JS8Call – Why? What’s New? and Download Link

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.

    Unless someone comes up with a structure for competition JS8 will set on the sidelines as FT8 continues to attract significant activity. FT8 already had a competitive structure – the Contest. Unless JS8 can offer a form of competition that is more efficient than FT8 it will remain on the sidelines.

    Let us hope that JS8 can foster some competition structure that will contribute to the market for Ham Radio products.

      Hi Dick,

      Nice to hear from you and well put!

      I have not downloaded the beta of WSJT-X yet, but I’m looking forward to it.

        Hi Rich,

        Tim Kraus/KC4ZGP here.

        I downloaded a windows version 0.7.3 from the group thing. It says it expires in fourteen days unless I upgrade. Where’s the upgrade button?

        I see waterfalls but decode nothing.

        Thanks.

          Hi Tim,

          Nice to hear from you and yes the expiring is common until the finial versions are out. Jordan will have an update on that same page you downloaded it from.

          I’m on 7.078 right now and decoding signals. Sometimes there won’t be anything or anyone on. Is your time synced on your computer?

            Hello Rich. Thank you for the fast reply.

            Time synced on the computer? Do you mean the software and computer time match? The software has it’s own clock? OK. I’ll look for the sync thing when I get home.

            Oh boy! I’m having fun…I think.

            Say hey to the family.

            I have a Windows PC and use NetTime. It syncs my PC time so the TX/RX in the software is spot on.

            Eureka, I went to 7.078 and call signs began to show.

            Learning things like it sends in blocks. Send button says 1/4, 3/5. I stopping it manually after it unkeyed.

            Decoding still an issue.

            I’ll be on 7.078 this evening. Maybe we’ll decode together.

    JS8 is not for contesting, but more for chatting IMO. It has great potential, but I hope it evolves to something more streamlined for two way chat, than today’s version.

    • K0PIR says:

      Hi and thank you for commenting. I can see your point and two way chat is nice. It takes a little time to understand how it works in a QSO, but the more time I spend with it the better I understand it.

      The auto is a little confusing at times. I found myself having a QSO with a station on auto mode, HI HI!

      Maybe there is some potential for emergency communications with JS8.

      Thank you again and 73,
      Rich, K0PIR

    It is my opinion that JS8 will bury FT8. FT8 with chat…what is there not to like? Contests, schmontests. That is just a more automated version of FT8, if that were possible.

    • K0PIR says:

      Hi,

      Nice to hear from you!

      WSJT-X is further along and offers much more. JS8Call just does JS8.

      I’m anxious to use FT8 in a contest, just for kicks.

    I found chatting to be cumbersome. One good sentence would cause 5 uploads, I think 15 second segments. I might be missing the main point of JS8 but PSK still looks pretty good to me.

    Hi Brad,

    I have found the same. There seems to be a lot of stations using AUTO and BEACON, only a few to have a QSO with.

    I’m still working at it because there seems to be a lot of interest right now.

    I agree I could have had easier PSK31 QSOs. Is there a PSK contest coming up, I hope so. 🙂

    P.S. I am having a QSO with WD9DUI right now and it is going very nicely!

    7.078??

    I think I just figured out something. I was looking at waterfalls a tad above Olivia at 7.072. I should tune higher eh.

    I’ll let you know.

    Thanks.

    Now I understand the clock synchronizing thing.

    NIST via internet and my windows 10 automatic setting feature did the trick.

    Olivia what? PSK-31 what? Huh

    Have fun folks and be patient.

    been trying to download the new js8 program into my new lenovo e495 laptop and can’t seem to get it to download.

    Hi Clyde,
    Head over to the JS8Call support on Facebook or Groups.io. See if others are having a problem.

    I am on the “Road to QuartzFest”.
