Default discriminator


I have a question about discriminator tapping, and please don't tell me
to read up on in because I belive I have read all the web pages, the
problem is that they are not consistent.

Bill Cheeks seems to recomment a capacitor in line with the
discriminator tap, but even he seems unclear on the recommended value.
It seems to vary from 0.1 to 10 uF depending on who you talk to, other's
say you don't need it at all. A more recent post recommends a 10 K
resistor instead. Also a small 0.001 uF cap is recommended by some folks
connecting the tap and ground.

I am successfully monitoring pocsag and flex with none of this, but
obviously there is always room for improvement. So everybody's opinions
on this are hereby solicitied.

Also, it looks like I should build a data slicer; at this time I am
using my sound card.
