Hi Guys,
I've really enjoyed the posts about Commercial Sound Cards as I want to
improve my RTTY weak signal reception.
I've got some questions:
1) Some people contend that Internal sound cards are more prone to "noise
and interference" then External sound cards... and therefore External sound
cards are better.
Others contend that the USB sound card is more likely to have latency
problems, especially if a number of USB devices are plugged into the computer,
and therefore the Internal sound card is better. I imagine both issues
depend on a variety of things like how "noisy" the computer is and the
environment the computer is located in. But isn't there a concensus on
whether
the Internal or External sound card generally works better on RTTY reception
for most people? Or are External sound cards and USB sound cards so new
that the jury is still out?
2) Are some Desktop computers known to have a lower internal signal to
noise ratio? If so, what Makes & Models are best?
32) Would an internal Broadcast quality sound card like the Digigram
VX-222 that has a S/N ratio of >-95dB, and very low distortion such as 0.002%,
when installed in the average consumer desktop computer, provide a good deal
better weak signal reception of RTTY signals?
Hope to work you this weekend in the OK RTTY DX Contest.
73,
Dick- K9OM
