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

Tres Bien! Gorgeous - I really like the professional punched panel and neat layout. I've never been known for such neatness...

Nice job! I was always intrigued by the Pira design, as it seems better than what's found in the SG-165 and other "service grade" generators.

For those who'd be interested to get more detailed information
about my FM encoder project I just created 2 new YouTube videos
about this project. You will be able to see the encoder in action.

And please.. forgive my french accent.. I did my best.
Cheers !

Hello. I looked at your projects directories and I am impressed. Do you have pages with descriptions of the projects?
Thanks.

Hi Alan,

All my projects can be found here:
http://www.arcenson.com/projects/

The source files (pages with description) are available for all my projects but the following:
AC Isolated power supply
FM Stereo encoder
Seeburg SC1 jukebox

These projects are described in their specific web page
with all the details and pictures needed.

All the other projects have all their source files
available for anybody to share or use..
Front panel layouts, Schematics, PCB layouts, part list,
Microcontroler C source code including their compiled .HEX files.
The actual bigger project (never ending one) is the modular synth.
I'm still adding modules in it..

Feel free to ask any questions.
J-Pierre
