I'm a little at a loss as how to "chuck" a low noise mmic in front. I
thought these were reserved for higher frequencies. I had trouble
finding much info as to how I could use one. I did find this little
guy as an alternative:

Amtel ATR5261
http://www.atmel.com/dyn/resources/p...ts/doc4913.pdf

Could I use that as a low noise amp?

And to clarify, I could have some connection such as: antenna ----
lownoiseamp ------ MK484 ------ amplifier (LM386?) ------
speaker

Thanks for bearing with my limited knowledge. I think it could be
useful little deal if it ever turns out.
