Re: [digitalradio] A "sneak peak" ... The microHAM DIGI KEYER:

[Dr. Howard S. White]

Yes Definitely a significant 
difference...
 
I ran parallel testing a while ago with virtually 
every interface then on the market in trying to discover an interface to 
standardize on for our Emcomm Group.
 
Two different but indentical computers, in 
parallel, two different interfaces, connected to the same radio.
 
RigExpert and External Sound Cards would decode 
signal about 6db  to 10 db better that those using the internal sound 
cards...we could copy signals 100% on RigExpert, etc when devices such as 
RigBlaster no longer copied anthing.
 
We finally traced it back to the fact that the 
internal sound cards lived inside a very noisy environment inside the 
computers... even using an external sound card, greatly improved the 
results....
So yes it does matter...  and at that time we standardized on the 
RigExpert.
 
Obviously I am hoping the new microHam device has a 48KHz or faster clock 
and I am intrigued by the statement that it does not need special 
drivers....
