C-QUAM

Hmmmm... with the current focus (of the younger generation especially) on streaming services such as Apple and Spotify, I would doubt there would be a resurgence of 'quality' AM music. Most of the AM stations around this area (Western Canada) have become 'talk radio'. And even the FM stations are struggling.

As to whether the Flex can decode it, I would doubt it. Flex (or someone) would have to develop a waveform for it.
