood TS-440SAT with no problem so don’t think it’s computer problem. Also I’m using SignaLink USB interface with the proper USB codec selected. tnx es 73 Harvey, KM4JA
Hi and thank you for commenting.
That’s the problem. Remove the Signalink, because it isn’t needed with the Icom 7300.
All you need is the USB cable and of course, install the USB driver from Icom before attaching the USB cable to the radio. After that it’s just a matter of setting up the COM port and the USB Audio CODEC for input and output.
The 7300 is the best radio I’ve ever used for digital mode. Up until the 7610 of course 🙂
Question for both transmit and receiving
I see that there are many settings for both xmt and recv. I believe I can handle this but what concerns me is changing back and forth between USB-D and SSB,
Is just changing that function all that is needed or are any of the the other settings also need to be changed too?
Nice to hear from you and that’s a great question.
One of the things I like is when in USB-D I can increase the bandwidth on FIL1 to 3.6k and leave it there and when I go back to USB the FIL1 is still at 3.0k. It doesn’t work for everything, but that is pretty nice.
The things that I normally look at (and usually change) after operating in USB-D mode and then going to SSB are NB, NR, Auto Notch and AGC. Having NB, NR and Auto Notch on while in USB-D just doesn’t work good. You’ll see black splotches the waterfall. Having AGC on slow isn’t good either when using digital modes.
It may seem like a lot at first, but I’m used to it now and it’s easy enough.
I hope this helps.
Thanks for visiting and signing up.
Thanks Rich for the information and your quick reply.
haven’t seen any screen-shot how to set the mic-gain knob on the TRV. Mine is on 35, but not sure if that’s OK.
Thank you and great question. In some older rigs it made a difference.
On the Icom 7300/7610 the mic gain isn’t used in digital modes (USB-D), so it’s okay where it is. When you switch back to SSB (LSB, USB) it will be where you left it.
Hi Rich, just curious, but I have read where some amateurs set the record and playback on the computer to dB and to Zero and you suggest using percentage and about 40% and adjusting from there. What are the advantages of using the one method over the other. I am using percentage as you suggested and am having no problems with my 7300 and WSJT-X and FT8. 73, Ray AA4EZ
Nice to hear from you and great question.
I don’t think there is an advantage, I played around with it and found good settings so that my ALC wasn’t too high and I could control the power output from the slider in my digital software (DM780 and WSJT-X). That’s the only slider I want to be using when operating. All the others I leave alone.
I hope this helps. Thanks for commenting and best 73!
Hello Rich – Your You-Tube videos are a great relief. I am having problems with N1MM+ and MMTTY . I have the two decode windows open, DI1 rX1 2Tone and Rtty engine 1. I am using a laptop and controlling a ICOM 7300. RTTY decodes 100% but I seem to not be able to XMT anything to the 7300. To validate operation between the 7300 and Laptop, I use WSJT-X. The same laptop and 7300 have no problems. Decodes and XMTs FT8 100%. I am using COM 4 with only the USB cable to the 7300.
With N1MM+ and MMTTY I only can receive and decode. Do I need to add a second CI-V cable??? Can N1MM+ and MMTTY be operational with only the USB Cable to the 7300? I am frustrated
Nice to hear from you and those are great questions. I am assuming you want to operate RTTY (FSK)?? Initially, I used two cables for RTTY (FSK) and it is easy in my opinion. However, you can use one cable (USB) and a serial port emulator (VSPE) if you want. The choice is yours.
With N1MM Logger we get the Bandscope Waterfall in the software and that only works with using one cable and something like VSPE. So that may be the best choice for you.
So first, install (VSPE) and get it working. See: https://youtu.be/UtB-DfBMmB0
Then you will want to configure MMTTY and EXTFSK64. See: https://k0pir.us/icom-7300-rtty-fsk-mmtty/
Let me know how it goes.
I have VSPE working as per instructions on the Laptop. However I must have done something incorrectly on configuring MMTTY. However I did find it. First of all since my machine is 32 bit, I had to change config from EXTFSK64 (when set did not show new window) to EXTFSK (window came up okay). Then I could not transmit when port was set to COM4. when I changed it to COM8 all worked. I now have mmtty working as a stand alone. next is to get it working with n1MM
That’s awesome and thanks for posting your solution.
