Needing some help with JT65-HF

Ok all you JT-65 op's out there I have some questions about my setup here at VE3WDM using the new release of WSJT-X ver 1.6.0. Here is what I am using in my setup- Elecraft k3 in DATA A mode, Signalink USB, Windows 7 and finally as I said WSJT-65 ver 1.6.0. Tigertronics has a great web page for setting up the sound card for Windows 7. I followed all the step and all seemed to go well until I noticed one setting keeps reverting back to a default setting. Once I go to the step "Setting the windows software playback levels" you are instructed to set WSTJ's sound level to 50% which I did. I kept this window open but notice once the WSJT program came out of transmit the WSJT volume reset to 100% and stays there? To get the setting back to 50% you have to manually reset the volume but once again it resets to 100% after
Reset sound setting?
transmitting. The other issue is my waterfall and really at this point Im really not sure if it's a issue or lack of knowledge of this mode. I have seen on many Youtube videos of a nice blue waterfall with yellow and red JT-65 signals. My waterfall has two very large "signals" on the left and right of the waterfall. The first picture (PIC-1) is with the signalink RX at zero so there is no decodes (that makes sense) but what are the "things to the left and right on the waterfall?

As I turned the volume setting on the Signalink to 9 o'clock I was able to see decodes but the mystery signals were still present on the left and right to the waterfall. This can be seen in PIC-2 but then just an hour later with all settings the same what waterfall looks like PIC-3!

So I'm not really sure what is going on with the receive RX and why the sound setting is getting reset from 50% to 100% after each transmission. Any input would be a great help to getting this mode up and running.

  1. Hello Mike, I really think this is a hardware modem problem. I'm not really familiar with tigertronics but I believe it has a internal soundcard so a driver does enable it to connect to windows. I can't remember I've seen this before but could it be something between the radio and modem, loose connector, connector not far enough into the modem, defective connector? I can't think of anything else actually or it has to be a wrong filter setting in the radio, I doubt that. A strange thing is that the tigertronics soundcard is resetting to 100% after you transmit. Could it be a wrong driver? You didn't mix up the LINE-IN and LINE-OUT? Hope you'll find the problem. 73, Bas

    1. Good morning Bas, thanks very much for the advice and I have checked all connections and they are good. I have done some searching online and there seems to be some settings for the sound in Win7. I have done a few of the changes but it has made no difference. Well I will keep looking and see what comes up.
      Have a great week Bas

  2. Hi, I am also using Signalink with Win 7 without problems. I have made the following fix however:

    1. Nice to hear from you Panagiotis, thanks very much for the link and as I viewed it I did realize I had done exactly what was in he youtube video. I had gone to the slider and taken it as close to zero and hit "ok" as "apply" was greyed out. I found that when I went back to this window to check the DB setting it had changed and was no longer close to Zero but back up were it originally was.

  3. Hi Mike, in order to avoid left big signals try making Start = 200Hz instead of zero, maybe helps.

    1. Good afternoon, I have somehow got JT65 HF up and going and making contacts and have sorted out the waterfall. I still have the start at "0" but what does increasing it to 200 do??

  4. Its recomended in the manual: 6.2. Wide Graph Settings

    This solved a similar problem of mine. 73 de SV1GRN
