Hi Tom, 

The simple answer is you only need a resistor and a capacitor 
to make a basic de-emph network.  

The next in line simple de-emph network would be some type 
of active device (transistor or op-amplifier) with a de-emph 
feedback layout. 

Keep in mind the de-emph networks don't remove the ctcss (sub 
tone). 

If you want a few resistor-capacitor values to try... email me 
direct and I'll set you up.  No, I didn't engineer them... I 
"lifted" the values I'll give you from the original GE Master 
Pro Repeater Audio card. Hard to re-invent something that works 
so well...  (original credit where it's due).

cheers,