I elected to go to the two cable approach for my 7300, N1MM and MMTTY config. Since my Lenovo T520 has one USB output, I connected a usb hub and have both CI-V and USB cables from the 7300 going to the HUB.
MMTTY by itself controls the 7300 using COM4 in the EXTFSK 1.06 Window. Receive and XMT works fine.
My problem is with N1MM+. When opening N1MM and the radio is set to RTTY, the panel opens up “Contact Mode (RTTY) Contest modes (Mixed). The other windows that are open are: EXTFSK 1.06; RTTY Engine 1; DI-1RTTY Mode – Soundcard (MMTTY) and a beautiful Radio 1 Spectrum Monitor. I can set the Freq via the control panel.
Now that you have all that info, the problem is the EXTFSK 1.06 window. Port setting is COM4 but the status says RED outline with Status NG. I tried to transmit but nothing on the 7300. I set the port to COM3 and Status says OK. I try to transmit and still nothing on the 7300???
What could be set incorrectly ??? with MMTTY running by itself with COM4 in the EXTFSK 1.06 window – all is okay. When N1MM is running – no transmit with either COM3 or 4.
I am stuck – do you have a suggestion?
Good to hear from you again.
With two cables you will not be able to run the spectrum monitor. Close the spectrum monitor and you will have to go in to N1MM Config and verify you have the ports setup correctly. The CI-V is used for rig control, The Icom 7300 will be next to it in the list.
The alternative for N1MM and RTTY (FSK) is to use something like VSPE. With that you can have use of the spectrum monitor. See: https://youtu.be/UtB-DfBMmB0
Thank you again,
using ic7300 and wsjt-x,in ft8-mode,I only can decode the stations,when I send I can here the output and the tx-led lights,but I never get a connect.
Look at the Soundcard under the Audio tab in WSJT-X and see if it is using the USB Audio CODEC for both input and output. Also you can check the radio menu under Connectors, is DATA MOD set to USB? DATA OFF MOD should still be MIC,ACC which is the default.
in your video :Icom 7300 SP RTTY FSK Setup MMTTY N1MM How to” you show your 7300 “connector” page 2/4. What are the correct setting for page 1/4? Top of page is ACC/USB Output Select”
I have all screenshots here:https://k0pir.us/files/7300screenshots/ or https://k0pir.us/icom-7300-wsjt-x/2/
First of all, many tanks for your assistance. I have looked at all screen shots and have set up the 7300 as per instructions. What I am confused is the CI-V cable and the port designation in my Laptop. Going to the device manager I do not see where to set up the port? What I am trying is to set up N3FJP 6.1 and WSJT-X both running with the two cables. N3FJP only shows Com3 and Com 4. Com4 is used with WSJT-X at 115200 Baud.
I cannot poll 7300 with N3FJT Software, Do I need to run VSPE.
The real question is under Device Manager, where do I see the CI-V cable com port
It’s nice to hear from you,
I used the CI-V cable for the N3FJP software and then I used the USB cable for WSJT-X. It sounds like you are trying the same.
Did you install the software driver for your specific CI-V cable? Unplug the CI-V cable from the computer and look at device manager. Make a note of what COM ports are there. Then plug the CI-V cable back into the computer and look at device manager again. You should see an additional COM port.
COM3 is being used for my printer
wow I unplugged CI-V cable and reinstalled. COM8 came up. Thanks
That’s it! If you have the radio setup for Unlink from [REMOTE] in the CI-V menu, you can control the radio from either program. The CI-V Baud Rate is also in the CI-V menu.
Many thanks for your information and videos. You are a great teacher. I now have N3FJT working with JTAlert and WSJT-X and logging. One problem, Mode in N3FJT logs FT8 contacts as SSB. Who and what needs to be notified to log as Digital or FT8. My 7300 is in USB-D mode.
Hello and thank you for commenting.
I know N3FJP will indicate SSB while I am working a contact. It never goes to FT-8, but when a contact is logged it does show up as FT-8 in the log. Have you logged a QSO?
That is strange, I haven’t had that problem. Does WSJT-X prompt you to log the contact? There is a setting in WSJT-X. Go to File>Settings>Reporting. Under Logging check “Prompt me to log QSO”.
