Tony,
First make sure that you have a good audio connection from Line Out to
the soundcard. Use good quality cables that do not pick up noise.
What happens if you eliminate the Signalink - change HRD to use the
computer default soundcard and connect from that soundcard line out to
the K3 Line In - if decode is OK under that situation, look for the
problem in the Signalink soundcard.
The built-in soundcard in most modern computers is one of the HD types,
and is much more than sufficient for use with data modes.
On troubleshooting -- When you have a problem, suspect everything and
eliminate the possible suspects one at a time. Substitution is always a
good analysis tool.

Hi Sal,
Yes, I went through the Signalink audio level config again and no change.
The Signalink pots are also set just like yours.

Hi Tony!
Have you gone through the Signalink audio levels config procedure?
Is it possible that its just Windows audio levels that are low?
All my Signalink pots (except Delay) are usually at 12 o'clock.

Folks,
I decided to try HRD/DM780 for first time after using another HF
digital software program for
probably 10 years. I am using an Elecraft K3 and a SignaLink USB
interface and both
MixW and MultiPSK fine with ZERO problems on either RX or TX. With
HRD/DM780 (version 6.2) the K3
will TX fine (great signal reports), but on RX (with the Audio
input set between 50-60%), I only get about
90% copy even with a solid OLIVIA signal in the waterfall. I have
tried all kinds of SYNC/TUNE Margins
(while using OLIVIA) to no avail. I have also tried all different
levels of audio RX input to no avail.
If someone could share their SignaLink and any K3 LINE-IN/LINE-OUT
config values to get DM780 to work I
would appreciate it. I have been at this for a week (part time) and
still can't get DM780 to work correctly
with my K3.
There is clearly a parameter I am missing, but the documentation for
setting up the soundcard for version
is 6.2 is a tad vague.
