Hi Skipp, I would also like to be copied on the de-emphasis information from the original GE Master Pro Repeater Audio card if you send it to Tom.
Best of holiday wishes to you and yours.

Network Examples... 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, skipp skipp025 at yahoo.com > "Tom" <[EMAIL PROTECTED]> wrote: > The 850 RX out sounds like de-emph.