When it prompts you, in the prompt window, what does it show for Mode? It should be FT-8.
Got it working fine when I set WSJT-X to prompt me to log contact. It shows FT8 and then changes N3the FJP to proper mode. What thru me was when you click on a CQ, WSJT populates the N3FJT window with call and SSB as mode. Then when you log contact, it modifies Mode when logging. When I do not use WSJT prompt to log, and use N3FJP Log button, N3FJT Logs contact as SSB. When I use WSJT Prompt to log, it logs FT8. Hope this helps
All is working, thanks
FB and thank you for commenting. Great to hear it is working for you. N3FJP is great and I love his other software for Field Day. All of it is easy to use and works good. Glad you got it and 73!
Hi HI Rich, Question about the FT-8. In the waterfall there is a drop down box and you can set it for
current or cumulative. What if any is the difference??
Thanks for the Icom 7300 video’s and I am well pleased with my 7300 as well.
Gerry kd8rfo 73
Hello and thank you for commenting. That’s a very good question. I went by what is on the WSJT-X site and honestly haven’t changed it before now.
From the website:
I’d have to take a closer look, but I see no difference at the moment. I use Cumulative.
I got my 7300 a few days ago, and followed the config directions. I’m only using the USB cable, with FlDigi and WJST-x. Everything seems to work fine. I have rig control, I am receiving audio, but I am not sending audio. I’ve verified that I have the correct sound card chosen, and I’ve triple checked the Icom settings to make sure, but I seem to be missing something.
I’m totally scratching my head here.
Thanks for any input.
I finally figured it out…. I was expecting to see audio on the “S” meter. But when I wen to the Audio meter, it was all there. D’oh!
Sorry I didn’t get the chance to post earlier, I have been out of town.
Glad you got it and I hope it is working well for you. I love it, so simple and reliable once I figured things out.
If you use the MONITOR on the 7300 you can hear the audio output. I find it helpful hearing my transmission at times and watching the power meter.
Thank you for commenting and have a great time.
Hope to hear you on.
I am trying to use wsjt-ft8 with a 7300. I have followed all of the videos and instructions ( i Think) With USB-D and filter 1 at 3.6 selected when transmitting it changes to usb and to filter 2 and remains their until I physically change them back, how do i stop this?. Second question , should I be in linked or unlinked to remote. My cat does not operate in linked to remote ? is this a problem?
Thanks for your help and videos
It’s nice to hear from you.
Look in WSJT-X settings and see if you are using Data/Pkt for Mode. Also look at Split Operation and see if you are using Fake it. I have found that “Fake it” is easier most of the time.
Unlinked is the way to go for most operations and it will work with everything. When N1MM Logger+ (and other programs now) came out with their Spectrum Monitor Display, unlinked is needed.
I hope this helps, let me know.
Your comments fixed me right up. I also found that not using Omnirig for the radio was a help. Thanks a lot for your help and all that you do for the hobby.
Awesome, glad you go it going.
See you on the air!
When using WSJT-X or JTDX my 7300 takes almost 5sec to switch to transmit. I must be missing something. Any suggestions?
Nice to hear from you. Thanks for commenting and thanks for the question.
That is a long time. What are you using for the Rig in WSJT-X?
I am using the WSJT-X program to transmit on FT 8 using my IC 7300. I am able to receive just fine, but when I go to transmit I have no output power. I have configured the settings as you described in your video and have confirmed them with your screen shots. Any idea what I am doing wrong?
Nice to hear from you and thank you for the e-mail.
It is probably just a setting. Did you verify the settings in the radio? DATA MOD = USB
Verify you have selected the USB Audio CODEC for the Audio Soundcard in WSJT-X settings.
What happens when you hit the TEST and the TEST PTT in the WSJT-X Radio tab?
What happens when you hit the Tune button in WSJT-X, does it turn red and do you see the radio key up?
To hear your own signal you need to have MONITOR turned ON in the radio. Otherwise you’ll just see the radio go into TX and not hear anything. You should still see power on the Po scale.
Let me know,
The problem was the power setting was set to low, so when I activated the tune button there was no power output even though the radio would key up. Raised the power level and everything started working.
Fantastic Dave. Glad you got it working and thanks for commenting.
