Bill,
Thanks for the pointers and the reply.
I think the software solution will work, I have done some testing. I will
still investigate those URLs you provided. I will keep you posted.
ps
All options are relative. That's way I ask for them.

We are dealing with cheap HAMs here after all! So supplying everyone
with
a mic is going to be costly to begin with. A preamp, which is the best
solution, will be too costly. So I need to build a software fix.
It's been a long time since I was at all active in Amateur Radio.
But from my memory, which is mostly washed away by gin and vermouth,
some, if not all, Hams are avid electronic tinkerers. The web is filled
with little preamp circuits you can build with three transistors and
a 9v battery, and can put in an Altoids tin. Wouldn't this be a better
solution than fooling with software. How many of them to you need,
after all?
Here's a list of some you might look at:

($5 mic preamp, which the article claims competes
favorably with a $1500 preamp. I have no idea
if it is smoke or mirrors or both.)

(Related to the previous)
I got these by searching for "preamp" on digg.
P.S. After I wrote this reply I actually looked at the
other replies, so this is not completely relevant.
