Default Introducing my new humble FM Stereo Encoder project..

Hi guys,

I just finished my new FM Stereo Encoder project based on the PIRA CZ stereo encoder. http://www.pira.cz/eng/stk2en.htm
I use it with my old reliable Marconi 2022E RF generator (connected to its external modulation input) to generate a nice and sharp Stereo encoded FM audio signal to some of my vintage FM radio to be repaired and aligned.
I had to build an interface to connect to the PIRA encoder and also added a switchable 500hz tones to test channel separations.
This project of mine is viewable here: http://www.arcenson.com/projects/FM_Stereo_Encoder/

Enjoy !
Jean-Pierre
