[hpsdr] Mercury v2.4 -- still distorted audio

[Doug Bade]

I guess I do not think a dual core hyper-threading 1.6ghz processor 
with usb 2.0, 2gb ddr2 and a 566 FSB subsystem is severely 
limited.... it is far more mips than my first PowerSDR computer...

Especially in light of Phil Covington and others comments that it can 
do the job fine if the code is optimized (as apparently some other 
code has been) ....

We can more often than not fix a processing problem by throwing more 
mips at it, generating more heat and larger boards....   but it does 
not take a 12 GA to hunt mice....although that works too....

Some of us are looking for quasi embedded solutions and a 13w 
processor on a 7x7 pcb looks really nice for field day... even if I 
have to trade 192k/1024 or 96k/2048 for the luxury of not dragging my 
Q6600 quad core box around.. so be it... but if some code 
optimization and/or bug-age can be located and corrected.. I will be 
a happy camper... I own 3 Q6600 based computers, albeit tasked for 
other things, none of them is remotely as portable as the Atom 330 
box.. nor intended to be...

It seems like the hardware is magnifying another issue.... not THE 
actual issue...

It sounds like we have a solution coming that will address other 
things as well from comments I have seen on this thread.. I for one 
will be quite content to wait until it happens.. and am NOT unhappy 
now. I guess we all have different mission requirements....