FT8 is a fun mode, hope to hear you on the air!
I downloaded the WSJT-X software and it’s installed on my old HP PC with Linux Mint 18.2 OS.
I updated the firmware to 1.21 today.
Problem is, I’ve been all over the Icom America website and can’t find the driver that you mention in your instructions. I’m using the USB Type A > Type B cable between the rig and the PC.
Is the driver included in the firmware update?
Bob / KD2BOB
Nice to hear from you and it is a little confusing. It has to be read carefully.
See this download link.
It states “Download Type” is USB driver 🙂
At the top it states firmware 🙂
That’s the link though.
I searched on the site for IC-7300 driver and it said no results. So then I decided I might as well update the Firmware and the page had all the receivers and the firmware versions. What I did not see on that page was further down it shows drivers. Different from the page on your link, but still had them.
Now I wonder if I’m going to run into a problem as the driver is only for Windows version, no mention of Linux. 🙁
Still no joy yet. LOL
Thanks for the reply
I contacted Icom tech support and the tech told me they don’t have a driver for Linux. Amazing, as Icom is a global giant and there are millions of people that have Linux as an OS.
I’m going to see if a Linux ham forum can help on this. I hate to go back to Windows to operate SDR. I have Win10 on my dual-bootable desktop and the damn thing gives me nothing but problems.
Will let you know the outcome as I’m sure some of your fans use Linux.
Bob / KD2BOB
Since you are running Linux, just plug the cable into the radio and PC. It should be fine. I used my 7300 and 7610 with my RaspberryPi 3 and it worked perfect.
You’ll see it in there.
Just received my IC73000 and just found your site. Thank you! Problem: whenever WSJT tries to transmit, USB-D shifts to SSB and no transmission. Seems like I saw that question earlier, but can’t find it now.
Nice to hear from you.
In WSJT-X under the Radio tab, set Mode to Data/Pkt and see if that helps.
Thank you! That fixed the “shifting to SSB” problem, but I’m still not there yet. I’ve lost WSJT receive, and it still doesn’t switch the rig to transmit. I’ve gone through all the computer sound settings, and I can see that WSJT is putting out audio when I hit TUNE, but it’s not turning on the rig. TEST CAT indicates all is well. Other settings in WSJT: PTT method is VOX, CONTROL LINES none, MODE data/pkt, SPLIT none, HANDSHAKE none. I am going to go through all your settings recommendations again to see if I’ve missed something. Bob, K5JPB
My PTT is CAT, try that first.
On the lost RX look at the Audio tab and Soundcard settings. Should be USB Audio CODEC.
Step-by-step! Changing to CAT took care of triggering the rig to TRANSMIT, but I have no power out. I had to go into the computer and disable the USB Audio CODECs, and enable USB Audio CODECs (2). Now I have reception, but still no output power. Also, I have to select (from the speaker icon) USB Audio CODEC instead of Realtek in order to get WSJT to use the former. I’m beginning to think the issue is a computer audio one, instead of a rig or software issue, but I’m still going to go over all your settings recommendations. Thank you for your help! I always have my SignaLink to fall back on, but I’d rather do it the 7300 way. Bob
I think you’re on the right track. Are you on Win10?
Yes, W10. After going over your recommendations (late last night), I see a few other settings to try. You’re really helping out the owners of IC 7300s. ICOM shouId be paying you! I’ve seen no other source of detailed instructions for putting the rig directly onto digital modes, although there may be other discussion groups going on. 73, Bob
Great to hear it’s working for you and thank you for the kind comments.
Yep, take it one at a time to see.
I hope to hear you on the air.
Update: turned everything on, intending to make a few settings changes. As usual, I tried everything as is first. OMG it works perfectly! Hmmmmm. Something reset itself overnight. Plan to go ahead and make the changes, one by one, even though the old rule of “don’t fix it if it’s not broken” may apply…. 73, Bob
Thanks for commenting Bob, glad you got it working.
