Interesting. What led you to choose the AN7418S?
How hard was it to work with given it appears to be surface mount?
I am interested because I've built a couple solid-state MPX decoders based on the LM4500 IC, which itself is now obsolete and hard to find. So if there is a good chip which can be used to build a board based on an available IC, I am definitely interested - assuming it works well with good separation. I see it has a connection for an optional separation control, which is a plus for some of those early Fisher tube-type FM tuners.
It appears that you added some transistors - to amplify the signal going into the MPX decoder chip? Do you have a diagram you can share? Thanks.
