Subject: [Premium-Rx] Siemens chip info needed

Hi all ...

Michael O'Beirne also sent me a couple of papers on a rather nice AM 
synchronous demodulator circuit - high performance and fairly 
straightforward. However, it calls for a chip (probably the only critical 
part in the thing) that is out of production. It's the Siemens SO41P high 
performance FM discriminator. Does anyone have a spec sheet for this beast? 
Any thoughts on a possible substitute?

73s, Jan