Hope you and your club had a Field Day blast! Thanks to your help, my IC7300 works beautifully on FT8, using WSJT. Using the same rig settings, I can’t get TX to work on PSK on DigiPan. I have the speakers coordinated, and I can receive OK (generally). There don’t seem to be all that many settings on DigiPan, and it has always worked fine with the SignaLink USB. Serial port is NONE. If I change it to COM3, my rig goes to TX until I switch back to NONE. Actually, I don’t use PSK much, but once in a while it’s fun to converse digitally. Any suggestions are welcomed! 73, Bob, K5JPB
Yes FD was a blast! Thank you for the message.
I just tried my 7610 and in the radio USB SEND is set to RTS. In Digipan my Serial Port PTT interface is “RTS as PTT” checked off. It works!
It appears that in Digipan RTS as PTT needs to be checked. That is, if you have USB SEND in the radio set to RTS.
Wow — Thanks again! IC7300 was fine, but needed COM3, RTS. Bob, K%JPB
Follow-up: Set for 75 CLEAN watts with no ALC. First CQ answered by YB8MAN in Indonesia!! Wow. Thank you.
I’m trying to set up IC-7300 to work in Split mode for WSJT-X/FT8. However, when I go through the basic set up procedure from 3-6 and 4-13 of the IC-7300 full manual, I get an error message on FT8 as follows:
Emulated split mode requires rig to be set in simplex mod.”
I switch the IC-7300 Split mode off and things work O.K., but then I’m transmitting on the primary FT8 frequency (40m / 7.074 in my set-up).
Thanks for your thoughts…
Thanks for commenting and it’s nice to hear from you.
I used “Fake it” for split in WSJT-X. It works really well in the 7300. There’s no need to physically put the radio into split mode, the software will take care of it. You won’t see the radio in Split mode.
Try it and you’ll see how it works. When transmitting the software will (sometimes) alter the TX freq. automatically.
Let me know how it works for you.
I’m a fairly new ham, general license, using an IC-7300. By following your instructions I’ve installed WSJT-X (v1.1.1) and can monitor and see signal coming thru in FT8. Test CAT seemed to work, and once Test PTT seemed to work, in that they took over the radio. But then it seemed like the radio was stuck in TX as the TX/RX button was a steady red. I pressed the transmit button to turn off the constant red TX. Should the TX/RX light be a constant red? Also, I seriously doubt I am actually transmitting because I’ve tried to respond to some CQ’s and send some CQ’s, but PSK Reporter says I haven’t been heard from in 20 hours.
Thank you for the question and commenting. Congrats on your license and radio!
Download the latest WSJT-X v1.9.1
If the radio is stuck transmitting, maybe you have RTS set in both the radio and software. In WSJT-X go to file>settings>Radio. Under Force Control Lines make sue RTS is blank. Then try it.
If that doesn’t work go into the radio menu. Menu>Set>Connectors and change USB SEND to OFF. See: https://k0pir.us/icom-ic-7300-specifications-features/icom-7300-screen-captures/ There are some explanations below the screen captures.
That should work.
I’m headed out of town for the Breakfast Club Picnic. Best 73!
Also, somewhere along the line, it reset my AGC to mid when I had it off. WSJT doesn’t shut down nicely and I end up having to reboot my computer to get it back up.
Thanks in advance,
That’s unusual Ellen.
If you are on Facebook, there is a WSJT-X page there.
I would try again. There’s not much to the program and it is a lot of fun to use.
I have set my ICOM per the print screen. Now WSJT wont take control of the rig. Here is the radio configuration from a print screen. Serial port is COM3, which is correct. AF adjusted down to keep me out of the red. 8 data bits, 1 stop bit, NONE Handshake, CAT on COM3, Data PKT and FakeIT set. USB Audio CODEC selected. There was a PATH error in the install. I’ve uninstalled the driver and reinstalled. Uninstalled WSJT-X and reinstalled. I’ve rebooted. At this moment I can decode and see on the monitor, but not transmit as I don’t have control of the rig.
Is this WSJT program worth this frustration? From my point of view, the install and configuration should be easier than this. I’m running Windows 10 Home, version 1803, OS Build 17134.112
Any suggestions? And Thanks in advance.
Do you have another program working, maybe DM780 or Fldigi?
I think WSJT-X is probably the easiest, but I know people sometimes have trouble with it. It’s usually a setting somewhere that causes problems.
Check you baud rate in WSJT-X and in the radio. If you have “Unlinked from Remote” set in the radio the CI-V USB baud rate can be set as high as 115200.
