Hi Jay,
I have seen same problem, and this happens if I have used wrong soundcard
(Flex Radio 5000 SPDIF) on the TX or input on DM780 or other digital
Software.
In my case is DM 780 setup for:
Input device is Virtual Cable 2 and Source is Line, Output Device is Virtual
Cable 1 and Device Wave.
Be sure to put your wish(S) on the features requests list. Later this month,
we will use the list to develop a priority list of features for inclusion in
upcoming releases of PowerSDR.

Mismatch doesn't affect shielding.
If you transition from your balanced openwire line to the pair of coaxes,
there's no reason why there should be any currents on the outside of the
coax shield. If there were, you could always choke it with the usual
appropriate ferrite or powdered metal cores.
Interesting...
What sort of antenna and feeder design do you have? Do you have the preamp
on?

One solution to this may be to make sure that the built in soundcard is
selected as the default device (rather than the FLEX-5000 audio or VAC).

I hesitate to comment on this topic since already today my ideas on various
subjects have been strenuously rejected but to carry the discussion to the
extreme of shortness I would mention that when I consider feedlines, rather

The bottom line is that using the same mic, there is no audio quality or
character differences between using balanced vs. unbalanced configuration
assuming there are no other factors affecting the audio quality, such as a
ground loop or RFI.

Assuming a low impedance mic and input and equal shielding, balanced
will always pick up less interference (common mode cancels out). We
frequently use 75 and 100 foot mike cable runs when recording performers
without an issue.

I am selling my Flex SDR-5000A. The radio is immaculate. I am the

Have been following this line for a while, going back to the original
question, about audio quality being better using a balanced mic or a

I have two 5000As and they both went deaf when it started snowing. TenTec
Orion and Icom Pro performed normally. I assume it must have been the static
from snow. Is this a weak point with the RX? What can I do to prevent it
happening again and again? This is a third time SDR5000A went deaf.
If I had any sanity, I'd have stayed with my DX100 and HQ101.
Compre Vous?
LOL

I'm guessing that it will run on Windows, Mac, and Linux.

If I had any, I never would have started down this road and I certainly

Seriously, use this at your own risk. We are really hanging it out
there with this, trying all sorts of stuff with the new IDE.
