Q1. Does experience suggest that there can be an observable operational
gain in using a sound card different from that built into the PC?
DRV> Depends on built-in card, laptops are usually foul as are soundcards on
the motherboard in general (generalisation).
Q2. Which published technical specifications of a sound card are relevant
to digimode operation?
DRV> Dynamic range, for example:

Q3. On the basis of the answer to Q2, how does one judge whether one
sound card is "better" than another for digimode operation?
DRV> Less intermod, less noise, less spurious signals. Less problems due to
strong adjacent signals.
Q4. Do list members have specific recommendations for cost-effective
external sound cards? (The sound card suggested by Simon costs around as
much in the UK as the 100W upgrade for the basic K3.)
DRV> External is a good idea as you can take it with you and it avoids noise
from the PC. SignaLink USB is good enough, don't know whether there is a K3
cable yet. FWIW the Delta-44 is GBP85 in the UK.
