    It took a while to get things right , but this software combo is an excellent choice. It makes operating and logging a breeze. Note: JTAlert 2.8.7 is the last version to support HRD V6 logging.


    In Part 1:
    03:03 Setting up Icom 7300 for receiving and transmitting JT65, JT9 and WSPR.
    Turning AGC Off! RF Power: 100%
    Setting FIL1 to 3.6K

    05:25 Starts where we connect with HRD and HRDLogbook setup.
    Auto uploads to, eQSL and

    10:10 WSJT-X setup.
    Split operation and turning off LOCK TX=RX

    Thanks for emphasizing that NR, NB and AGC should be OFF for digital modes. b. Excellent lessons, thanks.

    It was quite an adventure when I set up my TS-590S for HRD, not such a big deal for my K3s, it has a data mode which sets AGC to fast, etc.

    Doesn't the 7300 have a data mode? How do you like the rig so far?

    Hi John,
    Yes, USB-D and it's a great radio for data modes. Very easy to setup and very easy to operate. I remember using my TS-570 for BPSK and I used my TS-530s for BPSK also. A different story there, but nonetheless fun!

    Thank you for sharing the video. Very informative and I learned that my FIL1 filter was set at 1200. Now I'll have to reset the other filters as well since I like to use them for weak signals when the band is busy. The waterfall is more even with the wider filter and decoding JT65/JT9 is now possible across a much wider bandwidth. Very cool.

    I've been running the 7300 with HRD, WSJT-X and JT for a couple months and HRD/JT65-HF prior to that. It seems to be working reliably for the most part but, that's not saying there isn't room for improvement. The initial set-up can be confusing and their wasn't much reliable IC-7300 digital mode set-up information available back in September when I got the rig. At least I wasn't finding it.

    My rig settings differ from yours but, so does my configuration with a single USB cable for both USB and CIV data.

    Other than your settings for separate USB/CIV, the settings that differ on my 7300 are:
    -USB AF Output Level at 10%
    -ACC MOD Level at 60%
    -USB MOD Level at 27%

    Perhaps this depends to some extent on the PC audio level configuration as well so here are those settings.
    -Speakers (Codec) level at 90%
    -Microphone (Codec) at 48%

    The audio level into the PC is obviously quiet strong in spite of the modest settings at both the rig and PC. I would welcome any thoughts and suggestions unless you feel that this is distracting from your topic. I'm happy to take this offline if you prefer.

    Hi Dave,

    Yes, I've been using the Audio CODEC for some recording and just as you say, it depends on the PC too. I'm still playing around with it and haven't got it where I want it for that. I've had those settings all over the place. LOL, It's a work in progress.

    Glad you found it useful. It's a lot of fun finding new ways to do things and I did get useful tips off of the WSJT-X Facebook group. Turning the AGC completely off and RF Gain down a little made a noticeable difference in decoding.

    I couldn't get the wide-graph looking good and that's where the WSJT-X manual really helped out. So everything comes from a variety of sources.

    Thanks Dave, I hope that answered it for you. You can always shoot me an e-mail or comment on my site. I'd be happy to hear from you.

    No problem loading or getting the 7300 to work. 21 days after new,
    you could not change bands. ICOM said they had two others with
    the same problem. Not a good way to start.

    Yes, that would be very disappointing. I haven't heard that before. I'm curious to see how the IC 7610 fares.

    My rig still has AGC turned on due to strong signals (-1 dB to +10 dB) out of California and Arizona. For the most part they are probably not running excessive power as I often see my signal at -1dB in CA & AZ even at QRP power levels.

    Turning down the gain helps a lot with decodes. Using a narrower filter and offsetting the frequency at the rig also helps decoding weak signals when other strong signals are present. For example on 30 meters there are often strong signals around a frequency offset of 2000. To improve receiver sensitivity you can tune the rig to 10.750 MHz and use the 1.2k filter. This shifts the strong signals to 2500 which is outside of the bandpass. Of course you need to remember the everything is shifted so an offset of 500 is now actually 0. The PBT filter with or without a frequency offset can be used in a similar fashion.

    Maybe someone has some tricks but, I doubt if a wide waterfall display will ever look as good as a narrower waterfall due to the increased pixel binning. Once 4K displays are commonplace this won't be an issue any longer. I'm running three 27" monitors at 1920x1080 and the wide waterfall is Ok at this resolution but, it took some tweaking.

    Hey Dave that looks great and at that resolution, it is impressive. It's nice to see what it can look like.

    Others have mentioned narrowing the filter and I have done it a couple of times just to try. If there are strong adjacent signals it should be very helpful and another Ham told me it makes weak signals pop out too. I haven't tried tuning lower as you mentioned though and that sounds very interesting. I'll keep it in mind and try it.

    Those operating techniques could be called "Advanced WSJT-X Operation", hi hi. I see a new video on the horizon :)

    Thanks for sharing those snapshots and ideas.

    Best 73 and see you on the bands!