For PTT in WSJT-X there is only CAT, there should not be a com port associated with it.
Looks like everything else is good.
Problem resolved. I had to put ferrite chokes on the USB cable, and disconnect the wireless mouse. Then a miracle occurred and I started to be heard and to get WSO’s. Thank you for your help. A ham on facebook suggested the ferrite and then the world came together.
Awesome! That is absolutely great Ellen.
Hope to hear you on the air!
Hello, I use an ICOM 7300 with a mag loop. However nobody seems to hear my CQ. The TX does switch to transmission (red light and fan starting), and with another receiver I hear a garbled signal. I checked the PC playback device and I have the sound output bar going up. However output level level seems to be constant. Is this normal? USB MOD is at 40%.When I TX the IC7300, it switches from USB-D to USB and stays in USB? Didier
No it should stay in USB-D mode. If you are using WSJT-X or JS8Call use “Fake It” for Split Operation and “Data/Pkt” for Mode. That is under File>Settings>Radio in both apps.
Also check in File>Settings>Audio and see if you have the USB Audio CODEC for Soundcard Input and Output.
I run the IC 7300 mainly Digi Modes. For normal operation I use DXLab and MultiPSK
For contest I run N1MM Logger+. With this latter program the DAT MOD always goes to default ie: ACC it works OK but there is no way I can get it to default to DATA MOD USB. Seems a bit odd, I assume it’s the digital interface with N1MM which is MMVARI.
Any comments appreciated
Nice to hear from you and thank you for commenting. I have not heard of that.
The only program I know of that will make an internal setting change in the radio by its self is RS-BA1.
You are using the USB cable and no accessory connection at all?
There is an Icom 7300 forum in the Groups.io. You may want to ask there. I am not familiar with MMVARI.
I’d be interested to know what others think.
P.S. I’m going to have to try that one.
Hi Rich. I’m having a new problem I can’t solve. I’ve been using WSJT-X for over a year, using my Windows 10 PC (v. 1809) and my IC-7300. I upgraded WSJT-X to v.2.0.17 several weeks ago and it was working. Now, I can’t transmit. I’m using the Silicon Labs CP210x USB to UART on COM3 (Driver: 22.214.171.124 ). I went into the Set Up menu and can’t find the device at all even though I see it in Device Manager. HRD seems to be transmitting fine. I’m stumped. Thanks Rich, AE0L
Nice to hear from you and thank you for commenting here.
When you say you cannot transmit, does it key the radio? What happens when you try the “Test CAT” and “Test PTT” in WSJT-X?
WSJT-X receives fine, but “transmits” to the PC speakers, since it can’t “see” the USB bridge driver. The “Test CAT” and Test PTT” indicate normal function. WSJT-X just can’t “find” the USB driver that my Device Manager says is present and normally functioning. HRD seems to find this driver just fine. I tried rolling back WSJT-X to 1.9, without benefit (went back to 2.01) and tried disabling the Windows firewall, without benefit. I have the latest driver.
Okay, so it comes out of your PC speakers. That usually means it is in the WSJT-X Audio tab and Soundcard settings, but if those are correct then it could be a Win10 problem.
Have WSJT-X open. Right click on the speaker icon in the task bar and select open sound settings. From the Sound page go to the bottom and click on “Advanced sound options – App volume and device preferences”. You’ll see WSJT-X under “App”. For the Output and Input, choose “Default” from the drop down list. Close it, close WSJT-X, launch WSJT-X, check the Audio Tab and Soundcard settings. It should be the USB Audio CODEC for Input and Output. Close the settings and try the “tune” button. It should send from your radio.
See if that will work.
Hi Rich – USB Audio CODEC shown. Still transmits the audio into the speakers. In the past, I’ve been able to find and use the Silicon Labs USB to UART Bridge driver, but now WSJT-X can’t find it. I’m not a PC guru, but I suspect the Registry is corrupted. Reinstall drivers? Rich, AE0L
If other programs work then I would not suspect the driver. Just WSJTX. Did you do a complete uninstall of WSJTX and then a fresh install? If so and it still doesn’t work then reinstalling the driver won’t hurt anything. I would do a complete uninstall of the driver and fresh install. You can find the instructions on the icom website where the USB driver download is located. See if that works.
