    Default JT9 Frequency Consensus

    Operating JT9 it appears the working frequencies for 10m is 28078, 15m is 21078, 20m is 14078 and 30m is 10130.

    I've seen freqs for 40m as 7039 and 7073, 80m as 3581 and 3575 and 160m as 1839.5 (weird).

    Any consensus for 40,80 and 160?

    Maybe 7078, 3578 and 1840? Basically all 2 above JT65 freqs.

    Signals are easy to find when there is a set freq such as on 10,15,20 and 30m.

    Just some thoughts looking for discussion since JT9 is a relatively new mode.

    For a JT9 forum and skeds check out: http://www.obriensweb.com/sked/index...d=digitalradio

    Thanks to ANDY, K3UK, for this site.

    If you enjoy QRP check out JT9. I've worked France, Belguim and Wales with 5 watts from Oregon..some have used less power.

    I usually find JT9 a couple of KC above JT65, just as you have them.

    It appears 18104 is the 17m frequency for JT9

    Thumbs up

    Randy it would be easy to remember two kilohertz above the JT65 7078-3578 -1840
    I'm for it!

    fashion is very interesting, you can run low power

    Vlad, I agree. Let's hope it works out that way. Perhaps K3UK can list those frequencies on his digitalradio web site.

    Well, I set up WSJT-X and I tried the test file OK. I did not see where to set TOL to 20 however. I guess I can look for sigs tomorrow as I hear none now. The program does show time and drift, etc but no stations heard. I assume I keep the rig in USB as I do in JT65-HF.

    The TOL setting is just to right of the time/date box. Yes, USB same as JT65.
    I believe 14078 is the most popular frequency, for me anyway, as I use a 10-15-20m beam. 10130 is another popular frequency.

    Check into the K3UK forum site (see above for link) when operating or just to see who's on. This site helps when working stations for coordination, etc.

    As mentioned, JT9-1 is great for QRP...from Oregon I've worked EU and Venezuela with 5 watts...plus I worked a station in Florida that was using 500mw.

    Great! How could I have not seen the TOL!! Also, I do use k3uk, but the JT9 is spotty on LOTW page of that site. I will look again now. I am looking to just rcv as I do not have my antenna(s) up yet. I did try JT65 on 10 and 15 and worked JA and KL8 using a dipole in my room as an "L".

    Anyway, thank you again...and when I got my W6 call I was in Saratoga, CA. Best setup I ever had!

    OK, well, I hear nothing but RTTY on 21078 and 14078. I assume I tune there and keep FREQ at 1500, but I see nothing on waterfall but the RTTY. I also get nothing at all on 10130...perhaps later.

    Well, I heard 2 strong stations on 14078. Sounded like JT65 but would not decode. So I switched to JT65 and they WERE on JT65 and not JT9. Was Kl7 and a 5. OH well, I still do not know if JT9 will rcv. Do I keep the freq at 14078 USB with the waterfall on 1500? Will it decode all in the passband like JT65?
