Hi Bill and all,
Hi Joe,
The email exchanges copied below provide an example of a case in which
48000 Hz sampling fails to work, and we can't blame it on Vista.
N4AU is using Win/XP and a SignaLink interface. When he put
[Tune]
Audio\DisableInputResampling=true
into his wsjtx.ini file, his setup started working.
I wonder if he had a default sample rate on his sound card input that is
different from others. If it were 44.1kHz for example. I think the same
broken upsampling that caused Vista problems might be kicking in.
We might think about adding an option for 12000 or 48000 Hz input
sampling on the configuration screen. Possibly for both input and
output?
That would be easy to implement for i/p, the hardest part would coming
up with a short unambiguous label for the checkbox. Output wouldn't be
much harder and would lighten the load a bit for CPU cycle challenged
systems.
I would like to know which o/s and CODEC settings combinations cause the
48kHz i/p rate to cause issues.
We don't really want to get too far down the slope of creating a general
purpose rate converter :(
FYI: I'll be away and out of email contact from tomorrow through
October 18.

That did it Joe! Many thanks for the great programs. I wish more
would use
WSJTX. PSK Reporter shows about 80% still using JT65hf.
Thanks and 73,
Bobby

OK Bobby. I guess I misunderstood what you meant by "3556 works very
well".
You can force r3590 to sample at 12000 Hz (as done in r3556) by putting
the following two lines at the end of your file wsjtx.ini:
[Tune]
Audio\DisableInputResampling=true
You can do this by using Windows Notepad to open wsjtx.ini (in your
WSJT-X
installation directory). Then copy-and-paste the two lines into the
file,
and save the file.

OK Joe. Neither decodes in 3556. I think it is the Signalink, but it
does operate at 48000 in some other modes. The screen capture shows
both
waves in the waterfall display.

Joe, 3590 will decode the samples (JT9 mode only if in JT9 for the
first
file). It doesn't decode from the radio or from my saved files. It
might
be the Signalink Audio CODEC. I see you changed the sample rate to
48000
in the newer version. I have captured my screen and included a couple
of
my wav files. It's no big deal since 3556 works very well. Clock is
always ok (use ntp).
You say revision 3556 works very well. Could you send me a screen shot
of decodes from either one of the wav fkiles you sent me, using
r3556 ?
Thanks!

Hi Joe and all,
I have nice traces in v3587 and 3590 but NO decodes. I am running XP
(3) and signalink with Kenwood TS570 and v 3556 works fine. Any
suggestions?