So I have a question I am receiving a lot of stations, but no ne is hearing me. What do you set fro transmit, do I need to select something other than USB . . . RTTY . . .
Nice to hear from you and thank you for the question here.
Digital modes use USB-D. The exception being RTTY (FSK), then the radio would be in RTTY mode.
So if you are sending FT8, you should be in USB-D. If your WSJT-X is setup like mine “Mode=Data/Pkt” in settings, then it will automatically change the rig to USB-D.
If you are using something like DM780 or Fldigi you will need to put the radio in USB-D mode.
See if that makes a difference.
I will be a little more specific. I just started working with WSPR. (I am a rookie…got my extra class last summer). The first evening I got received 177 spots, but O had 0 spots on my transmissions. I ran it again yesterday, my received spots may not have uploaded, but in any event I still have 0 sports on transmission. I am wondering if I have a setting off. Using a 7610.
Thank you very much, I was able to find it, we will see if that helps.
I see Kevin. Have a look at my ICOM 7610 screen capture page. https://k0pir.us/icom-ic-7610-specifications-features/icom-7610-screen-captures/
You want to be in USB-D1 mode. Do you see any power output?
Have you tried FT8?
Thanks. I should also note I am a mac user. I have not tried FT8 yet. That is up next. Currently I am plugged into USB-. Not sure what you mean about Do I see any power output. The meter has been set to SWR, it does react in transmit mode. I am sending in two pieces the software says too long
I would try FT8. WSPR is a very low power mode. I would try FT8 and setting your radio to 30w output and put the meter in Po position so you can see the power output.
Hey Rich. I’ve tried to setup my 7300 the way you have stated, but do not get any replies from others.
I can see other transmissions. When I test the PTT in ‘radio’ It clicks the radio to send transmission, but the box turns red. Any help would be appreciated.
Nice to hear from you and thanks for commenting here.
That is what it is supposed to do. Test CAT turns green, Test PTT turns red.
Network is different DHCP is off, Default primary and @nd Server are empty No network name Network control is off. Internet access is FTTH and USB send is off and all empty
As long as DATA1 MOD is set to USB you should be good.
I cannot seem to find USB Send in the menu . . . how do you get to it. On the CI-V baud rate. I do not have a choice for 115200. 4800, 9600 19200 and auto
Thank you for commenting here, I apreciate it.
On the Icom 7300 press the hard MENU go to SET>CONNECTORS>USB SEND/KEYING. You’ll see it there.
You’ll need to Unlink from [REMOTE]. In the MENU as above CONNECTORS>CI-V, press the CI-V USB Port on the second page. Press Unlink from [REMOTE]. Now you will be able to change the CI-V USB Baud Rate.
I hope this is what you are looking for.
I have a 7610 connectors There is no option for CI-V USB Port,
On the 7610 same as before, press the hard MENU go to SET>CONNECTORS. 1st page of the menu at the bottom, USB SEND/Keying. Here are my settings on USB SEND/KEYING. Inhibit Timer was added in a later FW version and mine is set to ON.
Here are some of my other screen captures.
See if that helps.
First, thank you for all the excellent support to everyone! I have my 7300 talking with the local computer all working 100% (still learning!). Now with AnyDesk and I can hear and control the local computer (DXLab) at any remote location with my laptop. I can change things in DXLab, etc. but I can’t get the TX side on SSB to work?! RX audio is great on the remote labtop but I can’t figure out the TX and audio setup part for SSB TX.
Any help is greatly appreciated!
How about settings for JT8call?
Have you done a video on connecting to a Raspberry Pi4? I got most t work, but am struggling to get Cat button to turn green
Was having issues with setting up Codex audio/mic settings in Win10 until I found this post. Was constantly over-driving my signal on WSJT-x and could not find a good tutorial to walk me though the steps on the Win10 side. And now I know how to use the TEST button on WSJTx and watch the meters on the 7300. Great job and thank you. Expecting to make many more FT-8 contacts now that everything is working properly.
Nice to hear from you and I hope all is well where you are.
Thank you so much for commenting, I sincere;y appreciate it.
I am happy to know it helped.
Be safe, take care and best 73!
