    Here are a set of potential new frequencies that _seem_ to work a little better. Closer to JT9, but still leaving enough padding for 25 JT9 parallel signals at a time. Curious what y'all think here:
    Code:
    160m:  1.842 500 // 2.5 kHz above FT8
     80m:  3.578 500 // 5.5 kHz above FT8
     40m:  7.078 500 // 4.5 kHz above FT8
     30m: 10.130 500 // 5.5 kHz below FT8
     20m: 14.078 500 // 4.5 kHz above FT8
     17m: 18.104 500 // 4.5 kHz above FT8
     15m: 21.078 500 // 4.5 kHz above FT8
     12m: 24.922 500 // 9.5 kHz above FT8
     10m: 28.078 500 // 4.5 kHz above FT8
      6m: 50.318 500 // 5.5 kHz above FT8
    
    If you have any issues with one of these, know of any nets or observed calling frequencies here, please feel free to call it out. But, if you do, I'd really appreciate if you provide an alternate that could be used instead.

    Cheers!

    It's not as robust as PSK31 is. It's faster, and seems to work best under 4,000 miles. Sometimes can work further with it.

    The main issue I know of is going to be on the Asian side around JA. Lots of SSB going on around 7.078.5, and the ops there are pretty stubborn about talking right over the top of any digital signals that present themselves there. I hear FT8 there right now, and JA's using SSB up on 7082ish.

    Yea, that's a shared segment between CW/NB DIGI/PHONE. Could add a Region 3 drop down to 7.0385

    Hi Jordan, Great you are trying to adjust the set frequency for all the various bands...I am afraid though you might not make all happy...

    I will tell you there was a TX carrier right on top of the FT8CALL carriers (Using RTTY)..Although the band was completely wide open above 14.080...

    Cheers!

    I'll see if I can find some JA friends who speak English who can offer some input.

    80m: 3.578 500 // 5.5 kHz above FT8

    If you do that, won't they still end up on 3.580 - the PSK31 frequency? I'm not sure how much spread you're talking about. It would probably be better to put it at 3.578. That still puts it far enough away from FT8 and gives some room for the spread.

    Everything else looks good to me

    It's already the JT9 frequency +500 hz

    That's because, if it's not a contest, you'll find RTTY calling CQ there because it's where people look for RTTY. If he goes further up the band, people may not hear him because they're looking on 14.080
