First went with a Channel Master table radio that had a mux adapter output, and the second went in a Bradford consolette radio/phono I got from a couple at church. It's now in a Pennsylvania dentist's hands.

Fascinating. I may have to try that (if I can source the chips).

I built a project in school to decode and re-generate MTS stereo from a composite audio input, using my Sony 7" TV-720 to demonstrate.
It was easier to adapt an NTE-743, which is a similar IC to the MC1310, a Motorola chip.

As I fuzzily recall 30 years later, the range of the pilot tone generator on the NTE (an LM-something) could be tuned to 15.7 kHz. But the Motorola IC was designed to be stable at 19 kHz and varying it did not work well.

March 1986 Radio-Electronics has the project for an MTS Stereo decoder using the MC1310 - it's a versatile chip....

I done that project too.It was great to hear the Tonight Show and Miami Vice in stereo.
