HRD/DM-780, Elecraft K3 and soundcard

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.

73,
Tony L. (KJ5XF)

Tony…

There is a SQUELCH slider near the top above the receive window (grayish horizontal bar moving). My slider was in the middle and when I moved the slider to the left all the way, I had solid copy. Where is yours set at?

Hi Gerald,
My K3 is indeed set to Data Mode. The bandwidth is set correctly and I
also have the default settings.
I also have re-installed HRD/DM780.... I also re-checked the Signalink
soundcard settings and they are OK.
Still no go... TX is fine, RX drops characters.

Hi Steve,
I had the slider at about 25% and I moved it all the way to the left.
Still no change.

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

Re: HRD/DM-780, Elecraft K3 and soundcard

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.

Looking at what I sent, I got Line In and Line Out reversed.
Tony is having problems decoding, so the Soundcard Line In and the K3
Line Out are the ones that are to be moved to the computer built-in
soundcard.

Re: HRD/DM-780, Elecraft K3 and soundcard

Folks,
I want to thank _/*ALL*/_ of you who sent feedback!!! I narrowed the
issue I was having with the RX
down to the the following:

a) The SQUELCH default (25%) was simply too high. I lowered it to 4%
b) For some interesting reason, I had to drop the audio input down to
about 15%. This level
is WAYYYY lower than what I need on either MixW or MultiPsk.

With the 2 tweaks mentioned above, now copy is where it should. That's
what I really enjoy
about this Elecraft email list. Lots of good feedback...

73,
Tony Lyon (KJ5XF)
