Hi Keith,
The audio codec used int he FT-991 is a Burr Brown (Texas Instruments)

input level is low. I have built a few home made audio interfaces with
these chips and all of them suffer from this spur. The only way to mitig

Hi Joe,
I've compiled the SVN head and am using it. The level meter color looks
good, but it may be a little better if the green could be a little darker
to have better contrast with the widget grey background. Can you try a
QColor(85,170,85) and see if it looks ok for you?
I agree with Keith's c
nt dynamic
range. The best soundcard was, at the time, the Delta 44. It has almost no
controls.

Hi Bill,
The concern I have is if the control of the OS fader would be OS agnostic.
Also, some multi input/output soundcards have a collection of controls --
some independent some not. Also, some soundcards have no hardware fader

Hello Joe and Mike,
Since I was the one who implemented the level meter, I have a suggestion:
Please don't make the level meter change colors depending of the dB level.

It is perhaps better to change the color of the text

60m is a worldwide mess. Here in Brazil the regulators are about to
authorize the segment 5351.6 kHz to 5366.5 kHz. I think eventually we could
implement a one-band frequency hopping feature for multiple receive windows
and one transmit window on 60m.

Hello everyone,
I have been monitoring using wsjt-x v1.7.0 r6286 and am noticing that the
JT65 decoder is not showing signal strengths stronger than -1 dB. Even with
very strong signals the decoder shows -1 dB. The JT9 decoder does show
signal strengths above 0 dB.

Would it add too much complexity to have the frequency error correction in

It would be quite nice to have WSPR integrated in WSJT-X. However, I think
